WARNINGS

Pay Attention to These Terms

  DANGER| Indicates the presence of immediate hazards which will cause severe personal injury, death, or substantial property damage if ignored.
---|---
WARNING| Indicates the presence of hazards or unsafe practices which could cause severe personal injury, death, or substantial property damage if ignored.
  CAUTION| Indicates the presence of hazards or unsafe practices which could cause minor personal injury or product or property damage if ignored.
CAUTION| CAUTION used without the warning alert symbol indicates a potentially hazardous condition that could cause minor personal injury or product or property damage if ignored.
NOTE| Indicates special instructions on installation, operation, or maintenance that are important but not related to personal injury hazards.

WARNING: To minimize the possibility of improper operation, serious personal injury, fire, or damage to the heater:

• Always keep the area around the heater free of combustible materials, gasoline, and other flammable liquids and vapors.
• The heater should never be covered or have any blockage to the flow of fresh air to the heater.

WARNING: This unit contains refractory ceramic fiber (RCF) insulation in the combustion chamber. RCF, as manufactured, does not contain respirable crystalline silica. However, following sustained exposure to very high temperatures [greater than 2192°F (1200°C), the RCF can transform into crystalline silica (cristobalite). The International Agency for Research on Cancer (IARC) has classified the inhalation of crystalline silica (cristobalite) as carcinogenic to humans. When removing the burner or heat exchanger, take precautions to avoid creating airborne dust and avoid inhaling airborne fibers. When cleaning spills, use wet sweeping or High-Efficiency Particulate Air (HEPA) filtered vacuum to minimize airborne dust. Use feasible engineering controls such as local exhaust ventilation or dust collecting systems to minimize airborne dust. Wear appropriate personal protective equipment including gloves, safety glasses with side shields, and appropriate NIOSH-certified respiratory protection, to avoid inhalation of airborne dust and airborne fiber particles.
WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause property damage, personal injury or loss of life. Installation and service must be performed by a qualified installer, service agency, or gas supplier.
WARNING: Gasoline, as well as other flammable materials and liquids (adhesives, solvents, etc.), and the vapors they produce, are extremely dangerous. Do not handle, use, or store gasoline or other flammable or combustible materials in the vicinity of a heater.
WARNING: Both natural gas and propane have an odorant added to aid in detecting a gas leak. Some people may not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar with the smell of natural gas or propane, ask your local gas supplier. Other conditions, such as “odorant fade,” which causes the odorant to diminish in intensity, can also hide, camouflage, or otherwise make detecting a gas leak by smell more difficult.
WARNING: UL-recognized fuel gas detectors are recommended in all enclosed propane and natural gas applications wherein there is a potential for an explosive mixture of fuel gas to accumulate and their installation should be in accordance with the detector manufacturer’s recommendations and/or local laws, rules, regulations, or customs.
WARNING: Do not install within 3 feet (0.9 m) of a heat pump or an outdoor condensing unit. Strong air intake from this type of equipment can disturb the combustion process and cause damage or personal injury.
WARNING: The heater shall not be located in an area where water sprinklers, or other devices, may cause water to spray through the cabinet louvers and into the heater. This could cause internal rusting or damage electrical components, causing damage that will not be covered under the warranty.

General Safety
Elevated water temperature can be hazardous. TheU.S. Consumer Product Safety Commission has these guidelines:

1. Spa water temperatures should never exceed 104°F (40°C). A temperature of 100°F (38°C) is considered safe for a healthy adult. Special caution is suggested for young children.
2. Drinking alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness and subsequently result in drowning.
3. Pregnant Women Beware! Soaking in water over 102°F (39°C) can cause fetal damage during the first three months of pregnancy resulting in the birth of a brain-damaged or deformed child. Pregnant women should stick to the 100°F (38°C) maximum rule.
4. Before entering the spa or hot tub, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4°F (2.2°C).
5. Persons with a medical history of heart disease, circulatory problems, diabetes, or blood pressure problems should obtain a physician’s advice before using spas or hot tubs.
6. Persons taking medications that induce drowsiness, such as tranquilizers, antihistamines, or anticoagulants, should not use spas or hot tubs.

WATER CHEMISTRY

NOTE: Corrosive water voids all warranties.
Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water chemistry according to Table A. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and damaging the heater. If the pH drops below 7.2, this will cause corrosion of the heat exchanger and severely damage the heater. Heat exchanger damage resulting from chemical imbalance is not covered by the warranty.
For your health and the protection of your pool equipment, it is essential that your water be chemically balanced. The following levels must be used as a guide for balanced water.

CAUTION: Free chlorine must not exceed 5 ppm which can damage the heater and is not covered under warranty.

• Occasional chemical shock dosing of the pool or spa water should not damage the heater providing the water is balanced.
• Automatic chemical dosing devices and salt chlorinators are usually more efficient in heated water, unless controlled, they can lead to excessive chlorine levels which can damage your heater.
• The check valve should be installed between the heater outlet and a chlorinator or other chemical dosing device.
• Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical supplier for the correct levels for your water.

Automatic Chlorinators and Chemical Feeders
All chemicals must be introduced and completely diluted into the pool or spa water before being circulated through the heater. Do not place sanitizing chemicals in the skimmer. High chemical concentrations will result when the pump is not running (e.g. overnight).
Chlorinators must feed downstream of the heater and have an anti-siphoning device/check valve to prevent chemical backup into the heater when the pump is shut off. See “Plumbing Diagram” on page 23.

NOTE: High chemical concentrates from feeders and chlorinators that are out of adjustment will cause rapid corrosion to the heat exchanger. Such damage is not covered under the warranty.

Derived from National Fuel Gas Code, Table 10.2.3
Table D. Reduction of Clearances to Protected Surfaces
Heaters must not be installed under an overhang of less than three 3′ (0.9 m) from the top of the heater. Three sides must be open in the area under the overhang. Roof water
drainage must be diverted away from the heaters installed under overhangs with the use of gutters.

For U.S. installations, the point from where the flue products exit the heater must be a minimum of 4′ (1.2 m) below, 4′ (1.2 m) horizontally from, or 1′ (0.3 m) above any door, window, or gravity inlet into any building. The top surface of the heater shall be at least 3′ (0.9 m) above any forced air inlet, or intake ducts located within 10′ (3 m) horizontally.
For Canadian installations, pool heaters shall not be installed with the top of the vent assembly within 10′ (3 m) below, or to either side, of any opening into the building. Refer to the latest revisions of CAN/CSA-B149.
A minimum of 6′ (1.8 m) is required from the heater to an inside corner wall for proper outdoor venting.
For installations in Florida and Texas, that must comply with the Florida or Texas Building Code, follow the directions shown in Figure 5 for the installation of hurricane tie-down brackets for all models.

Indoor Heater Installation
For Canada, indoor installation is restricted to an enclosure that is not occupied and does not directly communicate with an occupied area. Refer to the latest edition of CAN/
CSA-B149 for specific requirements. Locate the heater as close as is practical to a chimney or gas vent. The heater must always be vented to the outside. See the “Venting” section on page 13 for details. Minimum allowable space is shown on the nameplate.

Combustion and Ventilation Air
Indoor Units Only
The heater must have both combustion and ventilation air. The minimum requirements are listed in the latest edition of the National Fuel Gas Code (U.S. ANSI Z223.1 or Canada CAN/CSA-B149) and any local codes that may have jurisdiction. The most common approach is the “2-opening” method, with combustion air opening no more than 12″ (305 mm) from the floor and the ventilation opening no more than 12″ (305 mm) from the ceiling. For opening sizes using this method, see below.
All Air from Inside the Building:
Each opening shall have a minimum net free area as noted:

Table E. Opening Minimum Net Free Requirements – Indoor Air
All Air from Outdoors:
When air is supplied directly from outside the building, each opening shall have a minimum net free area as noted:

Model| Unrestricted Opening sq. in. (m ² )| Typical Screened or Louvered Opening sq. in. (m ² )| Typical Screened and Louvered Opening sq. in. (m ² )
---|---|---|---
264| 66 (0.04)| 99 (0.06)| 132 (0.09)
404| 100 (0.06)| 150 (0.1)| 200 (0.13)

Table F. Opening Minimum Net Free Requirements – Outdoor Air
CAUTION: Combustion air must not be contaminated by corrosive chemical fumes which can damage the heater. Such damage will not be covered by the warranty

Direct Vent and Ducted Combustion Air Systems
If the outside air is drawn through the intake pipe directly to the unit for combustion:

1. Connect combustion air to the heater by removing the screened cap on the air intake port, and sealing the combustion air duct to the existing PVC adapter. Glue or attach screws to fasten. The existing screen should be re-used at the intake end of the duct. Install the combustion air duct in accordance with Figure 11 or Figure 12 of this manual.

2. Provide adequate ventilation of the space occupied by the heater(s) by an opening(s) for ventilation air at the highest practical point communicating with the outdoors.
   A. In the US, the total cross-sectional area shall be at least 1 in.² of free area per 20,000 BTUH (111 mm² per kW) of total input rating of all equipment in the room when the opening is communicating directly with the outdoors or through the vertical duct(s). The total cross-sectional area shall be at least 1 in.² of free area per 10,000 BTUH (222 mm² per kW) of total input rating of all equipment in the room when the opening is communicating with the outdoors through the horizontal duct(s).
   B. In Canada, there shall be permanent air supply opening(s) having a total cross-sectional area of not less than 1 in.² of free area per 30,000 BTUH (70 mm² per kW) of the total rated input. The location of the opening(s) shall not interfere with the intended purpose of the opening(s) for the ventilation air.

3. In cold climates, and to mitigate potential freeze-up, Raypak highly recommends the installation of a motorized sealed damper to prevent the circulation of cold air through
   the heater during non-operating hours.

Florida and Texas Building Code:
Wind Speed = 180 mph 3-sec. gust
Exposure = C

WARNING: The Commonwealth of Massachusetts requires that sidewall-vented heaters, installed in every dwelling, building, or structure used in whole or in part for residential purposes, be installed using special provisions as outlined on page 49 of this manual.

Venting
CAUTION: Proper installation of flue venting is critical for the safe and efficient operation of the pool heater.

General
Appliance Categories
Heaters are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent.
Category I – A heater that operates with a non-positive vent static pressure and with a vent gas temperature that avoids excessive condensate production in the vent.
Category II – A heater that operates with a non-positive vent static pressure and with a vent gas temperature that may cause excessive condensate production in the vent.
Category III – A heater that operates with a positive vent pressure and with a vent gas temperature that avoids excessive condensate production in the vent.
Category IV – A heater that operates with a positive vent pressure and with a vent gas temperature that may cause excessive condensate production in the vent.
See Table H for appliance category requirements.

NOTE: For additional information on appliance categorization, see the ANSI Z21.13 Standard and the NFGC (U.S.), or B149 (Canada), or applicable provisions of local building codes.
WARNING: Contact the manufacturer of the vent material if there is any question about the appliance categorization and suitability of a vent material for application on a Category I vent system. Using improper venting materials can result in personal injury, death or property damage.

Table H. Venting Category Requirements

Support of Vent Stack
The weight of the vent stack or chimney must not rest on the heater vent connection. Support must be provided in compliance with applicable codes. The vent should also be installed to maintain proper clearances from combustible materials. Use insulated vent pipe spacers where the vent passes through combustible roofs and walls.

Vent Terminal Location

1. Condensate can freeze on the vent cap. Frozen condensate on the vent cap can result in a blocked flue condition.
2. Give special attention to the location of the vent termination to avoid the possibility of property damage or personal injury.
3. Gases may form a white vapor plume in winter. The plume could obstruct a window view if the termination is installed near windows.
4. Prevailing winds, in combination with below-freezing temperatures, can cause freezing of condensate and water/ice build-up on buildings, plants or roofs.
5. The bottom of the vent terminal and the air intake shall be located at least 12 in. (305 mm) above grade, including a normal snow line.
6. The un-insulated single-wall metal vent pipe shall not be used outdoors in cold climates for venting gas-fired equipment.
7. Through-the-wall vents for Category II and IV appliances and non-categorized condensing appliances shall not terminate over public walkways or over an area where condensate or vapor could create a nuisance or hazard or could be detrimental to the operation of regulators, relief valves, or other equipment. Where local experience indicates that condensate is a problem with Category I and III appliances, this provision shall also apply.
8. Locate and guard vent termination to prevent accidental contact by people or pets.
9. DO NOT terminate the vent in the window well, stairwell, alcove, courtyard or another recessed area.
10. DO NOT terminate above any door, window, or gravity air intake. Condensate can freeze, causing ice formations.
11. Locate or guard the vent to prevent condensate from damaging exterior finishes. Use a rust-resistant sheet metal backing plate against brick or masonry surfaces.
12. DO NOT extend the exposed vent pipe outside of the building beyond the minimum distance required for the vent termination. Condensate could freeze and block the vent pipe.

U.S. Installations
Refer to the latest edition of the National Fuel Gas Code. Vent termination requirements are as follows:

1. The vent must terminate at least 4 ft (1.2 m) below, 4 ft (1.2 m) horizontally from or 12 in. (305 mm) above any door, window or gravity air inlet to the building.
2. The vent must not be less than 7 ft (2.1 m) above grade when located adjacent to public walkways.
3. Terminate the vent at least 3 ft (0.9 m) above any forced air inlet located within 10 ft (3.0 m).
4. The vent must terminate at least 4 ft (1.2 m) horizontally, and in no case above or below, unless a 4 ft (1.2 m) horizontal distance is maintained from electric meters, gas meters, regulators, and relief equipment.
5. Terminate the vent at least 6 ft (1.8 m) away from adjacent walls.
6. DO NOT terminate the vent closer than 5 ft (1.5 m) below the roof overhang.
7. The vent terminal requires a 12 in. (305 mm) vent terminal clearance from the wall.
8. Terminate vent at least 12 in. (305 mm) above grade, including normal snow line.
9. Multiple direct vent installations require a 4 ft (1.2 m) clearance between the ends of vent caps located on the same horizontal plane.

Venting Installation Tips
Support piping:

• horizontal runs—at least every 5 ft (1.5 m)
• vertical runs—use braces
• under or near elbows

Venting Configurations
For heaters connected to gas vents or chimneys, vent installations shall be in accordance with the NFGC (U.S.), or B149 (Canada), or applicable provisions of local building codes.

Vertical Venting (Category I) Fan-Assisted
Installation
Natural draft venting uses the natural tendency of the heated flue gases to rise until they are expelled from the top of the flue. The negative draft must be within the range of -.01 to -.08 in. WC as measured 12 in. (305 mm) above the appliance flue outlet to ensure proper operation. Vent material must be listed by a nationally recognized test agency. Double-wall Type B vent must be used to promote draft and to minimize condensation in the vent. No draft hood is required or offered. A single-acting the baro metric damper is required if the height exceeds 25 feet (7.6 m).
The connection from the appliance vent to the stack must be as direct as possible. The horizontal breaching of a vent must have an upward slope of not less than 1/4 inch per linear foot from the heater to the vent terminal. The horizontal portions of the vent shall also be supported for the design and weight of the material employed to maintain clearances and to prevent physical damage or separation of joints.

Termination
The vent terminal should be vertical and should terminate outside the building at least 2 ft (0.6 m) above the highest point of the roof that is within 8 ft (2.4 m). The vent cap should have a minimum clearance of 4 ft (1.2 m) horizontally from and in no case above or below electric meters, gas meters, regulators and relief equipment, unless a 4 ft (1.2 m) horizontal distance is maintained. The distance of the vent terminal from adjacent public walkways, adjacent buildings, open windows and building openings must be consistent with the NFGC (U.S.) or B149 (Canada). Gas vents supported only by flashing and extended above the roof more than 5 ft (1.5 m) should be securely guyed or braced to withstand snow and wind loads.
For factory approved vent termination caps, refer to the Illustrated Parts List (IPL) section of this manual. See page 65.

CAUTION: A listed vent cap terminal adequately sized, must be used to evacuate the flue products from the building.

Vent lengths are based on a lateral length of 2 ft (0.6 m). Refer to the latest edition of the NFGC for further details. When vertical height exceeds 25 ft (7.6 m), consult factory prior to installation.
*Subtract 12 ft (3.6 m) per elbow.

Horizontal Through-the-Wall Venting (Category III)

Installation
These installations utilize the heater’s internal blower to vent the combustion products to the outdoors. Combustion air is taken from inside the room and the vent is installed horizontally through the wall to the outdoors. Adequate combustion and ventilation air must be supplied to the equipment room in accordance with the NFGC (U.S.) or B149 (Canada). The total length of the horizontal through-the-wall flue system should not exceed 75 equivalent ft (22.86 m) in length. the horizontal run exceeds 75 equivalent ft (22.86 m), an appropriately-sized variable-speed extractor must be used. Each elbow used is equal to 12 ft (3.6 m) of straight pipe. The vent cap is not considered in the overall length of the venting system. The vent must be installed to prevent flue gas leakage. Care must be taken during assembly to ensure that all joints are sealed properly and are airtight. The vent must be installed to prevent the potential accumulation of condensate in the vent pipes. It is recommended that the vent be insulated. Insulation is required for installations in cold environments (i.e. below 40°F or 4°C). It is required that: The vent must be installed with a condensate drain located in proximity to the heater as directed by the vent manufacturer. The vent must be installed with a slight upward slope of not less than 1/4 inch per foot of horizontal run to the vent terminal.

Termination
The vent cap MUST be mounted on the exterior of the building. The vent cap cannot be installed in a well or below grade. It must be installed at least 12″ (305 mm) above ground level and above normal snow levels. The vent terminal must be located NO CLOSER than 12″ (305 mm) off the wall.
For factory approved vent termination caps, refer to the Illustrated Parts List (IPL) section of this manual. See page 65.

CAUTION: This venting system requires the installation of a condensate drain in the vent piping per the vent manufacturer’s instructions. Failure to install a condensate drain in the venting system will cause damage which will not be covered unde the warranty.

WARNING: No substitutions of flue pipe or vent cap material are allowed. Such substitutions would jeopardize the safety and health of inhabitants.

Direct Vent – Horizontal Through-the-Wall
Installation
These installations utilize the heater’s internal blower to draw combustion air from out doors and vent combustion products to the outdoors, see Table K.

NOTE: Use of B-vent on such a system does not meet direct-vent requirements.

The exhaust and intake systems must be installed to prevent the potential accumulation of condensate. It is recommended that they be insulated. Insulation is required for installations in cold environments (i.e. below 40°F (4°C).

The flue termination cap is not considered in the overall length of the venting system.

Table K. Category III Horizontal Vent & Horizontal Direct Vent

• Subtract 12 ft (3.6 m) per elbow.
  ** Schedule 40 in PVC or CPVC.
  Care must be taken during assembly y that all joints ar sealed properly and are airtight.
  The vent must be installed to prevent the potential cumulation of condensate in the vent pipes. It is rec om mended that the vent be insulated. Insulation is required for installations in cold environments (i.e., below40°F or 4°C).
  For installations in extremely cold climates, it is required that:

  1. The vent must be installed with a slight upward slope of not more than 1/4 inch per foot of horizontal run to the vent terminal. An approved condensate trap must be installed per applicable codes.
  2. The air intake vent must be insulated through the length of the horizontal run.

Termination
The exhaust vent cap MUST be mounted on the exterior of the building, and cannot be installed in a well or below grade. It must be installed at least 12″ (305 mm) above ground level and above normal snow levels. The exhaust vent cap MUST NOT be installed below or closer than 3 ft (0.9 m) from the air intake. Venting any closer to the air intake will cause combustion gases to recirculate into the heater.
This type of installation can cause non-warrantable problems with components and poor operation of the heater due to the recirculation of flue products. Multiple vent caps should be installed in the same horizontal plane with a 4 ft (1.2 m) minimum clearance from the side of one vent cap to the side of the adjacent vent cap(s). See Figure 11. Combustion air supplied from outdoors must be free of particulate and chemical contaminants. To avoid a blocked flue condition, keep the vent cap clear of snow, ice, leaves,
debris, etc.

Use only the special gas vent pipes listed for use with Category III gas burning heaters, such as the AL294C stainless steel vents offered by DuraVent (www.duravent.com). Follow the vent manufacturer’s installation instructions carefully.

WARNING: No substitutions of flue pipe or vent cap material are allowed. Such substitutions would jeopardize the safety and health of inhabitants.
CAUTION: Condensate is acidic and highly corrosive.

Direct Vent—Vertical
Installation
These installations utilize the heater-mounted blower to draw combustion air from outdoors and force the heated flue products through the vent pipe under positive pressure.
The vent material must be in accordance with the above instructions for vent materials. Vent material must be listed by a nationally recognized test agency.
The connection from the appliance flue to the stack must be as direct as possible and should be the same size or larger than the vent outlet.
It is recommended that the intake vent be insulated in colder climates.

NOTE: Use of B-vent on such a system does not meet direct-vent requirements.

Termination
The flue should be vertical and should terminate outside the building at least 2 ft (0.6 m) above the highest point of the roof within 10 ft (3.0 m). The vent cap should have a minimum clearance of 4 ft (1.2 m) horizontally from and in no case above or below (unless a 4 ft (1.2 m)) horizontal distance is maintained) electric meters, gas meters, regulators and relief equipment. The distance of the vent terminal from adjacent public walkways, adjacent buildings, open windows and building openings must be consistent with the NFGC (U.S.) or B149 (Canada).
Vent pipes supported only by flashing and extended above the roof more than 5 ft (1.5 m) should be securely guyed or braced to withstand snow and wind loads. The air inlet opening MUST be installed 1 ft (305 mm) above the roof line or above normal snow levels that might obstruct combustion air flow. This dimension is critical to the correct operation of the heater and venting system and reduces the chance of blockage from snow. The vent cap must have a minimum 3 ft (0.9 m) vertical clearance from the air inlet opening.
Use only the special gas vent pipes listed for use with Category III gas burning heaters, such as the AL29-4C stainless steel vents offered by DuraVent (www.duravent.com). Pipe joints must be positively sealed. Follow the vent manufacturer’s installation instructions carefully.

WARNING: No substitutions of vent pipe or vent cap material are allowed. Such substitutions would jeopardize the safety and health of inhabitants.

Outdoor Installation

The vent cap provided with the heater is the standard venting method for outdoor installations. Care must be taken when locating the heater outdoors because the flue gases discharged from the vent cap can condense as they leave the cap. Improper location can result in damage to adjacent structures or building finishes. For maximum efficiency and safety, the following precautions must be observed:

1. Periodically checthe venting system. The heater’s venting areas must never be obstructed in any way and minimum clearances must be observed to prevent restriction of combustion and ventilation air. Keep area clear and free of combustible and flammable materials.
2. Do not locate adjacent to any window, door, walkway, or gravity air intake. The vent must be located a minimum of 4 ft (1.2 m) horizontally from such areas.
3. Install above grade level and above normal snow levels.
4. Vent terminal must be at least 3 ft (0.9 m) above any forced air inlet located within 10 ft (3.0 m).
5. Adjacent brick or masonry surfaces must be protected with a rust-resistant sheet metal plate.

NOTE: Condensate can freeze on the vent cap. Frozen condensate on the vent cap can result in a blocked flue condition.

Gas Supply Connections

Gas piping must have a sediment trap ahead of the heater gas controls, and a manual shutoff valve located outside the heater jacket. All gas piping should be tested after installation in accordance with local codes.

CAUTION: The heater and its manual shutoff valve must be disconnected from the gas supply during any pressure testing of that system at test pressures in excess of 1/2 psi (3.45 kPa). Dissipate test pressure in the gas supply line before reconnecting the heater and its manual shutoff valve to gas supply line. FAILURE TO FOLLOW THIS PROCEDURE MAY DAMAGE THE GAS VALVE. OVER- PRESSURIZED GAS VALVES ARE NOT COVERED BY A WARRANTY. The heater and its gas connections shall be leak-tested before placing the appliance in operation. Use soapy water for leak test. DO NOT use an open flame.

Supply Pressure
CAUTION: Do not use Teflon tape on gas line pipe thread. Only sealant tape or a pipe compound rated for use with natural and propane gases is recommended. Apply sparingly only on male pipe ends, leaving the two end threads bare.

A minimum of 4 in. WC and a maximum of 10.5 in. WC  upstream pressure under load and no-load con editions must be provided for natural gas. Required pressure for Propane Gas: Min = 8.0″ WC (Dynamic), Max = 13″ WC (Static).

Gas Pressure Regulator
The gas manifold pressure is preset to a negative -0.30″ WC. If an adjustment is needed, remove the gas valve throttle seal and turn the adjustment screw clockwise to increase pressure or counter-clockwise to decrease pressure. If available, the O2 must be within 4.5 – 5.5% using a calibrated combustion analyzer.

Table N. Heat Exchanger Pressure Drops
NOTE: Table capacity is based on 2″ Schedule 40 piping.
High-temperature CPVC header flanges and header flange nuts are provided. If there is any possibility of backsi phoning when the pump stops, it is highly recom men dedthat a check valve (or valves) also be installed in the system. It is also recommended to have a downstream ball or gate valve to regulate heater flow and pressure. Before attaching the 2-inch unions to the inlet/Out header, make sure the O-rings are properly seated in the grooves. Use Aqualube or equivalent non-petroleum-based lubri canton the O-ring. Hand tighten the unions. Glue PVC piping directly to the unions. ProTek Shield Assembly
This heater is equipped with a ProTek Shield Assembly located horizontally on the right side of the Inlet water connection.
This component provides protection to the heat exchanger against galvanic corrosion when properly bonded to the heat exchanger. It should be replaced when the weight of
the ProTek Shield is reduced to about 40% of the original weight (1.46 lbs.).

CAUTION: STOP the pool pump before attempting to remove ProTek Shield Assembly. Failure to do so may result in damage to ProTek Shield Assy, loss of pool water, or personal injury.

CAUTION: Do not use tools to remove (twist) the ProTek Shield Assy or the wing nut on the stud of the ProTek Shield Assy. Non-warrantable damage may occur.

Follow the steps below to replace the ProTek Shield Assy:

1. Shut off the pool pump and bleed pressure from the system.
2. Close isolation valves to minimize pool/spa water loss.
3. Remove wing nut from bottom stud on ProTek Shield Assy.
4. Remove bonding wire ring terminal frothe stud.
5. Rotate ProTek Shield Assy counter-clockwise (by hand) to unscrew it from the assembly.
6. Inspect/replace as necessary and reverse the above procedure to reinstall. Hand tightens only! Do not use tools.

NOTE: Make sure the O-ring is properly seated in the O-ring groove before installation.
Unitherm Governor Operation
CAUTION: The patented Unitherm Governor is a thermostatic mixing valve specifically designed to maintain n constant heater internal temperature between 120°F (49°C) and 135°F (57°C) despite continually changing flow rates from the filter and changing pool temperatures. This range is needed to reduce the amount of condensation from the fin tubes which will occur if the heater runs for any length of time below 100°F (38°C) water from the pool. It is also needed to inhibit scale formation in the tubes by maintaining temperatures well below accelerated scaling temperatures. Internal Automatic Bypass Valve
In addition to the Unitherm Governor, a built-in auto maticbypass valve is provided in the In/Out header. While the Unitherm Governor responds to the changes in water temperature in the heater, the internal bypass valve automatically responds to changes in water pressure in the piping system. The proper amount of water flow is mainta in through the heater under varying pressures dictated by the conditions of the pump and filter.

External Auxiliary Bypass Valve
Where Required – An auxiliary bypass valve should be used when flow rates exceed 100 GPM (379 lpm). Usually,ly a high-performance pump size larger than two horsepower will exceed this flow rate. This valve is required to complement the function of the automatic bypass valve, particularly when starting the heater in winter or early spring when the spa or pool temperature is below 50°F (10°C). It also serves to eliminate needless pressure drops through the heater and accompanying reduction in the flow rate to the spa jets.

Auxiliary Bypass Valve Adjustment
To set bypass – With a clean filter, adjustment is made by feeling the inlet and outlet pipes at the heater. Outlet pipes should be slightly warmer than inlets and comfortable to the touch. If the pipe is hot, close the bypass; if cold, opethe bypass.
Pressure Relief Valve Installation
A 3/4″ NPT connection is provided in the header to the installation of a pressure relief valve (PRV). The valve shall be installed in a vertical position. The PRV can leak over time and may not operate correctly if installed in a different orientation. Do not over-tighten. Install pressure relief valve hand-tight, plus a 1/2 turn. Use the PRV kit (018936F) and Figure 23 below to properly plumb the PRV.

NOTE: To avoid water damage or scalding due to valve operation, the drain pipe must be connected to the outlet of the PRV and run to a safe place of discharge. The drain pipe must be the same size as the valve discharge connection throughout its entire length and must pitch downward from the valve. No shutoff valve shall be installed between the relief valve and the drain line. The valve levers should be tripped at least once a year to ensure that waterways are clear.
The heater requires water flow and positive pressure to fire and operate properly. It must therefore be installed downstream of the discharge side of the filter pump. See
Figure 24 and Figure 25.
A typical installation is plumbed as follows:

1. The inlet side of the filter is plumbed directly to the discharge side of the filter pump;
2. The outlet side of the filter is then plumbed to the inlet of the heater; and
3. The outlet of the heater is plumbed to the return line to the pool or spa. The pump, filter, and heater are thus plumbed in series (Salt generators and chemical feeders must be downstream of the pool heater).

CAUTION: An additional source of heated water, e.g. a solar heating system, must be connected to the main line ahead of the heater inlet pipe in order for it to act as the primary heat source. If the primary system provides adequate heat to maintain the setpoint, the heater will not fire. Be advised that the control panel will then display sensed water temperatures downstream of the primary heating system, rather than the temperature of the water exiting the pool.
Heater must be located so that any water leaks will not damage the structure the adjacent area. CPVC or PVC pipe may be glued directly into the half-unions provided.

ELECTRICAL WIRING

NOTE: If it is necessary to replace any of the original wirings, use 150°C wire or its equivalent.
WARNING: The heaters are factory-wired for 240 VAC, 1Ph, 60Hz power supply. DO NOT attempt to operate at 208 VAC or below.
NOTE: Holes not utilized on jacket and control box can be used for fireman switch or auxiliary control interface.

Electrical Power Draw
CAUTION: A bonded lug is located below the junction box. Failure to ground the heater electrically could affect the heater’s electronics.
NOTE: See “Time Clock/Fireman’s Switch” on page 38 for further instructions if using a time clock/ fireman’s switch.
The Electronic Ignition Device automatically lights the burner upon a call for heat. The heater is supplied with a dual-voltage transformer for 120 VAC or 240 VAC input power hookup. When operating on 120 VAC power, units draw 1.6 amps. When operating on 240 VAC power, units draw 1.2 amps.

Transformer Wiring
120 VAC Wiring
For 120 VAC input power to the unit, connect the field supplied Black wire (L1) to the (2) Black wires from the heater. Connect the white and red/white wires to the “N” or Neutral leg of the power supply. There should be no connection to the red wire for 120 VAC operation. Attach a wire nut to the red wire.

CAUTION: The heater is prewired with a 240V connector to the blower. If the supply voltage is 120V, replace the connector with the supplied 120V (red connector). Using the wrong corresponding connector will cause electrical damage.
240 VAC Wiring
For 240 VAC input power to the unit, connect the black wires to the L1 or hot leg of the power supply. Connect the red and red/white wires to the “L2” or second hot leg of the power supply. There should be no connection to the white wire for 240 VAC operation. Attach a wire nut to the white wire.
WARNING: DO NOT attempt to operate the heater at 208 VAC.

The heater must be electrically grounded and bonded in accordance with local codes, or, in the absence of local codes, with the latest edition of the National Electrical Code, ANSI/NFPA 70. (Canada – Canadian Electrical Code, CSA C22.1, Part 1 and Part 2.)
CAUTION: If the transformer’s primary side is wired for 120 VAC and 240 VAC is applied, damage to the transformer and PC board may result. Such damages are not covered under many facturer limited warranties.
NOTE: Input power to the heater (120 or 240 VAC) can be supplied from the load (pump) side of the time clock or directly from the GFCI power source. It is preferred that full-time power be supplied to the heater from the GFCI power source and that the heater be controlled by the fireman’s switch connection or using a two or three-wire remote. If using a switched GFCI power source, the heater could display false service indicators on the display panel if the pump is turned off.

WARNING The ability to properly perform service on this equipment requires certain expertise, mechanical skills, tools, and equipment. If you do not possess these, do not attempt to perform any service on this equipment other than those procedures recommended in this Manual.
Remote-Wired Control Installation and Operation
CAUTION: Before installing remote controls to the heaters, read the following: The Heater is remote-ready. The digital display shows the actual pool temperature, operating status, and service messages. See Figure 54. The touch keys on the control panel allow you to select the desired pool or spa temperature. It also indicates when a remote system is controlling the heater by displaying Remote in the display. When connecting the heater to a remote system, identify whether it is a two- or three-wire remote system. Select the appropriate instruction listed below to properly install the remote to the heater.
Remote-Wired Operation Selector
The heaters are equipped with the ability to work with external remote controls. The supplied 3-pin remote wiring connector supplies power out to either a toggle switch or the switch contacts of a third-party remote. The remote works by either making or breaking the circuit created by the remote wiring. Typically, a remote does not supply power to the heater, it only provides a switching function to turn the heater On or Off. If your remote is supplying its own voltage to the heater, it will not work with this heater and may damage the digital circuit board.
For the operation of the heater using the onboard thermostatic controls with a time clock see “Time Clock/Fireman’s Switch” section on page 38.

Activating the Remote
To activate or deactivate the remote function, press and hold the UP and DOWN arrow keys for 3 to 5 seconds. The second line of the display will alternate even when the unit is off (“No Demand”).
NOTE: When in remote operation, the keypad mode and temp buttons are disabled.

Remote Control Wiring
ATTENTION
OBSERVE PRECAUTIONS ELECTROSTATIC
SENSITIVE DEVICES
CAUTION: Electrostatic Discharge (ESD) damage can be caused by direct or indirect contact with the wiring or circuit board. When one walks to the heater area, an electrostatic charge accumulates on the body. Contact of a finger allows the body to discharge, possibly causing device damage. This damage can be limited if the service person discharges himself, following ESD preventive/removal practices, and holds on to the heater enclosure for 5-seconds before proceeding.
Important Installation Notes for Remote or External Wiring Configuration:

• Remote wiring must be run in a separate conduit.
• Remote wiring must not be run parallel to high voltage lines.
• For runs of under 30′ (9 m), remote wiring should have stranded conductors with a minimum of 22 AWG, 600V, cable twisting 1.5″ to 2.5″ (3.8 to 6.4 cm) lay and jacketed.
• For runs over 30′ (9 m), the conductors should be a minimum of 20 AWG, 600V, cable twisting 1.5″ to 2.5″ (3.8 to 6.4 cm) lay that is shielded and jacketed.
• The maximum cable length is 200′ (61 m).
• For both two- and three-wire remote systems, the provided 3-pin wiring connector must be utilized.

NOTE: The remote wires must be connected to the 3-pin connector before the connector is plugged into the board.
2-Wire Remote Control (On-Off)
This application assumes that only one heating function (pool or spa) is required.

1. Turn on the power to the heater.

2. For a 2-Wire Remote Control from a remote without its own sensor, push the MODE key to the “POOL” or “SPA” mode and set the desired setpoint (e.g.102°F (39°C) for Spa).

3. For a 2-Wire Remote Control from a remote with its own sensor, push the MODE key to select “POOL” or “SPA” mode and set the temperature to the highest setting available on the control. The actual setpoint will be controlled by the remote control.

4. Turn the MODE button to “OFF” and remove power from the heater.

5. On the “Remote Interface Harness”, connect the BLUE wire to one side of the “REMOTE” switch and connect the other side to either the ORANGE/BLACK
   wire for “SPA” operation or the BLACK/ORANGE wire for “POOL” operation. See Figure 57.

6. Attach wire nut on the unused wire to the “Remote Interface Harness.”

7. Install the “3-wire Remote Control Harness” to the P8 connector and turn power “ON” to the heater. See  Figure 57.
   

3-Wire Remote Control Using ThreePosition Switch (Pool-Off-Spa, or Low- OffHigh)
This application assumes that both heating functions (pool and spa) are required.

1. Turn on the power to the heater.

2. Push the MODE key to the “POOL” or “SPA” mode and set the desired temperature for each (e.g. 80°F (27°C) for the Pool and 102°F (39°C) for Spa).

3. Turn the MODE key to “OFF” and remove power from the heater.

4. On the “Remote Interface Harness” connect the BLUE wire to one side of the “REMOTE” switch and connect the ORANGE/BLACK wire for the “SPA” operation and
   the BLACK/ORANGE wire for the “POOL” operation. See Figure 57.

5. Install the “Remote Interface Harness” to the P8 connector and turn power ON to the heater. See Figure 58.
   For activation of the remote control, see “Activating the Remote” on page 36.

Time Clock/Fireman’s Switch
To operate the heater with a time clock, connect the timer to the clock/fireman’s switch connection in the heater’s wiring.
The time clock should be of the dual-switch type and set to “shut off the call for heat” to the pool heater 15 to 20 minutes prior to shutting down the pool pump. The fireman’s switch connection is located at the power junction box. Splice into the Purple wire jumper tagged “Where necessary” and add “Fireman’s switch circuit here” to connect the time clock. See Figure 59.
The fireman’s switch connection must be a dry contact and must not supply power to the heater. Powering the fireman’s switch connection externally may damage the heater, and is not covered by warranty.  Do not exceed 50′ (15 m) of total wiring using 18 AWG stranded copper wire rated for 221°F (105°C) minimum.
NOTE: When using a time clock, the heater will display “Clock/Fireman Sw” when the fireman’s switch is open, indicating that the time clock has shut off the call for heat.

Water Pressure Switch
The water pressure switch ensures that the heater operates only when the filter pump is in operation. It is located on the In/Out header. It is factory-set at 1.75 PSI for deck level installation.
Water Pressure Switch Adjustment
When the heater is located below the level of the spa or pool, it may be necessary to adjust the pressure switch to compensate for the no-flow static head. If it is necessary to adjust the water pressure switch, do the following:

1. Make sure the pool filter is clean before adjusting the switch.
2. Set the heater control to the OFF mode.
3. Turn the filter pump ON and confirm that the pressure switch is closed (use a multimeter to check). If the pressure switch fails to close, either the switch setting is too high or not enough pressure is being supplied by the filter pump.
4. Turn the heater ON.
5. Manually turn the pressure adjustment knob clockwise until the heater shuts off. (A flat screwdriver may be necessary the knob is too tight.)
6. Slowly turn the adjustment knob counter-clockwise until the heater calls for heat again.
7. Turn an additional 1/2 turn counterclockwise.
8. While the heater is running, check the adjustment by turning the pump off and on several times. The burners should shut off immediately when the pump is turned off. If it does not, repeat the above steps until the proper operation is observed.

NOTE: The sheet metal access panels should be in place at all times to protect the water pressure switch from rain and other environmental factors.

NOTE: If the heater is installed outside of the limits shown, a higher- pressure rated (11 psi / 76 kPa) switch may be used. A flow switch, mounted and wired adjacent to the heater, may be used in place of the factory-mounted pressure switch. See “Illustrated Parts List” on page 65 for 11 psi / 76 kPa water pressure switch.
Two-Speed Pumps
In some cases, the flow on the low-speed is insufficient to operate the heater. This is apparent when the water pressure switch cannot be further adjusted or if the heater makes banging noises or shuts off on high limits. In these cases, the pump must be run at high speed when heating the water.
CAUTION: Do not operate the heater without the function of a properly- adjusted water pressure switch or flow switch.
Cabinet Limit Switch
Heaters are equipped with a cabinet limit switch to prevent overheating of the components inside the cabinet in case of any flue gas leakage from the combustion chamber. Itis a “manual-reset” type switch that must be reset by the service technician after making sure any leaks or damage to the unit has been fixed. High Limits
The heater is equipped with two high limits, both are automatic and are located in the inlet/outlet header. Although both limits are preset to auto- reset, the control board will request the operator to press “mode” if either limit is tripped while the heater is running.
NOTE: An erratic high limit is often characteristic of an internal heat exchanger problem, e.g. scale build-up, or defective bypass. Refer to “Troubleshooting” on page 46.

High Limit Removal

1. Shut off the main electrical power switch to the heater.
2. Remove inlet/outlet sheet metal access panel.
3. Remove defective high limit and replace with the correct, new high limit.
4. Replace the access panel.

Adjusting Valve Manifold Pressure

1. Remove the cap to gain access to the adjustment screw.
2. Turn the adjustment screw clockwise to increase pressure. (For example, at -0.6″ WC turning clockwise will increase the pressure to -0.5″ WC,-0.4″ WC, etc.)
3. The manifold pressure should be negative -0.30 “WC (+/- 0.20 “WC) while running. If a combustion analyzer is available, the O2 reading should be between 4.5 – 5.5% O2 while running.
4. Install the cap before reading the manifold pressure.

Orifice Removal

1. Locate and close the external manual shutoff valve.
2.  Loosen the external gas union.
3. Locate and remove jacket top.
4. Locate and remove the four (4) bolts & nuts holding the gas orifice in place. See Figure 65.
5. Carefully remove the gas orifice and do not misplace the O-rings attached to the flanges.
6. Inspect and/or replace the orifice with the correct size.
   

Gas and Orifice Selection
The gas orifice and the air orifice MUST match to attain the correct air/fuel ratio. The orifices are matched when the number of pockets on the side of the gas orifice is the same as the number of notches on the edge of the air orifice. The orifice selection is based on elevation, not on the fuel used. See Table R.
The gas orifice is located on the gas train, between the gas valve and the combustion blower. The air orifice is located on the inlet side of the combustion blower.
NOTE: Gas orifices for propane gas have a black oxide finish.

10. Lift the heat exchanger and remove it from the unit.

Tube Cleaning Procedure
Establish a regular inspection schedule, the frequency depending on the local water conditions and the severity of service. Do not let the tubes clog up solidly. Clean out deposits over 1/16″ (1.6 mm) in thickness.
The heater may be cleaned from the return header side, without breaking pipe connections. It is preferable, however, to remove both headers for better visibility through the tubes and to be sure the ground-up lime dust does not get into the system.
After reaming, mount the wire brush in place of the auger and clean out debris remaining in the tubes.
Another method is to remove the heat exchanger, ream tubes and immerse heat exchanger in non-inhibited de-scale solvent for severe scale build-up.

Decorating Procedure
WARNING: Soot Is Combustible. Exercise Extreme Care.
Soot will clog areas between fins and cause eventual tube failure. Any sign of soot at the base of the burners or around the outer jacket indicates a need for cleaning.

1. Follow the heat exchanger removal process as shown in the “Heat Exchanger Removal” section.
2. The heat exchanger has a baffle on the sides, or the bottom, depending on the model size, which has to be removed.
3. Remove the heat exchanger from the unit and wash with a garden hose, making sure soot is removed from the spaces between the fins.
4. Reverse the heat exchanger removal procedure to reinstall.

NOTE: In extreme cases, it may be necessary to do steam cleaning at the local car wash. DO NOT WIRE
BRUSH.
Heat Exchanger Reinstall
It is highly recommended to replace the top combustion chamber with the refractory during the heat exchanger installation process. Failing to do so can result in damage to the heater and potentially dangerous operating conditions. See Figure 70.

Unitherm Governor (U.G.) Replacement

1. Shut off water, gas, and electricity, close valves, and relieve pressure.
2. Drain heat exchanger.
3. Remove the retainer plug located next to the outlet pipe connection.
4. Unsnap old U.G. to remove from retainer plug. Snap-in new U.G.
5. Reinstall retainer plug, taking care to lubricate gasket with a non-petroleum based grease such as

Figure 71. Unitherm Governor
To test the operation of the Unitherm Governor, place in hot water over 120°F (49°C), and watch for the movement against spring. If there is no movement, replace the UG.
WARNING: When removing the burners or heat exchangers, take precautions to avoid creating airborne dust and avoid inhaling airborne fibers. When cleaning spills, use wet sweeping or High-Efficiency Particulate Air (HEPA) filtered vacuum to minimize airborne dust. Use feasible engineering controls such as local exhaust ventilation or dust collecting systems to minimize airborne dust. Wear appropriate personal protective equipment including gloves, safety glasses with side shields, and appropriate NIOSH-certified respiratory protection, to avoid inhalation of airborne dust and airborne fiber particles.

OPERATING INSTRUCTIONS

Before Start-Up
Burners
Kee the heater area clear and free from combustibles, flammable liquids and chemicals. Do not obstruct the flow of combustion and ventilation air.
Water must be flowing through the heater during operation. Ensure that the system is filled with water and that the pump is operating. The heater should always have a minimum of 40 GPM (151 lpm) water flowing through it.
Start-Up Procedures
Your pool/spa heater has been designed for years of safe and reliable pool/spa water heating. It is available with electronic ignition only. This manual provides installation, the operation, maintenance, and service information for these heaters.

If your heater has been installed correctly, operating the heater is an easy task. The upper front panel of the heater contains the control center that allows you to turn the heater On or Off and adjust the temperature settings for the pool or spa. The temperature range is factory-set from 65°F (18°C) to 104°F (40°C). See Figure 72 for the location of the toggle switch to turn the heater On and Off. See the “Controls” section on page 27 for additional details about the use of the controls in the Control Adjustments subsection.
After Start-Up
Feel the inlet and outlet pipes. The outlet pipe should be only slightly warmer than the inlet. It should not be hot.
WARNING: Should overheating occur or the gas supply fail to shut off, turn off the manual gas control to the appliance.
Water Pressure Switch
A water pressure switch is provided in the heater to shut off the burners in the event that water supply is interrupted. It is very important to verify that the switch electrically opens and shuts off the gas valve when water flow to the heater is interrupted. Otherwise, rapid and severe damage will likely occur to the heater.
The water pressure switch should be checked and adjusted for proper operation by a qualified service person at the time of installation and periodically checked thereafter. Refer to “Water Pressure Switch Adjustment” on page 38.

WARNING: Operation of the heater without water circulation will cause rapid and severe damage to the heater, which will not be covered under the warranty.

1. Inspect and operate all controls, gas valve and pressure relief valve (if equipped).

2. On indoor heaters, clean room intake openings to ensure adequate flow of combustion and ventilation air.
   CAUTION: Combustion air must not be contaminated by corrosive chemical fumes which can damage the heater. Such damage will not be covered under warranty.

3. Keep the area around the heater clear and free from combustible materials, gasoline and other flammable and corrosive vapors and liquids.

If Heater Will Not Fire: If you have no electrical power, it may be that your “circuit breaker” has tripped. Try resetting it.
If you have electrical power but the heater will not fire check the following or see “Troubleshooting” on page 46:

1. The time clock must be in the ON position.
2. Your pump strainer basket may be full. If so, remove debris.
3. Your filter may be dirty. If so, backwash or clean the filter. (To tell if your filter is dirty, look to see if the filter pressure reading is higher than usual).
4. The pump may have lost its prime and be running dry. Check the pressure on the filter. If there is no pressure; then you are not moving water (or your gauge is broken). Try to get the pump to run at its normal flow rate.

Cold Weather Operation
Important Freeze Information
MODERATE CLIMATE: Heater operation can continue during short-term cold spells. When temperatures are between 0°F (-18°C) and 32°F (0°C), flow (continuous pump operation) must be maintained.
CAUTION: Do not use the heater to maintain water temperatures just above freezing or for freeze protection. When n heater is used during freezing weather, care must be taken to avoid freeze-ups. Continuous pump operation is a must. Additional protection may be required. The heater is not warranted against freeze-ups.
COLD CLIMATE: Prolonged operation with water temperatures below 50°F (10°C) is not recommended. When starting the heater with water temperatures below 50°F (10°C), operate the heater continuously until higher temperatures are reached. Operating the heater for prolonged periods with pool water below 50°F (10°C) can seriously damage the heater, and is not covered by the warranty. For cold climate areas, please follow the winterizing procedures listed below.
Winterizing the Pool and Spa Heater
Heaters installed outdoors in freezing climate areas may be shut down for the winter. Observe the following procedure for winterizing the heater:

1. Turn off gas valve, manual gas valve, and electrical supply to the heater.
2. On the water connection, close any isolation valve to isolate the heater. Remove the lower right access panel to reveal the right side of the Inlet/Outlet header. The drain will be located underneath the header. Loosen and remove the drain plug. See Figure 74.
