DANGER! NATURAL GAS AND LIQUEFIED PETROLEUM

MODELS SAFETY
Both propane and natural gas have odorants added to aid in detecting a gas leak. Some people may not physically be able to smell or recognize this odorants. If you are unsure or unfamiliar with the smell of propane or natural gas, ask the gas supplier. Other conditions, such as “odorants fade”, which causes the odorant to diminish in intensity, can also hide or camouflage a gas leak. Always check with commercial leak odorants or soapy water.

• Gas detectors are recommended in propane and natural gas applications and their installation should be in accor dance with the detector manufacturer’s recommendations and/or local laws, rules, regulations or customs.
• Water heaters utilizing propane gas are different from natural gas models. A natural gas water heater will not function safely on propane gas and vice versa.
• No attempt should ever be made to convert the water heater from natural gas to propane gas. To avoid possible equipment damage, personal injury or fire, do not connect the water heater to a fuel type not in accordance with the unit data plate; propane for propane units and natural gas for natural gas units. These units are not certified for any other fuel type.
• Propane water heaters should not be installed below grade (for example, in a basement) if such installation is prohibited by federal, state and/or local laws, rules, regulations or customs.
• Propane or propane gas must be used with great caution. It is heavier than air and will collect first in lower areas making it hard to detect at nose level.
• Before attempting to light the water heater, make sure to look and smell for gas leaks. Use a soapy solution to check all gas fittings and connections. Bubbling at a connection indicates a leak that must be corrected. When smelling to detect a gas leak, be sure to sniff near the floor also.
• It is recommended that more than one method, such as soapy solution, gas detectors, etc., be used to detect leaks in gas applications.

NOTICE: If a gas leak is present or suspected:

• DO NOT attempt to find the cause yourself.
• DO NOT try to light any appliance.
• DO NOT touch any electrical switch.
• DO NOT use any phone in your building.
• Leave the house immediately and make sure your family and pets leave also.
• Leave the doors open for ventilation and contact the gas supplier, a qualified service agency or the fire department.
• Stay away from the house(or building) until the service call has been made, the leak is corrected and a qualified agency has determined the area to be safe.
• Follow the steps listed under “WHAT TO DO IF YOU SMELL GAS” found on Page 8 of this manual.

WARINING

• The installation of gas piping must comply with local utility company requirements and/or in the absence of local codes, use the latest edition of National Fuel Gas Code(NFGC), ANSI Z223.1/NFPA 54.
• If inlet gas pressure is out of allowable range (8.0″w.c(2.0kPa)-13.0″w.c.(3.2kPa) for propane gas, a gas pressure regulator must be installed to maintain the allowable inlet gas pressure.
• Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the water heater.

CAUTIONS

• DO NOT attempt repair of electrical wiring, gas piping, burners, vent connectors, or other safety devices. Refer repairs to qualified service personnel.

• Make sure before installation that the gas type will use is the same type on the data plate.
• The water heater unit should be installed by professionals. Improper installation may cause failure or dangerous conditions such as gas leaking or explosion.
• Water heater cannot be installed in an UN-VENTED bathroom, bedroom, basement, living room, closet, outdoor, stairway or an exit area. If installed in an exit area, it must be at least 16.5ft or more way from the exit.
• Vent pipe should extend from the wall at least 2″. The terminal must be at least 1.64 ft away from obstruction, and must be well vented.
• Vent pipe should slope 3° downward, to avoid condensing water and protect from rain entering.
• Vent pipe should avoid direct, strong wind because the downdraft will cause malfunction.
• The unit should be installed far from any blockage, and with plenty of enough space for installation and maintenance. Adequate clearances for servicing must be provided.
• The unit should not be installed in the same room with a gas stove.
• When determining the floor clearance, a clearance of 6″ must be maintained between the vent pipe and combustible material. A side wall clearance of 6″and a top clearance of 12″ must be maintained.
• The vent pipe can be up 32ft in length with one elbow.
• The vent pipe should be installed with a flame retardant wall thimble. Owner must refer to vent manufacturer’s instructions and specifications.
• The power socket connecting the water heater should be grounded properly with a GFCI circuit protector.
• The water heater should not be located in an area where leakage of the heat exchanger or connections will result in damage to the area adjacent to it or to lower floors of the structure. When such areas cannot be avoided it is recommended that a suitable catch pan, adequately drained, must e installed under the water heater. The pan must not restrict combustion airflow.
• The water heater should be installed as close as practical to have termination to minimize vent length and the number of elbows required for venting.
• A gas fired water heater or any other appliance should not be installed in a space where liquids which give off flammable vapors are to be used or stored. Such liquids include gasoline, propane gas (butane or propane), paint or adhesives and their thinners, solvents or removers.
• The unit should be installed far from heat sources, flammable and dangerous materials. Because of natural air movement in a room or other enclosed space, flammable vapors can be carried some distance from where their liquids are being used or stored. The open flame of the water heater’s main burner can ignite these vapors causing an explosion or fire which may result in severe burns, death or property damage.
• Raising the water heater will reduce, BUT NOT eliminate the possibility of lighting the vapor of any flammable liquids which may be improperly stored or accidentally spilled.
• If the water heater is installed in a garage, it should be installed so that the direct ignition system and main burner are no less than 18 ” above the garage floor.
• Hot and cold water lines should be insulated to conserve water and energy.

WARNING
Combustible construction refers to adjacent walls and ceilings and should not be confused with combustible or flammable products and materials. Combustible and/or flammable products and materials should never be stored in the vicinity of this or any gas appliance.

Proper operation of the water heater requires air for combustion and ventilation. Provisions for combustion and ventilation air must comply with referenced codes and standards.

Combustion and Ventilation A:
A confined space is one having a volume of less than 50 cubic feet per 1,000 BTU/Hr of the aggregate input of all appliances within that space.
The air must be supplied through two permanent openings of equal area. One is to be located with 12″ above the floor and the other is to be located within 12″ below the ceiling.
The minimum net free area of each opening must not be less than one square inch per 1,000 BTU/Hr of the total input rating of all the appliance in the enclosure (but not less than 100 square inches), if each opening communicates with other unconfined areas inside the building.
Buildings of unusually tight construction shall have the combustion and ventilation air supplied from outdoors, or a freely ventilated attic or crawl space. If air is supplied from outdoors, directly or through vertical ducts, there must be two openings located as specified above and each must have a minimum net free area of not less than one square inch per 4,000 BTU/Hr of the total input rating of all the appliances in the enclosure.

If horizontal ducts are used to communicate with the outdoors, each opening must have a minimum net free area of not less than one square inch per 2,000 BTU/Hr of the total input rating of all the appliances in the enclosure. If ducts are used, the minimum dimensions of rectangular air ducts shall not be less than 4″.
NOTICE: If the water heater is installed in an unconfined space within a building of conventional frame, masonry or metal construction, infiltration air is normally adequate for proper combustion and ventilation. If the water heater is installed in a confined space, provisions for combustion and ventilation air must be made.

NOTICE: If the duct openings which supply combustion and ventilation air are to be covered with a protective screen or grill, the net free area (openings in the material) of the covering material must be used in determining the size of the openings. Protective screening for the openings MUST NOT be smaller than 1/4” to prevent clogging by lint or other debris.

Corrosive atmospheres
The air in beauty shops, dry cleaning establishments, photo processing labs, and storage areas for liquid and powdered bleaches or swimming pool chemicals often contain such halogenated hydrocarbons.
An air supply containing halogenated hydrocarbons may be safe to breathe, but when it passes through a gas flame corrosive elements are released that will shorten the life of any gas burning appliance.
Propellants from common spray cans or gas leaks from A/C and refrigeration equipment are highly corrosive after passing through a flame.
The water heater warranty is voided when failure of the heater is due to operation in a corrosive atmosphere.
NOTICE: The water heater should not be installed near any air supply containing halogenated hydrocarbons.

Check the unit
Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the type of gas supplied corresponds to the water heater requirements. Verify all included parts are present (Check details from In The Box at Page 32)

Water supply connections
Plumbing should be carried out by a qualified plumber in accordance with local codes. Use approved plumbing materials and tools only.
Install a check valve between the water heater and the water shut off valve.

To conserve energy and to prevent freezing, insulate both cold and hot water supply lines. DO NOT cover the drain valves. Install a shut off valve near the inlet of the water heater for service and draining purposes. Before connecting the water supply pipe to the water heater, open the shut off valve and clean out sand, debris, air, caulking material, etc inside the pipe. Connect to the water inlet, then check water flow. Close the shut off valve and clean the water filter.
If a water heater is installed in a close water supply system, such as one having a backflow preventer in the cold water supply line, means shall be provided to control thermal expansion. Contact the water supplier or local plumbing inspector on how to control this situation.
To ensure proper operation of the water heater, the following water pressure guidelines should be followed:

• Operation of the water heater requires the minimum water pressure of 14 PSI and a minimum water flow rate of 0.75 GPM.
• Additional water pressure is required for long pipe runs and outlet fitting(s) water pressure drops.
• To maintain proper performance, ensure sufficient water supply pressure. The Required Water Pressure= Min. Operating Water Pressure (14 PSI)+Pipe Pressure Loss +Faucet and Shower Pressure Loss + Safety Margin (more than 5 PSI)
• To supply hot water to upper floors, additional water pressure (0.44 PSI / FT) must be ensure.
• The measurement should be calculated by the distance between the water inlet of the water heater (ground level) to the hot water faucet (upper floor level).
• Well water systems should be set at a range of 50-60 PSI.
• When the water is supplied from a water supply tank, the height of the tank and the diameter of the pipes and their relation to water pressure, should be taken into consideration. Gravity water pressure is not recommended.

IMPORTANT: Do not apply heat to the HOT or COLD water connections. Any heat applied to the water supply fittings will permanently damage the internal components of the water heater.

IMPORTANT: Do not apply heat to the HOT or COLD water connections. Any heat applied to the water supply fittings will permanently damage the internal components of the water heater.

NOTICE: If the water flow resistance of a shower head is too high, the burner in the water heater will fail to ignite. Keep the shower head clean from debris that could cause additional pressure drop.

NOTICE: If using mixing valves on the outlet, choose one which prevents cold water pressure from overcoming hot water line pressure.
DO NOT use pipes with smaller diameters than the water supply connection of the water heater.
Be sure to connect the water inlet and the hot water outlet as shown on the water heater. If reversed, the water heater will not function.
Installation of unions or flexible copper connections are recommended on the HOT and COLD water lines, so that the water heater may disconnect easily for servicing if necessary.

In regards to the hot water outlet

• Connections between the water heater and point(s) of use should be as short and direct as possible.
• DO NOT use lead or non-approved plastic pipe.
• To conserve energy and minimize heat loss, insulation of hot water piping is recommended.

NOTICE: The flow rate of hot water many vary when more than two faucets
(appliances, fixtures, etc) are being used simultaneously.
NOTICE: The pipes MUST be completely drainable. If the hot water faucets are located at a point higher than the water heater, place a drain valve at the lowest point (see diagram to the left).

Relief Valve
A new pressure relief valve, complying with the Standard for relief Valves and Automatic Gas shut off Devices for hot water supply systems, ANSI Z21.22, must be installed at the hot water outlet connection of the water heater at the time of installation, local codes shall govern the installation of relief valves.

For safe operation of the water heater, must be sure that:

• The pressure rating of the relief valve must not exceed 150 PSI, the maximum working pressure of the water heater as marked on the rating plate.
• The BTU/Hr rating of the relief valve must equal or exceed the BTU/Hr input of the water heater as marked on its rating plate.
• No valve of any type should be installed between the relief valve and the water heater.
• Discharge from the relief valve should be piped to a suitable drain to eliminate potential water heater damage. Piping used should be of a type approved for the distribution of hot water.
• Hot and cold water lines should be insulated up to the water heater.
• The discharge line must be NO SMALLER than the outlet of the valve and must pitch downward to allow complete drainage (by gravity) of the relief valve and discharge line.
• The end of the discharge line should not be threaded or concealed and should be protected from freezing. No valve of any type, restriction or reducer coupling should be installed in discharge line.

NOTICE: The diagram below illustrates a pressure only relief valve. If local codes require a combination temperature and pressure relief valve be installed, an extension piece may be needed.
NOTICE: Manual operation of relief valves should be performed at least once a year. Turn off the electrical power and gas shut off valve. Lift and release lever on the relief valve and check the manual operation of the relief valve. You should take precaution to avoid contact with the hot water coming out of the relief valve and to prevent water damage.
NOTICE: If the relief valve on the system discharges periodically, this may be due to thermal expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on how to correct this situation. Do not plug the relief valve.

Gas Supply

WARNING:

• Do not attempt to convert this water heater for use with a different type of gas other than the type shown on the rating plate. Such conversion could result in hazardous operating conditions. Please have a professional connect the gas pipe.
• The manual gas appliance shut off valve must be installed at the gas connection of the water heater at the time of installation.
• The branch gas supply line to the water heater should be clean black steel pipe or other approved gas piping material. A ground joint union or ANSI design certified semi-rigid or flexible gas appliance connector should be installed in the gas line close to the water heater.
• The National Fuel Gas Code (NFGC) mandates a manual gas shut off valve, see (NFGC) for complete instructions.
• DO NOT use excessive force (over 31.5 ft lbs) in tightening the pipe, particularly if pipe compound is used, as the unit may be damaged.
• Compound used on the threaded joints of the gas piping must be of the type resistant to the action of propane gas. Use compound sparingly and use on male threads only.
• A sediment trap should be installed at the bottom of the gas line.
• The inlet gas pressure to the water heater must not exceed 14″ w.c for propane gas. For purposes of input adjustment, the minimum inlet gas pressure (with main burner on) is shown on the water heater rating plate. If high or low gas pressures are present, contact your gas supplier for correction.
• The appliance and its individual shut off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 PSI (3.5 kPa). The appliance must be isolated from the gas supply piping system by closing its individual manual shut off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSI(3.5kPa).
• The appliance must be isolated from the gas supply piping system by closing its individual manual shut off valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 PSI (3.5kPa).

Leak Testing

WARNING: Never use an open flame to test for gas leaks, as property damage, personal injury, or death could result.
The water heater and its gas connections must be leak tested at normal operating pressures before it is placed in operation.

• Turn on the gas shut-off valves(s) to the water heater.
• Use a commercial leak detector or soapy water solution to test for leaks at all connections and fittings. Bubbles indicate a gas leak that must be corrected.

All connections should also be leak tested after the water heater is placed in operation.

Installing The Water Heater

NOTICE: The National Fuel Gas Code (NFGC) mandates a manual gas shut off valve: See (NFGC) for complete instructions. Local codes or plumbing authority requirements may vary from the instructions or diagrams provided and take precedent over these instructions.

Installing The Water Heater

DANGER: Failure to install the vent adapter and properly vent the water heater to the outdoors as outlined in the venting section of this manual will result in unsafe operation of the water heater causing death, serious injury, explosion, or fire. To avoid the risk of fire. To avoid the risk of fire, explosion, or asphyxiation from carbon monoxide, NEVER operate the water heater unless it is properly vented and has adequate air supply for proper operation as outlined in the venting section of this manual.

WARNING: Use UL approved Category III stainless steel vent material only. No other vent material is permitted. Refer to page 18 for clearances to combustible material.

Venting

The installation of venting must comply with national codes, local codes, and the vent manufacturer’s instructions.
The water heater must be vented to the outdoors as described in these instructions. DO NOT connect this water heater to an existing vent or chimney, it must be vented separately from all other appliances.
All vent components (adapters, pipe, elbow, terminals, etc.) should be UL 1738 Certified stainless steel venting materials (e.g. AL29-4C).
The specified vent termination must be used. The termination should be a 90° elbow type with screen. (Refer to page 26-27).
Use a vent pipe with an anti-disconnection structure.
The use of a high temperature silicone (500°F/260°C) may be required to seal vent connections. To prevent accidental gas exhaust leakage, apply a 1/4″ wide bead approximately 1/4″ from the end and another bead against to joint side of the stop bead.
Follow vent manufacturer’s installation instructions.
The unit can be vented either horizontally or vertically.
Vent pipe runs must be adequately supported along both horizontal and vertical runs.
The maximum recommended unsupported span should be no more than 5 feet. Support isolation hanging bands should be used. DO NOT use wire (See diagram below).

Venting Through Closed Spaces
If the vent piping passes through a closed space, wrap the vent pipe with inflammable insulation material that is at least 3/4″ thick. DO NOT let the insulation material make contact with flammable materials. A minimum clearance of 6″ between the vent pipe and ceiling should be maintained. Follow local codes. For maintenance and inspection purposes, the following holes are required to be made:
TWO (2) inspection openings that allow access to venting. One (1) of these openings should be close to where the vent pipe enters the ceiling. The other opening should be near the vent termination.
A ventilation hole with a 16 sq. in opening should be made at least every 10 feet.
NOTICE: Vent pipes must be completely insulated with inflammable material when installed with inflammable material when installed in alcoves, closets, and garages and must not touch any flammable material.

Venting Lengths

Maximum vent length
Owner must refer to vent manufacturer’s instructions and specifications.

One(1)90° elbow is equivalent to 5 feet of straight pipe

The system will not operate if there is excessive restriction (pressure drop) in the venting system. A maximum of 32 feet of vent pipe may be used provided there is only one 90° elbow in the system. If additional elbows are required: two elbows can be used with 27 feet, and three elbows can be used with 22 feet of vent pipe. A 90°elbow is equivalent to 5 feet of straight pipe. A 45°elbow is equivalent to 2 feet 6″ of straight pipe.
The termination elbow does not count as an elbow when determining total vent lengths.
The vent must be installed with a slight downward slope of 1/4″ per feet of horizontal run toward the vent terminal (see diagram below). This ensures that any condensate formed during operation of the unit is evacuated from the appliance.
A 1/4″ per feet upward slope is acceptable when it is not possible to vent with a downward slope, however, a UL approved category III stainless steel condensate trap MUST be installed at the beginning of the horizontal run (see page 21 Typical Horizontal Termination with 1/4″ per feet upward slope or page 17 Standard Vertical Vent Termination for examples).

Minimum vent length
The venting may be as short as 12″ provided one vent termination is installed to the outdoors through a sidewall, one 90° elbow is included in the installation, and the wall thimble is installed.
NOTICE: Make sure that the seam of the vent pipe in horizontal runs is toward the top of the installation (see illustration below).

Draining the condensate
In certain conditions, installations in unconditioned space or having long horizontal or vertical runs may accumulate condensate.
Condensate is known to be acidic, refer to local state (provincial) or federal codes for proper handling methods.
In order to prevent condensate from draining back into the water heater, we recommend a condensate trap and drain to be installed in a horizontal vent section as close as practical to the water heater vent connection.
NOT following proper condensate procedures will void warranty.
