Risk of Fire – Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the water begins to flow. Do not smoke or use an open flame near the faucet at the time it is open.

FOR INSTALLATIONS IN THE STATE OF CALIFORNIA
California Law requires that residential water heaters must be braced, anchored or strapped to resist falling or horizontal displacement due to earthquake motions. For residential water heaters up to 52-gallon (197 L) capacity, a brochure with generic earthquake bracing instructions can be obtained from: Office of the State Architect, 400 P Street, Sacramento, CA 95814 or you may call 916-445-8100 or ask a water heater dealer. Applicable local codes shall always govern installation. For residential water heaters of a capacity greater than 52 gallons (197 L) consult the local building jurisdiction for acceptable bracing procedures.

WATER TEMPERATURE ADJUSTMENT
Safety, energy conservation and hot water capacity are factors to be considered when selecting the water temperature setting of the water heater. Water temperatures above 125°F can cause severe burns or death from scalding. The thermostat is adjusted to its lowest temperature position when shipped from factory for safety considerations. Be sure to read and follow the warnings outlined on the label pictured to the left. This label is also located on the front of the water heater.

DANGER

• Water temperature over 125°F can cause severe burns instantly or death from scalds.
• Temperature control settings usually approximate tap water temperature. However, factors could cause water temperature to exceed 160°F regardless of control settings.
• Children, disabled, and elderly are at highest risk of being scalded.
• See instruction manual before setting temperature at water heater.
• Feel water before bathing or showering.
• Temperature limiting valves are available, see manual.
  

Time/Temperature Relationship in Scalds

The chart shown above may be used as a guide in determining the proper water temperature for your home.

There is a Hot Water SCALD Potential if the water temperature thermostat is set too high. Households with small children, disabled or elderly persons may require a 120°F (49°C) or lower thermostat setting to prevent contact with HOT water.

OPERATING INSTRUCTIONS

Safety Control

For added safety, this water heater is equipped with a Flammable Vapor Ignition Resistance (FVIR) system. If flammable vapors (such as gasoline) are drawn into the water heater’s air supply, the FVIR system is designed to isolate these vapors and shut down the water heater should they reach the pilot light and burner
This water heater has a door thermistor installed. Do not attempt to disable or modify this feature in any way. Doing so can lead to fire, explosion, or excessive and abnormal production of carbon monoxide.

DO NOT try to light the water heater if flammable vapors are present; this could cause a fire or explosion. When the flammable vapors have been removed, contact a qualified service technician. Replacement of the water heater due to a flammable vapor shutdown is not covered under the warranty.

Lighting and Shutdown

FOR YOUR SAFETY READ BEFORE LIGHTING

WARNING : If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

A. This appliance has a pilot which must be lit by a piezo electric spark gas ignition system. When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion.
D. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water

LIGHTING INSTRUCTIONS

1. STOP! Read all safety warnings in the label above, before attempting to light the pilot.

2. Turn the gas control/temperature knob counterclockwise to the OFF POSITION.

3. Wait 10 minutes to clear any gas. Smell for gas all around the appliance area, including near the floor. If you then smell gas, STOP! Follow “B” instructions in the safety information above. If you don’t smell gas, go to the next step.

4. Turn the control knob clockwise to the PILOT POSITION, push the knob down, and hold in position. (The pilot valve opens and allows gas to flow into the pilot burner.) NOTE: If the gas pipe is full of air (new installation), it takes longer to purge the air through the pilot before the pilot will light.

5. Continue to hold the knob down, and depress the piezo igniter repeatedly, about once a second, to light the pilot flame. Hold the knob down, for about 30 seconds, or until the status indicator starts to blink.
   NOTE : The LED should blink once every 3 seconds while holding a pilot flame. If it turns solid and does not begin to blink, repeat steps 2 through

6. If the pilot flame fails to light after 3 attempts, turn the knob counterclockwise to the OFF POSITION, and call a qualified service technician.

7. Release the knob and turn it clockwise to the desired temperature setting, ON POSITION as shown in the illustration above. The HOT setting is approximately 120°F. The burner will come on if the water temperature is significantly below the temperature setpoint, and the LED will begin to blink every 3 seconds as the appliance heats the water.

TO TURN OFF GAS TO APPLIANCE

1. Turn the control knob counterclockwise to the OFF POSITION. The status light will stop blinking and the appliance will completely shut off.
2. Turn off the gas supply to the appliance.

Extended Shutdown Periods
If the water heater will not be in use for an extended period of time, the appliance’s gas and water should be turned off and the water heater drained to conserve energy and prevent a buildup of dangerous hydrogen gas.

The water heater and pipes should also be drained if they could be exposed to freezing temperatures. After a long shutdown period, the water heater’s operation and controls should be checked by a qualified service technician. Confirm that the water heater is completely filled before placing it in operation.

Temperature Control

Water temperature can be adjusted by turning the knob of the gas control/thermostat on the front of the water heater. Always read and understand safety instructions contained in the Use & Care Manual before adjusting the temperature setpoint. Note that the thermostat is adjusted to its lowest temperature position when shipped from factory for safety considerations.
NOTE : Refer to Water Temperature in Safety Information.
Safety and energy conservation should be considered when selecting the temperature setpoint of the water heater:

• The recommended setpoint for the water heater is 120°F (49°C), as water temperatures above 125°F can cause severe burns or death from scalding.
• Lower temperature setpoints increase energy savings.
• Higher temperature setpoints can increase the cleaning performance of dishwashers and washing machines, as well as killing bacteria.

Mixing Valves
If the water heater’s temperature is set above HOT (120°F/49°C), supplemental mixing valves are recommended to reduce point-of-use water temperature by mixing hot and cold water in branch water lines.
Contact a licensed plumber or local plumbing authority for additional information.
Vacation Setting “VAC” :
This setting is recommended when you will be away from the home for an extended period of time and hot water is not needed. The vacation setting will reduce the water temperature to 55ºF (13°C) to conserve energy.

About the Gas Control/Thermostat

All temperatures listed on the water heater’s gas control/thermostat are approximate.
Maximum water temperatures occur just after the water heater has completed a heating cycle. To determine the water temperature at point-of-use, open a hot water faucet and hold a thermometer under the stream of water.
Frequent, short uses of hot water can cause a phenomenon called stacking, when the temperature of the water at the top of the tank (closest to pipes delivering water to the home) exceeds the temperature at the bottom of the tank (where the gas control/ thermostat is located).
Before use, always test the water temperature with your hand, keeping in mind that hotter water increases the danger of scalding.

The gas control/thermostat is equipped with two safety shut-off devices:

• One is designed to shut off gas to the water heater’s burner if the pilot light goes out.
• The other is designed to shut off gas to the burner if the water heater exceeds normal temperatures.
  If one of these safety shut-off devices is activated, refer to Troubleshooting Tips,.

Should overheating occur or the gas supply fails to shut off, turn off the manual gas control valve to the appliance. Turn off gas to the water heater if it has been subjected to overheating, fire, flood or physical damage. (Refer to Lighting and Shutdown, page 7.) Do not operate the water heater again until it has been thoroughly checked by a qualified service technician. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

CARE AND CLEANING

Exterior Surfaces
Hand wash with a damp cloth, using only warm water. Wipe dry using a dry, clean cloth.

Preventive Maintenance

For years of dependable service, the following annual maintenance program is recommended:

1. Test the Temperature and Pressure Relief Valve.
2. Drain and Flush the Water Heater Tank.
3. Inspect the Anode Rod.
4. Inspect the Gas Control/Thermostat.
5. Inspect the Pilot Light and Burner.
6. Inspect Water and Gas Systems.
   NOTE : It is recommended that you call a service technician to perform these tasks.

Temperature and Pressure Relief Valve

Risk of Scald – Before manually operating the relief valve, make certain no one will be exposed to the danger of coming in contact with the hot water released by the valve. The water may be hot enough to create a scald hazard. The water should be released into a suitable drain to prevent injury or property damage.
NOTE : If the temperature and pressure relief valve on the hot water heater discharges periodically, this may be due to thermal expansion in a closed water system. Contact the water supplier or a qualified service technician to correct this. Do not plug the relief valve outlet.

At least once a year, lift and release the lever handle on the temperature and pressure (T&P) relief valve, located on the right side of the water heater. Flush several gallons to the open drain below, confirming that the water flows freely through the T&P valve and discharge line.

Water Tank

Draining and Flushing the Water Heater
Over time, minerals contained in the water supply will begin to accumulate in the water heater’s tank. Drain and flush the water heater at least once a year to clean any mineral deposits from the tank and ensure they do not interfere with proper functioning of the water heater.
If the water supply is particularly hard (high in mineral content), it may be necessary to perform this process more often.

Draining the Tank :

1. Turn off the water heater and turn off gas to the unit. (See To Turn Off Gas To Appliance, page 7.)
2. Attach a garden hose to the drain valve located at the bottom of the unit and direct to a suitable drain.
3. Turn off the cold water supply.
4. Admit air to the tank by opening a hot water faucet or lifting the handle on the relief valve.
5. Open the drain valve.

Flushing the Tank :

1. Follow the steps above to drain the water heater.
2. Once the water heater is empty, with the drain valve open and garden hose attached to the drain valve, turn on the cold water supply.
3. Allow several gallons to flush through the drain valve and hose to an open drain.
4. Turn off the water supply and allow any water remaining in the tank to drain.
5. Repeat steps 3 and 4 until water runs clear.
6. Close the drain valve and completely fill the tank before turning on gas and relighting the unit. The tank is full when water runs continuously from an open hot water faucet.
   Flushing should be done with an empty tank to promote additional removal of sediment.

Anode Rod Maintenance and Service

Anode rods are designed and installed to protect and extend the life of residential water storage tanks.
The anode rod must be removed from the water heater’s tank and inspected annually, and replaced when more than 6” (15.2 cm) of core wire is exposed at either end of the rod. *NOTE: Artificially softened water will cause the anode rod to consume more rapidly.
The gas and cold water supply must be turned off before servicing the anode rod.
NOTICE : Do not remove the anode rod from the water heater’s tank except for inspection and/or replacement, as operation with the anode rod removed will shorten the life of the glass-lined tank and will void warranty coverage.
Some areas have water conditions that may cause an odor to develop in the water heater. Special alloy replacement rods are available to address this condition.
*NOTE : Failure to replace the anode rod when consumed voids the warranty for the tank. Warranty coverage for all other components remains intact and is unaffected by this maintenance requirement.
The replacement anode rod and the inspection for consumption are not covered by the warranty.

Inspecting the Anode Rod:

1. Turn off the water heater and drain 1-2 gallons of water from the tank. (Refer to Draining the Tank, page 11.)

2. Remove the anode cap and foam insulation beneath it with a flathead screwdriver. (Refer to illustration below.)

3. Unscrew the anode rod using a 1 1/16” socket/wrench and lift it out of the water heater.

4. Inspect the anode rod. If more than 6” of core wire is exposed, the anode rod should be replaced. (Refer to illustration below.) If the anode rod has not been depleted, reinsert it into the water heater following steps 2-6 below.
   DO NOT touch the vent hood or vent pipe located in front of the anode rod. These are very hot and present a burn hazard.
   

Installing the Anode Rod:

1. If a new anode rod is required, be sure to purchase the same type. For further information, contact a qualified service technician or GEA Customer Support at GEAppliances.com/waterheater.
2. Apply pipe joint compound or pipe thread sealant tape to the threads of the anode rod.
3. Insert the anode rod into the water heater and tighten with a torque wrench to 50 +/- 5 ft-lbs. of torque.
4. Close the drain valve, turn on the water supply and open a hot water faucet to remove any air trapped in the water lines.
5. Check for any leaks and repair.
6. Ensure that the water heater is completely full before relighting it. (Refer to Lighting Instructions,)

Gas Control/Thermostat Inspection

Once a year, visually inspect the gas control/thermostat cover, gas control knob and status light for any physical damage. Check for any loose connections or frayed wires as well.
If damage to any of these components is detected, call a service technician to repair or replace the gas control/ thermostat.

Pilot Light and Burner Inspection

Once a year, visually inspect the pilot light, then the main burner while in operation. Through the sight glass, confirm that both flames are blue and exhibit the pattern shown in the illustrations below. If a different flame pattern or color is noted or soot has built up on the burner, turn off the water heater and call a qualified service technician.
Low NOx Burner

The pilot light and main burner are in a sealed chamber. Only a qualified service technician should access this chamber. Refer to Sealed Burner Assembly Warning.

Ultra-Low NOx Burner

The Ultra-Low NOx burner surface will initially have a short blue flame, which will heat up the burner and change its radiant surface bright orange (after ~30 minutes of operation). If a large flame pattern or different flame color is observed, turn off the water heater and call a qualified service technician.

Water and Gas Systems

Once a year, visually inspect the water pipes and connections, repairing any leaks or damaged fittings.
If you smell gas, refer to Lighting and Shutdown. Check the water heater’s venting system:

1. Visually inspect the vent hood and vent pipes to ensure they are firmly attached.
2. Visually check for soot or any physical deterioration of the venting system. If corrosion or soot are detected, call the local gas utility to address the problem and replace the venting system before placing the water heater back in operation. (Not covered under the product warranty.)

INSTALLATION INSTRUCTIONS

LOCAL INSTALLATION REGULATIONS
This appliance must be installed in accordance with local codes or, in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA B149.1. Not for Installation in a Manufactured Home (Mobile Home).

LOCATION
The water heater should be installed indoors, in a dry, level area where the tank and water lines are protected from freezing temperatures. If needed, shims can be used under the base of the unit to level it.
All water heaters are subject to leaking, due to the corrosive properties of water over time. The water heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent of the appliance or to lower floors of the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. A ground floor or basement installation is suggested. Inspect and maintain the water heater according to this manual to minimize the potential for leakage.

Catch Pan Installation (If Required)

NOTE : The auxiliary catch pan MUST conform to local codes. Catch Pan Kits are available from the store where the water heater was purchased or GEApplianceparts.com. The catch pan outer diameter (OD) should be 3” (7.62 cm) minimum larger than the Water Heater base diameter. The pan must not restrict combustion air flow.

The installation must allow sufficient airflow for combustion and ventilation, and should be as close to a gas vent or chimney as possible. Avoid areas where the water heater could be exposed to flammable liquids and vapors or a corrosive atmosphere.
The water heater can be installed on combustible flooring, but not directly on carpet. If the water heater must be located in a carpeted area, install a wood or metal panel as a barrier between the water heater and carpet; the panel should be 3” larger than the water heater in all directions.
To minimize thermal loss, the water heater should be close to the areas of greatest demand. Insulated water lines also help to maintain optimal temperatures from water heater to faucet.
The installation must allow sufficient access to the top, front and sides of the water heater for service.
Moving the water heater for service is not covered under the warranty.
For installation requiring earthquake straps, minimal clearance around the sides of the water heater is acceptable. In this case, additional clearance should be provided on the opposite side of the unit to allow for service access. Refer to For Installations in the State of California.

Refer to the rating plate beside the gas control/ thermostat on the front of the water heater for further details.

AIR SUPPLY AND VENTILATION

Proper air supply and ventilation are essential to the safe, effective operation of this residential gas water heater. Air supply and ventilation must be in accordance with local codes or, in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA B149.1.
Air Supply
This water heater is designed for use as a Category I, natural draft, non- direct vented water heater which takes its combustion air either from the installation area or from air ducted to the unit from the outside.
If the water heater is installed in an open room of a conventionally constructed building, sufficient air is typically present for proper combustion and ventilation.
However, if the water heater is installed in a confined space or tightly insulated home, additional provisions must be made for combustion and ventilation air. A confined space offers less than 50 cubic feet of air per 1,000 BTUH (British thermal units per hour) for all the appliances in that space. Each appliance’s BTUH requirements should be listed on its rating plate.
Air supplied only from inside building : Air must be supplied through two permanent openings of equal size located within 12” from floor and 12” from ceiling for confined spaces. The free area of each opening must be at least 1 in2 for every 1000 Btuh of the total input rating of all appliances located in the space, but not less than 100 in2.
Air supplied only from Outdoors : Air supplied from two openings (as specified above), must have a minimum free area opening as shown below for the total input rating of all appliances installed in space: Vertical Ducts or direct to outdoors: 1 in2 for every 4000 Btuh.
Horizonal Ducts: 1 in2 for every 2000 Btuh. Air supplied from a Single Duct opening must provide a free opening of 1 in2 for very 3000 Btuh.
The minimum rectangular duct opening must be no less than 3”.
If duct openings which supply combustion and ventilation air are to be covered with a protective screen, the net free area (opening in material) of the covered material must be used in determining the size of the opening. Protective screen for openings MUST NOT be smaller than a ¼” mesh opening to prevent clogging.
DO NOT block or obstruct any of the combustion air inlet openings located around the perimeter of the water heater.
Without an adequate supply of clean air, the water heater’s pilot light will not function properly, and excessive amounts of carbon monoxide may be produced.

Corrosive Atmospheres
A corrosive atmosphere is created when compounds from aerosol sprays, cleaning products such as bleach and detergents or other chemicals become airborne and are drawn into the combustion air supply of a water heater or other gas appliance. When these compounds pass through the gas flame, they create corrosive elements that shorten the life of the appliance. Damage due to a corrosive atmosphere is not covered under the warranty.

Ventilation
When an existing Category I appliance is removed or replaced, the original venting system may no longer be sized to properly vent the attached appliances. Vents must be adequately sized per local codes or in absence of local codes, the National Fuel Gas code to prevent formation of condensate, leakage, and spillage of flue gases.
The ventilation system for this water heater must be properly installed by a qualified service technician and free from any obstructions. The vent should not be shared by any powervented appliance, nor should a damper be used anywhere in the system.
The water heater shall not be connected to a chimney flue serving a separate appliance designed to burn solid fuel.
The new vent hood (provided with the water heater) must be attached to the gas vent or chimney by vent pipes. The diameter of the vent pipes must match that of the vent hood or be larger.
A UL listed Type B double-wall or single-wall metal vent pipe must be used. Follow vent pipe manufacturer’s instructions for clearance to combustible materials. Clearance for single-wall vent pipe should never be less than 6″.
At least 12” of vertical vent pipe is recommended from the vent hood. Horizontal pipes must maintain a vertical pitch of at least 1/4” per foot, and the termination must be vertical.
Vent joints must be secured by an approved method, such as sheet metal screws.
After the water heater’s main burner has been in operation for 5 minutes, the vent hood can be tested for spillage by holding a lighted match or candle close to the vent hood relief opening. The smoke or flame should be pulled towards the opening.

THERMAL EXPANSION
If the home’s inlet water line includes a check valve, this will prevent water from flowing back into the city’s water supply, creating a closed water system in the home. Heated water expands, causing increased pressure, which is then trapped in a closed water system. Referred to as thermal expansion, this rapid pressure increase can cause the water heater’s relief valve to operate (releasing water) during heating cycles, potentially causing premature failure of the valve or the water heater. To control thermal expansion, install a thermal expansion tank in the cold water line between the water heater and check valve, as shown in the next illustration, page 16. Contact your installing contractor, water supplier or plumbing inspector for additional information.

WATER SUPPLY AND DRAINAGE

Refer to the illustration below for recommended installation. The HOT and COLD water connections are 3/4” NPT (National Pipe Thread) and are clearly marked on all models. Use 3/4” female NPT fittings with sealant suitable for potable water when connecting to the inlet/outlet ports. The installation of unions is recommended on the HOT and COLD water connections so that the water heater may be easily disconnected for service. Piping should be routed to allow for anode rod inspection and service.
NOTE : Install a shut-off valve in the cold water line near the water heater.
This will allow for easier service and maintenance of the unit.
IMPORTANT : Do not apply heat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to adapter before fitting the adapter to the COLD water connections on the water heater. Any heat applied to the HOT or COLD water connections will permanently damage the internal plastic lining in these ports.
Install a vacuum relief valve and/or anti-siphon device when required by local jurisdictions.

HOT AND COLD PIPE INSULATION (if supplied with product)
For increased energy efficiency, some water heaters have been supplied with two 24” sections of pipe insulation. Install the insulation according to the illustrations on the right, as best meets your requirements.
Typical vertical piping

Typical horizontal piping

TEMPERATURE AND PRESSURE RELIEF VALVE

Risk of Unit Damage – The pressure rating of the relief valve must not exceed 150 PSI (1.03 MPa), the maximum working pressure of the water heater as marked on the rating plate.

A new combination temperature and pressure (T&P) relief valve, complying with the Standard for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22/CSA 4.4, is supplied and must remain installed in the opening provided and marked for this purpose on the water heater. No valve of any type should be installed between the relief valve and the tank. Local codes shall govern the installation of relief valves.
The BTUH rating of the temperature and pressure relief valve must not be less than the input rating of the water heater as indicated on the rating plate located on the front of the heater (1 watt=3.412 BTUH).
Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact live electrical parts or persons and to eliminate potential water damage.
Piping used should be of a type approved for hot water distribution. The discharge line must be no smaller than the outlet of the valve and must pitch downward from the valve 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 the discharge line.

(Model appearance may vary)

To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and pressure protective equipment required by local codes and no less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22 /CSA 4.4. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater. Install the valve into an opening provided and marked for this purpose in the water heater, and orient it or provide tubing so that any discharge from the valve exits only within 6 inches above, or at any distance below, the structural floor, and does not contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstance.

TO FILL THE WATER HEATER

Risk of Unit Damage – The tank must be full of water before the water heater is turned on. The water heater warranty does not cover damage or failure resulting from operation with an empty or partially empty tank.

1. Check that the drain valve is completely closed.
2. Open the shut-off valve in the cold water supply line.
3. Open hot water faucets slowly, allowing air to vent from the water heater and pipes.
4. Wait until there is a steady flow of water from the hot water faucets; this indicates that the water heater is full.
5. Check connections and pipes for any leakage.
   When the water heater is first filled with water, condensation may form on the tank and fittings.
   During use, condensation can be caused by a heavy water draw and very cold inlet water temperature.

This condition is not unusual and will resolve after the water is heated. If condensation persists, examine fittings for potential leaks and repair as required.

GAS SUPPLY

Only connect this water heater to the type of gas listed on its rating plate. Any attempt to adapt the water heater for use with a different type of gas could cause hazardous operating conditions.
The gas supply line should be composed of an approved gas piping material such as steel and properly sized for the water heater. Install an ANSI certified gas appliance connector or ground joint union in the gas line close to the water heater.
Any flexible connectors in the gas line must be 36” or shorter. Joint compound should be used sparingly on male threads only and must be resistant to liquid petroleum (LP) gas.
The National Fuel Gas Code (NFGC) requires that a manual gas shut-off valve be installed.
A sediment trap must be installed downstream of the shut-off valve, as close to the appliance as possible.
Refer to the illustration below.

Connect the pipe to the gas control/thermostat inlet using a maximum torque of 40 ft-lbs. torque.
Gas pressure to the gas control/thermostat inlet must not exceed 14” w.c. for natural gas or LP gas.
For purposes of input adjustment, the minimum inlet gas pressure (with main burner on) is shown on the water heater rating plate. If gas pressure is not within the acceptable range, contact your gas provider.

Pressure Testing

• Gas test pressures exceeding 14” w.c. (1/2 PSI or 3.5 kPa) require disconnecting the water heater and gas shut-off valve from the gas supply line.
• Gas test pressures of 14” w.c. (1/2 PSI or 3.5 kPa) or lower require isolating the water heater from the gas supply line by closing the gas shut-off valve.

Leak Testing

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 pressure before placing the appliance in operation.
• Turn ON the manual gas shut-off valve near water heater and check for leaks by applying a soapy water mixture on all gas fittings, including the factory connections to the Combination Gas Control (thermostat). Presence of bubbles indicate a gas leak, which must be corrected before completing installation.

High Altitude

Do not install the water heater above the altitude specified on its rating plate.
Installation above the certified altitude may cause the water heater to produce excessive amounts of carbon monoxide, which could cause serious injury or death.
The water heater is certified for operation at high altitudes. Please see the rating plate on the water heater for maximum altitude.

INSULATION BLANKETS
This water heater is designed for energy efficiency.
An insulation blanket is NOT RECOMMENDED, unless required by local codes.
Any damage caused by an insulation blanket or other unapproved device is not covered under the warranty.
Use of such devices can shorten the life of the water heater and pose a hazard to persons or property.
If an insulation blanket is required by local codes:

• DO NOT cover or attempt to relocate warning labels on the water heater.
• DO NOT insulate the top of the water heater; this will interfere with proper functioning of the vent hood.
• DO NOT cover the gas control/thermostat, gas valve, burner access door or temperature and pressure relief valve.
• DO NOT insulate the bottom of the water heater or cover the combustion air inlets.
• FREQUENTLY INSPECT the insulation blanket to ensure that it is securely in position and is not restricting airflow to the combustion air inlets at the base of the water heater.

COMBINATION POTABLE WATER AND SPACE HEATING

This water heater is suitable for combination potable water and space heating applications; it is not suitable for space heating alone.
If installed for combination water and space heating, components in both systems must be suitable for potable water. DO NOT connect the water heater to components that have been previously used for space heating alone, as they may be contaminated with toxic chemicals. Never introduce boiler treatment or other toxic chemicals into pipes or components connected with the water heater, as this will affect the potable water supply. If the space heating system requires water at a temperature higher than 120°F (49°C), a mixing valve (meeting the Standard for Temperature Actuated Mixing Valves for Hot Water Distribution Systems, ASSE 1017) must be installed in the potable hot water line to reduce the danger of scalding.
Installation must comply with local and national codes.
NOTE : A maximum distance of 50’ – 0” from the water heater to fan coil (developed length) is required in the state of Massachusetts.
