Gas Supply

WARNING

Explosion Hazard

Use a new CSA approved gas supply line. Install a shut-off valve.

Do not connect a natural gas water heater to an L.P. gas supply.

Do not connect an L.P. gas water heater to a natural gas supply.

Failure to follow these instructions can result in death, explosion, or

carbon monoxide poisoning.

Gas Requirements

Read the data plate to be sure the water heater is made for the type of gas you will be using in your home. This information will be found on the data plate located near the gas control valve/thermostat. If the information does not agree with the type of gas available, do not install or light. Call your dealer.

NOTE: An odorant is added by the gas supplier to the gas used by this water heater. This odorant may fade over an extended period of time. Do not depend upon this odorant as an indication of leaking gas.

Gas Piping

The gas piping must be installed according to all local and state codes or, in the absence of local and state codes, the “National Fuel Gas Code”, ANSI Z223.1(NFPA 54)-current edition.

Tables 1 and 2 on the following page provide a sizing reference for commonly used gas pipe materials. Consult the “National Fuel Gas Code” for the recommended gas pipe size of other materials.

Refer to Figure 2

NOTE: When installing gas piping, apply approved pipe joint compound.

1.Install a readily accessible manual shut-off valve in

the gas supply line as recommended by the local utility. Know the location of this valve and how to turn off the gas to this unit.

2.Install a drip leg (if not already incorporated as part of the water heater) as shown. The drip leg must be no less than three inches long for the accumulation of dirt, foreign material, and water droplets.

3.Install a ground joint union between the gas control valve/thermostat and the manual shut-off valve. This is to allow easy removal of the gas control valve/thermostat.

4.Turn the gas supply on and check for leaks. Test all connections by brushing on an approved noncorrosive leak-detection solution. Bubbles will show a leak. Correct any leak found.

by the local utility.

Gas Pressure

IMPORTANT: The gas supply pressure must not exceed the maximum supply pressure as stated on the water heater’s data plate. The minimum supply pressure is for the purpose of input adjustment.

Gas Pressure Testing

IMPORTANT: This water heater and its gas connection must be leak tested before placing the appliance in operation.

•If the code requires the gas lines to be tested at a pressure exceeding 14” W.C., the water heater and its manual shut-off valve must be disconnected from the gas supply piping system and the line capped.

•If the gas lines are to be tested at a pressure less than 14” W.C., the water heater must be isolated from the gas supply piping system by closing its manual shut-off valve.

U.L. recognized fuel gas and carbon monoxide (CO) detectors are recommended in all applications and should be installed using the manufacturer’s instructions and local codes, rules, or regulations.

NOTE: Air may be present in the gas lines and could prevent the burner from lighting on initial start-up. The gas lines should be purged of air by a qualified person after installation of the gas piping system.

L.P. Gas Only

WARNING

Explosion Hazard

Have a qualified person make sure L.P. gas pressure does not exceed 13” water column.

Examples of a qualified person include: licensed plumbers, authorized gas company personnel, and authorized service personnel.

Failure to do so can result in death, explosion, or fire.
