WARNING

Explosion Hazard

• Gas leaks can not always be detected by smell.

• Gas suppliers recommend that you use a gas

detector approved by UL or CSA.

• For more information, contact your gas supplier.

• If a gas leak is detected, follow the “What to do if you

smell gas” instructions on the cover of this manual.

IMPORTANT: The gas supply pressure must not exceed the

maximum supply pressure as stated on the water heater’s rating

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.

NOTE: Air may be present in the gas lines and could prevent

the pilot from lighting on initial start-up. The gas lines should

be purged of air by a qualified technician after installation of

the gas piping system. While purging the gas piping system

of air, insure that the fuel is not spilled in the area of the

water heater installation, or any source of ignition. If the

fuel is spilled while purging the piping system of air follow

the “WHAT TO DO IF YOU SMELL GAS” instructions on

the cover of this manual.

GAS SUPPLY

WARNING

• 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.

Explosion Hazard

Gas Requirements

IMPORTANT: Read the rating 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 rating

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.

NOTE: Use pipe joint compound or teflon tape marked as

being resistant to the action of petroleum [Propane (L.P.)]

gases (See Figure 5.)

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.
