Gas Supply

Gas Requirements

IMPORTANT: 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)-latest

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 3

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.

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. While purging the gas piping system of air, make

sure that the fuel is not spilled in the area of the water heater

installtion, 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 the manual.

Gas Pipe Capacity

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.

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.
