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.

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 page 7 provides 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 5

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 sediment trap (if not already incorporated 

as part of the water heater) as shown. The sediment 

trap 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 Piping

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.

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 pilot 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 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.
