Installing the water heater.

A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves 

and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22, is supplied and must 

remain in the opening provided and marked for the 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.

Relief Valve

The pressure rating of the relief valve 

must not exceed 150 PSI, the maximum 

working pressure of the water heater as 

marked on the rating plate. 
The Btuh rating of the relief valve must 

equal or exceed the Btuh input of the 

water heater as marked on its rating plate.
Position the outlet of the relief valve 

above a suitable open drain 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.

To Fill the Water Heater

Make certain that the drain valve is 

closed, then open the shut-off valve in the 

cold water supply line.
Open each hot water faucet slowly to 

allow the air to vent from the water  

heater and piping. 
A steady flow of water from the hot water 

faucet(s) indicates a full water heater.

Do not allow the flammable vapor sensor 

to become submerged in water.

WARNING: The tank 

must be full of water before 

heater is turned on. The 

water heater warranty does 

not cover damage or failure 

resulting from operation 

with an empty or partially 

empty tank.

Condensation

Condensation can form on the tank 

when it is first filled with water. 

Condensation might also occur with a 

heavy water draw and very cold inlet 

water temperatures. 
Drops of water falling on the burner can 

produce a sizzling or pinging sound.
This condition is not unusual, and will 

disappear after the water becomes heated. 

If, however, the condensation continues, 

examine the piping and fittings for 

possible leaks.
