Instructions / Assembly

11
A new combination temperature and pressure relief valve, complying with the Standard for Relief
Valves 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.
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.
High Altitude
Ratings of gas appliances are based on
sea level operation.
This water heater is suitable and
certified for use at high altitude. Refer
to the altitude label on the water heater
for maximum allowable installation
altitude.
Please contact your local distributor or
place of purchase for a high altitude
model.
WARNING:
Failure to install a
water heater suitable
for the altitude at the
location it is intended
to serve, can result in
improper operation
of the appliance
resulting in property
damage and/or,
producing carbon
monoxide gas, which
could result in
personal injury, or
death.
