Installing the water heater
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, and the
water may also be seen beneath the water heater.
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.
!
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.
To Fill the Water Heater
Make certain that 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.
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.
