WARNING: The pressure
rating of the relief valve
must not exceed 150 psi,
(1034 kPa), the maximum
working pressure of the
water heater as marked on
the rating plate.
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 be installed 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.
Temperature and Pressure Relief Valve
The BTUH rating of the relief valve must
not be less than the input rating of the
water heater as indicated on the rating
label located on the front of the heater
(1 watt=3.412 btu/h).
Connect the outlet of the relief valve to a
suitable open drain so that the discharge
water cannot contact live electrical parts
or persons and 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.
NOTICE: Auxiliary
catch pan MUST
conform to local codes.
The water heater should not be
located in an area where leakage of
the tank or connections will result in
damage to the area adjacent to it or to
lower floors of the structure. Where
such areas cannot be avoided, it is
recommended that a suitable drain
pan, adequately drained, be installed
under the water heater.
Under no circumstance will the
manufacturer be held liable for any
water damage in connection with
this water heater.
Drain pan kits are available from
the store where the water heater
was purchased, or any water heater
distributor.
