NOTICE: The National
Fuel Gas Code (NFGC)
mandates a manual gas
shut-off valve: See (NFGC)
for complete instructions.
Local codes or plumbing
authority requirements
may vary from the instruc-
tions or diagrams provided
and take precedent over
these instructions.
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 /CSA 4.4, is factory
installed 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 psi (1,034 kPA),
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 com-
plete 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 must
be installed in the discharge line.
