WARNINGS (CONTINUED)
FOR INSTALLING PRESSURE AND
TEMPERATURE RELIEF VALVES IN
ACCORDANCE WITH AMERICAN NATIONAL
STD. Z21.22-1979. Combination pressure and
temperature relief valves with extension
thermostats must be installed so that the
temperature-sensing element is immersed in
the water within the top 6" (152 mm) of the
tank. They must be installed either in the hot
outlet service line or directly in a tank
tapping. Combination pressure and
temperature relief valves that do not have
extension elements must be mounted directly
in a tank tapping located within the top 6"
(152 mm) of the tank, and shall be adequately
insulated and located so as to assure
isolation from the flue gas heat or other
ambient conditions that are not indicative of
stored water temperature. TO AVOID WATER
DAMAGE OR SCALDING DUE TO VALVE
OPERATION, DRAIN PIPE MUST BE
CONNECTED TO VALVE OUTLET AND RUN
TO A SAFE PLACE OF DISPOSAL. Discharge
line must be as short as possible
and be the same size as the valve discharge
connection throughout its entire length.
Drain line must pitch downward from the
valve and must terminate between 1-1/2"
(38 mm) and 6" (152 mm) above the floor
drain where any discharge will be clearly
visible. The drain line shall terminate plain,
not threaded, with material serviceable for
temperatures up to 250°F (121°C) or greater.
Excessive length, over 30' (9144 mm), or use
of more than four elbows can cause a
restriction and reduce the discharge capacity
of the valve. No shut-off valve shall be
installed between the relief valve and tank, or
in the drain line. Valve lever must be tripped
periodically to assure that waterways are
clear. This device is designated for
emergency safety relief and shall not be used
as an operating control. The valves are set to
relieve at 150 psi (1034 kPa) or when water
temperature reaches 210°F (99°C). Read tag
on valve for additional information.
