BTU/h rating equal to or greater than the input rating,
as shown on the water heater rating plate. It should
never be plugged or removed from the opening marked
for it on the water heater.
DO NOT
plug the temperature and pressure-relief
valve or its discharge line.
DO NOT
remove the
relief valve. Make sure the relief valve is properly
sized for the water heater. If the relief valve continuously
discharges water, call a qualified service technician
to correct the problem. Failure to follow these
instructions can result in property damage, personal
injury, or death.
If this relief valve should need to be replaced, use only
a new temperature and pressure-relief valve. Never
install an old or existing relief valve, as it may be dam-
aged or inadequate for the working requirements of
the new water heater. This new relief valve must meet
all local codes or, at a minimum, the requirements
listed above. Never install any other type of valve
between the relief valve and the water heater.
A discharge line must be installed into the relief
valve. The discharge line:
• Must not be smaller than the outlet pipe size of the
relief valve.
• Must not terminate less than six (6) inches (15.2
cm) and not more than twelve (12) inches (30.5
cm) above a floor drain.
• Must not be restricted in any way. Do not thread,
cap, or in any way restrict the end of this outlet.
• Must be of a material capable of withstanding
210
o
F (99
o
C) without distortion.
• Must be installed to allow complete drainage of the
relief valve and discharge line.
• Must terminate at an adequate free-flowing drain.
