_k WARNIfNG
At the time of manufacture this water heater was provided
with a combination temperature-pressures
relief valve cer-
tified
by a nationally
recognized
testing
laboratory
that
maintains
periodic inspection of production of listed equip-
ment or materials, as meeting
the requirements for Relief
Valves and Automatic
Gas Shutoff Devices for Not Water
Supply Systems, and the current
edition of ANSI Z21,22
and the code requirements of ASHE+ If replaced, the valve
must meet the requirements
of local codes, but not less
than a combination
temperature
and pressure relief valve
certified as meeting
the requirements for Relief Valves and
Automatic
Gas Shutoff Devices for Hot Water
Supply
Systems, ANSI Z21.22 by a nationally recognized testing
laboratory that maintains
periodic inspection of production
of listed equipment or materials.
The valve must be marked with a maximum
set pressure
not to exceed the marked hydrostatic working pressure of
the water heater (150 Ibs. p.sJ.) and a discharge capacity
not less than the water heater input rate as shown on the
model
rating
plate. (Electric
heaters - watts divided by
1000 x 3412 equal BTU/Hro rate.)
Your local jurisdictional
authority,
while mandating the use
of a temperature-pressure
relief
valve complying
with
ANSI Z21.22 and ASME, may require a valve model differ-
ent from the one furnished with the water heater.
Compliance with such local requirements must be satisfied
by the installer or end user of the water heater
with a
locally
prescribed
temperature-pressure
relief
valve
installed in the designated opening in the water heater in
place of the factory furnished valve.
For safe operation
of the water heater, the relief valve
must
not be removed
from
it's designated
opening or
plugged.
The temperature-pressure
relief
valve must be installed
directly into the fitting
of the water heater designated for
the relief valve. Position the valve downward and provide
tubing so that any discharge will exit only within 6 inches
above, or at any distance below the structural floor. Be cer-
ta!n th_t .nocontact ismade with any th, e e!ectrical
p_rt+
The dischargeopening must not be blocked or reduced in
size under any circumstances.Excessive length,over 30
feet, or use of more than four elbows can cause restriction
and reduce the discharge capacity of the valve°
No valve or other obstruction is to be placed between the
relief valve and the tank. D,o not connect tubing directly to
discharge drain unless a 6 air gap is provided. To prevent
bodily injury, hazard to life, or property
damage, the relief
valve must be allowed to discharge
water
in quantities
should circumstances demand. If the discharge pipe is not
connected to a drain or other suitable means, the water
flow may cause property
damage.
The Discharge Pipe:
,
Must not be smaller in size than the outlet pipe size of
the valve,
or have any reducing
couplings or other
restriction+
Must not be plugged or blocked+
Must be of material listed for hot water distribution.
Must be installed so as to allow complete
drainage of
both the temperature-pressure
relief valve, and the dis.
charge pipe.
Must terminate
at an adequate drain.
Must not have any valve between the relief valve and
tank,
_k WARNING
The temperature-pressure
relief valve must be manually
operated at least once a year. Caution should be taken to
ensure that (I)
no one is in front of or around the outlet
of the temperature-pressure
relief valve discharge line,
and (2) the water manually discharged wilt not cause any
bodily injury or property
damage because the water may
be extremely
ho_
If after manually operating the valve, it fails to completely
reset and continues to release water, immediately,
close
the cold water inlet to the water heater, follow the drain-
ing instructions,
and replace the temperature-pressure
relief valve with a new one.
