Installation
Instructions
(cont'd)
Temperature-Pressure
Relief Valve
AWARNING
I
At the time of
manufacture
this water heater was provided
with a combinationtemperature-pressures
relief
valve cer-
tified by a nationally
recognized
testing laboratory that
maintains periodic inspectionof production of listed
equip-
ment or materials, as meeting the
requirements
for Relief
Valves and Automatic Gas Shutoff Devicesfor Hot Water
SupplySystems,and the latest
edition
of ANSI Z21.22 and
the code
requirements
of ASME. If replaced, the valve
must meet the requirements of local codes, but not less
than a combination temperature and pressurerelief 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 maintainsperiodicinspectionof production
of listedequipment or materials.
The
valve must be marked with a maximum set pressure
not
to
exceed
the marked hydrostaticworking pressureof
the water heater (150 Ibs./sq.in.)
and
a dischargecapacity
not lessthan the water heater input rate as
shown
on the
model
rating
plate. (Electric
heaters
- watts divided by
1000x 3415 equal BTU/Hr. rate.)
Your localjurisdictional
authority,
while
mandatingthe use
of
a
temperature-pressure
relief
valve complying with
ANSI Z21.22 and ASME, may
require
a valve model differ-
ent
from the one furnishedwith the water heater.
Compliance with suchlocal
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 designatedopening in the water heater in
place of the factory furnishedvalve.
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 designatedfor
the
relief
valve. Positionthe valve downward
and
provide
tubing so
that
any dischargewill
exit
only within 6 inches
above,or at
any
distancebelow the structural floor. Be cer-
tain
that no contact is made with
any
live
electrical
part.
The dischargeopening must
not
be blocked or
reduced
in
size under any circumstances. Excessivelength, over 30
feet, or useof more than four
elbows
can cause
restriction
and reducethe dischargecapacityof the valve.
No valve or other obstruction is to be placed between the
relief
valve and the tank. Do
not
connecttubing directly to
dischargedrain unlessa 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 circumstancesdemand. If the dischargepipe is
not
connected to a drain or other suitable means, the water
flow may causeproperty damage.
The DischargePipe:
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 pluggedor blocked.
Must be of material listedfor hot water distribution.
Must be installed so as to allow complete drainage of
both the temperature-pressure
relief
valve, and the dis-
chargepipe.
Must terminate at an adequatedrain.
Must not have
any
valvebetweenthe raliefvalveandtank.
AWARNING
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 dischargedwill not cause any
bodily injury or property damage because the water may
be
extremely hot.
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.
