WATER HEATERS EQUIPPED FOR ONE TYPE GAS
ONLY: This water heater is equipped for one type gas
only. Check the model rating plate near the gas control
valve for the correct gas. DO NOT USE THIS WATER
HEATER WITH ANY GAS OTHER THAN THE ONE
SHOWN ON THE MODEL RATING PLATE. Failure to
usethe correct gascancauseproblemswhich canresult in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE. If you have any questions or doubts consult
yourgassupplieror localutility.
_,VQARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQ-
UIDS (VAPORS) ARE LIKELY TO BE PRESENT OR
STORED (GARAGES, STORAGE, AND UTILITY AREAS,
ETC): Flammable liquids (such as gasoline, solvents,
propane(LP) or butane, etc.), all of whichemit flammable
vapors, may be improperly stored or used in such areas.
The gaswater heater pilot light or main burner canignite
such vapors. The resulting flashback and fire can cause
death or serious burns to anyone in the area, as well as
property damage.
If installation in such areas is your only option, then the
installation must be accomplishedin a way that the pilot
flame and main burner flame are elevated from the floor
at least 18 inches.While this may reduce the chancesof
flammable vaporsfrom a floor spillbeing ignited, gasoline
and other flammable substancesshouldnever bestored or
used in the same room or area containing a gas water
heater or other open flame or sparkproducingappliance.
NOTE: Flammable vapors may be drawn by air currents
from other areasof the structure to the appliance.
_,WARNING
If this water heater will be usedin beauty shops,barber
shops,cleaning establishments, or self-service laundries
with dry cleaning equipment, it is imperative that the
water heater or water heaters be installed sothat com-
bustion and ventilation air be taken from outside these
areas. Refer to the "Locating The New Water Heater"
section of this manual and also the latest edition of the
National FuelGas Code, ANSI Z223.1, also referred to as
NFPA 54 for specificsprovidedconcerningair required.
_,WARNING I
A fire can start if combustible materials suchas clothing,
cleaningmaterials, or flammable liquidsare placedagainst
or next to the water heater.
_,WARNING
At the time of manufacture this water heater was provid-
edwith a combination temperature-pressures relief valve
certified by a nationally recognized testing laboratory
that maintains periodic inspectionof production of listed
equipment or materials, as meeting the requirements
for Relief Valves and Automatic Gas Shutoff Devices for
Hot Water Supply Systems, and the latest edition of
ANSI Z21.22 and the code requirements of ASME. If
replaced, the valvemust meet the requirements of local
codes,but not lessthan a combination temperature and
_ressure relief valve certified as meeting the require-
ments for Relief Valves and Automatic Gas Shutoff
Devicesfor Hot Water Supply Systems,ANSI Z21.22 by
a nationally recognized testing laboratory that maintains
_eriodic 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./sq. in.) and a discharge
capacity not less than the water heater input rate as
shown on the model rating plate. (Electric heaters -
watts dividedby 1000x 3415 equal BTU/Hr. 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
different from the one furnishedwith the water heater.
Compliance with such local requirements must be satis-
fied 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
daceof the factory furnishedvalve.
For safeoperation 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. Positionthe valve downwardand pro-
vide tubing so that any dischargewill exit only within 6
inches above, or at any distance below the structural
floor. Be certain that no contact is made with any live
electrical part. The discharge opening must not be
blocked or reduced in size under any circumstances.
Excessivelength, over 30 feet, or use of more than four
elbows can cause restriction and reduce the discharge
capacity ofthe valve.
No valve or other obstruction is to be placed between
the relief valve and the tank. Do not connect tubing
directly to dischargedrain unlessa 6" air gap isprovided.
To prevent bodilyinjury, hazard to life, or property dam-
age, the relief valve must be allowed to dischargewater
in quantities should circumstances demand. If the dis-
charge pipe isnot connected to a drain or other suitable
means, the water flow may causeproperty damage.
The DischargePipe:
• Must not be smaller in sizethan the outlet pipe sizeof
the valve, or have any reducing couplings or other
restrictions.
• 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
dischargepipe.
• Must terminate at anadequate drain.
• Must not have any valve between the relief valve and
tank.
