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 gascancauseproblemswhichcanresult in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE. If you have any questions or doubts consult
your gassupplieror localutility.
AWARNING
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 which emit flammable
vapors, may be impropedy stored or used in such areas.
The gaswater heater pilot light or main burner can ignite
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 be stored or
used in the same room or area containing a gas water
heater or other open flame or spark producingappliance.
NOTE: Flammable vapors may be drawn by air currents
from other areasof the structure to the appliance.
_WARNING
If this water heater will be used in beauty shops,barber
shops, cleaning establishments, or salf-servicelaundries
with dry cleaning equipment, it is imperative that the
water heater or water heaters be installed so that 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 Fuel Gas Code, ANSI Z223.1, also referred to as
NFPA 54 for specificsprovided concerningair required,
AWARNING
A fire can start if €orals suchas clothing,
cleaningmaterials, or flammable liquidsare placedagainst
or next to the water heater,

At the time of manufacture this water heater was pro.
vided with a combination temperature.pressures relief
valve certified by a nationally recognized testing labora-
tory that maintains periodic inspection of production of
listed equipment or materials, as meeting the require-
ments 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 valve must meet the require-
ments of local codes, but not lessthan a combination
temperature and pressurerelief valve certified as meet-
ing the requirements for Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems,
ANSI Z21.22 bya nationally recognized testing laborato-
ry that maintains periodic inspection of production of
listedequipment or materials.
The valve must be marked with a maximum set pressure
not to exceed the marked hydrostatic working pressure
• I
of the water heater (150 Ibs.lsq. in.) and a discharge
capacity not less than the water heater input rate as
shown on the model rating plate. (Electric heaters
watts divided by 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 tumperature-pressure relief valve
installedin the designatedopeningin the water heater in
placeof 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. Position the valvedownward and provide
tubing sothat any dischargewill exit onlywithin 6 inches
above, or at any distance below the structural floor. Be
certain that no contact is made with any live electrical
)art. The discharge opening must not be blocked or
reduced in size under any circumstances. Excessive
length,over 30 feet, or useof more than four elbowscan
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. Do not connect tubing
directly to dischargedrain unlessa 6" air gap is provided.
To prevent bodily injury, 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 is not connected to a drain or other suitable
means, the water flow may causeproperty damage.
The Discharge Pipe:
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 listed for 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 an adequate drain.
Must not have any valve between the relief valve and
tank.
