' ' ' &WARNING
WATER HE_ATERs 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 gascan cause problemswhich canresu_ in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE. If you have any questions or doubts consult
your gassupplieror localutility.
&WARNING
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 are.as.
The gaswater heater pilot light or main burner can igmte
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 isyour only option, then the
installation must be accomplishedin a way that the pilot
flame end main burner flame are elevated from the floor
at least 18 inches.While this may reduce the chancesof
flammable vaporsfrom a floor spillbeingignited, gasoline
and other flammable substancesshouldnever be storedor
used in the same room or area containing a gaswater
heater or other open flame or sparkproducingappliance.
NOTE: Flammable vapors may be drawn by air currents
from other areasofthe structure to the appliance.
&WARNING
If this water heater will be used in 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 so that com-
bustion and ventilation alr be taken from outside these
areas. Refer to the "Facts to Consider About the
Location" section of this manual and also the latest edi-
tion of the National Fuel Gas Code, ANSI Z223.1, also
referred to as NFPA 54 for specificsprovided concerning
air required.

At'the time Of_nanu(_a_Kls V_aterhe_aterwasprovlcl-
ed with a combination temperature-pressures relief valve
certified by a nationally recognized testing.laboratory
that maintains periodic inspectionof product|onof listed
equipment or materials, asmeeting the requirements for
Relief Valves and Automatic Gas Shutoff Devicesfor 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 oflocal codes,but
not less than a combination temperature and pressure
relief valve certified as meeting the requirements for
ReliefValvesand Automatic Gas Shutoff Devicesfor Hot
Water Supply Systems, ANSI Z2i.22 by • nationally rec-
ognized testing laboratory that maintains periodic
inspection of production of listed equipment or
materials.
The valvemust be marked with a maximum set pressure
not to exceed the marked hydrostaticworking pressure
of the water heater (150 Ibs./sq. in.) and a discharge
capacity not lessthan the water heater input rate as
shown on the model rating plate. (Electric heaters
watts divided by 1000 x 3415 equalBTU/Hr. rate.)
Your local jurisdictional authority, while mandating the
use of a temperature-pressure relief valve complying
with ANSI Z21.22 and ASME, mayrequire a valvemodel
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
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-prassure relief valve must be installed
directly into the fitting of the water heater designatedfor
the relief valve. Positionthe 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 efl:mwscan
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 isprovided.
To prevent bodily injury, hazard to life, or property dam-
age, the relief valve must be allowedto discharge water
in quantities should circumstances demand. If the dis-
chargepipe isnot connected to a drain or other suitable
means,the water flowmay 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
restrictions.
Must not be pluggedor blocked.
Must be ofmaterial listedfor hot water distribution.
Must be installed so as to allow complete drainage of
boththe temperature-pressure relief valve,and the dis-
chargepipe.
• Must terminate atan adequate drain.
• Must not have any valve between the relief valve and
tank.
