Safety Precautions
I | AWARNING |
Improper installati_ | alteration, service |
or maintenance can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Refer to this manu- al for assistance or consult your local Sears Service
Center for further information.
_,WARNING
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
use the correct gas can cause problems which can result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAHAGE. If you have any questions or doubts consul your gas supplier or local utility.
_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 which emit flammable vapors, may be improperly stored or used in such areas.
The gas water 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 accomplished in a way that the pilot flame and main burner flame are e_evated from the floor
at least 18 inches. While this may reduce the chances of flammable vapors from a floor spill being ignited, gasoline and other flammable substances should never be stored or used in the same room or area containing a gas water
heater or other open flame or spark producing appliance. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.
_WARNING
if this water heater wlll be used in beauty shops, barber shops, cleaning establishments, or
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 specifics provided concerning air required.
I | AWARNING |
|
A fire can start | if co_ials | such as clothing, |
cleaning materials, or flammable liquids are placed against or next to the water heater.
&WARNING
At the time of manufacture this water heater was provid-
ed with a combination
certified by a nationally recognized testing laboratory that maintains periodic inspection of 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 Z21.2Z 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 rec-
ognized 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./sq. 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 1000 x 3415 equal BTUIHr. rate.)
Your local jurisdictional authority, while mandating the
use of a
Compliance with such local requirements must be satis- fied by the installer or end user of the water heater with
a locally prescribed
_lace of the factory furnished valve.
For safe operation of the water heater, the relief valve must not be removed from it'sdesignated 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 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. 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. Do not connect tubing directly to discharge drain unless a 6" air gap is provided.
To prevent bodily injury, hazard to life, or property dam- age, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the dis-
charge 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 restrictions.
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
Must terminate at an adequate drain.
Must not have any valve between the relief valve and tank.
