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 DAMAGE. If you have any questions or doubts consult your gas supplier or local utility.
_,WARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQ- UIDS (VAPORS) ARE LIKELY TO BE PRESENT OR I STORED (GARAGES, STORAGE, AND UTILITY AREAS, ETC): Flammable liquids (such as gasoline, solvents, I 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 elevated 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 shouldnever 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 will be used in beauty shops, barber shops, cleaning astablishments, 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 air 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 specifics provided concerning air required.

A, WARNING
At the time of manufacture this water heater was provid- led with a combination temperature-pressures relief valve 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 Z21.22 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 pressure relief valve certified as meeting the require- ments for Relief Valves and Automatic Gas Shutoff
Devices for Hot Water Supply Systems, ANSI Z21.22 by a nationally recognized 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 beaters - watts divided by 1000 x 3415 equal BTUIHr. rate.)

floor. Be certain that _fo €0ntact_is ffiEde._with any live electrical part. The discharge opening must n'btbe
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 temperature-pressure relief valve, and the discharge pipe.
•Must ternljnate at an adequate drain.
•Must not have any valve between the relief valve and tank.
