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 can resu_ in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts consult your gassupplieror 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 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 is your only option, then the installation must be accomplished in 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 spill being 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
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.

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 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 causeproperty 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 pluggedor blocked.
Must be of material listed for hot water distribution.
Must be installed so as to allow complete drainage of both the
