AWARNING
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 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 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 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 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 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 specifics provided concerning air required.
AWARNING1
Afire can start if combustible materials such as clothing, cleaningmaterials, or flammable liquidsare placed against
or next to the water heater. | |
AWARNING
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 less than a combination
temperature and pressure relief valve certified as meet-
ing the requirements for Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 by a nationally recognized testing laborato- ry 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 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 furnished with 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 installed in the designated opening in the water heater in place of the factory furnished valve.
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 designatedxf_;_. the relief valve. Position the valve downward and provide tubing so tha_any discharge will exit only within 6finches,

To prevent bodily injury, I_r_rd t_fife,-or-propertydam- 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 terminate at an adequate drain.
•Must not have any valve between the relief valve and tan_
