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 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 satisfied 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

consult your gas supplier or local utility,
AWARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS)ARE LIKELYTO BEPRESENTOR 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

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
damage, the relief valve must be allowed to discharge
water in quantities should circumstances demand. If
the discharge pipe is not connected to a drain or other
suitable means, the water flow may cause property
damage.
The Discharge Pipe:
• Must notbe 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.
AWARNING
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 combustion 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,

AWARNING
AWARNING
VENT DAMPERS - Any vent damper, whether it is
operated thermally or otherwise must be removed if
its use inhibits proper drafting of the water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiency in excess of 80%
may produce a relatively low flue gas temperature.
Such temperatures may not be high enough to properly open thermally operated vent dampers. This
would cause spillage of flue gases and may cause
carbon monoxide poisoning.
Vent dampers must bear evidence of certification as
complying with the latest edition of American
National Standard ANSI Z21.68 (ANSI Z21.66 & 67,
respectively, cover electrically and mechanically actuated vent dampers). Before installation of any vent
damper, consult your local gas utility for further
information,
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a
temperature which will satisfy clothes washing, dish
washing, and other sanitizing needs can scald and
permanently injure you upon contact. Some people
are more likely to be permanently injured by hot
water than others, These include the elderly, children,
the infirm, or physically/mentally
handicapped. If
anyone using hot water in your home fits into one of
these c_roupsor if there is a local code or state law
requiring a certain temperature water at the hot
water tap, then you must take special precautions. In
addition to using the lowest possible temperature
setting that satisfies your hot water needs, a means
such as a mixing valve, should be used at the hot
water taps used by these people or at the water
heater. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturers instructions for installation of the valves. Before changing
the factory setting on the thermostat,
read the
'_Temperature Regulation" section in this manual.
AWARNING
• The appliance and its individual shutoff valve must
be disconnected from the gas supply piping system
during any pressure testing of the gas system at
test pressures in excess ofl/2 pound per square
inch (3.SkPa).
• The appliance must be isolated from the gas supply piping system by closing its individual manual
shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal or
less than 1/2 pound per square inch (3.5kPa),
AWARNING
Soot build-up indicates a problem that requires correction before further use. Turn 'off" gas to water
heater and leave "off"
until repairs are made,
because failure to correct the cause of the sooting
can result in a fire or explosion causing DEATH, SERIOUS BODILY INJURY,OR PROPERTY DAMAGE.
AWARNING
AWARN[NG
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS]: Propane (L.P.) gas is heavier than air.
Should there be a leak in the system, the gas will settie near the ground. Basements, crawl spaces, skirted
areas under manufactured (mobile) homes (even
when ventilated), closets and areas below ground
level will serve as pockets for the accumulation of
this gas. Before attempting to light or relight the
water heater's pilot or turning on a nearby electrical
light switch, be absolutely sure there is no accumu-

very cold incoming water - can shock the thermostat into brief operation resulting in hotter and hotter layers of water closer to the top of the tank.
Changes in hot water usage patterns or raising the
temperature differential between the cut-on of the
thermostat and the cold water temperature will
usually eliminate the problem.
