Water heater has a main
burner and pilot flame. The
pilot flame:
1. is on all the time and
2. will ignite flammable vapors
Vapors:
1. cannot be seen,
2. are heavier than air,
3. go a long way on the floor
and
4. can be carried from other
rooms to the pilot flame by
air currents.
pilot flames are at least 18”
above the floor. This will reduce,
but not eliminate, the risk of
vapors being ignited by the main
burner or pilot flame.
Vapors from flammable
liquids will explode and
catch fire causing death or
severe burns.
Do not use or store flammable
products such as gasoline
solvents or adhesives in the same
room or area near the water
heater.
Keep flammable products:
1. far away from heater,
2. in approved containers,
3. tightly closed and
4. out of children’s reach.
Installation:
Do not install water heater where
flammable products will be
stored or used such as a garage,
basement, storage area or utility
room unless the main burner and

PRESSURE BUILD-UP IN
CLOSED WATER SYSTEMS
The water utility supply meter may contain a check valve,
back flow preventer or water pressure reducing valve. This will
create a closed water system. During the heating cycle of the
water heater, the water expands creating a pressure build-up in
the water system. A temperature and pressure relief valve must
be installed on the water heater (150 PSI maximum pressure
setting. See Temperature and Pressure Relief Valve). To
prevent the temperature and pressure relief valve from
discharging hot water, loss of energy, and reduce the possible
build-up of lime on the temperature and pressure relief valve
seat.
AN EXPANSION TANK MUST BE INSTALLED on the cold
water supply line. For every 50 U.S. gallons of stored water,
the expansion tank must have a minimum capacity of 1.5
U.S. gallons.
If water heater is installed in a closed water system, contact the
water supplier or local plumbing inspector on how to control
this situation.
CONSUMER RESPONSIBILITIES
THIS MANUAL HAS BEEN PREPARED TO ACQUAINT
YOU WITH THE INSTALLATION, OPERATION AND
MAINTENANCE OF YOUR GAS WATER HEATER AND
TO PROVIDE IMPORTANT SAFETY INFORMATION.
WE URGE YOU TO READ ALL INSTRUCTIONS
THOROUGHLY
before attempting installation or operation of
your water heater. Keep these instructions for future reference.
The manufacturer of this water heater will not be liable for any
damages caused by failure to comply with the installation and
operating instructions outlined on the following pages. These
instructions are a guide for the correct installation of your
water heater. If you lack the necessary skills required or have
difficulty following the directions, you should not proceed but
get help from a qualified person for that part of the installation
you do not understand. Your gas-fired water heater is design-
certified by the American Gas Association Laboratories. The
installation should conform with the local code or the
authority having jurisdiction, or in the absence of such, the
National Gas Code. ANSI Z223.1 (NFPA 54) 1992. A copy of
the 1992 edition of the Code can be purchased from A.G.A.
Order Processing, 1515 Wilson Boulevard, Arlington, VA
22209 [phone]. A rating plate identifying your water
heater will be found next to the gas control valve (thermostat).
When referring to your water heater always have the
information listed on the rating plate readily available.

LOCATION
Location selection should be as close to the stack or chimney
as practical and as centralized with the piping system as
possible. Water heater should be located in an area not subject
to freezing temperatures.
The water heater should be located so that the controls and
drain are easily accessible (at least 24 inches in front of the
water heater). The heater should be located in an area where
leakage of the tank or connections will not result in damage to
the area adjacent to the water heater or to lower floors of the
structure. When such locations cannot be provided, a suitable
drain pan must be installed under the heater. Such pans must
limit the water level to a maximum depth of 1 3/4 inches
inside of pan, have a minimum length and width of at least
two inches greater than the diameter of the heater, and must be
piped to an adequate drain. The pan must not restrict
combustion air flow. (Figure 6)
Under no circumstances is the manufacturer to be held liable
for any water damage in connection with this water
heater.
WARNING
When this heater is installed directly on carpeting, carpeting
must be protected by a metal or wood panel beneath the
appliance extending beyond the full width and depth of the
appliance by at least 3 inches in any direction, or if the
appliance is installed in an alcove or closet, the entire floor
must be covered by the panel. FAILURE TO HEED THIS
WARNING MAY RESULT IN FIRE HAZARD.

RESIDENTIAL AREA WHICH MAY NOT BE SUITABLE FOR
HEATER INSTALLATION
would include those areas where flam-
mable liquids (such as gasoline, solvents, liquefied propane or
butane, etc.) or other substances (such as adhesives, etc.) all of which
emit flammable vapors, may be improperly storedor used. Because of
natural air movement in a room or other enclosed space, flammable
vapors can be carried some distance from where their liquids are being
used or stored. The gas water heater pilot flame or main burner can
ignite such vapors. The resulting flash-back and tire can cause death
or serious burns to anyone in the area, as well as property damage.
For these reasons the water heater must not be installed in an area
where there may be flammable vapors. If such flammables must be
used, all gas burning appliances in the vicinity must be shut off,
including their pilot lights, to avoid vapors igniting and open doors
and windows for ventilation .
If installation in a garage is your only option, 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
BUT NOT eliminate the chances of flammable vapors from a spill
being ignited, gasoline or other flammable substances must never be
stored or used in the same room or area containing a gas water heater
or other open flame or spark-producing appliance.
REMEMBER: Flammable vapors may be drawn to this water heater
from other areas of the structure by air currents.
NOTE: HEATER SHALL BE LOCATED OR PROTECTED
SO IT IS NOT SUBJECT TO PHYSICAL DAMAGE BY
MOVING VEHICLES OR AREA FLOODING.

DISCHARGE OF PURGED GASES
When removing purged gases from a piping system, care should
be taken not to create a hazardous condition, such as discharging
the gases into a confined area or in an area which contains an
ignition source.
