WARNING
This water heater must not be installed directly on carpeting. Car-
peting must be protected by a metal or wood panel beneath the
appliance extending beyond the full width and depth of the ap-
pliance by at least 3 inches (76.2mm) in any direction, or if the ap-
pliance is installed in an alcove or closet, the entire floor must be
covered by the panel. Failure to heed this warning may result in a
fire hazard.
WARNING
A gas water heater cannot operate properly without the correct
amount of air for combustion. Do not install in a confined area such
as a closet, unless you provide air as shown in the “Locating The
New Water Heater” section. Never obstruct the flow of ventilation
air. If you have any doubts or questions at all, call your gas com-
pany. Failure to provide the proper amount of combustion air can
result in a fire or explosion and can cause DEATH, SERIOUS BOD-
ILY INJURY, OR PROPERTY DAMAGE.
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 combustion and ventilation air be taken from out-
side these areas. Refer to the “Locating The New Water Heater”
section of this manual and also the current edition of the National
Fuel Gas Code, ANSI Z223.1, also referred to as NFPA 54 for
specifics provided concerning air required.
WARNING
The power vent water heater requires its own (separate) venting
system. It cannot be connected to an existing vent pipe or chim-
ney. It must be terminated to the outdoors. Failure to properly in-
stall the venting system can result in asphyxiation, a fire or explo-
sion and can cause DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
WARNING
No vent damper installation is compatible with this power vented
water heater design. No vent damper, whether it is operated ther-
mally or otherwise is to be installed on this power vented water
heater. Alteration of any part of the factory-furnished vent assembly
could result in improper operation due to restriction of flue gases,
spillage of flue gases and may cause carbon monoxide poisoning.
WARNING
1. The appliance and its individual shutoff valve must be discon-
nected from the gas supply piping system during any pressure
testing of the gas system at test pressures in excess of
1
⁄2 pound
per square inch (3.5kPa).
2. The appliance must be isolated from the gas supply piping sys-
tem by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test pres-
sures equal or less than
1
⁄2 pound per square inch (3.5kPa).
WARNING
Soot build-up indicates a problem that requires correction before
further use. Turn “off” gas to water heater and leave “off” until re-
pairs 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.
WARNING
The water heater with vent pipe installed must be properly vented
outdoors. Never operate the water heater unless it is vented to the
outdoors and has adequate air supply to avoid risks of improper
operation, explosion or asphyxiation.
WARNING
Vent termination must not be within 4 feet of any items such as gas
meters, gas valves or other gas regulating equipment.
WARNING
Obstructed or deteriorated vent systems may present a serious
health risk or asphyxiation.
WARNING
Chemical vapor corrosion of the flue and vent system may occur if
air for combustion contains certain chemical vapors. Spray can pro-
pellants, cleaning solvents, refrigerator and air conditioner refrig-
erants, swimming pool chemicals, calcium and sodium chloride,
waxes, bleach, and process chemicals are typical compounds which
are potentially corrosive.
WARNING
Minimum clearances between the water heater and combustible
and non-combustible construction are: 0 inches from sides, 0 inch-
es from back, 5 inches from front of jacket to closet door and 14
inches from top of jacket to combustible and non-combustible
material. Minimum vent clearance: 0 inches. Provide 24 inches
front clearance for servicing and adequate clearance between the
jacket top & ceiling for servicing the flue area.
WARNING
HYDROGEN GAS: Hydrogen gas can be produced in a hot water
system that has not been used for a long period of time (generally
two weeks or more). Hydrogen gas is extremely flammable and
explosive. To prevent the possibility of injury under these condi-
tions, we recommend the hot water faucet be opened for several
minutes at the kitchen sink before any electrical appliances which
are connected to the hot water system are used (such as a dish-
washer or washing machine). If hydrogen gas is present, there will
probably be an unusual sound similar to air escaping through the
pipe as the hot water faucet is opened. There must be no smoking or
open flame near the faucet at the time it is open.
WARNING
INSULATING JACKETS: When installing an external water heater
insulation jacket on a gas water heater:
a. DO NOT cover the temperature-pressure relief valve.
b. DO NOT put insulation over any part of the top of the gas water
heater.
c. DO NOT put insulation over the gas control valve or gas con-
trol valve/burner cover, or any access areas to the burner.
d. DO NOT let insulation around the gas water heater to get with-
in 8 inches of the floor (air must get to the burner).
e. DO NOT remove operating instructions, and safety related warn-
ing labels and materials affixed to the water heater. DO obtain
new warning and instruction labels from the manufacturer for
placement on the jacket directly over the existing labels.
Failure to heed this will result in the possibility of a fire or explosion.
WARNING
Flood damage to a water heater may not be readily visible or imme-
diately detectible. However, over a period of time a flooded water
heater will create dangerous conditions which can cause DEATH,
SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Call a qual-
ified service technician or contractor to replace a flooded water
heater. Do not attempt to repair the unit! It must be replaced!
CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the water
heater must be accomplished in such a manner that if the tank or
any connections should leak, the flow of water will not cause dam-
age to the structure. For this reason, it is not advisable to install the
water heater in an attic or upper floor. When such locations cannot
be avoided, a suitable drain pan should be installed under the water
heater. Drain pans are available at your local hardware store. Such
a drain pan must be not greater than 1
1
⁄2 inches deep, have a mini-
mum length and width of at least 2 inches greater than the water
heater dimensions and must be piped to an adequate drain. The pan
must not restrict combustion air flow.
