WARNING
This water heater must not be 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 (76.2mm) 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 a fire hazard.
WARNING
Do not install in a confined area such as a closet, unless you provide
ventilation 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 company. Failure to provide
ventilation air can result in a fire or explosion and can cause
DEATH, SERIOUS BODILY 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 clean-
ing 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 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 direct vent water heater requires its own (separate)
venting system. It cannot be connected to an existing vent pipe
or chimney. It must be terminated to the outdoors. Failure to
properly install the venting system can result in asphyxiation, a
fire or explosion and can cause DEATH, SERIOUS BODILY IN-
JURY, 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 dis-
connected from the gas supply piping system during any pres-
sure 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
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).
WARNING
Soot build-up indicates a problem that requires correction be-
fore 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, SE-
RIOUS BODILY INJURY, OR PROPERTY DAMAGE.
WARNING
The water heater must be properly vented outdoors. Never op-
erate the water heater unless it is vented to the outdoors and
has adequate air supply to avoid risks of improper operation, ex-
plosion 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
propellants, cleaning solvents, refrigerator and air conditioner
refrigerants, swimming pool chemicals, calcium and sodium chlo-
ride, 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, 6 inches from front of jacket to closet door and 12
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 and 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 control
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 (access for servicing 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 connec-
tions should leak, the flow of water will not cause damage 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 have a minimum length
and width of at least 2 inches greater than the water heater dimensions
and must be piped to an adequate drain. Drain pan depth must allow for
access to the outer doors for servicing the ignitor and burner.
