General Safety
WARNING
This water heater must not be installed directly on carpetini
appliance l
appliance I
be covered by the pane!, failure to heed this warning may result
in a fire hazard.
WARNING
A gas water heater cannot operate properly vyithout 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 ven­
tilation air. If you have any doubts or questions at all, call your
proper
expii
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 beater or water
heaters oe 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.
WARNING
VENT I
mally
drafting of the water beater.
Thermally Operated Vent Dampers: Gas-fired water heaters hav­
ing 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 monox­
ide poisoning.
Vent dampers must bear evidence of certification as complying
with the btest edition of American National Standard ANSI
Z2I.68 (ANSI Z21.66 & 67, respectively, cover electrically and
mechanically actuated vent dampers). Before installation of any
vent damper, consult your local Sears Service Center or the gas
utility for further information.
WARNING
1. The appliance and its individual shutoff valve most be discon­
nected from the gas supply piping system during any pressure
testing of the gas system at test pressures in excess of
'h
pouftcfper square inch (3.5kPa).
2. The appliance must be isolated from the gas supply piping sys­
tem by dosing its individual manual shutoff valve during any
WARNING
Soot buitd-up indicates a problem that requires correction before
furtlser use. Turn "OFF" gas to water heater and leave "OFF"
until repairs are made, because failure to correct the саше of the
sooting can result in a fire or explosion causing DEATH, SERI­
OUS BODILY INJURY, OR PROPERTY DAMAGE.
WARNING
The water heater with draft hood installed must be properly
vented to a chimney which terminates outdoors. Never operate
the water heater unless it is vented to the outdoors and has ade­
quate air supply to avoid risks of improper operation, explosion
or asphyxiation.
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
chionde, waxes, bleach, and process chemicals are typical com­
pounds which are potentially corrosive.
WARNING
Minimum clearances between the water heater and combustible
construction are T' at the sides and rear, 4" at the front, and 6"
from the vent pipe. Clearance from the top of the jacket is 18"
on most models. Note that a lesser dimension may be allowed
on some models. Gas water heaters acceptable for use on com­
bustible floors in an alcove or closet. Refer to the label on the
water heater adjacent to the gas control valve for all clearances.
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 not water faucet be opened for severa!
minutes at the kitchen sink before any eléctrica! 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 healer:
a, DO NOT cover tlie temperature-pressure relief vaive.
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/bumer cover, or any access areas to the burner.
d, DO NOT let insulation around tire gas water healer to get
within 8 inches of the floor (air must get to the burner).
e, DO NOT cover or remove operating instructions, and safety
related warning labels and materials affixed to the water
healer.
Failure to heed this will result in the possibility of a fire or
explosion.
WARNING
Do not use this appliance if any part of it has been under water.
Immediately call a Sears Service Technician to inspect the appli­
ance and to replace the gas control or any part of the burner sys­
tem which has been under water.
CAUTION
WATER HEATERS EVENTUALLY LEAK: Inslailation of the water
heater must be accomplished in such a manner that jf the tank or
any connections should leak, the flow of water will not cause
damage to the structure. When such locations cannot be avoid­
ed, a suitable drain pan should be Installed under the water
heater. Drain pans are available at your local Sears store. Such a
drain pan must be not greater than
Vh inches deep, have a mini­
mum length and width of at least 2 inches greater than the water
lieater dimensions and must be piped to an adequate drain. The
pan must not restrict combustion air flow. Under no circum­
stances is the manufacturer or Sears to be held liable for any
water damage in connection with this water heater.
