STRANGE
SOUNDS
Possible noises due toexpansion
and contraction
ofsome m etal parts
during periods ofheat-up and cool-down
donot n ecessarily
represent
harmful ordangerous
conditions.
Condensation
causes sizzling and popping
within the burner area d uring
heating and cooling periods and should b econsidered
normal. See
"Condensate"
inthis section.
OPERATIONAL
CONDITIONS
SMELLY WATER
In each water heater there is installed at least one anode rod (see parts
section) for corrosion protection of the tank. Certain water conditions
will cause a reaction between this rod and the water. The most common
complaint associated
with the anode rod is one of a "rotten egg smell"
in the hot water. The smell is a result of four factors which must all be
present for the odor to develop:
a. A concentration
of sulfate in the supply water.
b. Little or no dissolved oxygen in the water.
c. A sulfate reducing bacteria which has accumulated within the water
heater (this harmless bacteria is nontoxic to humans).
d. An excess of active hydrogen
in the tank. This is caused by the
corrosion protective action of the anode.
Smelly water may be eliminated or reduced in some water heater models
by replacing the anode(s) with one of less active material, and then
chlorinating
the water heater tank and all water lines. Contact Sears
Service Center for further information
concerning Anode Replacement
Kit #9001453 and this chlorination
treatment. Anode replacement
and
chlorination
of the tank are not covered by the water heater's limited
warranty.
If the smelly water persists after the anode replacement and chlorination
treatment, we can only suggest that chlorination or aeration of the water
supply be considered
to eliminate the water problem.
Do not remove
the anode leaving
the tank unprotected.
By doing
so, all warranty
on the water heater tank is voided.
"AIR"
IN HOT WATER
FAUCETS
/
Explosion
Hazard
• Flammable hydrogen gases may be present.
• Keep all ignition sources away from faucet
when turning on hot water.
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 conditions,
we recommend
the hot water
faucet,
located
farthest
away, be
opened
for several
minutes
before
any electrical
appliances
which are connected
to the hot water system
are used (such as a
dishwasher
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.
HIGH WATER
TEMPERATURE
SHUT OFF SYSTEM
This water heater is equipped with an automatic
gas shut-off system.
This system works when high water temperatures
are present. Turn
"OFF" the entire gas supply to the water heater. The high temperature
shut-off
is built into the gas control valve. It is non-resettable.
If the
high temperature
shut-off
activates,
the gas control valve must be
replaced.
Contact
your gas supplier
or Sears Service
Center.
VENTING
SYSTEM
INSPECTION
• Flue gases may escape if vent pipe is
not connected.
• Be
alert
for
obstructed,
sooted
or
deteriorated
vent
system
to
avoid
serious injury or death.
• Do not store
corrosive
chemicals
in
vicinity of water heater.
• Chemical
corrosion
of flue and vent
system
can cause
serious
injury
or
death.
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
At least once a year a visual inspection should be made of the venting
system.
You should look for:
1. Obstructions
which could cause improper venting.
The combustion
and ventilation
air flow must not be obstructed.
2. Damage
or deterioration
which could cause improper
venting or
leakage of combustion products.
Be sure the vent piping is properly
connected
to prevent escape of
dangerous flue gasses which could cause deadly asphyxiation.
Obstructions and deteriorated
vent systems may present serious health
risk or asphyxiation.
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 chloride, waxes, bleach and process
chemicals are typical compounds which are potentially corrosive.
If after inspection of the vent system you found sooting or deterioration,
something
is wrong. Call the local gas utility to correct the problem and
clean or replace the flue and venting before resuming operation of the
water heater.
BURNER OPERATION AND INSPECTION
26
Flood damage to a water heater may not be readily visible or immediately
detectable.
However, over a period of time a flooded water heater will
create
dangerous
conditions
which can cause DEATH, SERIOUS
BODILY INJURY, OR PROPERTY
DAMAGE.
Contact Sears Service
Center to replace a flooded water heater. Do not attempt to repair the
unit! It must be replaced!
