Housekeeping
Temperature-Pressure Relief Valve Operation
Vacuum around base of water heater for dust, dirt, and lint on a
regular basis.
^DANGER
Fire and Explosion Hazard
Do not obstruct combustion air
openings at the bottom of the
water heater.
Do not use or store flammable
vapor products such as gasoline,
solvents
or
adhesives
in
the
same room or area near water
heater or other appliance.
Visibly inspect air intake screen
at least once every six months
and dean if accumulated lint.
Can
cause
serious
injury
or
death.
AT LEAST ONCE EVERY SIX MONTHS A VISUAL
INSPECTION SHOULD BE MADE OF THE AIR
INTAKE
SCREEN.
CLEAN
IF
LINT
ACCUMULATIONS ARE NOTICED.
INSTALLED IN SUITABLE AREA: To insure sufficient ventilation
and combustion air supply, proper clearances from the water
heater must be maintained.
See Facts to Consider About the
Location
section.
Combustible
materials
such
as
clothing,
cleaning
materials,
or
flammable
liquids,
etc.
must
not
be
placed against or adjacent to the water heater because they
could catch on fire.
Anode Rod Inspection
CAUTION
Property Damage Hazard
’ Avoid water heater damage.
' Inspection and replacement of anode rod required.
The anode rod is used to protect the tank from corrosion. Most
hot
water
tanks
are
equipped
with
an
anode
rod.
The
submerged
rod
deteriorates
to
protect
the
tank.
Instead
of
corroding the tank, water ions attack and eat away the anode
rod. This does not affect the water’s taste or color. The rod
must be maintained to keep the tank in operating condition.
Anode
deterioration
depends
on
water
conductivity,
not
necessarily water condition. A corroded or pitted anode rod
indicates high water conductivity and should be checked and/
or replaced more often than an anode rod that appears to be
intact. Replacement of a depleted anode rod can extend the
life of your water heater. Inspection should be conducted by
calling the Sears Service Center for an authorized contractor.
At a minimum, the anode(s) should be checked annually after
the warranty period.
The
temperature-pressure
relief
valve
must
be
manually
operated at least once a year.
When checking the temperature-pressure relief valve operation,
make sure that (1 ) no one is in front of or around the outlet of
the temperature-pressure relief valve discharge line, and (2) that
the water discharge will not cause any property damage, as the
water may be extremely hot, see Figure 24.
If after manually operating the valve, it fails to completely
reset and continues to release water, immediately close the
cold
water
inlet
to
the
wafer
heater,
follow
the
draining
instructions,
and
replace
the
temperature-pressure
relief
valve
with a new one.
If the temperature-pressure relief valve on the appliance weeps
or
discharges
periodically,
this
may
be
due
to
thermal
expansion. You may have a check valve installed in the water
line or a water meter with a check valve. Consult the Sears
Service
Center
for
further
information.
Do
not
plug
the
temperature-pressure relief valve.
Draining
The water heater should be drained if being shut down during
freezing temperatures. Also periodic draining and cleaning of
sediment from the tank may be necessary.
