At least once a year a visual inspection should be made of the main burner 
and the hot surface igniter assembly for proper fl ame  characteristics 
and ignition sequences. This can be done by removing the Outer Door 
and viewing the main burner operation through the Viewport on the 
Inner Door, see Figure 1. The main burner should provide complete 
combustion of gas, ignite rapidly, give reasonably quiet operation, and 
cause no excessive fl ame lifting from the burner ports. If the proper fl ame 
characteristics are not evident (see Figure 28), make sure that the fl ow 
of combustion and ventilation air is not blocked on the Air Intake Screen 
at the base of the water heater (see Figure 29), the Lint screen on the 
blower assembly (see Figure 1), and in the venting system.
  
You should also check for sooting. Soot is not normal and will impair 
proper combustion. A visual inspection of the main burner and HSI 
igniter assembly should also be done at least once a year, see 
Figure 28.
Soot build-up indicates a problem that requires correction before 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 fi re 
causing death, serious injury, or property damage.

BURNER CLEANING
In the event your burner or burner air openings require cleaning, turn 
the blower switch to the “OFF” position and allow the burner to cool. Call 
Sears Service Center to remove and clean the burner and correct the 
problem that required the burner to be cleaned.
HOUSEKEEPING
Vacuum around base of water heater for dust, dirt, and lint on a regular basis.
This water heater unit is supplied with a plastic Air Intake Screen that 
will fi lter and prevent lint build-up on the bottom of the fl ame arrestor of 
this heater. To prevent the lint build-up on the arrestor, the lint screen 
must be installed on the Base Pan with the “arrows” pointing upwards as 
shown in Figure 29. If the Air Intake Screen is missing from this heater, 
please contact Sears Service Center for a replacement part.

AT LEAST ONCE EVERY SIX MONTHS A VISUAL INSPECTION 
SHOULD BE MADE OF THE AIR INTAKE SCREENS ON THE BASE 
OF THE WATER HEATER AND THE BLOWER ASSEMBLY. CLEAN 
IF LINT ACCUMULATIONS ARE NOTICED.
INSTALLED IN SUITABLE AREA: To insure suffi cient 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 fl ammable 
liquids, etc. must not be placed against or adjacent to the water heater 
which can cause a fi re.
ANODE ROD INSPECTION
The anode rod is used to protect the tank from corrosion.  Most hot water 
tanks are equipped with an anode rod.  The submerged rod sacrifi ces 
itself 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 
a qualifi ed technician, and at a minimum should be checked annually 
after the warranty period.
TEMPERATURE-PRESSURE 
RELIEF VALVE OPERATION
                      
The temperature-pressure relief valve must be manually operated at 
least once a year.
