CLEANING AND
MAINTENANCE

 WARNING: Turn off heater

and let cool before cleaning.

ODS/PILOT AND BURNER
ORIFICE

• Use a vacuum cleaner, pressurized air,

or small, soft bristled brush to clean.

CLEANING BURNER
PILOT AIR INLET HOLE

We recommend that you clean the unit ev-
ery 2,500 hours of operation or every three
months.

 CAUTION: You must keep

control areas, burner, and circu-
lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a quali-
fied service person. Heater may
need more frequent cleaning due
to excessive lint from carpeting,
bedding material, pet hair, etc.

Figure 21 - Incorrect Burner Flame Pattern

BURNER FLAME PATTERN

Figure 20 shows a correct burner flame
pattern. Figure 21 shows an incorrect burner
flame pattern.

If burner flame pattern is incorrect, as shown
in Figure 21

• turn heater off (see To Turn Off Gas to

Appliance, page 11)

• see Troubleshooting, pages 13 through 15

INSPECTING
BURNER

Check pilot flame pattern and burner flame
pattern often.

PILOT FLAME PATTERN

Figure 18  shows a correct pilot flame pattern.
Figure 19 shows an incorrect pilot flame
pattern. The incorrect pilot flame is not touch-
ing the thermocouple. This will cause the
thermocouple to cool. When the thermo-
couple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown
in Figure 19

• turn heater off (see To Turn Off Gas to

Appliance, page 11)

• see Troubleshooting, pages 13 through 15

Air Passageways

• Use a vacuum cleaner or pressurized air

to clean.

Exterior

• Use a soft cloth dampened with a mild

soap and water mixture. Wipe the cabi-
net to remove dust.

We also recommend that you keep the burner
tube and pilot assembly clean and free of
dust and dirt. To clean these parts we recom-
mend using compressed air no greater than
30 PSI. Your local computer store, hard-
ware store, or home center may carry com-
pressed air in a can. You can use a vacuum
cleaner in the blow position. If using com-
pressed air in a can, please follow the direc-
tions on the can. If you don't follow direc-
tions on the can,  you could damage the pilot
assembly.

1.

Shut off the unit, including the pilot.
Allow the unit to cool for at least thirty
minutes.

2.

Inspect burner, pilot for dust and dirt.

3.

Blow air through the ports/slots and
holes in the burner.

Clean the pilot assembly also. A yellow tip
on the pilot flame indicates dust and dirt in
the pilot assembly. There is a small pilot air
inlet hole about two inches from where the
pilot flame comes out of the pilot assembly
(see Figure 22). With the unit off, lightly
blow air through the air inlet hole. You may
blow through a drinking straw if compressed
air is not available.
