INSPECTING
BURNER

Check pilot flame pattern and burner flame
pattern often.

PILOT FLAME PATTERN

Figure 19 shows a correct pilot flame pat-
tern. Figure 20 shows an incorrect pilot
flame pattern. The incorrect pilot flame is
not touching the thermocouple. This will
cause the thermocouple to cool. When the
thermocouple cools, the heater will shut
down.

If pilot flame pattern is incorrect, as shown
in Figure 20

• turn heater off (see To Turn Off Gas to

Appliance, page 11)

• see Troubleshooting, pages 13 through 15

BURNER FLAME PATTERN

Figure 21 shows a correct burner flame
pattern. Figure 22 shows an incorrect burner
flame pattern.

If burner flame pattern is incorrect, as shown
in Figure 22

• turn heater off (see To Turn Off Gas to

Appliance, page 11)

• see Troubleshooting, pages 13 through 15

CLEANING AND
MAINTENANCE

ODS/PILOT AND BURNER
ORIFICE

• Use a vacuum cleaner, pressurized air,

or small, soft bristled brush to clean.

 WARNING: Turn off heater

and let cool before cleaning.

 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.

CABINET

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.

CLEANING BURNER
PILOT AIR INLET HOLE

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

We also recommend that you keep the burner
tube and pilot assembly clean and free of dust
and dirt. To clean these parts we recommend
using compressed air no greater than 30 PSI.
Your local computer store, hardware store, or
home center may carry compressed air in a
can. You can use a vacuum cleaner in the
blow position. If using compressed air in a
can, please follow the directions on the can.
If you don't follow directions 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 23). 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.
