INSPECTING

BURNER

Check pilot flame pattern and burner flame

pattern often.

PILOT FLAME PATTERN

Figure 19 shows a correct pilot flame pattern.

Figure 20 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 20

• turn heater off (see To Turn Off Gas to

Appliance, page 12)

• see Troubleshooting, pages 14 through 16

CLEANING AND

MAINTENANCE

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.

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 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.

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.
