l Use a vacuum cleaner or

pressurized air to clean.

l Use a soft cloth dampened with

a mild soap and water mixture.

Wipe the cabinet to remove dust.

WARNING: If yellow tipping

occurs, your heater could produce

increased levels of carbon

monoxide. If burner flame pattern

shows yellow tipping, follow instruc-

tions at bottom of this page.

Notice: Do not mistake orange

flames with yellow tipping. Dirt or

other fine particles enter the heater

and burn causing brief

patches of orange flame.

PILOT FLAME PATTERN

Figure 20 shows a correct pilot

flame pattern. Figure 21 shows an

incorrect pilot flame pattern. The

incorrect pilot flame is not touching

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 21.

l turn heater off (see To Turn Off

Gas to Appliance on page 11

for non-thermostat models or

page 12 for thermostat models.)

l see Troubleshooting. pages 14

through 16.

WARNING: Turn off heater

and let cool before servicing.

CAUTION: You must keep con-

trol

areas, burner, and circulating

air passageways of heater clean.

Inspect these areas of heater

before each use. Have heater

inspected yearly by a qualified

service person. Heater may need

more frequent cleaning due to

excessive lint from carpeting,

bedding material, pet hair, etc.

CLEANING AND

MAINTENANCE

nINSPECTING BURNERn

Check pilot flame pattern and

burner flame pattern often.

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 PSl. 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 and pilot for dust

and dirt.

3. Blow air through the ports/slots

and holes in the burner.

Also clean the pilot assembly. A

yellow tip on the pilot flame indi-

cates 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 24).

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.
