Figure 43 shows correct front and/or middle burner flame patterns. Figure 44 shows incorrect front and/or middle burner flame patterns. The incorrect burner flame patterns show yellow tipping at top of blue flame.

WARNING: If yellow tipping occurs, your heater could pro- duce increased levels of carbon monoxide. If burner flame pat- terns show yellow tipping, follow instructions below.Yellow flame on rear burner is normal.

NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by heater, causing brief patches of orange flame.

CLEANING AND

MAINTENANCE

WARNING: Turn off heater

and let cool before cleaning.

CAUTION: You must keep

control areas,

burners, 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, pet hair, bedding

material, etc.

 

WARNING: Failure to keep

the primary air opening(s) of

the burner(s) clean may result in

sooting and property damage.

BURNER INJECTOR HOLDERS AND

PILOT AIR INLET HOLES

The primary air inlet holes allow the proper amount

of air to mix with the gas. This provides a clean

burning flame. Keep these holes clear of dust, dirt,

lint, and pet hair. Clean these air inlet holes prior to

each heating season. Blocked air holes will create

soot. We recommend that you clean the unit every

three months during operation and have heater

inspected yearly by a qualified service person.

We also recommend that you keep the burner

tubes 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 com-

pressed air in a can, please follow the directions on

the can. If you donʼt 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 burners, pilot, and primary air inlet holes on injector holder for dust and dirt (see Figures 45 and 46, page 26).
