BURNER FLAME PATTERNS

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

WARNING: Turn off heater and let cool before cleaning. WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If burner flame patterns show yellow tipping, follow in- structions 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.

If front and/or middle burner flame patterns are incorrect, as shown in Figure 44

•turn heater off (see To Turn Off Gas to Appliance, pages 19 or 20

CLEANING AND

MAINTENANCE

CLEANING BURNER INJECTOR HOLDERS AND PILOT AIR INLET HOLES WARNING: Turn off heater and let cool before cleaning.

Manual background CAUTION: You must keep control areas, burners, and circulating air passageways of heater clean. In- spect these areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent cleaning due to exces- sive lint from carpeting, pet hair, bedding material, etc.

CLEANING 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 com- pressed air in a can. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the direc- tions on the can. If you don't follow directions on the can, you could damage the pilot assembly.
