BURNER FLAME PATTERN

Figure 43 shows a correct burner flame pattern. Figure 44 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows sporadic, irregular flame tip- ping. It also shows the flame consistently higher than one inch above the log.

Note: When using the fireplace the first time, the flame will be orange for approxi- mately one hour until the log cures.

If burner flame pattern is incorrect, as shown in Figure 44

turn fireplace off (seeTo Turn Off Gas to Appliance, page 18)

CLEANING AND MAINTENANCE

WARNING: Turn off fireplace and let cool before cleaning.

CAUTION: You must keep con- trol areas, burner, and circulating air passageways of fireplace clean. Inspect these areas of fireplace before each use. Have fireplace inspected yearly by a qualified service person. Fireplace may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE

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 cre- ate soot. We recommend that you clean the unit every three months during operation and have heater inspected yearly by a quali- fied service person.

We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recom- mend using compressed air no greater than 30 PSI. Your local computer store, hard- ware store, or home center may carry com- pressed 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 direc- tions on the can. If you don't follow direc- tions 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, and primary air inlet holes on injector holder for dust and dirt (see Figure 45).

3.Blow air through the ports/slots and holes in the burner.

4.Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle.

5.Blow air into the primary air holes on the injector holder.

6.In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4.

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 46). 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.
