INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 40 shows a correct pilot flame pat- tern. Figure 41 shows an incorrect pilot flame pattern. The incorrect pilot flame is not properly heating the thermocouple. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 41.

•turn heater off (see To Turn Off Gas to Appliance, page 19)

•see Troubleshooting, pages 22 through 24

BURNER FLAME PATTERN

Figure 42 shows a correct burner flame pattern. Figure 43 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than one inch above the log.

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

WARNING: If yellow tipping occurs, your fireplace could pro- duce increased levels of carbon monoxide. If burner flame pat- tern shows yellow tipping, follow instructions in column 3.

NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the fireplace and burn causing brief patches of orange flame.

If burner flame pattern is incorrect, as shown in Figure 43.
