INSPECTING BURNER
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 16 shows a correct pilot flame pattern. Figure 17 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the appliance will shut down.
If pilot flame pattern is incorrect, as shown in Figure 17
•turn appliance off (see To Turn Off Gas to Appliance, page 12
•see Troubleshooting, pages 14 through 16
Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.

BURNER FLAME PATTERN
Figure 18 shows correct burner flame pattern.
NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by ap- pliance, causing brief patches of orange flame.
If burner flame pattern is incorrect, as shown in Figure 19
•turn appliance off (see To Turn Off Gas to Appliance, page 12
•see Troubleshooting, pages 14 through 16

CLEANING AND MAINTENANCE
•Keep the area around the log set clean and clear of debris.
•Periodically inspect the air mixer and burner tube for foreign matter blocking the air inlet and flame holes.
•Once every year a qualified agency or certified chimney sweep should examine and clean the venting system of the fireplace.
