INSPECTING BURNER
Check pilot flame pattern and burner flame pat- terns often.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pattern. Figure 24 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 heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 24
•turn heater off (see To Turn Off Gas to Appli- ance, page 17)
•see Troubleshooting, page 22
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.

If burner flame pattern is incorrect, as shown in Figure 26
•turn heater off (see To Turn Off Gas to Appli- ance, page 17)
•see Troubleshooting, page 22
The flames from the burner travel horizontally through the log set and emerge at the middle and rear of the set against the back logs.
The flames are blue off the burner and as they progress through the log set, change to a light yellow color, yellow decorative flames are visible as the flames exit the log set.
The base of the log set and the underside of the top logs glow red. Natural gas models will burn with more blue flame, while propane gas model will burn with bright yellow flame.

BURNER FLAME PATTERN
Figure 25 shows correct burner flame pattern.
NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by heater, causing brief patches of orange flame.
