INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT ASSEMBLY
The pilot assembly is factory preset for the proper flame height.
Alterations may have occurred during shipping and handling. The
pilot is located on the back right hand side of the burner.
The thermocouple should be fully enveloped in the flame. The flame
should not be lifting off of the thermocouple element.
If your pilot assembly does not meet these requirements:
• Turn the adjustment screw marked pilot clockwise to decrease
or counterclockwise to increase the flame to proper size (see
Figure 20). Do not remove the adjustment screw.
• see Troubleshooting, pages 13 through 15

Figure 21 - Typical Flame Pattern
BURNER FLAME PATTERN
Burner flames will be steady; not lifting or floating. Flames should
go up through the middle of logset. Flames should not "spill" to the
edges of the pan or sides of the logset.
Figure 21 shows a typical flame pattern. If burner flame pattern differs
from that described:
• turn appliance off (see To Turn Off Gas to Appliance, page 11)
• see Troubleshooting, pages 13 through 15
