Check pilot flame pattern and burner flame
patterns often.
pILOT ASSEMBLY
The pilot assembly is factory preset for the
proper flame. Alterations may have occurred
during shipping and handling. The pilot is
located on right hand side of burner.
The flame must envelope 1/4" of top of the
ignitor/sensor and grounding stem.
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 33, page 23). Do not remove the
adjustment screw.
• see Troubleshooting, page 26
BURNER FLAME pATTERN
Burner flames will be steady, not lifting or float-
ing. Flame patterns will be different from unit
to unit and will vary depending on installation
type and weather conditions.
If the vent configuration is installed incorrectly,
flames will lift or "ghost". This can be danger-
ous. Inspect flames after installation to ensure
proper installation and performance.
Figure 36 shows a typical flame pattern.
If burner flame pattern differs from that de-
scribed:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 23)
• see Troubleshooting, page 26
