Inner vent pipe leaking exhaust
gases back into the system.
Check venting system for damage. Replace/repair improperly
assembled pipe sections.
D
.
Glass installed improperly.
Check to ensure glass is installed properly. Replace glass panel

Flame impingement.
Adjust the log set so that the flame does not excessively impinge on
it. Refer to log instructions.
B
.
Improper air shutter setting.
Refer to manual for shutter set points. Ensure that set point is correct
for appliance/gas type. If unit has adjustable shutter, it may be
necessary to increase shutter opening.
C
.
Debris around air shutter.
Inspect the opening at the base of the burner. NO MATERIAL
SHOULD BE PLACED IN THIS OPENING.

.
Flame burns blue and lifts
off burner.
A
.
Insufficient oxygen being
supplied.
Ensure that the vent cap is installed properly and free of debris.
Ensure that the vent system joints are tight and have no leaks.
Ensure that no debris has been placed at the base of, or in the area
of the air holes in the center of the base pan beneath the burner.
