d. Glass too loose and
air tight packet leaks in
corners after usage
Tighten the corner.
e. Bad thermopile or

6. Glass soots.
a. Flame impingement
Adjust the log set so that the fl ame does not excessively impinge on it.
b. Improper venturi setting
Adjust the air shutter at the base of the burner.
c. Debris around venturi
Inspect the opening at the base of the burner. NO MATERIAL SHOULD BE
PLACED IN THIS OPENING.
7. Flame burns
