OBSERVED PROBLEM
Log set is smoking/sooting
excessively

avoidable for vented gas log
sets to produce moderate

flames contact the logs. This
is especially true with propane/
LP gas.)
Burner is excessively noisy
(Note: The movement and
combustion of gas will cre-
ate low, unavoidable levels
of noise.)
Burner flame is too low or
too high
