OBSERVED PROBLEM
Log set is smoking/sooting
excessively

able for vented gas log sets to
produce moderate levels of car-
bon (soot) where flames contact
the logs. This is especially true
with propane/LP gas.)
Burner is excessively noisy
(Note: The movement and com-
bustion of gas will create low,
unavoidable levels of noise.)
Burner flames are too low or
too high
