vented gas log sets to produce moderate
levels of carbon (soot) where flames
contact the logs. This is especially true
with propane/LP gas.)

Note:
The movement and combustion of
gas will create low, unavoidable levels of
noise.)

fireplace and venting professionally
cleaned and checked
3. Separate the logs to allow more flame
passage
