Proper Primary Airflow into Burner
For proper burner operation and flame appearance, the flow of
primary air into the venturi tube, located on the rear of the burner,
must not be reduced. This flow of air is reduced if dirt, lint or other
obstructions build-up around or inside the venturi. Any obstruction
in the venturi tube area must be removed. The flow of air into the
venturi is also reduced if the gas orifice isn’t centered in the venturi
inlet and/or is not aligned with the venturi. Any misalignment of the
burner orifice may be corrected by bending the shutter cap holding
the orifice to the inlet of the venturi tube.
Ceiling Fans, Portable Fans or Logs Installed Near Cold Air
Returns
Ceiling fans or oscillating floor type fans need to be monitored
during the operation of vent-free appliance. If the air blows directly
into the flame causing it to disrupt the flame, it should be turned off
or redirected. Ceiling fans could be reversed to possibly eliminate
flame impingement, and the floor fan should be redirected. Upon
installation, be aware of any cold air returns or vents in the
proximity of the log set. Any draft created around a vent-free log
set can cause the flame to impinge on the log and create a sooting
situation.
WARNING
Do not allow fans to blow directly into the fireplace. Avoid any
drafts that alter burner flame patterns.
Candles
Avoid the use of scented or decorative candles while the log set is
in operation. Candles produce a residue in the air that creates a
soot like substance. Burning candles while the log set is operating
magnifies the problem. It should be noted that candles, in general,
produce soot. The amount of time burned and the quantity of
candles burned will determine the amount of soot produced and
deposited.
