Air Intake Control and Exhaust Damper

The air intake control (dilution air) and exhaust damper should be in the closed position when
there has not been any wood or embers in the fireplace for a few hours. This will minimize air
leakage up the chimney.

6.5 Smoking Causes and Troubleshooting
Your fireplace has been designed and tested to provide smoke free operation. Occasionally,
there may be a small amount of smoking upon lighting the fire, until the chimney heats up but
this should not continue. If the fireplace continues to smoke it is probably for one of the
following reasons:
A. Closed exhaust damper
Make sure that the exhaust damper is in the open position (see Figure 39).
B. Negative pressure in the house
As the fire burns, air goes up the chimney. This air must be replaced through leakage into
the house or through the fresh air kit. When operating the FP7CB ANTOINETTE WOOD
FIREPLACE, open a nearby window temporarily to check if there is adequate air supply
replacement. If opening a window solves the problem, the house is under negative pressure.
C. Wet wood
Wet or tarred wood will smoulder and smoke instead of burning properly.
