6.4 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 Section 6.4: Air Intake Control and Exhaust
Damper).
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 ME300 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.
