DAMPER ADJUSTMENT

The Winslow™ PI40 pellet fireplace insert is equipped with a damper adjustment which is used to fine tune com-
bustion. Although every unit is test burned and calibrated at the factory, periodic adjustment may be necessary at
times to compensate for variables such as fuel, venting, climate, altitude, and maintenance intervals.
OPENING THE DAMPER
Opening the damper increases the amount of
combustion air. This can help increase pellet activity in
the burn pot and correct a dark orange or sooty flame.
CLOSING THE DAMPER
Closing the damper decreases the amount of combus-
tion air. This can be a useful adjustment if your fire-
place insert is burning out. However, if the damper is
closed too much, your fireplace insert will burn less
efficiently and require more maintenance.
REFER TO THE "INSTALLATION AND OPERATION
MANUAL" FOR DETAILED INSTRUCTIONS ON MAKING
ADJUSTMENTS TO THE DAMPER.

CLEANING AND MAINTENANCE SCHEDULE
Maintaining a clean burn pot is vital to the safe and efficient operation of the fireplace insert. It is a good idea to
verify your burn pot is clean prior to ignition each time you operate your fireplace insert.
Properly cleaned burn pot: The
holes in the bottom and sides are
clean and all the openings are clear.
IMPORTANT NOTE:
UNPLUG POWER CORD AND ENSURE APPLIANCE IS COLD BEFORE PERFORMING ANY MAINTENANCE WORK.
The damper is located inside the right door.
Dirty burn pot: The holes in the bot-
tom and sides are not completely
visible. The burn pot should be
cleaned.
Above is an example of a pellet
"clinker". This mass of impurities
can reduce airflow through the burn
pot and create an unsafe burning
condition.
