Lennox Hearth MONTAGETM PELLET STOVE 32FS - Manual (Page 3)

CLEANING AND MAINTENANCE SCHEDULE
Maintaining a clean UltraGrate™ is vital to the safe and efficient operation of the stove. It is a good idea to verify
your UltraGrate is clean prior to ignition each time you operate your stove.
DAMPER ADJUSTMENT
The Montage™ pellet stove is equipped with a damper which is used to fine tune combustion. 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, altitude, and maintenance intervals.

IMPORTANT NOTE:
UNPLUG POWER CORD AND ENSURE APPLIANCE IS COLD BEFORE PERFORMING ANY MAINTENANCE WORK.
Above is an example of a pellet
“clinker”. This mass of impurities
can reduce airflow through the
UltraGrate and create an unsafe
burning condition.
Properly cleaned UltraGrate: The
bars running across the bottom are
clean and all the openings are clear.
Dirty UltraGrate: The bars run-
ning across the bottom are not
completely visible. The UltraGrate
should be cleaned.
Opening the damper increases the amount of
combustion air. This can help increase pellet activity
in the UltraGrate™ and correct a dark orange or sooty
flame.
OPENING THE DAMPER
CLOSING THE DAMPER
Closing the damper decreases the amount of
combustion air. This can be a useful adjustment if your
stove is burning out. If the damper is closed too much,
your stove will burn less efficiently and require more
maintenance.
The damper is located behind the right
side door.
REFER TO THE “INSTALLATION AND OPERATION
MANUAL” FOR DETAILED INSTRUCTIONS ON MAKING
ADJUSTMENTS TO THE DAMPER.
