8. Clean the combustion blower wheel with a brush and
a vacuum cleaner. Note: Do not use a household
vacuum to clean the stove. We recommend that
youuseashopvacuumthatisequippedwithane
dustltercalledaHEPAlteroravacuumspecially
made for ashes and soot. Using a vacuum which is
not equipped with a ne dust lter may clog and
disperse y ash and soot into the room.
NOTE: THE STOVE MUST BE COMPLETELY
OUT BEFORE YOU VACUUM THE STOVE. LIVE
PELLETS, IF SUCKED INTO THE VACUUM

Soot and Fly Ash
Formation and Need for Removal - The products
of combustionwill containsmall particlesof yash.
Theyashwillcollectintheexhaustventingsystem
and restrictthe owof theue gases.Incomplete
combustion, such as occurs during startup, shutdown,
or incorrect operation of the room heater will lead to
some soot formation which will collect in the exhaust
venting system. The exhaust venting system should
be inspected at least once every year to determine
if cleaning is necessary.
Removing fly ash and soot improves efficiency
andinsuresthattheueventingpassagewayisclear
and unobstructed. The stove should be cleaned after
each ton of pellets (50 bags) and the venting system
inspected and cleaned after each heating season.
