cover out of the slot on the left.This will expose the
combustionblowerwheelandueoutlet,Fig.27.
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yashandsoot.Using a vacuum which is not
equipped with a ne dust lter may clog and dis-
perse y ash and soot into the room.
NOTE: THE STOVE MUST BE COMPLETELY OUT
BEFORE YOU VACUUM THE STOVE. LIVE PEL-
LETS, IF SUCKED INTO THE VACUUM WILL LIGHT
THE VACUUM ON FIRE AND MAY ULTIMATELY
CAUSE A HOUSE FIRE.

Soot and Fly Ash
Formation and Need for Removal- The products of
combustionwillcontainsmallparticlesofyash.They
ash 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 opera-
tion of the room heater will lead to some soot formation
which will collect in the exhaust venting system. The
stove should be cleaned after each ton of pellets (50
bags) and the venting system inspected and cleaned
yearly, after each heating season.
