10.3 SEMI-ANNUALLY (OR EVERY TWO TONS OF PELLET)

EN
THE FIREBOX BECOMES VERY HOT DURING OPERATION. LET THE APPLIANCE COOL COMPLETELY BEFORE
THE FOLLOWING SECTION DETAILS EXTENSIVE MAINTENANCE PROCEDURES. WE STRONGLY SUGGEST
THESE ITEMS BE CARRIED OUT BY A TRAINED SERVICE TECHNICIAN, POSSIBLY BY A SERVICE AGREEMENT
NOTE: More frequent cleaning may be required depending on pellet quality.
10.3.1 VACUUM HOPPER
The more frequently you clean out the fl y ash, the more effi cient your
appliance will burn.
A. Operate the appliance until the pellets run out, then open the hopper
and vacuum out the entire hopper.
The dust and any other debris near the bottom should be removed to
prevent excessive build-up.
10.3.2

SOOT AND FLY ASH FORMATION

The products of combustion will contain small particles of fl y ash. The fl y ash will collect in the exhaust venting
system and restrict the fl ow of the fl ue gases. Incomplete combustion occurs during startup, shutdown, or
incorrect operation of the room appliance 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.
10.3.3

CLEAN THE VERTICAL EXHAUST DUCT

A. Pivot the viewing door wide open.
B. Remove the one screw on each exhaust port located
on either side of the fi re box. Remove the exhaust port
doors and set aside on a non-combustible surface.
Insert a vacuum into the exhaust port holes and remove as
much fl y ash as possible from behind the left and right exhaust
manifolds. Do not use a household vacuum to clean the
appliance. We recommend that you use a shop vacuum that is
equipped with a fi ne dust fi lter or a vacuum specifi cally made
for ashes and soot. Using a vacuum which is not equipped with
a fi ne dust fi lter may clog and disperse fl y ash and soot into the
room. NOTE: The appliance must be completely out before you vacuum the appliance. Live pellets, if
sucked into the vacuum will light the vacuum on fi re and may ultimately cause a house fi re.
Once clean, replace the exhaust port doors and secure with the screws.
