Maintenance

 Failure to clean and maintain this unit as indicated can result in poor performance and safety hazards.
 unplug your stove's electrical cord prior to removing the back panel or opening the exhaust system for any
inspection, cleaning, or maintenance work.
 Never perform any inspections, cleaning, or maintenance on a hot stove.
 Do not operate stove with broken glass , leakage of flue gas may result.

ExhAuST SySTEm

Creosote Formation – When any wood is burned slowly, it produces tar and other organic vapors, which combine with
expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue or a newly started
fire or from a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote
makes an extremely hot fire, which may damage the chimney or even destroy the house. Despite their high efficiency,
pellet stoves can accumulate creosote under certain conditions.
Fly Ash – This accumulates in the horizontal portion of an exhaust run. Though non-combustible, it may impede the
normal exhaust flow. It should therefore be periodically removed.
Inspection and Removal – The chimney connector and chimney should be inspected annually or per ton of pellets to
determine if a creosote or fly ash build-up has occurred. If creosote has accumulated, it should be removed to reduce
the risk of a chimney fire. Inspect the system at the stove connection and at the chimney top. Cooler surfaces tend to
build creosote deposits quicker, so it is important to check the chimney from the top as well as from the bottom. The
creosote should be removed with a brush specifically designed for the type of chimney in use. A qualified chimney sweep
can perform this service. It is also recommended that before each heating season the entire system be professionally
inspected, cleaned and, if necessary, repaired. To clean the chimney, disconnect the vent from the stove.

iNTEriOr ChAmBErS

Periodically remove and clean the burn pot and the area inside the burn pot housing. In particular it is advisable to
clean out the holes in the burn pot to remove any build up that may prevent air from moving through the burn pot freely.
Remove the two(2) plates on each side of the burn pot housing and clean out that rear chamber.
If a vacuum is used to clean your stove, we suggest using a vacuum designed for ash removal. Some regular vacuum
cleaner (i.e. shop vacs) may leak ash into the room.

ASh DiSPOSAL

Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on
a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes
are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all
cinders have been thoroughly cooled. The container shall not be used for other trash or waste disposal.

ChECK AND CLEAN ThE hOPPEr

Check the hopper periodically to determine if there is any sawdust or pellets that are sticking to the hopper surface.
Clean as needed.
DOOr AND gLASS gASKETS
Inspect the main door and glass window gaskets periodically. The main door may need to be removed to have frayed,
broken, or compacted gaskets replaced by your authorized dealer. The glass gasket has a gap at the bottom for the
airwash.

BLOWEr mOTOrS

Clean the air holes on the motors of both the exhaust and distribution blowers annually. Remove the exhaust blower
from the exhaust duct and clean out the internal fan blades as part of your fall start-up.

PAiNTED SurFACES

Painted surfaces may be wiped down with a damp cloth. If scratches appear, or you wish to renew your paint, contact
your authorized dealer to obtain a can of suitable high-temperature paint.
