BLOWERS

DANGER
RISK OF ELECTRIC SHOCK. DISCONNECT POWER BEFORE SERVICING UNIT.
Cleaning: Over a period of time, ashes or dust may collect on the blades of both the combustion
blower and convection blower. Periodically the blowers should be vacuumed clean as these
ashes can impede performance. Creosote can also accumulate in the combustion blower (is
accessed by the stove's right side panel). The convection blower is on the left (facing stove).
NOTE: When open, be careful not to dislodge balancing clip on convection blower or to bend
fan blades. Some stove owners lightly spray an anti-creosote chemical on the fire to help reduce
creosote formation within the stove.

CHIMNEY CLEANING

Creosote Formation: When any wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to torm 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 noncombustible,
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 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, detach the vent at the combustion blower transition where it is attached
to the blower.
