18 MAINTENANCE
CHIMNEY CLEANING
a.
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.
b. Soot and Fly Ash: Formation and Need for Removal - The products of combustion will contain small particles of fly
ash. The fly ash will collect in the exhaust venting system and restrict the flow of the flue 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 or
ton of pellets burned to determine if cleaning is necessary.
c. 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.
RECOMMENDED MAINTENANCE SCHEDULE
Use this as a guide under average-use conditions.

REMOVAL AND REPLACEMENT OF BROKEN DOOR GLASS
While wearing leather gloves (or any other gloves suitable for handling broken glass), carefully remove any loose pieces of
glass from the doorframe. Dispose of all broken glass properly. Return the damaged door to your US Stove Dealer for repair
or replacement.
Neither the appliance owner nor any other unauthorized person(s) should replace the door glass. An authorized US Stove
dealer must perform all repairs involving door glass.
