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.

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 Breckwell Dealer for repair or replacement. 
 
Neither the appliance owner nor any other unauthorized person(s) should replace the door glass. An authorized 
Breckwell dealer must perform all repairs involving door glass.
