MAINTAINING YOUR OSBURN STRATFORD
3.3.1 Creosote
When wood is burned slowly without a flame, it produces tar and other organic vapours
which combine with expelled moisture to form a black deposit called creosote. Creosote
accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire. If the
creosote accumulation is large, a creosote fire in the chimney can damage the chimney and
overheat the surrounding wood framing. Creosote formation in a chimney can be minimized
by making sure there is always visible flame burning, avoid smouldering fires and by proper
refueling techniques.
3.2.2 Chimney Maintenance
Regular chimney inspection and maintenance combined with proper operation will prevent
chimney fires. Keep your chimney clean. Do not allow more than 1/16
″
creosote build up in
your chimney. The amount of creosote will depend on variables such as frequency of use and
type of fire. We recommend that you:
A. Initially inspect the chimney system weekly. From this, you will learn how often it
will be necessary to clean your chimney.
B. Have your chimney cleaned by a qualified chimney sweep. If you wish to clean it
yourself, we recommend using a stiff plastic or non-metallic brush. If a metal brush is
used, its size should be slightly smaller than the flue to avoid damaging the chimney.
Do not use a brush that will scratch the stainless steel interior of the chimney.
C. Do not expect chemical cleaners to keep your chimney clean. The rain cap can be
removed for inspection and/or cleaning of the chimney.
3.3.3 Top Baffle Removal Prior to Cleaning the Chimney
Before starting to clean your chimney, we recommend that you remove the top baffle to avoid
creosote dust collection at the top of the baffle. Follow these steps to set the top baffle out of
the way:
1. Remove the front air tube by pulling out the cutter pin on the side of the tube. They are
located at the top, underneath the baffle.
2. Lift the baffle and slide it out of the fireplace. You now have access to the chimney.
