6.4.2 Gasket
It is important to replace the gasket with another having the
same diameter and density to maintain a good seal.
1. Remove the door and place it face-down on something soft
like a cushion of rags or a piece of carpet.
2. Remove the old gasket from the door. Use a screwdriver to
scrape the old gasket adhesive from the door gasket groove.
3. Apply a bead of approximately 3/16" (5 mm) of high
temperature silicone in the door gasket groove. Starting from
the middle, hinges side, press the gasket into the groove.
The gasket must not be stretched during installation.
4. Leave about ½" (13 mm) long of the gasket when cutting and
press the end into the groove. Tuck any loose fibers under
the gasket and into the silicone.
5. Close the door. Do not use the stove for 24 hours.
6.5 Exhaust System
Wood smoke can condense inside the chimney, forming a inflammable deposit called creosote.
If creosote builds up in the system, it can ignite when a hot fire is burned in the stove. A very
hot fire can progress to the top of the chimney. Severe chimney fires can damage even the best
chimney. Smouldering, smoky fires can quickly cause a thick layer of creosote to form. When
the stove is operated properly, the exhaust from the chimney is mostly clear and creosote builds
up more slowly.
«Creosote - Formation and Need to Removal
When 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 cooler
chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue
lining. When ignited, this creosote makes an extremely hot fire.
The chimney connector and chimney should be inspected at least once every two months
during the heating season to determine if a creosote buildup has occurred.
If a significant layer of creosote has accumulated (
⅛
" [3 mm] or more) it should be removed
to reduce the risk of a chimney fire.»
6.5.1 Cleaning Frequency
It is not possible to predict how much or how quickly creosote will form in the chimney. It is
important, therefore, to check the build-up in the chimney monthly until the rate of creosote
formation is determined. Even if creosote forms slowly in the system, the chimney should be
cleaned and inspected at least once each year.
Establish a routine for the fuel, wood burner and firing technique. Check daily for creosote
build-up until experience shows how often you need to clean to be safe.
