- Lay a bead of gasket silicone or cement then press
gasket in place.
6. Starting at one end, press the gasket into the channel,
Figure 6.5. Ensure a good joint where the gasket meets
before trimming any excess. Do not overlap the gasket
ends or leave ends with ragged edges.
7. Press the gasketed part firmly against its normal mating
surface to seat the gasket evenly in its channel. Close
and latch the door to do this, or tap other parts with the
rubber mallet (or hammer/block of wood).
8. Clean any excess cement from around the channel, then
let the cement that holds the new gasket dry thoroughly.
9. The stove’s doors may need adjustment after you have
regasketed them. Initially, it may require loosening the
latch to accommodate the new gasket; after a few weeks,
it may need tightening to compensate for compression of
the new gasket. See Figure 6.3 for directions on adjusting
the latches.
3. Determine the correct length of the appropriate-sized
gasket by laying it out in the channel. Allow an extra 1-2"
(25-50 mm), and mark the spot to be cut.
4. Remove the gasket from the channel, place it on a wood
cutting surface, and cut it at the marked spot with a utility
knife.
Twist the ends slightly to keep the gasket from unraveling.
5. Lay an unbroken 1/8" (3 mm) bead of silicone or cement
in the newly-cleaned channel, Figure 6.5.
All Gasketed Construction Gaskets
Other gaskets form seals between all other non-moving parts,
but these are not subject to the same wear and deterioration
as gaskets on moving parts. It is unlikely that you will ever
need to replace these gaskets unless the involved parts are
disassembled and then put back together. If this is the case,
the job should be done only by a qualified service technician.
5/16" diameter gasket seals the following parts:
• The lower fireback to the back panel
• The left and right air plates (inner sides)
• All connections between the stove plates.
D. The Chimney System
Creosote
Your appliance is designed to reduce creosote build-up
significantly. However, regular chimney inspection and
maintenance must still be performed. For safety, good stove
performance, and to protect your chimney and chimney
connector, inspect your chimney and chimney connector on
a regular schedule. Clean the system if necessary. Failure
to keep the chimney and connector system clean can result
in a serious chimney fire.
When wood is burned slowly, it produces tar, organic vapors
and moisture that combine to form creosote. The creosote
vapors condense in the relatively cool 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 within the flue system that can damage the chimney
and overheat adjacent combustible material. If a significant
layer of creosote has accumulated —1/8" (3 mm) or more
— it should be removed to reduce the risk of a chimney fire.
You can never be too safe. Contact your local fire authority
for information on what to do in the event of a chimney fire,
and have a clearly understood plan on how to handle one.
If you do experience a chimney fire, act promptly to:
• Close the damper and air control lever.
• Get everyone out of the house.
• Call the Fire Department.
Inspect the system every two weeks during the heating
season as part of a regular maintenance schedule. To inspect
the chimney, let the stove cool completely. Then, using a
mirror and a strong light, sight up through the flue collar into
the chimney flue. If you cannot inspect the flue system in this
fashion, the stove must be disconnected to provide better
viewing access.
