Vermont Castings Defiant
6. If the element is in good condition and clean, re-
install it in the stove and replace the refractory
access cover.
7. Replace the fireback, the five bricks and their clip,
the left and right wedges, and the baffle. When you
install the lower fireback, be sure to align the two
slight recesses in its bottom forward edge
behind
the mating tabs on the firebox floor. (Fig. 37) When
you install the wedges, be sure to place their rear
vertical edges against the
outermost
left and right
edges of the lower fireback, to ensure a good seal
between the lower fireback and the stove's outer
back. Tap them downward to seat them snugly, but
do not overly tight.
8. Clean the chimney and chimney connector.
Operate the stove in your usual manner for two
weeks, inspecting the chimney and the chimney
connector frequently during this period.
If creosote does not build up as fast, it is likely that
the performance change was caused by fly ash depos-
its on the catalytic element. However, continue the
inspections of the chimney system for a few weeks to
ensure that proper performance continues.
If you continue to find a significant creosote
buildup or if you continue to see excessive smoke from
the chimney, the catalytic element will need to be
replaced. Contact your nearest Vermont Castings’
Authorized Dealer for information about a replacement
element.
NOTE: Use only the replacement catalyst supplied
by a Vermont Castings Majestic Products Company
dealer.
Replace the Stove Gaskets as Needed
Your Defiant uses fiberglass rope gaskets to make
a tight seal between some parts. With use, particularly
on moving parts, gaskets can become brittle and
compressed and can begin to lose their effectiveness.
These will need periodic replacement.
The sizes of replaceable gasket are listed below,
along with their applications.
Gasket Diameter... ...And the Parts it Seals
5/16" The griddle to the stove top
(wire reinforced gasket)
5/16" The damper to the upper fireback; the
front doors to the stove front; and the
doors to each other.
3/8" The ash door to the front of the bottom
panel
If you need to change a gasket, first obtain an
appropriate replacement from your Vermont Castings
Majestic Products Company Authorized Dealer.
Wait until the fire is out and the stove has cooled.
Be sure to follow the standard safety procedure for
working with dusty materials: wear safety goggles and
a dust mask.
The procedure for replacing gaskets is the same,
regardless of the gasket location. Follow these eight
steps:
1. Remove the existing gasket by grasping an end and
pulling firmly. (Fig. 41)
2. Use a wire brush or the tip of a screwdriver to clean
the channel of any remaining cement or bits of gasket.
Remove stubborn deposits of cement with a cold chisel
if necessary. (Fig. 41)

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 unravel-
ing.
5. Lay an unbroken 1/8" (3 mm) bead of gasket cement
in the newly-cleaned channel. (Fig. 42)
6. Starting at one end, press the gasket into the
channel. (Fig. 42) Ensure a good joint where the
gasket meets before trimming any excess. Do not
overlap the gasket ends or leave ends with ragged
edges.
