How to Replace Gaskets
Your Montpelier Medium Insert uses rope-type fiber-
glass gaskets to make a tight seal between some parts.
With use, particularly on those parts that move, gaskets
can become brittle and compressed and can begin
to lose their effectiveness. These will need periodic
replacement.
All of the gaskets used are made of fiberglass. The
three sizes of replaceable gasket are listed below, along
with their application.
Replaceable Montpelier Medium Insert
Fiberglass Gaskets
Gasket Size ...................And The Parts It Seals
3/8” (1203564) ...............Door to the front - 5.6’
3/8” (30002422) .............Firebox parts
3/16” (1203556) .............Glass to the door - 5.2’
To change a gasket, wait until the fire is out and
the stove has cooled. Wear protective eyewear
and a dust mask. The procedure is the same for
all gaskets.
1. Remove the existing fiberglass gasket by
grasping an end and pulling firmly.
2. Use a wire brush or the tip of a screwdriver
to clean the channel of any remaining cement,
silicone or bits of gasket.
3. Apply a thin bead of high temperature silicone
to the newly-cleaned groove. A 1/8” - 3/16” bead
is sufficient.
4. Place a new gasket into the groove. Wait until
you have placed all but a couple inches from the
end before you trim the end to an exact fit.
•
Examine the gasket that seals the glass to the door
frame. If necessary, replace this with gasket ob-
tained from your local Vermont Castings’ authorized
dealer. Directions for replacing gaskets are given
below.
•
Check the channel at the bottom of the door frame,
and clear away debris if necessary.
•
Carefully place the new glass in the door frame.
•
Secure the clips, being careful not to over-tighten.
Be sure the glass is firmly seated against the gasket.
Close the door gently to confirm the clips have been
properly positioned. It is possible for the glass to be
damaged if the clips have been installed incorrectly
and the door is closed with force.
