• Examine the gasket that seals the glass to the door frame.
If necessary, replace this with gasket obtained 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.
How to Replace Gaskets
Your Montpelier Medium Insert uses rope-type fiberglass
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 ...................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.
