3. Apply a 1/8-inch (3mm) bead of gasket adhesive
to the channels. Fold the provided gasket rope
in half to find its center point. Start at the top or
bottom center of the door and push the new
gasket into place uniformly without stretching or
compressing the gasket material. Pinch the
gasket into place as necessary. Use masking
tape to hold the rope in the channel along the
top and bottom of the door.
4.
Once the gasket is installed, tighten the door’s
sidepieces to clamp the gasket in place. The
sidepieces form one side of the gasket’s
channel, and hold the gasket rope along the
sides in place.
5. Re-install and close the door immediately to fully
seat the gasket in the channel and ensure
complete adhesion. Check the gasket seal using
a dollar bill or aim a flashlight into the space
around the door from the outside (then look in
through the glass at the gasket
– if you see light,
the seal will leak). The leak will most likely be
where the gasket was not fully inserted into the
channel, or where stretched (thinner), or
adjacent to an area where the gasket was
compressed (thicker).
6. First, adjust the gasket as necessary by
reseating it uniformly. If that does not work,
adjust the latch mechanism (see below and Fig.
14 and 15) so it applies more pressure when the
door is closed. Keep the door closed and do not
burn the stove for 24 hours while the adhesive
cures.
7. Remove the tape before burning the stove.

:
1. Test gasket seal quality with small latch
adjustments first. The curved door geometry
means a little movement goes a long way. Too
much pressure makes the door difficult to open
and close and prematurely wears the roller and
the gasket.
2. Loosen bolts, adjust jackscrews, or use a
combination of both to shift the latch assembly
to apply more, or less closing pressure to the
gasket (See Fig. 14).
3. If necessary, loosen the five bolts securing the
door side plate containing the handle (mounting
holes are slotted). Make additional adjustments
by sliding the side plate in towards the stove
(less pressure), or out away from the stove
(more pressure) (See Fig. 15).
