B. Gasket Replacement
(as Needed)
Your Aspen C3 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
3/8” Round
Door Gasket (40” Needed)
3/16” Round w/PSA
Gasket for glass (36” Needed)
If you need to change a gasket, first obtain an appropriate
replacement from your Vermont Castings’ 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 steps:
1. Remove the existing gasket by grasping an end and pulling
firmly. (Figure 3.4)
2. Remove old cement using a wire brush.
3. Apply fresh furnace cement to the gasket channel. A 1/4”
wide bead is sufficient.
4. Install new gasket being careful not to stretch.

C. Door Latch Adjustment
The front door of the stove should close securely to prevent
accidental opening and should close tightly to prevent air
from leaking into the fire chamber.
Over a period of time, the gasket around the door will
compress and the latch may need adjustment. To adjust the
handle, follow this procedure:
1. Slightly loosen the 1/4-20 hex head bolt located at the
rear of the latch assembly inside the firebox, Figure 3.2.
2. Tighten the top 1/4-20 phillips-head screw, Figure 3.3.
Adjust as needed until a snug fit is achieved.
Test the door seal. Close the door on a dollar bill and attempt
to pull it free. If the bill is freed with little resistance, the
gasket isn’t snug enough at that spot. Continue to make
small adjustments until the setting is right.
If proper resistance can’t be achieved the gasket need to
be replaced.
