Damper Adjustment; Door Latch Adjustment; Gasket Replacement - Vermont Castings Dauntless FlexBurn Catalytic Owner's Manual

B. Damper Adjustment
The tension on the Dauntless FlexBurn's damper is adjustable
to compensate for compression of the gasket that seals the
damper to the upper fireback. To adjust the damper:
1. Remove the griddle. Loosen the lock nut at the center of
the damper, Figure 3.3.
2. Turn the pressure screw approximately one half turn
clockwise with an Allen wrench provided with your stove.
3. Tighten the lock nut. Prevent the pressure screw from
turning as you tighten the nut. Re-test the damper.

Figure 3.3 - Adjust the damper with the Allen wrench.
Tighten the Damper Handle as Needed
A handle on the left side of the stove controls the damper.
The handle attaches to the damper rod with a set screw.
Periodically check the set screw and tighten as necessary.
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. The door handle will be
positioned vertically when the door is closed.
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. Remove and retain the lock nut with a 9/16" wrench, Figure
3.4.
2. Loosen the set screw with a 1/8" Allen wrench.
3. Rotate the pawl 180°. Replace the lock nut. Tighten the
set screw, Figure 3.4.
4. Additional adjustment can be made by removing the flat
washer. Or any combination of washer removal and/or
pawl rotation.
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 additional adjusting of the latch does not enable the door
to seal sufficiently in one area, try adjusting the gasket in that
area. Pack more cement or a smaller diameter gasket into the
channel beneath the gasket so the main gasket is raised and
makes contact with the door frame. If this procedure doesn't
solve the problem, replace the gasket. Instructions for gasket
replacement are given later in this section.

Your Dauntless FlexBurn

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)
3/8" The damper to the damper frame
5/16" 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
3/16" The outer glass panes to the door
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 3.5.
