Defiant Woodburning Stove
30001693
Check the Operation of the
Primary Air Shutter
The primary air shutter is at the back of the ash drop
and is visible from the back of the stove. (Fig. 39) The
shutter must open and close freely when you move the
thermostat lever. If it doesn’t, remove any obstruction. If
you need assistance, consult your local Vermont Cast-
ings Authorized Dealer.
Do not change the adjustment of the cable in an at-
tempt to gain increased firing. The air shutter controls
how much air can enter the stove, but chimney draft
is the force that pulls air into the stove. If changing the
thermostat handle position does not lead to changes in
the fire’s intensity within four or five minutes, it’s prob-
ably due to weak chimney draft (in the case of a weak
fire you can’t increase) or an air leak in the stove (in the
case of a fire you can’t decrease).
Adjust the Damper as Needed
The tension on the Defiant’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 cen
-
ter of the damper. (Fig. 40)
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.
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.
How to Adjust the Door Latches
The Defiant’s doors should close securely to prevent
accidental opening and to keep air from leaking into
the stove. On adequately adjusted doors, the handles
should resist slightly as they are turned to the closed
position and the doors themselves should be drawn
slightly toward the stove.
Over time, the gasket around the doors will compress
and the latches may need adjustment.
To adjust the latches, loosen the small lock nut, rotate
the striker screw a half-turn, and re-tighten the small
lock nut. (Fig. 41) Your stove kit includes an Allen
wrench for latch adjustments. Hold the striker screw to
keep it from turning as you tighten the lock nut. Make
repeated small adjustments until the setting is right.
