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).

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.

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.
