Adjusting The Damper; Adjusting The Front Doors - Vermont Castings Defiant 1945 Service Manual

ADJUSTING THE DAMPER

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 in the centre of the damper (Fig. 3).
2. Use the Allen wrench supplied with your stove; turn the pressure screw about one-half
turn clockwise to increase the tension or counter-clockwise to lessen the tension.
3. Test the damper's closing action. Do not over-tighten the screw, as this can cause
binding when the parts expand under heat.
4. When the damper closes smoothly and snugly, tighten the lock nut and replace the
griddle. (Fig. 3)

ADJUSTING THE FRONT DOORS

The doors are factory-set to ensure a good seal between them and the stove front. If
necessary you can adjust their position slightly by loosening the bolts that hold them to the
hinge strips on their edges.
Defiant doors are held on by two hinge pins which are secured to the inside of the door with
a hinge strip held on by two 7/16" hex head bolts. To adjust the door properly you must first
determine which door or doors are out of alignment. To do this, close the doors slowly and
observe how they line up. Do not remove the doors from the unit. Based on what you see,
slightly back off the bolts in the hinge strip holding the misaligned door so that the door may
move relative to the hinge strip and pins. Close the doors again and adjust the loosened door
so that it fits properly with the other door. Carefully open the door again and re-tighten the
hinge strip bolts. Reclose and check to ensure a good fit. Repeat until a desirable fit is
achieved. Be patient. It may require several attempts.
