Tightening The Primary Air Handle - Vermont Castings Defiant 1945 Service Manual

TIGHTENING THE PRIMARY AIR HANDLE

The primary air handle may fall down to the half open position and feel loose. There is a
friction spring on the inside of the stove that must be under tension to work. The actual air
damper handle is the mechanism that holds the spring tight.
1. Using the Allen key supplied with your stove, remove the primary air handle. You
will see the "D" shaft of the primary air thermostat assembly protruding.
2. Using a socket set with a 7/16" socket, remove the two bolts holding the gasketed
right air plate on the inside of the right side and slide the plate out of the stove.
3. Ensure the spring and washer are in place on the primary air thermostat assembly.
The washer goes on the inside of the spring.
4. While pushing in on the assembly to compress the friction spring, slide the handle
back onto the shaft lining up the flat part of the shaft with the Allen key location on
the handle. Push the handle tight against the tight side. Tighten the Allen key to hold
the handle in place and the friction spring engaged. The final step is easier done with
two sets of hands.
