New to this website. Looking for help on Vermont Castings "Defient Encore" model bought in 1997. Used the stove for 6 years and took it with me when I moved to another home. Stove has sat unused in shop and now wish to install again. As I look it over before installing, I notice that when I move the damper control on lower right side of unit, the damper "door" does not move. I can reach into the top loading door and move the damper door by hand tho. Do you suppose the stove has to be hot before the damper control moves the damper door?
