As the title indicates, I'm fed up with the high, unpredictable oil prices and I'm about to starting heating our 1100sq/ft ranch style home from the basement using a Shanendoah R-77 built in the early 1980s. I've already replaced two of the firebricks that had crumbled into pieces during the move and run a couple of loads through the stove and am quite happy with it so far. I only had junk wood on hand so didn't get a ton of heat out of it, but enough to know the stove is still in good working order. I have a question I'd like to pose as a newbie wood burner. This stove has a thermostatic damper in the door. How can I be sure this is working properly. I've read that this is a week point on the stove. When I turn the knob on the front I can see the flap opening and closing, although it does not close all the way. What should I be looking for here? Thanks for any advice!
