Hi! Trying to find model-specific troubleshooting info for a stove is not easy, so I'm hoping for some feedback. I have a Vermont Castings Intrepid II (catalytic), about 6 yrs old. Works great, but I am having a damper problem. I can close the damper with no problem, but the "d-plate" that the bar hits against to open and close keeps coming loose, so the bar misses the re-opening piece if I need to add wood. It gets pretty exciting as I open the doors an poke it open with the fireplace-poker so it vents! :bug: Do I need a new damper? New plate? A call to VC? Thanks!
