Vermont Casting Defiant 2190 and the damper won't stay closed, I've checked the gasket around the closure and it looks fine - not pulled out, shredded, etc. I'll close the damper handle and the damper plate will drop back to open pretty much right away. Sometimes it'll teeter there like its finely balance but it doesn't ever seem to sit in position with authority.
I've taken to propping the handle closed with a cut 2x4, but would like it to work right vs having to force things. Have the manual for the non-cat and the cat (this is the cat version), the non cat manual shows an adjustment, the cat version doesn't. other than incorrect/oversized gaskets installed by prev owner I'm wondering what else I might look for in the way of something wrong or something to adjust
photos and/or video available if that'll help
Thanks
