During the summer we had several bats (15 in all) take up residents in our Vermont Casting Resolute Stove. I was forced to completely dismantle the stove. It has run for about 20 yrs with no real problems. After removing all the baffles and dampers, completing a through cleaning I put everything back together. There seems to be no sealant or mastic on any of the parts, just metal to metal. I checked things twice to make sure everything was installed correctly. We are now experiencing draft problems. My question is; Has anyone taken this type stove apart before. What my I have done wrong or is it possible that the stove is now acting like new and needs to be broken in again. Any help would be greatly appreciated.
