wood stove burn problem
I have a pretty old VC Resolute that I used to love but it is now causing problems since I started using it 24/7 a couple of years ago. First it started building creosote and after some tiles cracked with a minor chimney fire, I had the flue re-lined, going from 8" square to 6" round. Now I get nowhere near the draft I used to get and now when I close the damper to use the secondary burn, the fire simply dies down and smolders and I am now building an enormous amount of creosote. (If I close down, I need to clean my chimney every week!) I get the stack temp to 400 before I close down, but it doesn't look like I'm getting any secondary burn, just generating a lot of smoke. Now, I don't close the damper, just lower the thermostat really low on the primary air. Cuts down the creosote, but also goes through more wood. Any ideas what the problem might be and what I can do to solve it?
