Hey everyone, new here, new to burning. I’ll try to give as much info as I can for my setup at my first home (2500 sq ft) i just moved into. I have an Englander 28-3500 tied into my ductwork. I have a 6 inch flue tied into an 8x13 masonry. I am burning a mix of seasoned wood the previous owners left all sub 20% moisture. Having trouble getting long burn times. Not getting a ton of heat into the ducts but enough to heat the house up about a degree every hour or 2. Ok onto my main problem I have a lot of liquid creosote dripping from the thimble and I’m not sure why. It was already stained from the previous owners and there was no chimney cap. The masonry chimney actually extends another 2 feet below where the thimble goes in. I found this out when sweeping the chimney the whole lower 2 feet was completely filled with creosote all the way to the thimble A lot of water slurry as well because on no chimney cap. Well I cleaned a that crap out and put a cap on and I’m still having stuff dripping Any advice I’d really appreciate it. Maybe run a chimney liner?
