Stove has been running great all winter. Easy to tell something was not right this evening. Loaded about 5 medium splits. Had lots of secondaries at only 300 degrees or so, not much flame from splits though. Cracked the door, smoke came pouring out, this never happens. Stove got up to 600 or so, secondaries roaring, just didn't seem quite right though. Decided to crack the door again, smoke pours out again. Air is about 3/4 closed, secondaries will stop for a few seconds, then come back with authority and push some smoke out into the house. I shine a light in the slot where air comes out, sure enough I see some tape coming down from pipe connection (sorry for my non technical terms). Took off surround and it looks like the tape has come loose. Now I do have to say that this connection was quite a bear because there is only about an inch clearance at the top of the stove. I believe the liner never did quite make a sealed, flush connection to the stove. I guess the tape had sealed it, until now. Suggestion???? I guess I will call installer tomorrow, same place I purchased from. Should I suggest they use a 15 degree connector from stove to liner? It is definitely not a straight drop from chimney to stove. I know I saw a thread recently that someone used that successfully. Anyone remember who it was? Not sure I even want the installer back, can't say I was that happy with them to begin with, now this! Anyone have a quality installer on Long Island they think could help? Thanks for any suggestions.
