I have a whitfield II insert and it has been great up until last spring. The stove started to put out a strong smoke scent, but of course because it was spring i put it off until the last minute which is now winter. I pulled the stove out and put it in the shop and gave it the most thorough cleaning ever. I replaced the gaskets on the exhaust fan and the damper, which i thought was the culpret because it had a burned out spot in it. After all this I gave it a test run in the shop, and no smoke, but when i put it back inside the house the smokey odor coming from the tubes is even worse. WHAT THE HECK! Oh yeah i also replaced the door gasket and cleaned all the pipes going out the chimney. Please help, its getting colder and my wifes getting madder.
