Hi everyone. I was corresponding with you guys last month about my older model Lopi Yankee and how it was burning. It has been much better but my newest problem was that yesterday the whole house filled up with smoke. The smoke was barreling out of the blower area. We cleaned out the vent piping outside thinking it was clogged and the stove ran great the rest of the night. Well, this morning, the same thing happened. I called the guy I bought it from and he said that there was probably a break in the seal and to recaulk. We will be doing that. Apparantly if there is a leak in the piping caulk, the fan sucks the smoke back into the stove and shoots it out into the house instead of outside. My question is, why did the stove run fine after we cleaned out the piping, wouldn't it have smoked us out all night if there was a leak or could it be an intermittent thing?
