Smoky Smell with Harman P68
Maybe someone can help me out with this. Last Thursday, I had a Harman P68 pellet stove installed in my below grade basement. They ran the vent up about 6Â, then about 4Â horizontal to the outside. The vent terminates about 16" from the foundation and 12"-16" above the ground.
For the Thursday, Friday, and most of Saturday, there was no smoky smell coming from the basement. I turned the room sensor down to 65 degrees. About 8:00pm Saturday, I noticed a heavy smoke smell coming from the basement. I cranked the stove up, but the smell was still there and extended up to the 2nd floor.
ItÂs now Wednesday and the smoke smell is still evident in the house. I donÂt know if itÂs old or new. I checked the back of the stove near where the vent joins the stove, and noticed that same smoky smell every now and then. I also noticed the smell occasionally along the vent pipe up higher. I checked and the exhaust fan is working, and the smell is not coming from the outside. Several things I noticed;
Saturday afternoon it got damp and overcast with rain for the next 2-3 days. Could it be that the exhaust was flowing back down the pipe?
They used silver tape to cover the joints on the pipe. I donÂt know if they calked underneath that. I used the extra tape they gave me to seal up the joints I thought might be bad. Could it be leaking from the joints?
The smell seems to be worse when the stove meets its temperature and is idling or off.
Anyone with a similar problem or idea? Thanks
