It's a Keystoker 105. Top vent. It's new this year, but I've had it running for about 3 weeks now. It just started smelling about 2 days ago, and came on gradually. I already ripped my chimney apart, and found no obstructions, and vac'd out everything that I could reach.
I suspect that I have fly ash blocked some port somewhere. I do seem to have decent draft up the stack (match test).
The air intake to the combustion motor is adjsutable, and I did close that (per the manual) to try an reduce the smell. Didn't make any noticeable difference.
Have 2 CO detectors and they're not going off.
The smell is not overpowering, but it is there.
Anybody familiar with this model?
Thanks in advance.....
