I have noticed a slight smoke smell around the front top area of my Fireview since it was new ,,, when burning in the low (.5 -.75) draft opening and cat burning.... Gaskets are all good... Well I called Mike at Woodstock and was amazed when he told me what it was according to my chimney set up... I helped a local chimney guy install my insulated liner down my 22 foot masonry chimney... We then cut open the block about a foot below the tee and installed a clean out door..We also made a shelf right inside the clean out door so all the ash stayed right there... Well, my chimney guy said he leaves the cap off the bottom of the tee so as to allow ash to drop down to the clean out door... big mistake! Even though I had the clean out door closed Woodstock told me that numerous people have done the same thing,, causing cold air to be reversed into the stove on a low setting with the tee uncapped... Well I got the tee closed up on the bottom and what a difference! No more smoke smell and I even get the occasional wispy flames on a .5 draft setting.. Stove now burns 100% better at a very low setting apparently drafting properly... Thanks to Mike a Woodstock for the remedy!
