vi it is a shame you are having problems with the stove. We all have opinions here but I think the important thing is that the dealer sold you an appliance that will not do what he and the manufacturer sold it to do. Just like if you bought a freezer that wouldn't freeze food. My take is that you don't get in to telling them how to fix it. Tell them to fix it or give you your money back and get it out of there. Just like you would with any other appliance and dealer. If you give them suggestions you just give them things to argue with you about. Showing them the opinions of strangers on the Internet won't bolster the case either. If they make one change that you suggest and it does not fix it, it will make it harder to seek restitution later if it comes to that. The thing they can't argue with you about is that the stove they sold you and the installation they performed will not operate to manufacturer's specifications using the manufacturer's instructions. Instructions that were developed to operate the stove efficiently and safely. Plain and simple. Traumatic as the whole thing is it ain't your job to figure it out or fix it. Believe me, it will cost them a hell of a lot less to fix it than to haul it away and try to sell a used stove. I am not a wood stove installation expert but I made my living for 35 years negotiating.
