Thank you everyone for your replies.
It is not any news that I have had my reservations regarding chimney dampers. I had thought they were for drafty old stoves not for modern ones but enough people have suggested them for my situation so...I think Kobeman suggested a manometer. Again, where is my dealer.
Matt, The place that sold me the stove did send a service person out once and they replaced the ash pan door gasket. (This was a different person than the installers) I showed him how the clips that hold the glass in place were loose and would even fall out of place if you were to squeeze the glass. He told me he doesn't touch those because he's afraid of breaking the glass. This is unacceptable but I can't make a horse drink water either. I also told him that if I put a dollar bill behind the doors it will pull out against the manuals acceptable tolerances. To which he something like, I'm not stupid, I'm not going to believe everything that the manual says.
I think Quadrafire has a very poor "test" to approve a business to install their product. Or, this dealer totally disregards all that is suppose to be adhered to.
Quad ignores my emails or tells me to contact the dealer and the dealer, in my opinion, shouldn't have a license. But if they sell enough Quadrafires then I guess Quad looks the other way.
Like Northwinds and you and probably others have said, I paid good money for this stove and installation and deserve better but neither outfit has stepped up to the plate.
Matt, as far as what else is wrong besides leaky doors and a stove that overfired and according to page 21 of my manual, by definition, I don't have a warranty because of it. Also it was the installers that told me to leave the door open and avoid the rear vent. But, in their defense, when I do this I still get overfires it doesn't seem to matter. My supporting T Bracket is above the T. not under it. Another thing that I don't think anyone picked up on is the distance away from the house that this pipe is. They used a two foot pipe to go through the wall. It probably should have been 18". On the inside it goes to the elbow so it is maxed out there too. Perhaps the bright side here is if it is further away from the house the house is safer. I don't know.
This is a very questionable dealer and I think Quadrafire should get involved to help save the day but I am not holding my breath.
All I wanted was to enjoy a stove! I never thought any of this was possible. It's a wood stove in the 21st century right?
