I have just had a Quadra-Fire Yosemite wood stove installed. After the first fire the glass turned black. After the second fire, the glass fell out of the door. I re-attached it with some difficulty (the screws did not appear to be properly threaded) and by the fourth fire the glass fell out again and an odd liquid began leaking from the side door. I believe the liquid is black but the stove is black so it is difficult to gauge. Lastly, on the few occasions I was able to get a good burn going it really did not produce a great deal of heat. This has led me to wonder about a few things. 1. I find very little information online regarding consumer experiences with this model. Does anyone have good or bad experience? 2.) The dealer has been fantastic and quickly replaced the front door and glass. However, I am wondering about my 30-day return policy at this point. Does expecting a model that does not have the glass falling out seem unreasonable? 3.) What exactly could this black liquid be? I can't imagine it is creosite (the wood is aged about 8 to 12 months). I spoke to the people at Quadra-Fire and they had never heard of the glass falling out or a black liquid leaking from the side door. 4.) I bought a stovetop thermometer. Does anyone have a sense of how hot I should expect it to burn (or the range of temperatures). Sorry for going on so long. I am a bit new at this and falling somewhat more deeply into debt. Thanks.
