I just had a Quad 7100 installed, and I notice the manual says the warranty is void if the unit is "over fired." By brother recently discovered the baffle in his Vermont Casting wood stove was deformed, and he was told by the company that they would not cover it because the unit was obviously "over fired." So what exactly does that entail? Should I install a thermometer on my unit and monitor the fire box and/or flue temp? If that's the case, why don't they just integrate a thermometer in the unit? Can I over fire it simply by keeping the damper open too long? I also have a 30 year old Fisher wood stove, and I have noticed the 7100 seems much more sensitive to small movements in the damper. It also seems to burn with much taller, wildly dancing flames. This is really nice to watch, but it makes me nervous. Any insight?
