Hi all. This is my second winter using my Quadra fire 7100. I also have a Quadra fire 4300 wood stove. The 7100 does not seem to burn nearly as hot as the woodstove. Even at full burn rate I cannot get the soot to burn off the glass. My woodstove rolls fire and washes the glass even at a 1/4 burn rate. The temperature control does work in the 7100 and it will slow down to a lower burn rate when moved all the way to the left but it just does not seem to roll fire like it does with the wood stove. The BTU spec on the 7100 is mayve 1/3 higher than the 4300 but the stoce puts out wsy more heat. The draft on the 7100 is good and my outside air supply pipe is clear (Burn rate does not seem to change even when I have the outside air supply closed). Is it possible that the mechanism inside is not allowing full air to the wood. Not sure how the air wash is supposed to work. Im burning same wood in both fireplaces. The 7100 slow burn has been there from start. The dealer checked out installation by contractor but went out of business after we purchased fireplace. Any thoughts would be appreciated.
