This is a picture of my 5 year old Napoleon zero clearance. Yesterday it was down to 8 degrees here in the morning and I can heat my 3000s/f house with it. Initailly I had problems with the glass and airwash system but I've developed some techniques to minimize the dirty glass. First is using 2 year old wood. Secondly is loading north/south. For some reason this works best in my firebox. Because of where fresh air enters the firebox it circulates better around the wood when it is N/S. Using this loading technique i can go 2 or three days between cleaning and the cleaning is now easy with just some wet newspaper and ash instead of the constant scrubbing required before.
Now only complaint I have is the sagging doors. If you can see the pic, the doors are very big and heavy. The hinges are blocks that were cast from hollow metal forms instead of being bored from solid steel blocks. Over the course of a season the doors bend the hinges and they touch each other. Luckily the hinges are easily swapped out but its a pain calling the factory each year for a new set. I've helped things by filling the voids inside the hinge blocks with jb-weld. This has strengthed the hinges and slowed the sagging but not completely stopped it. Even with this problem I would recommend the NZ-6000 for people who are interested in the look and extreme heat from a large stove. It really kicks out heat from an utra quiet fan located in the basement. I only hear a "whoosh" of air when it is on. THanks-Joe
