This past Nov. I decided to replace my Vermont Castings Encore stove, which I purchased new three years ago, and have not been happy with. I decided to replace the VC with a new Blaze King. There was a Blaze King here when we purchased our place 20 years ago. It was old and I wanted to upgrade and get a more efficient stove. Anyway, in Nov. I downloaded the manual for the Blaze King from their website and studied it front to back. On Dec. 20, I ordered the stove and this past Friday, I drove over 200 miles to pick it up from the nearest dealer. I got it in the house today and put it in place. Low and behold, there is a newly revised manual (printed Jan. 18, 2006. There is something new added to the new manual! The following statements were not in the 2005 manual: "Due to high efficiencies of these units, Blaze King recommends the use of double wall stove pipe from the stove top to either wall or roof exit" (2005 manual says 22/24 guage single wall is acceptable); and "A minimum of 36" vertical rise is recommended prior to using any elbows" (this was not stated in the 2005 manual). These statements are recommendations. I have a wall exit which is only 24 inches above the stove top. The chimney is brick with a stainless steel liner in it. Last week I had the liner insulated. I have never had any draft problems. The stove sits on brick and has brick behind it and on both sides (good clearance all around). So, what can I expect with only a 24" vertical rise and then a 90 degreed elbow rather than the recommended 36" vertical rise. Is there any reason I can't use the single wall connector pipe? I have e-mailed the factory to get their response, but thought I would see what you all had to say.
