Newbie to the Pellet world : trying to fight the high cost of propane heating. Have been doing lots of reading, this forum is a great source of info : Special thanks to smwilliamson. Expect stove delivery, this week, of an Ecoteck Elena 48K BTU 85% pellet stove. I had been pondering an Ecoteck or a Quad Edge-60 for more than a year, and recently some really good Ecoteck clearance prices (plus free shipping and no sales tax) pushed me off the fence. I would have preferred the Edge-60, but the price is about $2000 too high. I also liked the Enviro line of stoves, but my wife wouldn't go for the look of the Omega/Maxx. I will self-install, with proper permits and inspections (of course), but would like some feedback/comments on my flue design. The stove will be in the corner of a one-story sun-room, out the back and then up, with the vent-cap about 3 feet above the edge (gutter) of the "A" frame roof. The 3 inch stove exhaust goes to a 3" to 4" adapter, then 45 elbow, then 90 elbow, 2 ft horizontal thru-the-wall, then T, to an 11 foot vertical rise. (This is all 4" Duravent Pellet Pro). I will install an OAK too. I appreciate any comments or advice. Thanks.
