Making the move from a small woodstove to an Englander. I've been considering moving to a pellet stove for a few years back in 2013 /14 I though that would be my last year with wood and was actually out looking at pellet stoves, nut by the following heating season oil had gone below $2 a gallon so I just used the fire in the basement started by the button on the wall. Well oil is creeping back up some to the point it makes sense to have some supplemental heat. So I've been looking a pellets again and just scored a deal on a 3 season old Englander so I'm now in the install process. I'm putting it on the hearth in place of the wood stove venting out the existing Masonry Chimney. It's nearly in the center of the house so Ill have to run the outside air down through the floor and then to either the front or rear of the house. I'm leaning toward the rear because its a walkout basement and it would essentially be 8' off grade where the front of the house would only be about 1'. It will however result in about an 8-10 foot farther run. So question one is will the length be an issue 18' vs 9' ? Question two is I want the exhaust to run to the chimney opening center on the stove for aesthetic reasons. I have a tee with a clean out for the stove and couple of 45's but it looks like the cleanest way is to align the TEE to and use a 45 to go vertical it puts the pipe just about perfect on the stove, from there its about 2' to an elbow and into the chimney. Will the clean-out TEE be mostly effective at a 45 Deg angle. Last question what methods have people used to get from 3" pellet vent to an 8" masonry chimney opening? I have a 3-6 Duravent to stovepipe adapter and 6-8" Stovepipe adapter left over from the wood stove and will probably use that initially but would like something cleaner so the stove can be closer the the hearth. I have no plans at this pint to line the chimney as it is in good shape I may get there if it doesn't draw right but I'm gonna try it this way first. Thanks in advance for your time and experience.
