Hello everyone, first post here though I have done alot of reading. I picked up a new Hotblast 1551E wood furnace from tractor supply on sale with plans to have it heating by next season as my main/only in use heat source. I know im already on borrowed time for getting wood in but I have at least 8 dried cord and will work on that issue. I could write a book on what I have going on but ill try to keep it short and on topic. At first I thought everything was already decided for the chimney before I picked the furnace. I had an old boarded up basement window hole center of a gable end of the house and said perfect through that and up through the center of the roof peak as it has a big overhang. (Probably 35’ total height from ground for a close estimate total chimney height) Now I realize I dont have enough hole between the 8-10” square sill beam and stone foundation for an out of the box type of through the wall thimble. Even if I did, the bottom of the sill beam is so low to the ground the cleanout portion of the tee would definitely be in the ground. Then I thought maybe put in a well but dont want it to cause water problems down the road. Also I want to add a wrap around porch over this side of the house later on and that would probably make getting to the cleanout even more fun. All this without mentioning I would have two 90’s in the basement plus the 90 of the cleanout tee and probably need 5 foot of pipe (if not 6) layed horizontal from last indoor 90 through wall to outside type HT tee. I dont know how far a horizontal run you can have like this before you see problems and don’t want to have to clean it out more regularly if I dont have to. Enough reading on here and talking to people got me thinking of doing the work required to chase it through the house. I like the idea of reclaiming some of that otherwise lost chimney heat and the good draft and hopefully less routine cleanouts. I would be penetrating 3 floor/ceilings and 2 roofs as it has a roof built at more of a pitch over the original roof. The house is in the middle of renovations everywhere so opening ceilings and walls is no big deal now, some just happen to be open already, haha. Now between first floor and second floor I already have a problem. The floor joists on the first floor dont line up with the second floor and it looks like I would require two 30 degree type HT connections with 5.5-6 ft of pipe between to get my offset around 36” to go through second floor where I want. Just to be clear this is between the first floor floor and ceiling (bottom of second floor) that this offset is needed. If possible safely/legally I can see just building a rather wide chase around the HT chimney pipe and offsets to be aesthetically pleasing, possibly making some way to access if need be. But is this ok for draft and from a safety standpoint? Will a chimney sweep be able to go down say 20 feet from peak and hit these 30 degree offsets and go through them? Excuse my lack of knowledge on the cleaning end of this ordeal but I am assuming they have flexible bruhes and could work from top and bottom of the chimney with the first 30 degree offset being about 4-5 feet from the wood furnaces 6” flue outlet on the back. I just hope to heck that if thats fine I dont run into this issue again between 2nd floor floor and ceiling and probably more likely at the roof beams/rafters but I feel I'm being a bit optimistic... How many offsets can you run in an indoor, approximately center of house chased chimney? I’m sure I’m missing some info but dont want to put anyone to sleep thats still reading this so I will end here. I am open to and appreciate any suggestions from the professionals on here and nothing is set in stone at this point on a through the wall or roof installation. Thanks in advance for any help and I look forward to continue learing!
