I have a basement thimble being un used goes to a 7x11 terra cotta chimney in great shape. Any pellet stoves out there than can be vented this way? Figured running the pipe through the clay thimble with a reducer block plate and then dirext the 4" 90 degrees up toward the chimney
Nope i have a 2 flue chimney main floor has the nc30 seperate basement is unused and feel it needs to be
best if you run a pipe all the way up at 4" exit top through a cap off of the terracotta. the size of the block flue and loss of heat will cause creosote problems.
damm thought pellet wouldnt make much of a build up. The idea of controlled heat down there sounds nice. A stove would heat you out of there. The idea of set a temp and it kicks on and off automatically sounds really appealing for that area
Looking at the Harman diagram, it appears that you can with theirs. Also the local dealer said they do quite a few like that. I did. Will follow up if I have any issues..
as long as the clay liner and bond joints ARE INTACT, and the manual specifically allows NOT running a stainless steel liner, you can do it. As for creosote, don't forget, a properly maintained pellet stove runs more efficiently than most wood stoves, minimizing creosote production....note, the OP doesn't mention if the chimney is in the center of the house or the outside...which are two completely different animals. Central chimneys run warmer, while chimneys with the weather on 3 sides run cooler. Also, running liner can be somewhat pricey. If your tiles are compromised (cracked) by, say, an old chimney fire, you'd need to run liner.
I also have a double flue chimney. Another concern could be the clean out doors at the base. I don't think they seal tight enough to prevent leakage in a pressurized environment.
well, hopefully your chimney itself isn't pressurized positively, but rather negatively, with the warm air draft rising.......so, the pellet pipe is positive pressure, generally going to negative pressure in the flue
Build up of creosote or ash isn't an issue. But the stove you install will determine whether you can or can't. Some local laws and stove manufacturers require a liner. Some local laws and manufacturers don't. What stoves are you looking at?
As stated, some local laws require a full liner. In RI it isn't required; that being said this past winter we only ran a 4 ft pipe up. This summer we did install a full liner on our 52i insert for peace of mind as well as making it much easier to clean the chimney. I have only run the stove on two occasions thus far this season but it seems to burn better. Could be the pellets (LaCrete) or the liner... maybe both?
