I need some advice on how to vent my U.S. Stove #5510 Pellet stove into my existing fireplace.
Current situation...
I have a clay tile lined chimney with a wood stove insert currently in the fireplace.. no pipes just venting straight up... i know not exactly to code.. but that is the past...
The chimney is on the exterior wall of my house
I am replacing the wood burning insert with this pellet stove, it is not an insert. it will sit on the hearth in front of the opening of the fireplace.
The installation instructions for the stove, clearly state that it is not to be vented directly into a masonry fireplace, my initial thought was well... if it is a lined chimney it should be ok... After reading their FAQ section on the their page.. it really has more to do with the size of the flue and exhaust not being expelled quickly enough due to the increased size of the flue. I guess i understand that.
So i think these are my following choices ..
1. I thought the easiest and least expensive option, would be to cut a rectangular opening through the fireplace to the outside and make a heavy steel (iron) rectangular insert to fit inside and help support the chimney, cover it with a flashing and make a round hole to pass the 3" pellet vent pipe straight through. i could make the rectangle large enough to also pass the optional (according tho them) fresh air intake pipe.
Option 1 has me worried about the structural integrity of my chimney...if i cut the rectangle will it cause damage before i could put in the steel insert .... etc.... kind of scary...
2. Purchase a chimney liner kit that consist of a flex pipe, top cap, collar and appliance adapter.. since this will be over 12' the manual says to increase the diameter of the pipe to 4" .. chimney liner option is around $320... however I am reading that this pipe should also be insulated in wood burning applications, which would add another $225 dollars to my cost. So now I am up to $545
Option 2. Sounds expensive
3. Purchase regular pellet Vent of 4" diameter with a top cap, chimney plate, 12' of straight pipe, tee with clean out, appliance reducer, etc.. This option is around $350.
Option 3. Somewhat expensive but also worried about supporting that length of pipe inside the chimney from just the top?
I would appreciate some advice from the experts that are here...
Thanks
John
