venting question

[joedunlevy]

"I am think about replacing my wood stove with pellet stove. My question is can I vent the pellet stove into an existing 7" superchimney 2100. The chimney is inside the house and is 15' long from ceiling to cap. Or do I have to run a seperate pellet pipe up the center of the superchimney. Thank You.

You can run your pellet vent a foot or so into the Class A & seal
the area between the ID of the Class A & the OD of the pellet vent,
but the fly ash that comes out of the PV will build up inside the Class A.
In order to clean it, you'll probably have to take stuff apart & the mess
will be hard to contain...
Your best bet is to run the 3" PV into the Class A, increase to 4" & run a
Stainless Steel liner all the way to the cap.

Hello

I did something very similar.

I replaced my Vermont Castings Wood/Coal stove connected to my house's original center 8" square tiled lined chimney that is approx 25 foot high.
I purchased a larger pellet stove that used 4" pellet pipe and ran it into the 8" chimney hole used by the old wood stove using a 8" to 4" metal reducer. Because the chimney is less that 30 feet high and an OAK (Outside Air Kit) is used on the pellet stove, it works great!! The chimney has a cleanout so I can vac up the pellet ash with no issues.

Hope this helps.

I replaced a woodstove with a pellet stove in summer '08. I kept the top 15' of the 8" Metalbestos pipe, and used an adaptor to connect to the 4" pellet pipe. been running this for 2 winters now....no issues, and good draft.

Thats exactly the way mine is done. My 7" is 2100 super chimney is even longer , about 22 ' , well insulated , and it draws exceptionally good. I think it would be redundant and a waste of money to line it and make it smaller.

Thanks for the help guys. I'm thinking about getting a Harman P4300 and it would be very convenient to go into the 7" pipe. I could put a cleanout at the bottom of the superchimney to clean any ash that builds up.

Adapted my Jamestown J1000 to a 7" stove pipe just as you are hoping. Here are some click-able thumbs:

To go from 7" to 3" you will need a 7 to 6 reducer and then a standard 6 to 3 adapter.

+1
many makers will require conversion to 4" for that much vertical.
easier to clean with full reline
