Drectly replace a wood stove with pellet stove - keeping the chimney

[mavmav]

I have a standalone Woodstove and wish to swap it out with Pellet Stove.

The exisiting chimney is a Class A double walled and insulated stainless steel running from the ceiling straight up through the attic.
I'm trying to decide whether to cap it off or continue using it.

Can I use this chimney as is or does it need to be lined or is it a complete no-no?
I’m hoping its a straight forward hookup with just a reducer.

What pipe can I use from the stove to the ceiling?

Any advise would be appreciated.

Thanks

Yes, you can do it. See my post (#7) in your other thread:

Hey MavMav,

I just had a similar job done on my home. My wife and I replaced our wood burning stove with a pellet stove. The pre-existing stainless steel chimney extrudes through the wall and goes about 10 feet past our second storey.

The installers ran a liner inside the chimney and connected it to our new pellet stove.

No problems as of yet!

Where in Ontario are you?

MavMav,

I just removed an old coal stove and replaced it with a pellet stove. Chimney is unlined save for the top several feet. It is a fieldstone fireplace/chimney setup. All I did was buy a chimney liner kit which included 25' of 4" stainless steel flex liner, a cap, cleanout tee, 4" to 3" reducer/adaptor, etc. I installed it myself, a relatively easy job, and it works great.

One word of warning...wear gloves when handling the SS liner...the cut ends are sharp! Don't ask me how I know.

What kind of pellet stove?

You can get addapters to go from 3"to 6" , or 4" to 6" if your chimney is bigger I don't know if you can get a pellet chimney adapter . I just did this and went with a
totally new chimney because I would have had too many elbows . I was also advised that my vent would work better going straight up . plus my insurance Co . was complaining about the age of my chimney 25Yrs old . I am trying to get my insurance rates down so I did everything to code . It cost me an extra $150worth it to me .
You are going to love your new stove ,having the control is awesome .

Yes, they are available (in DuraVent pipe, anyway). I went from 4" to 8" so I could use my woodstove pipe.

When I did my install I bought a 4" - 8" adapter, but couldn't use it, guess they are designed for going into a metalbestos chimney, I was replacing a woodstove into a masonry chimney. Had a local sheet metal shop fab an adapter for me. Still got the Simpson one, anybody wants it, gimme $40 and shipping it's yours. Cost me more than that, just taking up space, PM me if ya want, might take less, oops, prob'ly catch a slap for talkin' about it here, soory, mods, web

......guess they are designed for going into a metalbestos chimney....

Hoss, there are 2 additional adapters I had to get to make it work. Thanks to Eric at kinsman for getting me set-up with these just when i thought the same as you did, that it wouldn't work.

Thanks Eric!!

The one the shop made works great, only charged me $35

Wow! We were told when we hooked up our pellet stove in place of the wood stove that we did not need a pipe going to the roof. We have a double lined chimney with 6 flues. Are we supposed to have this? The stove has been working fine and there are no draft problems.

You only need it in some circumstances ,I needed a roof chimney because I have fence on two sides ,a storage building on one and the driveway on the other .
The vent has to be two feet from a fence or building .I had no where to go but up .
