I've been asked to install a pellet stove to replace a wood stove. The existing vent looks like Simpson Duraplus 8" inner and 10" outer. I asked my stove suppliler if they can sell me a transition connector for 3" pellet vent to the 8" Duraplus. He said he could but that his installer recommends sleeving through with all pellet vent but wasn't totally convincing me on why (something about fly ash accumulation). The existing vent is through a chase in the center of the house and runs straight up through two stories to the roof cap. I would think that if the vent is cleaned well it would work to simply connect the pellet stove to it. Anybody know about this or think of a reason not to do it?

I have my insert connected to my old wood burning 6" flex vent (with the DuraVent adaptor) and up the chimney! No issues.

I ran the pellet vent up the full length of my 8". I was told there would be too much draft for the stove, and too much ash accumulation in the vent if I just hooked up at the bottom of the 8", and it would not pass inspection here. Your local code would be different though.

Thanks for the info.

Well there is one benefit to having too much draft, no smoke in the place on a power failure.

Had no idea this could be done, I spent over $600 on a four inch liner and adaptor kit 5 years ago, plus the better part of a Sunday jamming it into my existing Selkirk 6"...

4" all the way to above the roof, with an OAK. I don't have a smoke issue. I've cut power to my stove at various points in the burn cycle and never had any smoke either in the house or coming out the OAK.
I would think a drawback of too much draft would be severely reduced efficiency, but what do I know.
