Currently have a quadrafire woodstove which goes to a brick chimney in the center of my home. Upon closer inspection it looks like the woodstove pipe actually runs the entire length of the chimney. What do I need to do in order to convert to a pellet stove? I am planning on buying a Harman P61a. I am pretty handy and feel like I can probably do the job myself. Thanks for any and all advice!

I used an adapter to transmission from 6in.
insulated stove pipe to the double walled pipe
used on the pellet stove , My installation was
done in 2002 and have never had a problem .

I have had it done two ways. First was an adapter to a fireplace chimney and the existing chimney was used. The second, done by the same guy was to run a 4" all the way from the stove to the cap through an existing wood stove pipe. These installs were done about 10 years apart and he explained that they had learned from experience. Never had any problems with either one although moved from where the chimney adapter install was done 18 years ago so don't know how it held up.
any thoughts on cost for the second option? I know it will depend on area but im just looking for a ballpark. thanks!
Suggest calculating the EVL (Equivalent Vent Length) needed, based on the # of T's, Elbows, and pipe up to the adapter -> the length of flex liner required in the chimney..
Only say this because if you have a stainless flex liner already installed, and in good condition, depending on calculated EVL, you may just want to keep using it vs. investing in 4" stainless flex pellet liner, which can run $350 - $500+ for just the basic liner kit, not including any additional adapters or pipe needed for stove hookup. ( For a complete install around here, I would expect to be paying $750 - $1000. )

I have a 8" 20' chimney and I installed a rigid 4" stainless steel insert from top to bottom with a clean out tee at the bottom. Works good and is to code. The guy who installed it modified the original 8" cap to fit the 4".
So even though the pellet exhaust is pressurized and wood pipe is under a vacuum, you can just hook right up? I would have expected pellet smoke to blow out of the gaps.
Can the adapter be placed near the old woodstove and screwed right into the single wall interior stove pipe. In other words, more 6" stove pipe and minimal 4" pellet vent?
People have run up inside 6" with pellet vent all the way out or tied into different chimneys and such here before with proper fittings etc;. Whatever they do needs to be safe and work right. I didn't specify 6" black single wall. That's why the OP needs to research for options. IMO direct vent is the way to go on pellet stoves but some don't have that option.
The OP has a brick chimney so I'd say going from the pellet stove to that would be an acceptable scenario. Out of the pellet stove up and into the brick chimney. Some still run 4" all the way up and out even if they have an existing masonry chimney.
