Help with stove pipe options for my setup thanks

[cjweaver13]

So we moved here about 1.5 years ago and when we arrive the previous owners installed a 40K btu propane stove. Prior to that it's my understanding they had a traditional wood stove, but they were older so switched before selling the house. Last year after running on propane, I decided this year we'd switch to pellet stove for 1/3 the operating cost if my figures are close. I went with a used Harman Accentra free standing stove which will arrive Thursday.

The current pipe is a vertical mounted class A chimney with 6" stove pipe coming down from the ceiling. The Harman uses a regular pellet stove 3" flue, and also is just a bit too deep without coming off the hearth stone at 90°, so my options are to get creative and put a couple small bends to come up, or lay a row of brick in front of the existing stone so the stove can be pulled up a bit more per se. Wondering between these 2 what makes more sense? People I talk to say venting won't be a problem either way since I'm already running 6" pipe and have plenty of height above the roof line.

Secondly, is it better to just go from 3">6" with an adapter, or is it better to do 2 steps and go 3>4 then 4>6 to meet the existing pipe?

Hard to see the depth in the photo, but maybe you can get a rough sense what I mean. If it were to be mounted perfectly vertical with a tee or 90° elbow, the stove will sit about 4" off the front of the stone. And no, I can't pull it forward or buy a bigger pad so trying to work between the 2 above parameters this year (excuse the dust)

This is how I installed my P61A with existing 6” stove pipe. Been 8 years like this.

I used3 inch and connected into the 6 in class A chimney
with a 2 to 6 connecter and have never had a problem.
Just remember the gas stove pipe is not rated for a pellet stove
Don't forget to plug the stove into a surge protector!

For Cory S, how often do you have to clean the ash out as I see no clean out T?

I do it every 2nd season. Honestly, I could get away with every 3rd season. There’s maybe 1/4-1/2” dusting in there at most.

No kidding, you must do the leaf blower trick regularly then? My P61 is about 1/2” a month in the T

WOW….. That’s a LOT….. No tricks here. My ash bucket catches around 99% of ash and flying embers. I also adjusted my exhaust vacuum for max efficiency, so it wasn’t pulling excessive draft/heat up the flue.
