Got a fisher w 8" oulet but a 6" flue

So i got a great deal on a fisher..free. I have a 6" hole in the ceiling though. I have been to two new buildings with brand new stoves w 8" outlets that neck down to 6" is that ok for me to do?

The house originally had a woodburner with a 6" pipe. stove was removed for a gas stove 4" sleave into the 6". Now i want to put a wood burner stove back in. The stove is a two door fisher with an 8" outlet. Learning so much from this site since i found it two days ago. got to get home to inspect it to find out exactly what model it is.

You have a grandma or grandpa bear depending on the size. 6 bricks across the rear make it a grandpa. These stoves are designed to burn with those wide doors open so they all used an 8" flue. The larger stove was a Papa and it uses a 6" flue and a single door. This leads me to believe that so long as you don't burn with doors open, the firebox doesn't need an 8" flue but anytime you open both of those doors wide to add fuel you risk smoke spillage.

A really nice and long 6" flue will outdraft a crappy 8" flue.

Welcome to the forums. You can neck it down (I'd do it right at the stove), but like others said you have to be careful not to run it wide open, you'd probably have some smoke spillage.

perfect that is what i wanted to hear. i had read that the taller the pipe the better. It will be approx 22' to the top with the vaulted ceilings. Thanks so much.

How bout the best vendor for 6" single wall for the main span from the stove to just before the ceiling?

Nothin off the top of my head, but go with either a heavy wall pipe or stainless single or double wall pipe. Look on the internet, if for nothing else just to get an idea of exactly what you want. Google it.

I agree BG. It would pay to go with a black double wall pipe for sure.
