Stove pipe reducer

[mczee]

I moved into a house with existing 6" pipe installed from the ceiling up through the attic and roof. I have a stove that takes 8" pipe. Does it make a difference if the reducer is at the stove side or the ceiling side?

Most stove manuals say don't downsize. It will make a difference in how the stove operates regardless of location, particularly in a milder climate.

What stove is this for and how tall is the chimney pipe?

The stove is brand Centennial Heating Systems Inc, model-step down, serial no- RSD0182. The chimney from stove to ceiling is about 5 feet, not sure what is happening in the attic as there is no access, then 6 1/2 feet from roof to top of pipe.

Sounds like this is an old, legacy model stove. Moving to the Classics forum.
The stove might work on the smaller flue, if not, smoke rollout may be an issue.

Try it close to the stove. Open doors to stove after increasing combustion air/opening any dampers and open the door(s) slowly when about to reload. This might help fight smoke rollout. Some stoves are okay being reduced though poor draw days may not be your friend.
