Using existing chimney for wood stove.

[Dmitry]

Hi ,just talked to my buddy and said he can't use existing chimney that he uses for oil furnace for wood stove as well. He got 2 openings in his chimney. Both appliances is in a basement. Last year he used it with some kind of small stove but got rid of that. it was connected same way as oil furnace but in separate openings. He asked why he can't use it and I just said because folks on HEARTH.COM said so. .
Can you shed the light on it?

I believe that is building code, only 1 fuel fired unit per chimney.

 

[Dmitry]

Yeah , but what the reason ?

You have to distinguish between chimney and flue. It is one appliance per flue. If a chimney has two flues you can connect two units to it; each on its own flue. Your buddy was ok and could put another stove on that flue.

Ok , its the same shaft that goes from basement to outside, so I guess it's one flue technically speaking

One would think like fire, gas explosion, CO issue, non coverage of insurance claim from loss. It is against NFPA and RBC.

Yes per chimney flue.
