Hi all,
I am looking to install a Ka-6 in my basement and a LL pioneer upstairs. Can the two stoves utilize a single flue and if so, how big should it be? Thanks.

It is my understanding that the Federal government would like you to use a separate flue for each stove. You can have one chimney but must have two flue's.

In a single word, Don't. Most states/citys will have restrictions on two appliances feeding one flue. You will have people tell you that they did it or their buddy did it and or that know somebody that did it and it worked fine but you take a big risk. If you overload the capicity of the single flue you potentially can have gas back up into your house, gas includes carbon monxide a real nasty one.

I'd consider using one flue for a backup oil boiler [part time], and a coal boiler [full time].. but I wouldn't share a single flue with two coal appliances..
