Q. on installing woodstove in existing fireplace

[gspro]

One of the other posts said this:

"As per your pic, fireplace looks mostly interior. If up to code, that means it does not even need lined! Obviously a liner is best, especially since it will save you have to reparge your smoke chamber to spec, etc..... "

My chimney is interior, what does 'reparge your smoke chamber to spec' mean? If I don't need to use a liner, would I just run stove pipe up into the clay flue? What do I gain by using a liner in an interior chimney?

For either case, if I have to use a ss liner or not, can I use some type of insulation instead of creating a steel base plate?

Thanks.

There are two different ways to install inserts, a direct connect is a pipe going up to the first flue tile with a block off plate at the damper. This will work if your chimney is the same inside diameter of the stoves flue collar exhaust, but is a pita to clean since you have to pull out the whole insert and pipe. The best way is to install a full liner, better draft and cleaning is much easier, no moving the insert. Some smoke chambers where the fireplace damper is located need to be modified or cut to allow a liner to fit through. your stove manual should explain both methods.
