3" or 4" for 28 foot chimney liner for 3" wood stove?

[begreen]

I think I'm going to return this stove if I still can and rethink the project.

When I posted above about putting a 28 foot 4 inch chimney liner for a 3 inch small stove, it was based on what someone told me on the phone who sells chimney liners. This person thought I was putting the 28 foot liner up a chimney from an enclosed, insulated space.

Was he right about that, if it were for an enclosed, insulated space?

Thank you.

That sounds like a good plan. How was the stove going to be used, like an outdoor patio fireplace? There may be some better options including a used stove.

A stainless liner is used to line a chimney pipe.
