Can this venting be used with a pellet stove insert?

Answer:Yes, and that is actually the most common application for which this DuraFlex liner is used.

I bought a wood burning insert that has a 6 inch flue but my fireplace only has a 4 inch flue. Is there an adapter that can be purchased?
By Collin C. - NFI Master Hearth Professional on February 4, 2013
Answer:Unfortunately, there is not a way to adapt the 6 inch flue collar of the insert to the existing 4 inch flue. Is the existing 4 inch flue masonry or metal piping? If it is masonry, it is possible that any existing flue tiles can be broken up and removed, allowing more space for a larger liner. Under-sizing the insert flue by more than one inch will cause problems with over firing and poor fuel efficiency.
