When installing a pellet stove insert, what type of flue liner is required? Is it necessary to run the flue liner all the way the the top of the chimney and cap it? Or can you run the flue liner to just below the chimney cap?
Both wood burning and pellet inserts are very much the same in the fact that they should use a 304 or 316 stainless steel liner system, flexible or rigid, that is sized to the opening of the flue collar on the appliance. The liner can indeed be supported and terminated just below the existing chimney cap. It is not necessary to use a factory top plate and cap, if the existing cap is in good condition. Metal strapping or fabricated brackets can be used to support the liner.
