PelletVent is a complete venting system from DuraVent for stoves and inserts that use oil fuel or multi-fuels (including wood pellets, corn, cherry pits, switch grass, coffee husks, walnut shells, soybeans, wheat, sunflower hulls, rapeseed and sugar beets). The Flexible Chimney Stove Pipe is designed for use in a masonry chimney and features twist-lock connections to easily connect with rigid PelletVent piping. For added durability, PelletVent seams are factory-sealed on all elbows, tees and fittings.
