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 Ceiling Support Fire Stop features sturdy steel construction and helps protect upper floors from fires. Required for running a PelletVent system between floors, its safe design centers the pipe to ensure the necessary 1 in. clearance. For added durability, PelletVent seams are factory-sealed on all elbows, tees and fittings
