Pellet Vent is a patent-pending venting system for stoves and inserts that use multi-fuels, including wood pellets, corn, cherry pits, switch grass, coffee husks, walnut shells, soybeans, wheat, sunflower hulls, rapeseed and sugar beets or oil fuel. As a result of DuraVents cutting-edge manufacturing process and commitment to innovation, PelletVent is uncompromised in attention to detail and performance. Select components are available in black to enhance interior aesthetics. Pellet Vent is UL listed for 3 inch clearance to combustibles in the USA and in Canada. Its double-wall, air-insulated design offers superior performance. PelletVent seams are factory-sealed on all elbows, tees and fittings. Since the introduction of pellet stoves in the 1980s, DuraVent has been recognized as the industry leader in venting systems for pellet stoves. Today, approximately 3 of every 4 pellet stoves in the US and Canada are vented with a DuraVent pellet system.
