PelletVent 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 DuraVent's 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. PelletVent is UL listed for 3 in. 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.
