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 4 in. Wall Strap Support Bracket accommodates both indoor and outdoor installations, crafted to support the vent mounted at the tee or on a section of straight piping. For added durability, PelletVent seams are factory-sealed on all elbows, tees and fittings.
