Pellet Vent 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 3 inch Tee Support Bracket Wall Strap offers sturdy, 24-Gauge construction and helps support the vent mounted at the tee or on a section of straight piping.
