PelletVent Pro® Simpson Dura-Vent Engineered Excellence Applications PelletVent Pro is a venting system designed for stoves and inserts that use wood pellets and oil fuel. It is also built to vent biofuel products such as corn, switch grass, cherry pits, soybeans, coffee husks, sunflower hulls, walnut shells and wheat, to name a few. (Rated for continuous use flue temperatures up to 570° F.
Engineered Excellence® from good science. PelletVent Pro For Biofuels: The Only Choice. 304 316 430 Corn and other biofuels have higher water content than wood pellets. When water combines in the flue with elements in corn, such as sulfur, nitrogen, and phosphorus, the condensation is highly acidic. These acids cause common pellet chimney vent liners made of 430, 304 and 316 stainless steels, to corrode.
PelletVent Pro® Simpson Dura-Vent Engineered Excellence PelletVent Pro for biofuels (patent pending) features a metal-to-metal seal as the primary protection against leakage. A high temperature silicone o-ring, completely encapsulated between the inner and outer wall, provides a secondary seal. Primary metal-tometal connection seals the joint Encapsulated o-ring provides a secondary seal Silicone seals fail at temperatures exceeding 600°F.
