Direct-Temp / Pellet is a revolutionary, high performance venting system. This one-of-a-kind concentric system is two vents in one. The single pipe design integrates both fresh air intake and flue gas exhaust for Pellet applications. Direct-Temp / Pellet is ideal for both sidewall and through-the-roof venting solutions. DT/Pellet components are used in conjunction with DT/Gas pipe lengths and all Selkirk Pellet systems. Selkirk’s proprietary siliconized fiberglass seal adds an extra layer of protection to prevent joint leakage of any fly ash and combustion products.
