Selkirk L.L.C. has announced its new direct vent system for pellet appliances. The Direct-Temp® direct vent system for gas appliances is now also UL listed for pellet burning appliances. Two new innovative components will allow the conversion of any pellet appliance into a simpler, cleaner and more efficient direct vent system. Direct-Temp's single-pipe design integrates both a fresh air intake and a flue gas exhaust. The outer vent, supplying fresh outside air, is preheated for high-efficiency combustion. The inner pipe is made of 304 stainless steel, which provides exceptional corrosion protection for wood pellets and corn, and allows the exhaust gases to vent. The 304 stainless steel material of the inner pipe permits precision manufacturing tolerances, which ensures tight seals and added structural integrity of the system. The liner has a continuously welded seam, which is superior to lock seam designs that may leak. Direct-Temp is ideal for both sidewall and through-the-roof venting solutions, and has been engineered for optimum appliance performance.Selkirk L.L.C.
