206009 Insul Chimney Pipe 9×6 (2 Pack)

Type HT chimney pipe special augured in mineral wool insulation filling the space between stainless steel walls is only 1 inch thick, yet provides 17 times the insulating valve of brick. This optimum density of insulation stops expansion noises and resists and contains surges of heat. This allows the system to be enclosed with only 2 inch clearance to combustibles. The “solid pack” density comprises about 85 percent air. The mixture of extremely fine fibers trap this air in the pores of the insulation and also blocks radiation heat transfer. Tested to 2100 degrees F. UL listed. Stainless steel outer casing and inner liner. Double-wall pipe with solid pack insulation. Tested to withstand 2100 F (degree Fahrenheit). UL (Underwriters’ Laboratories) listed. This test helps to prevent product damage or structural hazard during brief periods of this excessive chimney temperature. Normal temperature is 1000 F. Pipe Data: Minimum clearance to combustibles – 2″. Stainless steel thickness: Inner lining and outer casing – .012″; couplers – .016″. Insulation density – 23 lb/cu ft (pounds per cubic foot). Insulated pipe lengths are furnished with a Locking Band (preassembled with captured nut and screw).
