Double Wall B. StovePipe (interior), 6" Adjustable (3-9") (Secur.)
With the Secure Black Double Wall (DL) pipe, Security Chimneys has designed a product that has been successfully tested to 2100 F at 6-inch clearance from combustible materials. This level of safety delivers the peace of mind. Temperature rating of 1000 F Max continuous; 1400 F brief forced fired; and 2100 F 30 minutes tested.
The inner liner is made of corrosion-resistant stainless steel, helping to deliver better protection of the exterior finish. The outer wall features a series of openings that allow for maximum recovery of heat from the flue gases. In fact, it is almost as efficient as a single wall black pipe.
