Double Wall Chimney Pipe Installation

Double wall chimney pipe installation.

If double wall black pipe sections dwb are to be used the double wall black adapter dwba is required to be attached at the stove collar. A cold exterior chimney will produce less draft and will generate more creosote. As you assemble each pipe section secure the outer wall using three 10 3 4 self tapping stainless steel sheet metal screws. To make the transition from insulated chimney pipe to single wall stove pipe a universal pipe adapter will be needed.

Locate the end of the pipe that has the insulation recessed down. Continue assembly maintaining the clearances to combustibles. It may be necessary to attach the adjustable length dwb18a section to the chimney ceiling support prior to installing the sections. The screws should be equidistant around the pipe perimeter.

Secure the dwb18a to the ceiling support with sheet metal screws. We recommend bracing vertical venting every 5 to 6 feet. Now it s time to start putting our insulated double wall class a chimney pipe together.
