Diagram for 7'' DuraTech Ceiling Support Kit

7" DuraTech Chimney Cap is required where the chimney pipe terminates above the roof line. This Chimney Cap has removable screws to allow for easier cleaning of the chimney and spark arrestor screen. Includes spark arrestor screen.

6" DuraTech Storm Collar this aluminum storm collar is required for use on any through-the-roof installations using a roof flashing.

7" DuraTech Roof Flashing provides leak proof roof penetration. The purpose of the roof flashing is to weatherproof the roof where the chimney penetrates the roof. The flashing gets tucked under the shingles and the shingles are cut around the flashing if needed. The flashing is sealed to the roof with silicone to provide that needed seal to prevent water from getting under the flashing and getting into the attic or house, then a storm collar is placed over the flashing and sealed to the chimney pipe with a high temp silicone to prevent water from running down the chimney.

7" DuraTech Attic Insulation Shield is required for installations that pass through an attic to prevent insulation and debris from accumulating near the chimney. The Attic Insulation Shield fits over the Firestop Radiation Shield or Support box and consists of two-parts - a collar and a base.

7" DuraTech Round Ceiling Support is used when passing through a flat ceiling. It includes a built-in, twist-lock starter section for DuraTech Chimney. Use a Snap-Lock Adaptor, or a DuraBlack Slip Connector to transition to single-wall stovepipe, or use a close clearance adaptor to transition to DVL Double-Wall Stovepipe. The Round Ceiling Support requires a 14 1/2" x 14 1/2" framed opening. Included is a 1 1/2" wide trim collar. This round ceiling support will support up to 60' of DuraTech Chimney.

  • DuraBlack Chimney Adapter - 8778 DuraBlack Chimney Adapter - 8778 - This adapter is recommended to connect DuraBlack single-wall stove pipe to DuraPlus or DuraTech chimney pipe if you do not require adjustability in your stove pipe height.

It keeps the outer wall cool while ensuring high flue gas temperatures for optimum draft performance. The inner wall is 25% thicker than competitive chimneys, for an extra margin of safety. Designed for normal, continuous operation at 1000 Degree F flue gas temperatures, DuraTech is subjected to rigorous and stringent HT requirements of the UL standard, including one hour at 1400 Degree F, plus three ten minute chimney fire tests at 2100 Degree F.
