Mark an outline of the roof hole around the center of the point nail. NOTE: Hole dimensions given in the chimney top installation instructions are horizontal dimensions; therefore, the hole size must be marked on the roof accordingly. Cover the opening of the installed chimney so debris cannot get into the system. Cut and frame the hole. It is good practice to use framing lumber that is the same size as the rafters. Install the frame securely because the chimney top and flashing anchored to the frame must be able to withstand heavy winds. Install Remainder of Chimney Sections Since you have already preplanned the height of your termination according to the Ten Foot Rule, continue to install pipe to the predetermined height. Check the chimney top installation instructions for details on how high above the roof top the chimney sections (all pipes) should extend. Installing Top Housing or Termination Follow the installation instructions provided with the chimney termination you have selected. Installing Chimney In a Chase Refer to Page 5, Figure 4 for an illustration of a typical chase installation. CAUTION: Treatment of firestop spacers and construction of chase may vary with type of building. These instructions are not a substitute for local building codes. You must check your local building codes to determine specific requirements for your city or state. NOTE: Other building materials may be required in addition to Firestop Spacers. Finishing CAUTION: All joints between the finished wall and the fireplace surround (top/sides) must be sealed with noncombustible material to prevent cold air leakage into the room. Only noncombustible material may be applied to the facing of the fireplace surround. (Black painted area) (Fig. 20) Finish Wall Finish the wall with material of your choice. Do not install a combustible mantel shelf less than 12" (305mm) above the front opening. Do not install a mantel face plate less than 6" (159mm) from top of fireplace opening.
