Continue Installing Pipe to Complete Run Continue attaching pipe sections to complete system to next level always being careful that the pipe is firmly snap locked in place before proceeding to next pipe section. Chimney Supports If chimney supports are required, they are installed the same as elbows. Nail chimney support straps to adjacent structural framing, as shown in Figure 8, Page 8. Bend straps as necessary and make sure they are secure so they will support the weight of the chimney. A chimney support is 2..." long when installed. Consider this dimension when determining how many straight chimney sections are needed. NOTE: Chimney supports are generally used in long runs in a chase installation. Additional Ceilings If you encounter additional ceilings, repeat same steps required for first ceiling installation. Refer to firestop illustration in Figure 21. Penetrating the Roof Run pipe to roofline. Since chimney system must be vented to the out-of-doors, you must use an approved termination. If a chase is used, refer to the installation manual provided with the termination cap. Locate Chimney Centerpoint on Roof Use same procedure detailed in locating center point of the flue system. Drive a nail up through roof at the center point. This will determine center point on outside of the roof. 20001384 13 SHR Series Woodburning Fireplace Cut and Frame Roof Hole Size of roof hole varies with the type of chimney termination installed. Refer to installation instructions provided with the chimney termination to find correct size roof hole. There must be a 2" (51 mm) air space between outermost portion of chimney sections and any adjacent combustible surfaces. (Combustible surfaces include burnable materials such as: ceiling members, joists, flooring, combustible insulation and roof structures.) WARNING: DO NOT PACK REQUIRED AIR SPACES WITH INSULATION OR OTHER MATERIALS. Mark an outline of the roof hole around the centerpoint of the 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. 23) The SHR52 has a framing shield between the front standoffs that may be used to attach finish material. (Fig. 25) Finish Wall Finish the wall with material of your choice. Do not install a combustible mantel shelf less than 12" (305 mm) from the top of the fireplace opening. Do not install a mantel face plate less than 6" (159 mm) from top of fireplace opening. (Fig. 29) If a combustible material is used below a flat mantel shelf, consult your local building codes for minimum clearance from top of fireplace opening to bottom of mantel shelf. All joints (top, bottom and sides) where wall or decorative facing material meets fireplace surround must be completely sealed with a noncombustible material. (Figs. 24-29) NOTE: No side wall protection is required for fireplaces installed at 45° to two (2) side walls (corner installation). FP559SHR Fig. 23 Minimum clearances to combustibles.
