When you get a good lock, you will hear the pipe clearly snap together. Once sections are snap-locked in place, it is extremely difficult to get them apart. Make sure the pipe is firmly snapped and locked together as each pipe section is mounted. When installing elbows, only outer pipe will snap- lock. Middle pipes simply slide into position. Be sure to always attach straps on upper elbow to a structural framing member. (Fig. 17) 7412948 11 SR/SC Series "A" Woodburning Fireplace Continue installing the pipe as required until pipe is installed up through the ceiling. At this point, you must install a firestop spacer. Installing the Firestop Spacer in the Ceiling Hole A firestop spacer is used to keep pipe spaced properly and required for safety. Nail the firestop spacer (at each corner) to the framing members of the ceiling hole. NOTE: A firestop spacer is not required at the roof. Hole sizes listed in Figure 13 for angled firestop spacers provide minimum required air space to chimney pipe for ceiling thickness up to 8" (203mm). When combined thickness of ceiling material, ceiling joists and flooring material exceeds 8" (203mm), adjustments must be made in framing to assure that minimum air spaces to chimney are maintained. UP FP558 Fig. 16 Install pipe, listening for the snap-lock to fasten. Pipe Section Pipe Rim Hem Pipe Rim Lance Proper Firestop Spacer Installation Figure 18 shows different installation procedures for both an area that isan attic and an area that is notan attic. If the area above the ceiling is not an attic, position the firestop spacer with the flange on the ceiling side and the angled portion extending up into the hole. If the area above the ceiling is an attic, position the firestop spacer with the flange on the top of the framed hole and the angled portion extending down into the hole. Firestop spacers are not available for nor are they required on vertical walls. DO NOT put any sealant around the area where the outer pipe slides through the firestop spacer. If you seal this area, it may cause a fire hazard. Elbow Strap Angled Strap Fig. 17 Attach straps to a structural framing member. FP270/271 Support Structure Elbow Strap (must be tight) Ceiling Hole Framing Angle Firestop Chimney Support Strap (must be tight) Canadian Requirements for Insulation Shield In Canada, an attic insulation shield is required to prevent attic insulation from contacting the chimney section. Framing dimensions for the chimney hole should measure 14..." x 14..." (368 x 368mm). An attic shield MUST be installed on top of attic joists (above the floor level).

Nail each corner of attic insulation shield to the framing members of the ceiling hole using 8d nails. Attic shields are not required at the roof. Continue Installing Pipe to Complete Run Continue attaching pipe sections to complete system to next level always being careful that the pipe is firmly snapped 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 on, Page 8, Fig. 9. Bend straps as necessary and make sure they are secure so they will support the weight of the chimney. A chimney support is 2..." (64mm) 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 on Page 12, Figure 18. Penetrating the Roof Run pipe to roofline. Since the 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 centerpoint of the flue system. Drive a nail up through roof at the center point. This will determine center point on outside of the roof. 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 of roof hole. There must be a 1... (38mm) 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 struc tures.)
