(Fig. 17) Continue installing the pipe as required until pipe is installed up through the ceiling. At this point, you must install a firestop spacer. Refer to Figure 18 for appropriate spacer orientation. 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 12 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. Proper Firestop Spacer Installation Figure 18 shows different installation procedures for both an area that is an attic and an area that is not an 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.

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. 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)(SK8). (An attic shield MUST be installed on top of attic joists (above the floor level). (Fig. 19) NOTE: In the U.S., it is a good idea, although not always required, to install an attic insulation shield where blown-in insulation is planned to be used in the attic. Install the attic insulation shield with the flanges on its base extending down into the framing hole. 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 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..." (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. A chimney support cannot be mounted directly to the fireplace. 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 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 centerpoint. 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. NOTE: The air space dimensions in this manual that pertain to model 11CF chimney pipe have been changed from 2" to 1" (51 - 25mm) clearance for first joist space only. This change only applies to Majestic Fireplaces models STR42 and CVR42 fireplaces. Because of framing concerns these models, and only these models, have been tested and approved at the reduced clearance. In all other cases the minimum air space referred to on the UL label on...
