Majestic Fireplaces® SR/SC Series
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 chim- ney pipe for ceiling thickness up to eight (8) inches. When combined thickness of ceiling material, ceiling joists and flooring material exceeds eight (8) inches, adjustments must be made in framing to assure that minimum air spaces to chimney are maintained.
