SR/SC Series "A" Woodburning Fireplace Planning Information Preplanning an installation is very important to ensure safety and to save time and money. An installer must predetermine where a fireplace will be set and how the chimney system will be run. Mounting the Fireplace A fireplace may only be mounted on the following surfaces: 1. A flat combustible surface. 2. A raised wooden platform. 3. A concrete block or other solid object placed beneath each of the four (4) corners of the fireplace.
SR/SC Series "A" Woodburning Fireplace Installation Chimney Supports The chimney system is supported by the fireplace for vertical chimney heights less than 30' (9m) above the hearth. Chimney supports are required if the vertical height exceeds 30' (9m) with SK8 chimneys or 20' (6m) with 3-wall chimneys. Locate chimney supports at ceiling holes or other structural framing at 30' (9m) (SK8) or 20' (6m) (3-wall) heights. Spacing between chimney supports must not exceed 30' (9m) (SK8) or 20' (6m) (3-wall).
SR/SC Series "A" Woodburning Fireplace Framing Option For Circulating Models Only — Framing can be constructed before or after the fireplace is set in place, however, most installers build the frame before setting the fireplace. Frame fireplace with 2 x 4 lumber or heavier materials. Refer to framing dimensions in Figures 1, 2, 3 or 4 for basic fireplace specifications. NOTE: Framing should be positioned to accommodate wall covering and fireplace facing material.
SR/SC Series "A" Woodburning Fireplace Straight-Up Chimney Installation To mark the centerline of the flue, put the fireplace in final position and measure out from the wall: 9¹⁄₄" (235mm). Mark a spot on the ceiling directly above the fireplace. Draw a line parallel to the back wall through this mark. (Fig. 11) Using a plumb bob positioned directly over center point of fireplace flue collar, mark the ceiling to establish the chimney center point. (Fig.

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. Pipe Section Installing the Firestop Spacer in the Ceiling Hole Pipe Rim UP Hem Lance Pipe Rim 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.
SR/SC Series "A" Woodburning Fireplace 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.

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. Penetrating the Roof Run pipe to roofline.
