BR/BC Series Woodburning Fireplaces 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.
BR/BC Series Woodburning Fireplaces Chimney Supports The chimney system is supported by the fireplace for vertical chimney heights less than 30' (9 m) above the hearth. Chimney supports are required if the vertical height exceeds 30' (9 m) with SK8 chimneys or 20' (6 m) with 3-wall chimneys. Locate chimney supports at ceiling holes or other structural framing at 30' (9 m) (SK8) or 20' (6 m) (3-wall) heights. Spacing between chimney supports must not exceed 30' (9 m) (SK8) or 20' (6 m) (3-wall).
BR/BC Series Woodburning Fireplaces Framing 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: When using 2 x 6 framing construction, the allowable air space between the front of the SK8 outer pipe and 2 x 6 framing is reduced to 1" (25mm) as tested and approved by U.
BR/BC Series Woodburning Fireplaces Straight-Up Chimney Installation To mark the centerline of the flue, put the fireplace in final position and measure out from the wall: 8¹⁄₄" (210 mm) 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.

BR/BC Series Woodburning Fireplaces Installing the Chimney System Pipe Section Start by attaching the first chimney section to the collar on top of the fireplace. Pipe Rim UP Install the pipe as pictured in Figure 16. 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.
BR/BC Series Woodburning Fireplaces 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. Canadian Requirements for Insulation Shield 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.
BR/BC Series Woodburning Fireplaces 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. Air Space Clearances Combustible framing material MUST NOT penetrate AIR SPACE (shaded areas). Check the chimney top installation instructions for details on how high above the roof top the chimney sections (all pipes) should extend.

BR/BC Series Woodburning Fireplaces Side Wall Protection Hearth Installation Adjacent combustible side walls that are within minimum dimensions shown in Figure 23 of the fireplace opening must be protected with a specifically built wall shield as described in Figure 20. A hearth extension is required to protect a combustible floor in front of the fireplace. Refer to Figure 23 for minimum dimensions and mounting detail.
BR/BC Series Woodburning Fireplaces WARNING: HEARTH EXTENSION MUST BE INSTALLED IN ACCORDANCE WITH FIGURE 23 AND MUST NOT COVER THE BOTTOM FRONT OPENING OF THE CIRCULATING MODEL. Example of Determining Hearth Extension Equivalents Alternate noncombustible materials may be used providing the (total) thermal resistance (Rt value) of the alternate material employed is greater than or equal to R = 1.09 Thermal resistance (R) or thermal conductivity (K), may be obtained from manufacturer of the material.
