Majestic Fireplaces® BR/BC Series

Installing Outside Air Kit

An outside air kit is installed in all BR/BC Series Fire- places. If desired, or if local codes mandate the use of an air kit, then an AK-MST is required to complete the installation (from air kit to the outdoors). If the outside air kit is to be used, the AK-MST MUST be installed BE- FORE the fireplace is enclosed. Refer to the AK-MST instructions for field installation.

The inside dimension of the frame must be the same as the hole size selected from Figure 13 in order to provide the required 1¹⁄" (38 mm) of air space between the outside diameter of the chimney and the edges of the framed ceiling hole.

lap strips at least 1/2" (13 mm) to provide a positive joint. (Flat safety strips are packed with fireplace.) (Fig. 14)

Safety strips are used to ensure that any combustible materials in front of the fireplace are protected even though a noncombustible hearth extension is required.

If fireplace is to be elevated above the floor, a “Z” shaped metal safety strip must be fabricated and used to protect combustible surfaces in front of the fireplace. This “Z” shaped safety strip is not provided but must be fabricated of metal with each horizontal leg at least 1¹⁄" (38mm) wide and equal in length to the metals strips provided with the fireplace.

Note: Safety strips are not required over noncombusti- ble floors where all supports at the base of the fireplace are noncombustible.

Four (4) nailing flanges are supplied with the fireplace (found on the fireplace hearth). To level the box and secure it firmly in place, remove the nailing flanges from the hearth and install at the sides of the fireplace as

shown in Figure 15.
