Side Wall Protection

BFC36 Balance Flue Heat-Circulating Fireplace

Hearth Installation

Adjacent combustible side walls that are within mini- mum dimensions shown in Figure 24 of the fireplace opening must be protected with CFM Corporation Wall Shield Model SP40 or a specifically built wall shield described in Figure 18.

The special wall shield design described in Figure 18 is an alternate method of adding protection to side walls and can be used in place of the SP40 with the same wall clearances specified for the SP40. Rt must =1.85 minimum.

Examples of wall shield insulation:

1.Manville - CERAFORM 126, K=.27, 1/2 inches thick

2.EH2416, K = .458,

1 inch thick required.

A hearth extension is required to protect a combustible floor in front of the fireplace. Refer to Figure 21 for mini- mum dimensions and mounting detail.

Note: Hearth Extension must not cover the air inlet opening of a fireplace.

The hearth extension described in Figure 21 must be a durable non-combustible material with a minimum (total) Rt value of 1.09; refer to Figure 22 for examples. The overall height (above a combustible floor), depth and width must be as indicated, with the extension cen- tered to the fireplace opening.

The top of insulation must be covered with a non-com- bustible decorative covering or a piece of .018” mini- mum sheet metal, to protect hearth extension material.

(Fig. 21)

Secure the hearth extension to the floor to prevent shifting, using trim molding or other similar means at three (3) outer edges. Seal crack between the fireplace hearth and hearth extension with a non-combustible

material. (Figs. 21 and 23)
