The special wall shield design described in Figure 20 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. CFM Corporation - 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 23 for minimum dimensions and mounting detail. NOTE: Hearth Extension must not cover the air inlet opening of a fireplace. The hearth extension described in Figure 23 must be a durable noncombustible material with a minimum (total) Rt value of 1.09; see Figure 24 for examples. The overall height (above a combustible floor), depth and width must be as indicated, with the extension centered to the fireplace opening. The top of insulation must be covered with a noncombustible decorative covering or a piece of .018” minimum sheet metal, to protect hearth extension material. (Fig. 23) 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 noncombustible material.
