Majestic Fireplaces® SR/SC Series

9. Hearth Installation

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 non-combustible 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 non- combustible 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 fire- place hearth and hearth extension with a non-combus- tible material. (Figs. 23 and 25)

WARNING: HEARTH EXTENSION MUST BE INSTALLED IN ACCORDANCE WITH FIGURE 23 AND MUST NOT COVER THE BOTTOM FRONT OPENING OF THE CIRCULATING MODEL.

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. Factors are related by the formula K = 1/R.

T = given thickness

R = thermal resistance for a given thickness (T) K = thermal conductivity

Noncombustible material with a lower R value may be used, provided thickness of material is sufficiently greater to maintain an equivalent (total) thermal resistance (Rt).
