Mantels
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting heights and widths, refer to
Figures 21 and 22. When using paint or lacquer to
finish the mantel, such paint or lacquer must be heat
resistant to prevent discoloration.
Side Wall Protection
Adjacent combustible side walls that are within mini-
mum dimensions shown in Figure 24 of the fireplace
opening must be protected with Majestic Wall Shield
Model SP40 or a specifically built wall shield described
in Figure 19.
The special wall shield design described in Figure 19 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.
Hearth Installation
A hearth extension is required to protect a combustible
floor in front of the fireplace. Refer to Figure 25 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 25 must be a
durable noncombustible material with a minimum (total)
Rt value of 1.09; see Figure 23 for examples. The
overall height (above a combustible floor), depth and
width must be as indicated, with the extension centered
to the fireplace opening.
