Framing and Finishing
Hearth
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 height and widths refer to
Figure and the Mantel Chart below.
Noncombustible mantels and legs may be installed at
any height and width around the appliance.
When using paint or lacquer to finish the
mantel, such paint or lacquer must be heat
resistant to prevent discoloration.
