Clearance to Combustibles
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
Figs. 4a and 4b, and the following Mantel Charts.
The fitting of a bay window trim kit does not effect
the distances and reference points referred to in the
diagram and chart.
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.
