IMPORTANT
The facade must be removable
once installed. The facade is
designed to overlap any facing
material installed on the front of
the fireplace. If thicker material
is installed, use the facade as a
template and make sure it can be
easily removed for servicing.
1. Combustible material must be
installed flush with the fireplace. It
may not project in front of and on
the fireplace (i.e. the steel facade of
the fireplace) (Figure 12).
2. Non-combustible materials such as
brick, stone or ceramic tile may proj-
ect in front of and onto the fireplace
facing (Figure 13).
