NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
A hearth extension is not required with this
appliance. If a hearth extension is used, there
are two methods of installation. One, the fin-
ish combustible or non-combustible material
could be ended by butting up against the front
face of the fireplace and the floor panel (refer
to Figure 40).
Two, the finish combustible or non-combustible
material could be ended below the fireplace
(refer to Figure 41). Remove the floor panel
as shown in Figure 40 by removing the screws
on the right side of the panel and sliding the left
side away from the tab. Discard the screws and
floor panel. It is critical that there is at least a
1/8" gap between the bottom of the door track
and the surface of the finish material.
Non-combustible materials, such as surrounds
and other appliance trim, may be installed on the
appliance front face with the exceptions.
Vertical installation clearances to combustible
mantels vary according to the depth of the
mantel. See Figure 42. Mantels constructed
of non-combustible materials may be installed
at any height above the appliance opening.
