NOTE:
Combustible wall fi nish materials and/or surround materials must not be allowed to encroach the area defi ned
by the fi replace front face (black sheet metal).
Never allow combustible materials to be positioned in front of or
overlapping the fi replace face
(
Figure 41, Page 43
)
.
Non-combustible materials, such as surrounds and other fi replace trim, may be installed on the fi replace face, but they
must not cover any portion of the removable glass panel or control compartment.
Vertical installation clearances to combustible mantels vary according to the depth of the mantel
(
Figure 6
)
. Mantels
constructed of non-combustible materials may be installed at any height above the fi replace opening. However, do
not allow anything to hang below the fi replace hood.
Minimum clearance requirements include any projections such as shelves, window sills, mantels, etc. above the
fi replace.
NOTE:
To avoid heat-related fi nish damage, we recommend the use of high temperature paint (rated 175° F or higher) on
the underside of the mantel.
INSTALLATION PREPARATION
The fi replace is shipped with all gas controls and components installed and pre-wired. Before installing the fi replace,
follow these steps:
1.
Remove the shipping carton, and retain the front of the carton (used to protect the fi replace during construction).
2.
Remove the shipping pad, exposing the barrier and front glass door.
3.
Remove the barrier and glass door
(

.
NOTE:
Place the barrier and glass door on the shipping carton to protect its surface.
