NOTE:
Combustible wall finish materials and/or surround materials must not be allowed to encroach the area defined
by the fireplace front face (black sheet metal).
Never allow combustible materials to be positioned in front of or
overlapping the fireplace face (
Figure 41
).
Non-combustible materials, such as surrounds and other fireplace trim, may be installed on the fireplace 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 7
). Mantels
constructed of non-combustible materials may be installed at any height above the fireplace opening. However, do
not allow anything to hang below the fireplace hood.
Minimum clearance requirements include any projections such as shelves, window sills, mantels, etc. above
the fireplace.
NOTE:
To avoid heat-related finish damage, use finish materials rated 175 °F, or higher, on the underside of the mantel.
INSTALLATION PREPARATION
The fireplace is shipped with all gas controls and components installed and pre-wired. Before installing the fireplace,
follow these steps:
1.
Remove the shipping carton, and retain the front of the carton (used to protect the fireplace during construction).
2.
Remove the shipping pad, exposing the front glass door.
3.
Remove the glass door (
Page 58
).
NOTE:
Place the glass door on the shipping carton to protect its surface.
