Step 1. FRAMING
Frame this appliance as illustrated in
Figure 9
.
All framing details must allow for a minimum
clearance to combustible framing members as
shown in
Table 5 on Page 9
. If the appliance is to
be elevated above floor level, a solid continuous
platform must be constructed. Headers may be
in direct contact with the appliance top spacers
but must not be supported by them or notched
to fit around them. All construction above the
appliance must be self supporting,
DO NOT
use
the appliance for structural support.
Side Nailing Flanges
The fireplace should be secured to the framing
at the side(s) and/or rear of the unit using the
factory-provided nailing flanges. Install the 8
nailing flanges as shown in
Figure 8
using the
existing screws.
Position the fireplace within the framing. When
required, the flanges may be bent 90 degrees by
hand or with the assistance of a hammer. Use
wood screws to secure the nailing flanges to
the framing.
See Table 5 on Page 9
for clear-
ances of framing members to cabinet parts in
the nailing flange area. The nailing flange itself
is exempt from these clearances.
Floor Nailing Tabs
Secure the fireplace to the floor as shown in
Figure 8
.
*This dimension can be reduced to 41" (1041 mm). This results in 0" (0mm) clear-
ance between framing and unit framing spacers (The 41-1/2" dimension permits
easier fireplace installation, if unit is installed after framing is erected).
** Based on 5/8” drywall. Use 23" for 1/2" drywall.
