Step 1. FRAMING
Frame these appliances as illustrated in
Figures
13 (DRT40ST), 14 (DRT40PF), 15 (DRT40CL)
or 16 (DRT40CR).
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 nailing
flanges - 8 (DRT40ST), 4 (DRT40PF, DRT40CL
and DRT40CR) - as shown in
Figure 12
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 8
for clear-
ances of framing members to cabinet parts in
the nailing flange area. The nailing flange itself
is exempt from these clearances.
