Framing With Platform
Inches (mm)
The platform should extend the full width
and depth of the fireplace base.
Top Vent With Horizontal
Termination In A Corner
(MJ) Need review of updated dimen-
sions in tables below (4-17-08)
* D shown here is not
dimensioned to the vertical
center of the horizontal
framing. This is to allow for
the required 4" clearance
above the vent and the 1"
required clearance below
the vent. This does not
include the suggested 1/4"
rise per foot for horizontal
runs.
** With the facade installed
(required - sold sepa-
rately), the appliance base
will need to be elevated a
minimum of /4" above the
floor to allow for the proper
fit of the facade (i.e. use
/4" board minimum as
platform).
u
When installing in a corner configuration, one of
the rear stand-offs will need to be removed.
Step 1. FRAMING
Frame these appliances as illustrated in Figure
9, unless the appliance is to be installed in a
corner.
See Figure 10 for corner framing installations.
All framing details must allow for a minimum
clearance to combustible framing members as
shown in Table 6 on Page 6.
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.
The fireplace should be secured to the side fram-
ing members using the unit's nailing flanges on
each side of the fireplace front. See Figure 8.
Use 8d nails or their equivalent.
