Framing
This appliance is designed to be recessed into combus-
tible framing with non-combustible material pre-installed
on top and side. Drywall or combustible materials (mini-
mum 1/2 inch thick) are designed to contact the non-
combustible material/appliance as called out in Section
10 Finishing.
This appliance has been thoroughly tested to minimize
drywall cracking and/or the protrusion of screws “screw
pops" when framed as shown below.
Framing should be done in a manner similar to framing a
window or door: Double-2x4/2x6 as a header for horizon-
tal strength and utilizing Jack or Trimmer stud fastened to
the King studs for vertical strength.
Note: Refer to Section 10 for important information
related to facing, drywall speci
fi
cations and decorative
barrier front information.
Note:
Header
MUST
be installed on end as shown in the diagram.
If elevating the appliance, the base of the appliance
should also be constructed in a similar manner to prevent
settling.
Refer to Figures 3.7, 3.8 and 3.9 for information regarding
framing when the Passive Heat Kit is installed. Install the
Passive Heat Kit per the instructions provided with the kit.
NOTE:
E & K dimensions will change if Passive Heat option is installed.
Reference the instructions included with the Passive Heat Kit.
