Option 1: Both “Front” sides are open top configuration.
Option 2: One “Front” side is open top configuration.
For See-Through models, sides are not required to be
open, but at least one front side of the chase MUST be
open and unobstructed.

charge configurations as specified. Reduced discharge
area will interfere with proper operation of the heat man-
agement system. Overheating of appliance and combus-
tible materials will occur.

2. If Dimension E in Figure 4.2 is greater than two
inches, a piece of mesh screen with 1/2 inch x 1/2
inch opening
MUST
be installed on the top of the
framing above the appliance.
The screen will prevent objects from falling through
the opening and onto the top of the appliance,
causing a fire. The mesh screen may be available at
a hardware or home improvement retailer.
For a
Single-Sided
appliance, the front and both sides
of the chase MUST be open and unobstructed. A rear
support stud may be installed along the back wall to ensure
secure mounting of the discharge assembly.
WARNING! Risk of Fire!
Minimum dimension of opening
MUST
be 2 inches! Appliance and combustible materials
will overheat.
WARNING! Risk of Fire! DO NOT
block discharge opening!
DO NOT
install finishing material on top plate framing!
