Ensure that the wood base that the appliance will sit on is strong enough to support the full weight of this appliance.
Note: A combined minimum
of 288 square inches of
open area is required for the
convection air outlet to cool the
enclosure. Ensure clearances
for Convection Air Outlets
are met.
See clearances CB72EPV
in this manual as there are
dierent methods as to how
this can be achieved.
Description CB72EPV
Note: This appliance must be
installed on a solid surface
such as a plywood floor
which must be the full width
and depth of the appliance.
Note: Unit must be installed onto a solid
backwall - do not install directly onto studs.
*C
Note : The framing depth does not take into
account drywall/wood or similar materials
against the back wall. The framing depth will
need to change based on the thickness of
the material (example: 20 5/8 framing depth
+ 1/2 drywall = 21 1/8")

HORIZONTAL TERMINATIONS
RIGID PIPE 4" X 6-5/8"
The minimum components required for a basic horizontal termination
are:
1 Power Vent Kit
1 Rigid Pipe Adaptor
1 Vent Reducer
1 Length of pipe to suit wall thickness and total vent run
(see Table 1)
Wall thickness is measured from the back standos to the inside mounting
surface of termination cap. Create a level surface to mount the vent
terminal. The Terminal must not be recessed into siding. Measure the
wall thickness.
