CLEARANCES CB72EPV
The clearances listed below are Minimum distances unless otherwise stated:
A major cause of chimney related res is failure to maintain required clearances (air space) to combustible materials. It is of the greatest importance that
this replace and vent system be installed only in accordance with these instructions.
Flue Clearances to Combustibles
Horizontal - Top 3"
Horizontal - Side 2"
Horizontal - Bottom 2"
Vertical 2"
Passing through wall/
floor/ceiling - when
restop is used.
1-1/2"
Note: This appliance uses 4" x 6-5/8" venting
Caution Requirements
The top, back and sides of the replace are dened by
stando󰀨s. The metal ends of the stando󰀨 may NOT be
recessed into combustible construction.
WARNING
Fire hazard is an extreme risk
if these clearances (air space) to combustible materials are not
adhered to. It is of greatest importance that this replace and vent
system be installed only in accordance with these instructions.
The HeatWave Duct Kit has
different clearance and framing
requirements, check the HeatWave
manual for details.

C* - see not in diagram below
** See next page for alternate Gas/ Electrical connection options
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
di󰀨erent methods as to how
this can be achieved.
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.
Ensure that the wood base that the appliance will sit on is strong enough to support the full weight of this 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")

CB72EPV Gas Fireplace
The gas power vent system is designed to allow the installation of a gas appliance when typical vent configurations (shown in this manual) are not
possible.
Note: The CB72EPV comes with a 5"inner and 8"outer collar which must be reduced to 4" x 6 5/8" in all applications. Must be terminated horizontally.
Vertical terminations are not permitted.
Important: Minimum overall vent run must be 4 feet.
Maximum total vent length = 72' maximum of six - 90° elbows permitted.
One 90° elbow = two 45° elbows.
Maximum total negative vent length = 7'.
Note: Maximum length of 72 feet is based on overall length of combined chimney
components.
VENTING ARRANGEMENTS FOR HORIZONTAL TERMINATIONS
RIGID PIPE: MUST USE RIGID PIPE ADAPTOR 770-994 AND 946-606 PIPE REDUCER TO 4" X 6 5/8"
Note: Rigid pipe is approved for up to 72 feet.
FLEX VENT: MUST USE REDUCER 946-758 TO 4" X 6 5/8"
Note: Flex pipe is approved for up to 40 feet using 2 X 946-756-- 20 foot ex kits.

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 stando󰀨s 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.
