The HeatWave Duct Kit has
different clearance and framing
requirements, check the HeatWave
manual for details.
Caution Requirements
The top, back and sides of the fireplace are defined by
standoffs. The metal ends of the standoff 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.

FRAMING DIMENSIONS CB40EPV
NOTE: Framing may be constructed of combustible material (ie. 2x4) and does not require steel studs. Two (2) optional steel stud kits may also
be purchased. These kits may be used in place of the conventional wood framing as shown below. It comes as a compact kit (flush to the
appliance on all sides)or an extended kit. The extended kit protrudes beyond each side of the appliance as shown on the front cover of
this manual. There is also an optional hearth kit which may be purchased as shown on the front cover of this manual. These kits are highly
recommended as it was designed specifically for the product to facilitate ease of installation. See instructions in this manual for details.
Framing
Dimensions
A Framing Height 37-3/8” (949mm)
B Framing Width 48-1/2" (1232mm)
C Framing Depth 19" (483mm)
D Minimum Height to Combustibles 63"(1600mm)
G Vent Centerline Height 56-1/4" (1429mm)
I Gas Connection Opening Height 2" (51mm)
J Gas Connection Height 4 " (106mm)
K Gas Connection Inset 13" (330mm)
L Gas Connection Opening Width 3-1/2" (89mm)
Note: A combined minimum of 120 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 CB40E in the unit manual as there are different methods as to how this can be achieved.
Note: Only basic framing dimensions are shown. The framing may also extend beyond the appliance on either side and also extend out front if a
hearth is desired. See clearance/finishing requirements for details.
Note: Unit is not load bearing. All finished materials must be supported by framing.

MANTEL CLEARANCES CB40EPV
Due to the extreme heat this fireplace emits, the
mantel clearances are critical.
Combustible mantel clearances from top of front facing
are shown in the diagram on the right.
Note: Ensure the paint that is used on the mantel
and the facing is "high quality" or the paint
may discolour.

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 Length of pipe to suit wall thickness and total vent run
(see Table 1)
Wall thickness is measured from the back standoffs 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.
