Ventilation Openings (Three-sided/Bay Installation)
Regency's patented Cool Wall system releases warmth at ceiling level. This
system reduces excessive radiant heat in front of the replace so you can
enjoy your replace more often.
• Design your own chase vent solution to suit your home
• Use optional front or left & right side chase vent grills
• Release warmth into the room discreetly
Front Exit
The ventilation opening may be placed in front ensuring it meets the 288
square inch opening & is located 0-2" (51mm) from the enclosure ceiling.
SIde Exit (Left/Right)
Ventilation openings, when placed on both sides, must be of the same size.
They must be have an equal split (50/50) free air opening to balance air ow.
A ventilation opening may never be on one side only.
The ventilation openings cannot be any smaller than 6" (152mm) wide to
equal the total area of 288 square inches of free open area.
Example: 6" (152mm) wide x 24" (610mm) High = 144 square inches per
side of free open area. A second ventilation grill is installed on the other side
to =100%.
The ventilation openings must be located 0-2" (51mm) from the enclosure
ceiling.
Top Exit
The ventilation opening may be short of the ceiling as shown below.
Minimum opening height must be 2-1/2" (64mm) measured from top of
enclosure to the ceiling and must be in open in front and both sides to
meet the minimum 288 square inches free open air requirement.
Ventilation Opening Locations
The following are examples of how the ventilation openings may be placed
above the replace.
If using the optional heat wave kit, this does not reduce the size of the
ventilation opening. The ventilation opening(s) must be a minimum 288
square inches regardless.
The air travelling through the heat exchanger is heated by the replace and
then directed out the back of the replace. The combined warmed air is then
vented back into the room.
The ventilation opening may be fully open at the top of the enclosure.
This type of ventilation opening would be used when the top of the
enclosure is not visible from above and where the ceiling within the
room is higher than normal. When creating this type of ventilation
opening, measures should be into place to avoid having objects of any
type falling or be thrown into the ventilation opening. Mesh screen or
other preventative measures should be put into place.
The ventilation opening may be placed on top ensuring it meets the
288 square inch opening. This type of ventilation opening would be used
when the top of the enclosure is visible from above and where the ceil-
ing within the room is higher than normal.
NOTE
• For right/left two-sided corner, see next page.

Front Exit
The ventilation opening may be placed in front ensuring it meets the 288
square inch opening & is located 0-2" (51 mm) from the enclosure ceiling.
Side/Front Exit
Ventilation openings, when placed on the side, must also have the same size
ventilation opening in front. They must be have an equal split (50/50) free
air opening to balance air ow. A ventilation opening may never be on one
side only.
The side ventilation opening cannot be any smaller than 6" (152mm) wide to
equal the total area of 288 square inches of free open area.
Example: 6" (152mm) wide x 24" (610mm) High = 144 square inches of free
open area. A second ventilation grill is installed in front to =100%.
The ventilation openings must be located 0-2" (51 mm) from the enclosure
ceiling.
Top Exit
The ventilation opening may be short of the ceiling as shown below.
Minimum width/depth of chase x height measured from top of enclosure
to the ceiling and must be in open in front and side to meet the minimum
288 square inches free open air requirement.

When choosing to install the ventilation openings from the front or both sides, The top of the ventilation opening cannot be any lower than 0-2" (51mm)
from the top of the chase enclosure for all installations.
Minimum height of enclosure from base of appliance is 87" (2210mm).
A minimum 288in2 opening in the enclosure is required to maintain safe operating temperatures. This can be achieved in a number of ways including the
examples shown in this manual.
IMPORTANT:
Exterior wall/Alcove enclosure: When installing into an exterior cavity or alcove enclosure (ceiling, back and sides), regardless of where appliance is
placed within the home, requires the use of either drywall or other means such as plywood, wood studs, etc. to prevent heat from escaping anywhere above
/through the enclosure other than the required grill / ventilation opening.
Internal chase: When installing as an internal chase framing installation ,regardless of where appliance is placed within the home, requires the use of either
drywall or other means such as plywood, on the rear wall of the chase to eliminate heat escaping into the rear wall cavity. If the chase is extended to the
ceiling ,the ceiling will also need to be nished in a manner to prevent heat escaping into oor joist/attic space.
One of the following methods must be used to prevent the heat from escaping.
a. If choosing drywall, ensure that the drywall is butt up tight with no gaps.
b. Plywood, wood studs, etc. installed tightly with no gaps.
As this appliance has been designed with all hot air escaping through the chase enclosure ventilation/grill openings only, if hot air is trapped as a result of
the hot air escaping through joints, crevasses, open studs, or other openings within the enclosure above, this will change the clearances within the enclosure
causing the enclosure to overheat. It is vital that all the hot air from within the enclosure exits through the ventilation openings only.
Ensure that the ventilation openings are made as such to prevent debris, objects from falling into the enclosure.
Warning: DO NOT cover or place objects in front of the ventilation opening air outlet(s).

Clearances - Bay Install
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
dierent clearance and framing re-
quirements, check the HeatWave
