Ventilation Openings
Regency's patented Cool Wall system releases warmth at ceiling level. This
system reduces excessive radiant heat in front of the fireplace so you can
enjoy your fireplace 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 120
square inch opening & is located 0-3" (76mm) 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 flow. 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 120 square inches of free open area.
Example: 6" (152mm) wide x 10" (254 mm) High = 60 square inches of free
open area. A second ventilation grill is installed in front to =100%.
The ventilation openings must be located 0-3" 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 is measured from top of enclosure
to the ceiling and must be in open in front and side to meet the minimum
120 square inches free open air requirement.
Ventilation Opening Locations
The following are examples of how the ventilation openings may be placed
above the fireplace.
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 120
square inches regardless.
The air travelling through the heat exchanger is heated by the fireplace and
then directed out the back of the fireplace. 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 120
square inch opening. This type of ventilation opening would be used
when the top of the enclosure is visible from above and where the ceiling
within the room is higher than normal.
