3.9.4 Dual Opening Vented Cavity Option
NOTE: This vented cavity option allows the use of 19 gauge or less
hardware mesh that is 1/2” x 1/2” to prevent any items from entering
the vented cavity. This hardware mesh is optional and the only
approved item for use within the air discharge opening.
WARNING: Do NOT cover or place any items in the area of the air
discharge opening. Failure to comply with these instructions could
create a fire hazard. Grilles and louvers are not allowed in the discharge
opening.
WARNING: Ensure air flow within the air discharge openings is not
restricted in any way.
WARNING: Enclosure measurements must maintain minimum framing
specifications for full enclosure framing as outlined in Section 3.5.2
Rough Framing on page 18. Shelf enclosure framing is not allowed for
vented cavity installations. Minimum dimensions for the air discharge
MUST BE maintained after all finishing materials are installed.
These are minimum dimensions shown for the dual air discharge
openings, and the openings may be increased, if desired, as long
as all requirements are followed. It is recommended to limit your
opening size for aesthetic purposes and to avoid items falling into the
enclosure.
•
Figure 3.22 shows the minimum required dimensions for the
dual opening vented cavity air discharge openings.
The dual
1-1/2” (height) x 63-1/2”
(width) air discharge openings
are best
for installations where the fireplace is dividing two rooms.
•
Figure 3.22 is shown with air discharge overhangs in front of the
air discharge openings. This optional installation method can
provide a means to visually hide the air discharge openings.
