3.9.3 Single 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 opening 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 air discharge
opening, and the opening 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 3.18 shows the minimum required dimensions for the
single opening vented cavity air discharge opening. This single 3”
(height) x 53-1/2” (width) air discharge opening can be in either
on the front (access side) wall or the back (fixed side) wall of the
fireplace. Hot air will exit to the room where the air discharge
opening is located.
•
Figure 3.18 is shown with an air discharge overhang in front of
the air discharge opening. This optional installation method can
provide a means to visually hide the air discharge opening.
