3.8.3 Top Vented Cavity Option
WARNING: Enclosure measurements must maintain minimum
framing specs as outlined in section
3.5, ROUGH FRAMING
(page
15). Minimum dimensions for the air discharge opening MUST BE
maintained after all finishing materials are installed.
NOTE: The top vented cavity option allows the use of 19 gauge (or less)
1/2” x 1/2” hardware mesh 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 air discharge
opening area. Grilles and louvers are NOT allowed.
WARNING: Failure to comply with these instructions could create
a fire hazard. Ensure air flow within the air discharge opening is not
restricted in any way.
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
for aesthetic purposes and to avoid items falling into the enclosure.
