3.11.4 Top Vented Cavity Framing
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: Minimum dimensions for the air discharge MUST BE
maintained after all finishing materials are installed.
