Ventilation Recommendations:
Dimensions below are minimum recommended for proper ventilation when the unit is in a recessed area.
NOTE:
The ventilation space should not be covered or closed off at the front of the opening. If for some reason the opening needs to be covered, other
means of ventilation will need to be incorporated into the design. Contact NEC for design review and recommendations.
