Unit Panels

After performing any maintenance or service on the unit, be sure all
panels are fastened securely in place to prevent rain from entering unit
cabinet and to prevent disruption of the correct unit airflow pattern.
Combustion Area and Vent System
For proper and safe operation, the unit needs air for combustion and
ventilation. The air openings, on the unit, the air openings to the area in
which the unit is installed, and the spacing around the unit must not be
blocked or obstructed.
