Magic-pac MHP4 Series Installation And Maintenance Instructions Manual page 3

Clearance to combustible materials is 0" at the side, top, and front of plenum. If accessibility clearances are greater
than clearances to combustibles, accessibility clearances take precedence.
The front of the unit must be accessible for service. If the unit is enclosed, providing a door or access panel opposite
the front of the unit is the preferred method of providing access. The door or access panel must be at least 30" wide
(centered on the unit) and as tall as the unit. If a return duct is not installed, in order to provide adequate return air the
minimum clearance required between the front of the unit and the door or access panel is 4" for 43" tall cabinets and 5"
for 48" and 56" tall cabinets.

the drain trap installation.
