A: In accordance with local codes
For multiple-unit rooftop terminations, space all exhaust and intake terminations in accordance with local
codes. An exhaust termination must be spaced from a wall or surface in accordance with local codes as
well. In the absence of such a code, an exhaust termination must be a horizontal distance of at least 2 ft.
(61 cm) away from a wall or surface.
Please follow all local and national codes in regards to proper termination
clearances. In the absence of such codes, the above clearances can be used as

are less restrictive. In such cases, the minimum clearances listed in this manual
