Generac Power Systems PowerPact 6561 Installation Notes page 12

DO NOT install under wooden decks or
structures unless there is at least four (4)
feet of clearance above the generator,
three (3) feet of clearance on sides and
front, and 18 inches of clearance at back of
unit. This would include trees, shrubs and
vegetation that could obstruct airflow.
And the internet say's - Under a deck? ....
No No No!
I guess Koehler's don't need air flow.
This one may be ok, but ugly ... but then look at the Service
Entrance NEMA-3R Switch.
