Clearance from the ends and front of the
generator must be 3 ft (0.91 m). This includes
shrubs, bushes and trees. Clearance from the
back of the generator must be a minimum of 18
in (457 mm). Clearance at the top should be a
minimum of 5 ft (1.52 m) from any structure,
overhang or projections from the wall.
DO NOT install under wooden decks or
structures unless there is at least 5 ft (1.52 m)
of clearance above the generator.
