Figure 3-1. Installation Guidelines
Install the generator set, in its protective enclosure,
outdoors, where adequate cooling and ventilating air is
always available (
). Consider these factors:
•
The installation of the generator must comply
strictly with NFPA 37, NFPA 54, NFPA 58 and
NFPA 70 standards.
•
Install the unit where air inlet and outlet openings
will not become obstructed by leaves, grass, snow,
etc. If prevailing winds will cause blowing or
drifting, consider using a windbreak to protect the
unit.
•
Install the generator on high ground where water
levels will not rise and endanger it. It should not
operate in or be subjected to standing water.
•
Allow sufficient room on all sides of the generator
for maintenance and servicing. This unit must be
installed in accordance with any codes that are in
place in your country or local jurisdiction for
minimum distances from other structures.
•
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).

No operable windows or openings in the wall permitted
within 1.52 m (5 ft) from any point of the generator.

These guidelines are based upon fire testing of
the generator enclosure and the manufacturer’s
requirement for air flow for proper operation.
Local codes may be different and more restrictive
than what is described here.
Allow sufficient room on all sides of the
generator for maintenance and servicing.
Clearance from the ends and front of the
