1.11.1 GENERATOR
Install the generator set, in its protective enclosure, outdoors,
where adequate cooling and ventilating air is always available
(Figure 1.9). Consider these factors:
•
The installation of the generator
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 wind-
break to protect the unit.
•
Install the generator on high ground where water levels will not
rise and endanger it.

must comply strictly with
•
Allow sufficient room on all sides of the generator for mainte-
nance and servicing. This unit must be installed in accordance
with current applicable NFPA 37 and NFPA 70 standards; as
well as any other federal, state and local codes for minimum
distances from other structures. DO NOT install under wooden
decks or structures unless there is at least four (4) feet of clear-
ance above the generator, three (3) feet of clearance on sides
and front, and 18 inches of clearance at back of unit.
•
Install the unit where rain gutter down spouts, roof run-off,
landscape irrigation, water sprinklers or sump pump discharge
does not flood the unit or spray the enclosure, including any air
inlet or outlet openings.
•
Install the unit where services will not be affected or obstructed,
including concealed, underground or covered services such as
electrical, fuel, phone, air conditioning or irrigation.
•
Where strong prevailing winds blow from one direction, face the
generator air inlet openings to the prevailing winds.

•
Install the generator as close as possible to the fuel supply, to
reduce the length of piping.
•
Install the generator as close as possible to the transfer switch.
REMEMBER THAT LAWS OR CODES MAY REGULATE THE
DISTANCE AND LOCATION.
•
The genset must be installed on a level surface. The base frame
must be level within two (2) inches all around.
•
The generator is typically placed on pea gravel or crushed
stone. Check local codes if a concrete slab is required. If a
concrete base slab is required, all federal, state and local codes
should be followed. Special attention should be given to the
concrete base slab which should exceed the length and width
of the generator by a minimum of six (6) inches (0.152 meters)
on all sides.
