1.11.1 GENERATOR
Install the generator set, in its protective enclosure, outdoors ,
where adequate cooling and ventilating air is always available
(Figure 1.3). 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 wind-
break to protect the unit.
Install the generator on high ground where water levels will not •
rise and endanger it.
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.
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.
Figure 1.3 – Generator Clearances
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.
1.11.2 NEW INSTALLATION GUIDELINES FOR
STATIONARY AIR-COOLED 7KW GENERATORS.
The National Fire Protection Association has a standard for the
installation and use of stationary combustion engines. That
standard is NFPA 37 and its requirements limit the spacing of an
enclosed generator set from a structure or wall (Figure 1.10).
NFPA 37, Section 4.1.4, Engines Located Outdoors. Engines, and
their weatherproof housings if provided, that are installed outdoors
shall be located at least 5 ft. from openings in walls and at least 5
ft. from structures having combustible walls.
Generator exhaust contains DEADLY carbon monoxide gas. This
dangerous gas can cause unconsciousness or death. Do not place
the unit near windows, doors, fresh air intakes (furnaces, etc.) or
any openings in the building or structure, including windows and
doors of an attached garage.
1.11.3 TRANSFER SWITCH
The transfer switch that shipped inside the carton with the genera-
tor is enclosed in a NEMA 1 (indoor rated only) enclosure.
Install the transfer switch indoors on a firm, sturdy supporting •
structure.
To prevent switch distortion, level the switch if necessary. This •
can be done by placing washers between the switch enclosure
and mounting surface.
Never install the switch where water or any corrosive substance •
might drip onto the enclosure.
Protect the switch at all times against excessive moisture, dust, •
dirt, lint, construction grit and corrosive vapors.

If the AUTO/OFF/MANUAL switch is not set
to its OFF position, the generator can crank
and start as soon as the battery cables are
connected. Sparking can occur at the battery
posts and cause an explosion.
