If an open bottom is used, the engine-generator
is to be installed over non-combustible materi-
als and should be located such that combustible
materials are not capable of accumulating under
the generator set.
Only qualified, competent installation contractors
or electricians thoroughly familiar with applicable
codes, standards and regulations should install this
standby electric power system. The installation must
comply strictly with all codes, standards and regula-
tions pertaining to the installation.
After the system has been installed, do nothing
that might render the installation in noncompli-
ance with such codes, standards and regulations.

GENERATOR LOCATION
Install the generator set, in its protective enclosure
outdoors, where adequate cooling and ventilating air
always is available. Consider these factors:
• Install the unit where air inlet and outlet open-
ings 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.
• This genset must be installed on a level surface.
The base frame must be level within 1/2 inch all
around.
• Allow sufficient room on all sides of the generator
for maintenance and servicing. A good rule is to
allow five feet of space on all sides.
• Where strong prevailing winds blow from one
direction, face the generator air inlet openings into
the prevailing winds.
• Install the generator as close as possible to the
transfer switch. This reduces the length of wiring
and conduit.
• Install the generator as close as possible to
the fuel supply, to reduce the length of piping.
HOWEVER, REMEMBER THAT LAWS OR CODES
MAY REGULATE THE DISTANCE.
2.3
GENERATOR MOUNTING AND
SUPPORT
Retain the generator compartment to a concrete slab
with 1/4-inch masonry type anchor bolts. Be sure the
bolts are long enough to retain the compartment. The
slab should be at least six inches thick and should
extend beyond the enclosure to a distance of at least
three inches on all sides. See "Mounting Dimensions"
for generator major dimensions.
