NOTE:
It is essential to use the latest version of any stan-
dard to ensure that the generator and its accesso-
ries comply with all the applicable standards and
local codes.
The installer must comply with all applicable state
and local codes.
1.3 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. 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.
• 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.
1.4 GENERATOR MOUNTING AND
SUPPORT
A CONCRETE BASE:
When designing a concrete base slab, all federal, state
and local codes should be followed. Special atten-
tion 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.
Retain the generator compartment to the concrete
slab with masonry bolts.
‹ 1.4.1 COMBUSTIBLE FLOOR AND ROOF
PROTECTION
If the generator must be installed on any combustible
floor or roof, comply with the following rules:
• Place a layer of non-combustible insulation, fol-
lowed by a layer of sheet metal beneath the unit’s
mounting base rails (Figure 1.1).
• Both the layer of insulation and the sheet metal
must extend beyond the generator base to a dis-
tance of at least 12 inches (30.5 cm) on all sides.
Figure 1.1 — Combustible Floor and Roof
Protection
For rooftop or building structure mounting, it is rec-
ommended that spring isolators be installed between
the engine frame and the mounting system. A mini-
mum of six (6) isolators are required and must be
located at the front and rear cross members and the
center of the frame.
Since the entire bottom of the genset is now exposed,
it should be covered with a metal plate to keep out
small animals and protect the integrity of the internal
parts of the genset. Genset movement is more intense
with spring isolation, so flexible connections for the
fuel and the electrcal conduits are also required.
NOTE:
Consult the local building codes which may vary.
