Generator Location

WARNING
Exhaust heat/ gases can ignite combustibles or
structures causing a fire.
• DO NOT install the generator closer than 5 feet (1.5m) from any
combustibles or structures with combustible walls having a fire
resistance rating of less than 1 hour.
• Keep at least 3 ft. (91 cm) clearance on all sides of generator
including overhead.
Before installing generator, consult with homeowner and
convey the following guidelines which may affect the desired
location.
Install generator outdoors in an area which will not
accumulate deadly exhaust gas. DO NOT install generator
where exhaust gas could accumulate and enter inside or be
drawn into a potentially occupied building. Ensure exhaust
gas is kept away from any windows, doors, ventilation
intakes or other openings that can allow exhaust gas to
collect in a confined area (Figure 1). Prevailing winds and air
currents should be taken into consideration when positioning
generator.
WARNING
Running engine gives off carbon monoxide, an
odorless, colorless, poison gas.
Breathing carbon monoxide can cause headache,
fatigue, dizziness, vomiting, confusion, seizures,
nausea, fainting or death.
• Operate generator ONLY outdoors.
• Install a battery operated carbon monoxide alarm near the
bedrooms.
• Keep exhaust gas from entering a confined area through
windows, doors, ventilation intakes, or other openings.

General Location Guidelines
• Install the unit outdoors ONLY.
• Place the unit in a prepared location that is flat and has
provisions for water drainage.
• Install the unit in a location where sump pump
discharge, rain gutter down spouts, roof run-off,
landscape irrigation, or water sprinklers will not flood
the unit or spray the enclosure and enter any air inlet
our outlet openings.
• Install the unit where the location of any services such
as phone, electrical, fuel, air conditioning, irrigation,
including covered, concealed and underground services
will not be affected or obstructed.
• 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, you may
need to construct a windbreak to protect the unit.
• Install the generator as close as possible to the Transfer
Switch to reduce the length of wiring and conduit.
• Install the generator as close as possible to the fuel
supply to reduce length of pipes.
IMPORTANT: Laws or local codes may regulate the distance
to the fuel supply.
The generator system is shipped already attached to its
mounting pad. Unless mandated by local code, a concrete
slab is not required.
If mandated by local code, construct a concrete slab at least
3 inches thick and 6 inches longer and wider than the unit.
Attach unit to slab with 1/4" diameter (minimum) masonry
anchor bolts long enough to retain the unit.
