TP-7091 2/21 13Section 1 Location and Mounting
1.4 Location and Mounting
Install the generator set outdoors near the incoming gas
service. The generator set location must allow easy
access for maintenance and service. The required
distance from a structure is dependent on state and
local codes. See the dimension drawing in Section 6 for
the minimum clearance from structures and
non-combustible materials.
Locate the generator set so that the hot exhaust does
not blow on plants or other combustible materials. No
plants, shrubs, or other combustible materials are
allowed within 1.2 m (4 ft.) of the exhaust end of the
generator set.
Do not install the generator set where exhaust gas could
accumulate and seep inside or be drawn into a
potentially occupied building. Furnace and other similar
intakes must be at least 3 m (10 ft.) from the exhaust
end of the generator set.
WARNING
DO NOT locate the generator set near patios, decks,
play areas, or animal shelters. Keep items such as
lawn furniture, toys, sports equipment, and all
combustible materials away from the generator set
exhaust outlet.
Remind family members, children, and visitors to use
caution near the generator set. Generator sets
connected to automatic transfer switches start
automatically during exercise periods and power
outages. Some generator set components become
hot when the generator set is running and remain hot
for a time after the generator set shuts down.
1.4.1 Mounting Area
Prepare the generator set mounting area. The
mounting area must:
 Provide a flat, level surface for the generator set.
 Allow easy access for maintenance and service.
 Support the weight of the generator set with related
equipment, such as the battery and mounting pad.
 Support the generator set weight for the lifetime of the
generator set.
 Meet applicable building codes.
 Not be subject to flooding.
Clear all combustible materials, including plants and
shrubs, building materials, and lawn furniture, from an
area at least 1.2 m (4 ft.) beyond the exhaust end of the
generator set. See the dimension drawing in Section 6.
The generator set is shipped on an aluminum base. Set
the base directly on the mounting area or on an optional
concrete mounting pad.
1.4.2 Exhaust Requirements
Figure 1-3 gives the exhaust temperature at rated load.
The engine exhaust mixes with the generator set
cooling air at the exhaust end of the enclosure. Mount
the generator set so that the hot exhaust does not blow
on plants or other combustible materials. Maintain the
clearances shown in the dimension drawing in
Section 6.

Figure 1-3 Exhaust Flow and Temperature
The generator set requires correct air flow for cooling
and combustion. The inlet and outlet openings in the
sound enclosure provide the cooling and combustion
air. Figure 1-4 shows the locations of the cooling air
intake and exhaust vents. Inspect the air inlet and outlet
openings inside and outside the enclosure to ensure
that the air flow is not blocked.
