GM51561

Generator set operation. Carbon monoxide can cause severe nausea, fainting, or death. Carbon monoxide is an odorless, colorless, tasteless, nonirritating gas that can cause death if inhaled for even a short time. Avoid breathing exhaust fumes when working on or near the generator set. Never operate the generator set inside a building. Never operate the generator set where exhaust gas could seep inside or be drawn into a potentially occupied building through windows, air intake vents, or other openings.

The exhaust system is complete for generator sets installed outdoors. Do not install this generator set indoors.

Figure 1-6 gives the exhaust flow and 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 Figure 1-5.

1.4.2Air Requirements

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 1-7 shows the locations of the cooling air intake and exhaust vents. Inspect the air inlet and outlet openings inside and outside the housing to ensure that the air flow is not blocked.

1.5 Power Supply

Power must be supplied from a source that is GFCI protected to the generator set location for the battery charger and the optional carburetor heater. See Section 1.8. Connect power from a circuit on the essential loads panel to the 120-VAC receptacles. Figure 1-9 lists the power requirements for the battery charger and accessories.

	Power Requirement, Max.
Equipment	Watts	Amps	Volts
Battery charger	192	1.6
Carburetor heater:
12 kW	38	0.32	120
17/18 kW	40	0.34
Battery heater	110	0.92
