1.4.3 Exhaust Requirements
Figure 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 figure titled: Dimension Drawing ADV-8060, Sheet 3.

enclosure at rated kW, °C (°F)
Figure 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. Inspect the air inlet and outlet openings inside and outside the housing to ensure that
the air flow is not blocked.
1.5 Dimension Drawings
See the dimension drawings in the Installation Drawings section for the generator set dimensions, fuel and electric inlet locations,
and recommended clearance.
1.6 Fuel Requirements
The generator set operates using natural gas or LPG fuel. The generator set is EPA-certified for both natural gas and LPG fuels.
The fuel system installation must comply with the NEC and local codes.
1.6.1 Fuel Supply
Because of variable climates and geographical considerations, contact the local fuel supplier for fuel system planning and
installation. Figure 4 lists the recommended fuel ratings and other fuel supply information for natural gas and LPG fuels.

Fuel flow rate, maximum, Btu/hr.
Nominal Fuel Rating, Btu/ft.

Figure 4 Fuel Supply
Verify that the output pressure from the primary gas utility pressure regulator is as shown in Figure 4 and that the utility gas
meter flow rate is sufficient to supply the generator set at rated load plus all other gas-consuming appliances. For LPG tanks,
verify that the output pressure is as shown in Figure 4. See the figure titled: Fuel Consumption for fuel consumption. Contact the
fuel supplier for flow rate information or a gas meter upgrade.
The dimension drawings in the Installation Drawings shows the location of the fuel inlet connection. Use flexible sections to
prevent fuel line breakage caused by vibration. Protect all fuel lines from machinery or equipment contact, adverse weather
conditions, and environmental damage.
