2.5 Carburetor Heater
Hot engine and exhaust system.
Can cause severe injury or death.
Do not work on the generator set until
it cools.
WARNING
Servicing the engine heater. Hot parts can cause minor
personal injury or property damage. Install the heater
before connecting it to power. Operating the heater before
installation can cause burns and component damage.
Disconnect power to the heater and allow it to cool before
servicing the heater or nearby parts.
A carburetor heater is recommended for improved cold
starting in locations where the ambient temperature
drops below 0_C(32_F). The carburetor heater
prevents condensation and carburetor icing. The heater
turns on when the temperature at the thermostat falls
below approximately 4_C(40_F) and turns off when the
temperature rises above approximately 16_C(60_F).
The carburetor heaters are shown in Figure 2-9.
To install the carburetor heater, follow the instructions
provided with the kit. Figure 2-10 shows the installed
carburetor heater kit installed for a 14 kW generator set.
Figure 2-11 shows the location for the carburetor heater
kit on a 20 kW generator set.
Verify that AC power is connected to the generator set
as described in Section 1.9. The circuit must be backed
up by the generator set to provide power at all times.
The heater thermostat is installed in the cord.
Figure 2-9 shows the location of the thermostat on the
power cord. The heater power cord and thermostat are
located in the generator set housing air intake area/
battery compartment.
For 120 volt models, plug the carburetor heater into one
of the 120 VAC receptacles provided.
240 volt kits use a 3-pin power connector. Generator
sets built after 10/9/2013 have a knockout in the
bulkhead for the 240 VAC power connector. See
Figure 2-12.
