1.10 Carburetor Heater (optional)

Have accessories installed by an authorized distributor/

dealer or a licensed electrician. Follow the installation

instructions provided with each kit. Use separate conduit

for AC and DC leads to reduce the possibility of electrical

interference. Verify that the leads and conduit do not

interfere with the operation of the generator set or

obstruct the service areas. Verify that the electrical

installation complies with the National Electrical Code

(NEC) and all applicable local codes. See Section 2,

Wiring Diagrams, for more information regarding

generator set electrical connections.

An optional 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). See Figure 1-23 through Figure 1-26.

The heater thermostat is installed in the cord.

Figure 1-26 shows the location of the thermostat on the

power cord.
