TP-6516 4/0926 Section 1 Installation
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.

The heater requires a continuous source of 120 VAC
power. The heater power cord and thermostat are
located in the generator set housing air intake area/
battery compartment. See Figure 1-22 and
Figure 1-24. Plug the carburetor heater into an outlet
that supplies continuous 120 VAC power.
Note: Do not place the heater thermostat inside the
generator set engine compartment. The
thermostat must be exposed to the ambient air.
Thermostat will shut off power to the heater when
ambient temperature reaches approximately
16_C (60_F).
Figure 1-25 shows the location of the carburetor heater
on the 17/18 kW generator set engine for reference.
(The engine has been removed from the generator set in
this photo for a clear view.)
