The engine is equipped with an intake manifold grid heater. The grid heater
helps engine starting in cold weather. Intake manifold air temperature is
monitored by the Electronic Control Module (ECM) on the engine. If intake
manifold temperature is below specified level (approximately 40º F) manifold
grid heater will be activated. Grid heater activation is indicated by the WAIT
TO START indicator lamp.
WARNING: Use of ether starting fluids may cause an explosion upon
grid heater activation.
With the throttle at idle position, turn the ignition key to the ON position
allowing the WAIT TO START lamp to extinguish. Turn the key to the START
position. When the engine is started, the grid heater will again energize for a
time period determined by the intake air temperature and fuel temperature. Allow
the engine to idle with no load for three to five minutes. The engine coolant
temperature should be up to normal operating range
(140°F/60ºC to 212°F/100°C) before operating the engine under full throttle.
Starting and operating the motorhome during cold weather requires
extra care and consideration. Use the following guidelines and refer to
the OEM Engine Manual to help ensure safe, trouble-free operation of
the motorhome:

The Block Heater requires 120 Volt AC to operate. Hook to shore
power, as this is more efficient. The generator may be difficult to start
and the time required to pre-heat the engine may be lengthy. The block
heater receptacle is located inside the rear engine access doors along
the left side. The block heater is rated at 1000 watts.
An extension cord may be used, however, the power cord should
be rated at 15 Amps and the outlet used is GFCI protected rated at 20
Amps. The engine may require several hours of pre-heating prior to
starting. It is recommended to start pre-heating the engine the night
before departure. Remember to unplug the block heater before
departure.

To Use the Block Heater:

• Hook to a shore power receptacle and plug in the block
heater cord.
WARNING: All extension cords require a UL rating.
Use only a 15 Amp, 120 Volt AC extension cord.
NOTE: The inverter should never be used for the
power source. Rapid battery drain and inverter shut
down will occur.
