Starting and Stopping the Engine
We recommend that you do the
following for a safe and correct
operation:
• Use a 16-gauge outdoor extension
cord that is product certified by
Underwriter's Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must
be suitable for use outdoors, in
cold temperatures, and be clearly
marked Suitable for Use with
Outdoor Appliances. Do not use an
indoor extension cord outdoors.
This could result in an electric
shock or become a fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension
cords.
• Make sure that when in operation,
the extension cord plug and heater
cord plug connections are free and
clear of water. This could cause an
electric shock or fire.
• Make sure your vehicle is parked in
a clean area, clear of
combustibles.
• Make sure the heater, heater cord
and extension cord are firmly
connected.
• Check for heat anywhere in the
electrical hookup once the system
has been operating for
approximately 30 minutes.
• Make sure the system is unplugged
and properly stowed before driving
your vehicle. Make sure the
protective cover seals the prongs
of the block heater cord plug when
not in use.
• Make sure the heater system is
checked for proper operation
before winter.
Using the Engine Block Heater
Make sure the receptacle terminals
are clean and dry prior to use. Clean
them with a dry cloth if necessary.
The heater uses 0.4 to 1.0
kilowatt-hours of energy per hour of
use. The system does not have a
thermostat. It achieves maximum
temperature after approximately
three hours of operation. Using the
heater longer than three hours does
not improve system performance and
unnecessarily uses electricity.
