Chapter 1
Introduction to Heater
Mounted at eye level on the trailer, you will see a small gray box with a clear cover, the
control box, like that shown in figure 3. When you lift the cover you will see a rocker
switch and two indicator lights. The rocker switch turns the heater on and off, the top
(green) indicator lights when the heater is getting
power, and the bottom (red) indicator lights when
the ignition system is unsuccessful in lighting the
heater (See the section on troubleshooting).
You may also have the optional 110V standby
power supply (see figure 4) connected to the heater.
This unit allows you to run the unit by plugging it in
to a standard outlet, allowing you to run the heater
without attaching the trailer to a semi tractor or to run the heater through the night
without running down your vehicle’s battery.
