1.2 Operating Safety
Familiarity and proper training are required for the safe operation of
this machine. Machines operated improperly or by untrained personnel
can be dangerous. Read the operating instructions contained in both
this manual and the OEM manuals included with this machine.

Inexperienced operators should receive instruction from someone
familiar with the machine before being allowed to operate it.
NEVER run the machine indoors or in an enclosed area unless
adequate ventilation, through such items as exhaust fans or hoses, is
provided. Exhaust gas from the genset and from the burner contains
carbon monoxide, a deadly poison. Exposure to carbon monoxide
WILL KILL YOU IN MINUTES.
Always use caution when applying power to the machine. Upon
applying power to the machine, the blower may start without warning.
1.2.1 Be sure the machine is on a firm, level surface and will not tip, roll,
slide, or fall while operating.
1.2.2 NEVER start a machine in need of repair.
1.2.3 Keep unauthorized personnel, children, and pets away from the
machine.
1.2.4 Always operate machine with all safety devices and guards in place
and in working order. Do not modify or defeat safety devices. Do not
operate machine if any safety devices or guards are missing or
inoperative.

2.1 System Description
The Cub 400 and Cub 700 heaters are indirect-fired air heaters. The
Cub 400 and 700 have stainless steel fireboxes and heat exchangers.
They run on three fuel options: diesel, natural gas (NG), or LP. The fuel
is consumed in a closed combustion chamber. The exhaust gases are
vented outdoors through a vent pipe. The clean, dry hot air is blown or
ciculated in the space by a centrifugal blower. The blower assembly is
protected by a guard fitted on the air inlet.
Cub 400 and Cub 700 heaters are meant to heat air on construction
sites and in other rugged applications. Do not use the Cub 400 or Cub
700 for any other purpose.

2.6 Preliminary Checks
Before starting the Cub 400 or Cub 700, check the following:
Fuel supply on diesel burning machines. See Fuel Blending
Guide.
Position of operation mode switch. It must be in the OFF (“0”)
position.
Power supply.Each machine must be connected to two (2) sepa-
rate power supplies adhering to specific requirements. Please
see the Technical Data tables in this manual for the specific
power requirements.
Note: On diesel burning machines, the fuel heater will begin
heating the fuel as soon as power is connected to the machine.
Thermostat plug/remote thermostat connection. Either the ther-
mostat plug or the remote thermostat cable must be connected in
order for the machine to operate.
2.7 Starting the Machine
2.7.1 If using the remote thermostat, place it in the area to be heated. Set it
to the desired temperature.
2.7.2 Turn the operation mode switch to
the HEAT position.
The blower will start immediately.
The burner will start. It will go through
a prepurge cycle and then light.
The burner will continue to fire until
the temperature of the space being
heated reaches the temperature set by the thermostat. At that time, the
burner shuts down but the blower will remain on.
Cub 400/700 Operation
wcghi_tx000683gb.fm 19
2.8 Preheating the Fuel Filter
In temperatures below 32°F (0°C), it may be necessary to preheat the
fuel inside the fuel filter canister. The fuel filter and nozzle contain low-
wattage heating elements that are controlled by a thermostat and are
specifically designed for this purpose.
Hot surface hazard.
The external surface of the fuel filter may be hot.
Wear safety gloves when handling the fuel filter.
Note: Excess heating may increase the need for maintenance. See
sections “Replacing the Fuel Filter” and “Replacing the Burner Nozzle”.
To preheat the fuel, carry out the following procedure.
2.8.1 Connect power to the machine. See section Connecting Power to the
Machine.
2.8.2 Wait 20-30 minutes—longer for colder temperatures.
2.8.3 Start the machine. See section Starting the Machine.
Note: In extreme wind, the machine may need to be temporarily
blocked from the wind in order to start.
2.8.4 If the burner does not start on the first attempt, allow the power-on
sequence to cycle again (see 3.10.3).
2.8.5 If, after the second power-on sequence completes, the machine will
not fire, move the power switch to the off position.
2.8.6 Wait another 20-30 minutes and attempt to start the machine again.
CAUTION
Operation Cub 400/700
20 wcghi_tx000683gb.fm
2.9 Shutting Down the Machine
2.9.1 Turn the operation mode switch to
the OFF (“0”) position.
The burner will shut down.
As soon as the air temperature
decreases to below approximately
104°F (40°C), the blower will stop.
Electric shock and cutting injury hazard! At temperatures above 104°F
(40°C), electric power is available at the supply blower even with the
operation mode switch in the OFF position. Always remove all power
to the machine before servicing it.
2.9.2 Once the blower has shut off automatically, disconnect the power
supply cord.
NOTICE: Do not disconnect the power supply cord until the blower has
cooled the heat exchanger and has shut off automatically.
2.9.3 Disconnect the remote thermostat and re-install the thermostat plug.
2.9.4 When using NG or LP gas, have a qualified and licensed technician
disconnect the gas supply.
