OPERATION

REVIEW AND UNDERSTAND ALL WARNINGS IN THIS MANUAL. THEY ARE
ESSENTIAL FOR SAFE USE OF THE HEATER. FOLLOW ALL LOCAL CODES.

To start heating:

1. Place the heater on a stable, level surface. Make sure that no explosive or combustible fumes
or dust are present. See that the heater is not exposed to water spray, rain, or dripping water.

Minimum clearances from combustible materials:

Outlet: 6 feet, Sides: 1 foot, Top: 2 feet, Rear: 2 feet

Floor: combustible

2. Connect heater to proper power source. The P600 requires a 240V, 60Hz single phase 25 Amp
power source. The P900 requires a 240V, 60Hz single phase, 40 Amp power source. The
P1800-1 requires a 240V, 60 Hz single phase, 75 Amp power source. The P1800-3 requires a
240V, 60 Hz three phase, 50 Amp power source. The P4000 requires a 480V, 60 Hz three
phase, 50 Amp power source. The P6000 requires a 480V three phase, 75 Amp power source.
Also, ALL POWER SOURCES NEED TO BE EQUIPPED WITH A CIRCUIT BREAKER!

Note: When power is first applied to unit, the heater fan may blow
air out of heater INLET. If this condition occurs, (after first
removing power from cord) reverse the first two hot wires at heater
terminal inlet block. (3 Phase Models Only)

3. Set the remote thermostat to a temperature above the ambient room temperature by turning
the knob. NOTE: The heater will start only if the thermostat “calls for heat” meaning that it is
set to higher than prevailing ambient temperature.

4. Set the selector switch to the desired heating setting. For the P1800 series, the options are #1
for ventilation (fan only), #2 for low heat output of 12Kw (41,000 Btu’s), or #3 for high
output of 18Kw (65,000 Btu’s).

For the P4000, the switches are labeled S1 with a heat output of 16Kw (54,600 Btu’s), S1 and
S2 with a heat output of 32Kw (109,200 Btu’s) or S1, S2 and S3 with a heat output of 40Kw
(136,000 Btu’s).

For the P6000, the switches are labeled S1 with a heat output of 24Kw (81,900 Btu’s), S1 and
S2 with a heat output of 48Kw (163,800 Btu’s) or S1, S2 and S3 with a heat output of 60Kw
(204,700 Btu’s).

The heater will now operate automatically, controlled by the thermostat.

5

To Stop Heating: (P1800, P4000, P6000)

1. Turn all switches to “Off”.

2. Allow fan to run until unit stops automatically, controlled by unit cooldown thermostat (fan
switch). Heater may cycle more than once.

3. Unplug the power supply cable after the fan has stopped cooling down the heater completely.

To Stop Heating: (P600, P900)

1. Reduce ambient (room) thermostat to “Heat Off” position.

2. Allow fan to run for at least two minutes.

3. Flip switch to “Off” position.

4. Unplug heater.

NOTE: The heater is equipped with an overheat limit switch which may cause the heater to
stop. Check and remove the cause for overheating before re-starting.

Never disconnect supply plug to stop the heater while in operation!!

MAINTENANCE

Never service heater while it is plugged in, running or hot. Severe bodily injury or electric
shock may occur.

Only qualified persons are allowed to open heater for service.

1. Keep heater clean (ex. dry wall dust). Use pressurized air to blow fan blades clean.
NOTE: Use moderate pressure to avoid damage to fan blades.

2. Inspect heater before and after each use.

3. The bearings of the fan motor are permanently lubricated and sealed No additional lubrication
is needed.

GENERAL ELECTRIC HEATER SIZING ISSUES

When running Heat Wagon electric heaters from a generator, it is extremely important to make sure
that the generator selected for your heater is not undersized. The single largest service issue with
Heat Wagon electric heaters is improper set up relating to inadequate voltage due to too small of an
electric source and/or too small of a power cord.

Generator Selection for Heat Wagon Electric Heaters

The chart below will help you when it comes to selecting the correct generator required for your
Heat Wagon heater:

Model Watts Phase BTU'S Volts Amps CFM Recommendations

P1500 1,500 1 Phase 5,100 120 15 120 3KW
P600 6,000 1 Phase 20,500 240 25 250 10KW
P900 9,000 1 Phase 30,700 240 38 350 15KW
P1800-1 18,000 1 Phase 64,000/41,000 240 75 590 25KW
P1800-3 18,000 3 Phase 64,000/41,000 240 50 590 25KW
P1800D 18,000 3 Phase 64,000/41,000 240 50 950 25KW
P4000 40,000 3 Phase 136,000/109,200/54,600 480 50 1,800 50KW
P6000 60,000 3 Phase 204,700/163,800/81,900 480 70 1,800 75KW

So, by reviewing the above chart, a P1800-1 would require a minimum 18,000 Watt (18KW),
240 volt single phase generator that can provide 75 amps of continuous power.
