Heat Wagon P1800D Electric Heater

IMPORTANT INSTRUCTIONS

READ ALL INSTRUCTIONS BEFORE USING THIS HEATER

1. This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. Use handle when moving this heater. Keep combustible materials at least 6 feet (2 meter) from the front of the heater and keep them away from sides and rear
2. Extreme caution is necessary when the heater is used near children or invalids and whenever the heater is left unattended
3. Always unplug the heater when not in use
4. Do not operate any heater with a damaged cord or plug or after the heater malfunctions, has been dropped or damaged in any manner. Return heater to authorized service facility for examination, electrical or mechanical adjustment or repair
5. Do not use outdoors
6. This heater is not intended for use in bathrooms, laundry areas and similar indoor locations. Never locate the heater where it may fall into a bathtub or other liquid container
7. Do not run cord under carpeting. Do not cover cord with throw rugs, runners, or the like. Arrange cord away from traffic area and where it will not be tripped over
8. TO DISCONNECT HEATER, reduce ambient thermostat to zero. Fan will continue to run (P1800,4000,6000) until unit cools and shuts down automatically, turn switches off, disconnect power. For P600, P900 let fan run one minute then after cooldown, turn switch off, disconnect power.
9. Connect to properly grounded outlets only
10. Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an electric shock or fire, or damage the heater
11. To prevent a possible fire, do not block air intakes or exhaust in any manner. Do not use on soft surfaces, where openings may become blocked
12. A heater has hot and arcing or sparking parts inside. Do not use in areas where gasoline, paint or flammable liquids are used or stored
13. Do not point to flammable materials
14. Use heater only as described in this manual. Any other use not recommended by the manufacturer may cause fire, electric shock or injury to persons
15. Always plug heaters directly into a wall outlet/receptacle. Never use with an extension cord or relocatable power tap (outlet/power strip)
16. SAVE THESE INSTRUCTIONS

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:

2. Outlet: 6 feet,

3. Sides: 1 foot,

4. Top: 2 feet,

5. Rear: 2 feet

6. Floor: combustible

7. 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)

8. 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.

9. 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.

• 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:

• 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.

ELECTRICAL CORD SELECTION FOR HEAT WAGON ELECTRIC HEATERS

Once you have established that you have enough power to properly run a Heat Wagon Electric Heater, you still need to deliver the power to the heater adequately. You will need to do a Voltage Drop Formula. The Voltage Drop Formula is amps (source), times resistance (cord’s wire size) equals voltage drop. A cords wire size resistance chart is below:

• Example: P1800-1 phase 75 amp
• Minimum Voltage Required=208V
• 150 ft. x 12 gauge wire (0.00162) = .24
• 75 amps x .24 = 18.0 volt drop
• 220v (at source) – 18v = 202 volts
• Conclusion: Heater will not run, wire too small or cord too long.

Options to Correct the Situation:

1. Increase gauge of wire: If you increased your wire 6 gauge wire, then your formula would be as follows:
   • Example: P1800-1 phase 75 amp
   • Minimum Voltage Required=208V
   • 150 ft. x 6 gauge wire (0.000403) = 0.0605
   • 75 amps x 0.0605 = 4.53 volt drop
   • 220 volts (at source) –4.53 volts= 215.46 volts
   • Now, your heater will run properly.
2. Run a shorter cord. If by chance you could use a 50ft cord instead of a 150ft cord, then your formula would be as follows:
   • Example: P1800-1 phase 75 amp
   • Minimum Voltage Required=208V
   • 50ft. x 12 gauge wire (0.00162) = .08
   • 75 amps x .08= 6 volt drop
   • 220 volts (at source) –6 volts= 214 volts
   • Now, your heater will run properly
