User Manual for CLAS CH 0005, CH 0006, and CH 0007 Direct Gas Heaters

Quick guide from the manual

This document provides instructions for the CLAS CH 0005, CH 0006, and CH 0007 direct gas heaters. These devices are designed for industrial use only and require adequate ventilation. They must not be used in basements or enclosed spaces without proper air circulation. Always maintain a safety distance of 2 meters from walls and flammable objects.

Assembly

Follow these steps to assemble the heater:

1. Fix the foot to the base using the provided screws.
2. Attach the handle to the commutating box using the provided screws.

Gas connection

Ensure you use only Propane (G31) or Butane (G30) gas, or a mixture. The gas cylinder must be placed behind the device.

• Connect the pressure reducer (with safety valve) and the gas hose.
• Note that junctions are left-threaded; turn counter-clockwise to tighten.
• Check for leaks by applying soapy water to the connections; bubbles indicate a leak.
• Ensure the gas hose is fully extended and not obstructed.

Operation

Starting the heater:

1. Open the gas cylinder valve.
2. Turn on the fan using the white switch.
3. Press and hold the gas button while repeatedly pressing the piezoelectric lighter until the flame ignites.
4. Continue to hold the gas button for 15-20 seconds after ignition to activate the thermal safety devices.
5. Release the button; the flame should remain lit.

Stopping the heater:

1. Close the gas cylinder valve.
2. Allow the fan to run for a few seconds to cool the unit.
3. Turn off the fan using the white switch.

Maintenance

Before any maintenance, disconnect the power supply. The air outlet and nozzle are accessible by removing the control box cover (4 screws). Regularly clean the burner if used in dusty environments. Check electrode distances periodically.

Troubleshooting

If the motor does not start, check the power cable, fan, and switch. If the flame does not ignite, check the electrode distance, gas supply, and gas valve. If the flame extinguishes shortly after ignition, ensure the gas button was held long enough or check the safety chain. If the flame has a white luminous outline, clean the air inlet or adjust the pressure/nozzle.

Technical data

All models operate on 230V - 50Hz. The operating pressure is 1.5 Bar (21.75 Psi). Power output varies by model: CH 0005 (12kW), CH 0006 (15kW), CH 0007 (30kW).
