This manual provides essential instructions for the safe operation and maintenance of the WilTec 15kW gas heater (model 65023). Always read the full safety warnings before use. This device is intended for use in well-ventilated areas and is not suitable for domestic use, caravans, or heating living spaces.
Safety Instructions
- Burn Hazard: Do not touch hot surfaces. Keep children and animals away.
- Ventilation: Continuous ventilation is required (25 cm³ per kW).
- Gas Leaks: If you smell gas, immediately close the gas supply, extinguish all flames, and ventilate the area. Do not use electrical switches or phones in the area.
- Placement: Do not use in basements or below-ground rooms. Keep the heater at least 3 meters away from flammable walls or ceilings.
- Gas Bottles: Secure gas bottles to prevent falling. Do not direct hot air toward the gas bottle.
Installation
Ensure the heater is connected to a grounded 230 V ~ 50 Hz power supply. Connect the gas hose to the pressure regulator and the LPG bottle. Tighten connections firmly. Always check for leaks using a soapy water solution; never use an open flame to detect leaks.
Operating Instructions
Ignition
- Set the power switch to "I" and verify the fan is running.
- Press the gas valve button and repeatedly press the piezo igniter until the flame lights.
- Hold the gas valve button for approximately 10 seconds after ignition. If the flame goes out, wait 1 minute and repeat.
- Adjust the heat output using the pressure regulator wheel.
Shutdown
Close the gas bottle valve first. Allow the fan to run until the flame extinguishes, then turn the power switch to "O".
Maintenance
- Repairs must be performed by specialists.
- Have the unit checked by a technician at least once a year.
- Periodically inspect the gas hose and pressure regulator.
- Clean the fan blades and the interior of the heater with compressed air if necessary.
- Check the position of the ignition electrode.
Troubleshooting
If the motor does not run, check the power supply and the safety thermostat. If the burner fails to ignite, check the gas supply, nozzle, and ignition electrode. If the heater stops during operation, check for ice formation on the gas bottle (use a larger bottle or two connected bottles) and ensure proper airflow.
