4. Bedienungsanleitung
This heater features manual controls for ignition and heat output. No electrical power is required for basic operation.
4.1 Lighting the Heater (Piezo Ignition)
- Stellen Sie sicher, dass das Gaszufuhrventil geöffnet ist.
- Locate the control knob and the ignitor button on the heater.
- Push in and turn the control knob counter-clockwise to the 'PILOT IGN' position.
- While holding the control knob in, repeatedly press the ignitor button until the pilot flame ignites. You should see a small blue flame at the pilot burner.
- Continue to hold the control knob in for approximately 30-60 seconds after the pilot flame ignites. This allows the thermocouple to heat up and hold the pilot valve open.
- Release the control knob. If the pilot flame extinguishes, repeat steps 3-5.
- Once the pilot flame is stable, push in and turn the control knob counter-clockwise to your desired heat setting (LOW, MEDIUM, or HIGH). The main burner will ignite.
