What should I do if it shows an error (e.g., Error 4)?

Common causes:

• Temperature sensor issue
• Low gas pressure or supply
• Ventilation problem (gas units)
• Overheating protection activated

👉 Error codes are safety indicators, not random faults.

What to do:

1. Turn off the unit
2. Wait a few seconds
3. Restart

If the error persists → contact authorized service.
