4. Operating Instructions
Once installed and commissioned by a qualified technician, your Immergas boiler is ready for operation.
4.1 Powering On/Off
- To Power On: Ensure the gas supply is open and the electrical supply to the boiler is switched on. The boiler will typically perform a self-check.

4.2 Temperature Adjustment
Use the control panel on the boiler to adjust the central heating and domestic hot water temperatures. Refer to the specific icons and buttons on your boiler's interface for precise adjustments. Typically, 'CH' or a radiator icon controls heating, and a tap icon controls hot water.
