5. Operating Instructions
Once installed and commissioned by a qualified technician, operating your Immergas Victrix EXA 24 boiler is straightforward.
5.1. Initial Startup (by Technician)
The first startup involves purging air from the system, checking for leaks, verifying gas pressure, and adjusting combustion parameters. This procedure must be performed by a qualified technician.
5.2. Turning On/Off
- To Turn On: Ensure the gas supply is open and the electrical power is connected. Press the ON/OFF button on the control panel. The boiler will initiate its startup sequence.
- To Turn Off: Press the ON/OFF button. For extended periods of inactivity (e.g., summer), it is recommended to also close the gas supply valve and disconnect the electrical power.
5.3. Setting Temperature
Use the control panel to adjust the desired heating and domestic hot water temperatures. Refer to the specific controls on your boiler model for detailed instructions on temperature adjustment and mode selection (e.g., heating only, DHW only, heating + DHW).
5.4. System Pressure
Regularly check the system pressure gauge. The optimal operating pressure is typically between 1.0 and 1.5 bar when the system is cold. If the pressure drops significantly, consult the troubleshooting section or contact a technician.

7. Troubleshooting
This section provides solutions to common issues. For complex problems or if you are unsure, always contact a qualified service technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Boiler not firing / No heat | No gas supply, low system pressure, electrical fault, thermostat setting. | Check gas valve, check system pressure (repressurize if needed), check power supply, verify thermostat setting. If problem persists, contact technician. |
| Low system pressure | Leak in the system, expansion vessel fault. | Locate and fix leaks (if visible). Repressurize the system using the filling loop. If pressure drops frequently, contact technician. |
| Boiler making unusual noises | Air in the system, pump issue, limescale buildup. | Bleed radiators to remove air. If noise persists or is severe, contact technician. |
| No hot water | DHW setting incorrect, flow sensor fault, diverter valve issue. | Check DHW settings on control panel. If no change, contact technician. |
| Error code displayed | Specific fault detected by the boiler's internal diagnostics. | Refer to the boiler's specific error code list (usually found in the technician's manual or on the boiler itself). Attempt a reset if recommended. If error persists, contact technician. |
