Earth the boiler correctly for safety. Before energizing, double-check all connections and wiring. A qualified electrician should verify the electrical installation before operation.

Operating Instructions

The Alpha Evoke 28 is user-friendly, offering simple controls for central heating and domestic hot water. Follow these instructions for optimal performance and safety.

Initial Start-Up and System Filling

Before initial start-up, ensure the boiler is correctly installed and all gas and electrical connections are verified by a qualified engineer. Begin by opening the filling loop valve to introduce water into the system. Monitor the pressure gauge; the ideal operating pressure is typically between 1 and 1.5 bar.

As the system fills, bleed any air from the radiators using radiator bleed keys, starting with those closest to the boiler. Close the filling loop valve once the correct pressure is achieved. Power on the boiler and follow the on-screen prompts. The boiler will perform a self-diagnostic check. If any error codes appear, consult the troubleshooting section of this manual. Allow the system to fully heat up before adjusting temperature settings.

Setting the Central Heating Temperature

The Alpha Evoke 28 allows precise control over your central heating temperature. Access the temperature settings via the boiler’s control panel – typically using the up and down arrow buttons. The current setpoint will be displayed on the screen. You can adjust the temperature in increments of 0.5°C or 1°C, depending on the model’s settings.

Consider setting a schedule to optimize energy efficiency. Lower temperatures during periods of inactivity, such as overnight or when the house is empty. Many models offer pre-programmed modes or allow for custom schedules. Remember that lower temperatures save energy, but ensure comfort levels are maintained. Regularly review and adjust settings as needed.

Adjusting Domestic Hot Water Temperature

The Alpha Evoke 28 enables you to customize your domestic hot water temperature. Use the control panel to navigate to the hot water settings – often indicated by a tap or shower icon. Adjust the temperature using the arrow buttons, typically within a range of 40°C to 60°C. A comfortable and safe temperature is generally between 50°C and 55°C.

Be cautious of setting excessively high temperatures, as this can increase the risk of scalding. Lower temperatures conserve energy, but ensure sufficient heat for your needs. Some models feature ‘comfort’ modes for faster heating or ‘eco’ modes for energy savings. Regularly check and adjust the temperature to maintain optimal performance.

Troubleshooting Common Issues

This section details solutions for typical problems, including ignition failures, low pressure, and error codes, helping you resolve issues with your Alpha Evoke 28.

Boiler Not Igniting

If your Alpha Evoke 28 boiler fails to ignite, several factors could be responsible; First, verify the gas supply is active and the boiler is receiving gas. Check that the electrical connection is secure and the boiler has power.

Ensure the system is properly vented and there are no airlocks in the system. A low gas pressure or a faulty ignition component can also prevent ignition. If the issue persists, reset the boiler by turning it off and on again.

Consult the error code display for specific diagnostics. If these steps don’t resolve the problem, contact a qualified gas engineer for assistance, as attempting repairs yourself could be dangerous and void the warranty.

Low Pressure Problems

Experiencing low pressure on your Alpha Evoke 28 boiler often indicates a water leak within the central heating system. Carefully inspect all visible pipes, radiators, and the boiler itself for any signs of dampness or dripping water.

A gradual pressure loss usually points to a slow leak, while a sudden drop suggests a more significant issue. To temporarily resolve low pressure, you can repressurize the system using the filling loop, following the instructions in the ‘Initial Start-Up’ section.

However, repressurizing is a temporary fix; identifying and repairing the leak is crucial. If you cannot locate the leak or the pressure continues to drop, contact a qualified heating engineer for professional assistance.

Error Codes and Their Meanings

The Alpha Evoke 28 boiler utilizes error codes to diagnose potential issues. These codes are displayed on the boiler’s control panel, providing valuable information for troubleshooting. A flashing code indicates a fault requiring attention.

Common codes include: codes relating to flame detection issues, gas supply problems, or pump failures. Refer to the complete error code list in the full installation and servicing instructions (available as a PDF download).

Attempting to reset the boiler after noting the code may resolve minor faults, but persistent codes necessitate professional assistance. Do not attempt repairs yourself; always contact a qualified heating engineer for diagnosis and repair.

Maintenance and Servicing

Regular maintenance ensures optimal performance and longevity of your Alpha Evoke 28 boiler. Annual servicing by a qualified engineer is crucial for safety.

Regular Maintenance Tasks

To maintain your Alpha Evoke 28 boiler’s efficiency and reliability, several routine checks can be performed by the user. Regularly visually inspect the boiler for any leaks or signs of corrosion. Ensure the boiler casing is kept clean and free from obstructions to allow for proper ventilation.

Check the system pressure monthly, ensuring it remains within the manufacturer’s recommended range – typically between 1 and 1.5 bar. If pressure is low, follow the instructions in the ‘Initial Start-Up’ section to repressurise.

Periodically check the flue terminal is unobstructed by debris or snow. Do not attempt any internal repairs or servicing yourself; always consult a qualified Gas Safe registered engineer for these tasks.

Annual Servicing Requirements

An annual service by a qualified Gas Safe registered engineer is crucial for the safe and efficient operation of your Alpha Evoke 28 boiler.
