6.4 RE-ASSEMBLE THE BOILER

1. Replace the burner, ensuring it is located correctly and secure it in position using the four screws previously removed.

Important: Before replacing the combustion chamber front assembly, pour at least 200 cc of water into the coils of the

heat exchanger. This is to ensure the condensate trap is full of water before operating the boiler.

2. Replace the combustion chamber front assembly, ensuring it is correctly located.

3. Ensure the electrode lead is connected and the seal is in position in the bottom of the room sealed chamber.

4. Test the connections for gas tightness and re-commission, Sections 5.3 and 5.7.

5. Place the front case panel in position and secure in position with the four screws previously removed, see Fig. 30.

6. Raise the control panel and secure in position with the two screws provided.

7. Check the operation of the boiler. (Refer to Sections 5.4 and 5.5).

8. Return all controls to their original settings.

To ensure correct and safe operation of the appliance, it is essential that any worn or failed components are replaced with

only genuine Alpha spare parts. Use of non-genuine Alpha spares could invalidate your warranty and may pose a potential

safety hazard.
