7.3 CLEANING THE BOILER
1. Remove any deposits from heat exchanger using a suitable soft brush. Do not use a brush with metallic bristles.
2. Check the condition of the combustion chamber insulation panels. Any damaged panels must be replaced. (Refer to
Component Replacement, Section 8.19).
3. Check the condition of the burner injector on the combustion chamber front assembly, carefully clean them with a soft
brush if necessary - Do not use a brush with metallic bristles as this might damage the injector.
4. Remove any deposits from the heat exchanger coils. This can be done by suction or water sprayed onto the coils.
Ensure all electrical components are protected from water. Any water used to clean the heat exchanger will drain to the
condensate trap.
5. Unscrew and replace the injector should it appear damaged.
6. Remove the four screws securing the burner (see Fig. 7.2) and remove the burner. Clean the burner with a soft brush
and check that the flame ports are clear. Blockages may be removed with a stiffer brush. Tap the burner, open end
down, to remove any deposits from inside.
7. Check the condition of the electrodes.
8. Check the spark gap, positioning and height of the electrodes, see Fig. 7.2.
9. Unscrew the condensate trap drain cap to remove any deposits.
Note:
Before removing the cap, ensure that the water released from the trap can be contained to avoid spillage.
The trap will contain no more than 200 cc of condensate water. Replace the drain cap.

7.4 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. Re-connect gas pipe union, reconnect the electrode leads and refit the air supply pipe.
4. Test the connections for gas tightness and re-commission, Sections 6.3 and 6.7.
5. Place the front case panel in position and secure in position with the four screws previously removed, see Fig. 7.2.
6. Raise the control panel and secure in position with the two screws provided.
7. Check the operation of the boiler. (Refer to Sections 6.4 and 6.5).
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.
