RE-ASSEMBLE THE BOILER

1. 

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 and secure with the four 10 mm nuts 

previously removed. Replace seals if necessary.

3.  Ensure the injector is in position in the gas valve outlet and re-connect the gas pipe securing it in position with the 

spring clips previously removed.

4.  Reconnect the fan wiring plug and air pressure tube.
5.  Insert the air inlet pipe into the fan and re-fit the screw securing top of the pipe.
6.  Re-fit the ignition lead to the electrode.
7.  Check all the connections are sound and re-commission, Sections 6.3 and 6.8.
8.  Raise the control panel and clip into place.
9.  Check that the insulation on the back of the case front panel is intact and in position (it also acts as a case seal), then 

place the panel in position over the top pins and secure with the two screws previously removed.

10.  Refit the control panel cover and secure in position with the two screws and cover plugs.
11.  Check the operation of the boiler. (Refer to Sections 6.5 and 6.6).
12.  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.
