32 Alpha HE CB25/33, SY25 - Component Replacement
8.30 EXPANSION VESSEL
Note: If there is less than 450 mm clearance above the boiler or a rear exit flue is used, it is not possible to replace the vessel,
in which case an additional vessel should be fitted external to the boiler in the central heating return pipe, as close to the boiler
as possible (see Fig. 5).
1. Gain access behind the casing and drain the boiler heating circuit as described in Sections 8.1 and 8.2.
2. Disconnect the pipe from the pump inlet manifold and expansion vessel.
3. Remove the four screws securing the top support plate.
4. Lift the expansion vessel out of the boiler.
5. When replacing the vessel, ensure that the connection is towards the front of the boiler and re-assemble in reverse order
using new seals as necessary.
6. Refill and pressurise the system. (Refer to Commissioning, Section 5.1).
8.31 CONDENSATE TRAP - Fig. 11
1. Gain access behind the casing and drain the trap as described in Sections 8.1 and 8.2.
2. Remove the screw securing the trap to its support bracket.
3. Remove the clip from the tube at the top of the trap.
4. Disconnect the outlet drain connection.
5. Lift the trap out and re-assemble with a new condensate trap.
