[FONT=Swis721BT,Bold]51 EXPANSION VESSEL REPLACEMENT[/FONT]
If the CH expansion vessel is faulty, there are 2 options:
A If it has a punctured diaphragm, but is otherwise leak free,
than it can be left in place and a new vessel added to the
return side of the system, external to the boiler, provided it
is of adequate capacity and pre---charge pressure.
B If there is at least 400 mm (16”) clearance above the
boiler, the expansion vessel can be changed without
removing the boiler (rear exit flues will have to be
disturbed).
For option B, proceed as follows:
1 Disconnect the electrical supply.
2 Gain access to the controls area by removing the boiler
front panel (refer to frame 36).
3 Close off the isolating cocks of the CH circuit at the
bottom of the boiler.
4 Release system pressure by opening the main circuit
drainage cock.
