System draining

If at any time after installation it is necessary to drain and refill the central
heating system (e.g. when replacing a radiator) the De-Aeration function
must be activated to avoid air being trapped in the system.
See
De-Aeration function, page 48.
Once De-Aeration is complete recommission the boiler and check that the
inhibitor concentration is sufficient.
