The system must be filled up slowly the first time; once it is
filled and the air expelled it should never need to be topped
up again.

Systems should also be operated at maximum working
temperature the first time they are started up, in order to
facilitate de-aeration. (Gas is not released from the water at
low temperatures).

An automatic spurge can be performed during the first igni-
tion. The parameter that set the cycle is Par. 139. See param-
eter table for more information.
