Operate the system, following the
operating instructions supplied with
the boiler.

●

Check the system for water leaks
and escaping gas.

●

Check that the flue has been
correctly installed, according to the
fitting instructions supplied with the
flue assembly.

●

Check the burner for correct
ignition and flame picture.

●

Check the hot water system for
correct operation.

●

Check the heating system for
correct operation.
