4.1

Preliminary checks

It is essential to perform the following checks
before starting up or testing the functioning of
the boiler. In particular:
- Check that the water and fuel shut-off cocks
are open.
- Check that the type and pressure of the gas
supply are as specified for the boiler.
- Check that the central heating circuit pres-
sure gauge shows a pressure of 1.5 bar with
the system cold. Check also that the circuit
is properly de-aerated.
- Check that all electrical connections to the
mains supply and to the system's control
and safety devices have been made cor-
rectly.
- Check that the flue is properly constructed.
