Preliminary checks

Remove the front panel of the boiler and per-
form the following checks before switching
the boiler on or testing any of its functions.
- Check that the fuel and water circuit shut-off
cocks are open
- Check that the type and pressure of the gas
supply are as specified for the boiler
- Check that the water circuit pressure gauge
shows a pressure over 1 bar with the system
cold. Check also that the central heating
circuit is properly de-aerated.
- Check that the pressure in the central hea-
ting circuit expansion vessel is sufficient
(about 1 bar).
- Check that the electrical connections to the
mains supply and to the system's control
