Control Panel
A single phase 230V supply is required for the
control panel operation. Single phase burners
are electrically supplied via the control
panel. Three phase burners require a
separate three phase isolated supply (by the installer
to allow for boiler/burner door opening. A separate
run between the control panel and the burner. All
power supplies to the boiler/burner/other associated
equipment (ie: gas booster, separate oil pump, etc.)
should be isolated via the same switched isolator.
