IMPORTANT
1If after completing the start-up procedure correctly, the burner fail to ignite and the boiler shut
down warning lights up, wait about 15 seconds then press the reset switch.
The reset electronic control unit will repeat the start-up cycle.
2If there is a power failure while the boiler is in operation, the burners automatically go out and re-
ignite when the power returns.
3The boiler is protected by an integral frost-stat, but if the boiler is not to be used for a long period
of time, the system should be drained.
Note: The frost thermostat operates even if the C.H. temperature setting knob is in the OFF position
and it is necessary therefore, if the system is drained, for the external electrical and gas
supplies to be isolated.
4To ensure trouble free, efficient and safe operation of the appliance we advise that an annual check
and maintenance contract be arranged with a reputable and competent service company.
