control, room thermostats etc. to the customers specific
requirements.
9. The 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 boiler
thermostat is in the OFF position and it is necessary

electrical and gas supplies to be isolated.
It is recommended that a label be affixed to the
appliance to draw attention to the fact that the system
has been drained.

and the boiler lit, the action of the frost protection
thermostat will prevent the boiler from shutting down
