FROST PROTECTION
the boiler is NOT fitted with frost protection. If the boiler is being installed in a position where freezing
could take place, then a suitable external frost thermostat should be fitted.
CONNECTING TO THE SYSTEM
the boiler is designed to operate on a sealed system (ie. no open vent or feed and expansion cistern)
Hot water expansion within the system is taken up by the internal 10 litre expansion vessel. This is
suitable for systems up to 160 litres capacity. If the system capacity is more than this then an additional
expansion vessel may be required.This can be fitted external to the boiler at a convenient place on the
pipework.
Please note that the circulation pump is fitted to the flow connection.
