7. The boiler is designed to operate on a sealed system ie 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 INSTALLATION ROOM The appliance must be positioned in such a way as to be easily accessible at all times In addition the following minimum distances around the appliance must be complied with DISASSEMBLING INSTALLATION 11 Panel removal and access to hydraulic connections Ql p undo screws tilt panel towards you and lift clear remove the top cover loosen screws of the control panel turn up the control panel block the control panel with the screw INSTALLATION HEATING CONNECTION Limiting the maximum adjustable temperature Factory setting Hoor heating HEATING CONNECTION DHW Y PLAN Limiting the minimum adjustable temperature BO 85 C HEATING CONNECTION DHW S PLAN Limiting the minimum adjustable temperature BO 85 C
8. e f the boiler is not in regular daily use during cold periods it is recommended that it be fitted with a frost sensing thermostat to override the timeclock and prevent the system from freezing As with most boilers and heating appliances the casing and pipework can get hot during normal running so the boiler must not be covered and the surrounding area must be kept clear OPTIONAL INTERNAL TIMECLOCK e his operates on a 24 hour sequence Around the outside of the clock there are a number of white tabs these allow 15 minute switching times To set a boiler cycle simply push outwards the number of tabs required for your heating period Remember tab OUT BOILER ON tab IN BOILER OFF The time of day is marked by an arrow on the inner part of the clock set the outer time to coincide with this arrow On the centre part of the clock there is a switch This has three positions e Switch down timeclock off e Switch middle timeclock timed normal position e Switch up timeclock on constant PRESSURE IN THE HEATING SYSTEM The CH pressure must be a minimum of 1 bar and must be checked by the end user on a regular basis If the pressure drops under O 5 bar the integrated water pressure switch blocks the appliance until the pressure in the system returns to a level above O 8 bar The installer fits the system with a separate fill valve underneath the appliance Make sure that the appliance is powered off when filling
