• If you are able to obtain hot water but not
heating it is also advisable to check the
clock connections and that the room
thermostat and time clock are calling for

• Remember that after hot water draw off
there is a 45 sec delay before the heating
will fire up if No.3 dipswitch is in the OFF
position, see fig 19 on page 27.
• When commissioning the boiler check the
inlet pressure is at 20mbar and burner
pressure against the Technical data on page
6.
• Note an anti-cycle delay time can be set up
to a maximum of 255 seconds by adjusting
potentiometer 2 as described in section 15.4
on page 27.
If you experience any problems please refer to

5.2 The boiler is designed to operate on fully
pumped, pressurised sealed systems operating at a
maximum of 3bar pressure and maximum design
flow temperature of 85
5.3 The boiler's integral expansion vessel is pre-
charged to a pressure of 0.5bar and will
accommodate a system volume of 125l at an
average water temperature of 75
system pressure of 3bar. If the system volume is
more than 125l an additional expansion vessel
must be fitted to suit the size of the system. A
