3.1 HOW TO TOP-UP THE SYSTEM PRESSURE

(

g. 1-2)

The system pressure must be checked periodically to ensure the
correct operation of the boiler. The needle on the gauge should
be reading between 1 and 1.5 BAR when the boiler is in an off
position and has cooled to room temperature. If the pressure
requires ‘topping-up’ use the following instructions as a guide.
- Locate the fi lling valve connections (usually beneath the

boiler, see fi g. 2).

- Attach the fi lling loop to both connections.
- Open the fi lling valve slowly until you hear water entering the

system.

- Close the fi lling valve when the pressure gauge (on the boiler)

reads between 1 and 1.5 BAR (see fi g. 1).

- Remove the fi lling loop from the connections.

3.2 HOW TO RESET THE APPLIANCE

When the red fault LED is illuminated, the appliance will require
to be reset manually. Before resetting the boiler, check what
action is required to be taken, using the information on the
fault code table below. Allow a period of two minutes to elapse
before rotate the mode selector knob across the

position

(see fi g. 1).

IMPORTANT
