Before switching onBefore switching on

Before switching on

Before switching the appliance on please familiarise yourself with:

● how to isolate the appliance from the gas, water, and

electricity supplies;

● how to check and top-up – if necessary – the system

water pressure;

● the time clock or programmer;

● any external thermostats and their functions;

● the appliance controls.

2.22.2

Appliance controls (see fig. 1)Appliance controls (see fig. 1)

Appliance controls (see fig. 1)

The appliance controls are situated on the lower front of the appliance. The appliance controls include:

● pressure gauge;

● appliance mode selector;

● temperature selector;

● 2-digit LED display;

● burner ON mode (green);

● fault indicator (red);

● optional - integral time clock/programmer (if fitted).

The

pressure gauge

shows the current pressure of your heating system, the gauge should be set between 1 and 1.5 BAR. When the appliance is operating the gauge may rise or fall slightly, this is quite normal. The minimum permissible level for the safe and efficient operation of the appliance is

0.5 BAR. Should the pressure fall below 0.5 BAR, the boiler may lockout.

The appliance mode selector is used to switch the boiler to the various operating modes:

● OFF/RESET “ ”

● DHW MODE ” ”

● CH MODE “ ”

● CH with PREHEATING MODE “ ”

NONO

E The appliance frost protection is active in all of the above modes.

The

temperature selectorstemperature selectors

temperature selectors can be used to vary the temperature of the water that circulates around your radiators and the water that flows from your hot water taps. The temperature range is adjustable between 40

and 80

C for the central heating, and between 35oC and

C for the hot water. Moreover if floor heating mode is selected (by using the relative jumper), the temperature range for CH mode can be modified between 20°C and 45°C.

2 & 3)2 & 3)

2 & 3)

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 filling valve connections (usually beneath the

boiler, see fig. 2).

● Attach the filling loop to both connections.

● Open the filling valve slowly until you hear water entering

the system.

● Close the filling valve when the pressure gauge (on the

boiler) reads between 1 and 1.5 BAR.

● Remove the filling loop from the connections.
