2.1 BEFORE SWITCHING ON
Before switching the appliance on, please familiarise yourself
with:
- howtoisolatetheappliancefromthegas,water,andelectricity
supplies;
- how to check and top-up – if necessary – the system water
pressure;
- the time clock or programmer (if tted);
- any external thermostats and their functions;
- the appliance controls.
2.2 APPLIANCE CONTROLS (see g. 1)
The appliance controls are situated on the lower front of the
appliance. The appliance controls include:
- pressure gauge;
- appliance mode selector;
- temperature selector;
- burner ON mode (green);
- fault indicator (red);
- servicing mode indicator (yellow)
NOTE
The appliance frost protection is active in all the boiler modes.
The temperature selector can be used to vary the temperature
of the water that circulates around your radiators.
The temperature range is adjustable between 40°C and 80°C.
When the status indicator (Green) is lit it indicates that the ame
is present and the burner is ON.
When the fault indicator (Red) is lit it indicates that the appliance
has identied a possible fault and performed a safety lockout.
When the fault indicator (Yellow) is lit it indicates that there is
a Servicing operation in progress.
2.3 LIGHTING THE BOILER
Ensure the gas and electrical supply to the boiler are
turned on.
Turn the mode selector switch to the ON position. When there
is a request for heating or hot water via the time clock or pro-
grammer, the boiler will begin an ignition sequence. When the
appliance reaches the CH set temperature, the burner will go
off for a minimum period of approximately 3 minutes.
When the programmer/time clock or external thermostats
heating request has been satised, the appliance will switch
off automatically.
2.4 ADJUSTING THE HEATING TEMPERATURE
Rotate the temperature selector – clockwise to increase, counter-
clockwisetodecrease–tothedesiredtemperaturesetting. The
temperaturecan be set from a minimum of 40°Ctoamaximum
of 80°C (if standard CH mode is selected).
2.5 EXPLANATION OF FEATURES
Although the Vokèra Vibe has been designed for simplicity of
use, it utilises the latest in boiler technology, enabling a host
of functions to be carried out simultaneously.
2.6 AUTOMATIC TEMPERATURE CONTROL
The automatic temperature control function (SARA), permits
the boiler (when the heating temperature selector is set within
4 and 6 sector) to automatically adjust (raise) the heating.
The activation and the disable of the function is visualized by
blinking the green led.
2. GETTING STARTED
3.1 HOW TO TOP-UPTHE SYSTEM PRESSURE
(g. 1-2)
Thesystempressuremustbecheckedperiodicallytoensurethe
correctoperation of the boiler.Theneedleonthe 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 lling valve connections (usually beneath the
boiler, see g. 2).
- Attach the lling loop to both connections.
- Open the lling valve slowly until you hear water entering the
system.
- Close the lling valve when the pressure gauge (on the boiler)
reads between 1 and 1.5 BAR (see g. 1).
- Remove the lling loop from the connections.
3.2 HOW TO RESET THE APPLIANCE
Whentheredfault LEDisilluminated, theappliancewillrequire
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 g. 1).

3.3 HOW TO SHUT DOWN THE SYSTEM FOR
SHORT PERIODS
The system and boiler can be shut down for short periods by
simply turning the time clock to the off position. It is also advis-
able to turn off the main water supply to the house.
3.4 HOW TO SHUT DOWN THE SYSTEM FOR
LONG PERIODS
If the house is to be left unoccupied for any length of time –
especially during the winter – the system should be thoroughly
drained of all water. The gas, water, and electricity supply to
the house should also be turned off. For more detailed advice
contact your installer.
3.5 HOW TO CARE FOR THE APPLIANCE
To clean the outer casing use only a clean damp cloth. Do not
use any scourers or abrasive cleaners.
