THINGS YOU SHOULD KNOW
1.1 GAS APPLIANCE
Gas Safety (Installations and Use) Regulations.
In the interests of your safety and that of the
others it is a legal requirement that all gas
appliances are installed and correctly maintained
by a competent person and in accordance with
the latest regulations.
1.2 ELECTRICAL SUPPLY
Please ensure that this appliance has been
properly connected to the electrical supply by
means of a double pole isolator or un-switched
socket, and that the correct size of fuse (3 amp)
has been fitted.
Warning: this appliance must be earthed!
1.3 GUARANTEE REGISTRATION CARD
Please take the time to fill out your guarantee
registration card. The completed warranty card
should be posted within 30 days of installation.
GETTING STARTED
2.1 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;
●any external thermostats and their functions;
●the appliance controls.
2.2 APPLIANCE CONTROLS (fig. 1)
The appliance controls are concealed behind the
front flap. To gain access to the controls simply
pull the flap towards you in a downward motion.
The appliance is equipped with a simple keypad
that can be used to alter or display the following
functions:
●the outlet flow temperature to the central heating
system;
●switch on or off the boiler.
The pressure gauge shows the current pressure
of the 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.
Depending on the type of controls specified by
your installer you may have an integral Vokera
time clock fitted to the appliance, if so, instructions
can be found on page 6-7. If an external time
clock or programmer has been fitted, please refer
to the instructions supplied with such.
2.3 LIGHTING THE BOILER
Ensure the gas and electrical supply to the boiler
are turned on.
Whenthereisademandforheatingviathetimeclock
or programmer, the boiler will go through an ignition
sequence, whereby the burner will light.
If the appliance fails to ignite during the ignition
sequence, it will re-attempt ignition several times
before going to a lockout condition. Should this
occur, please allow a period of two minutes
before re-setting.
When the appliance reaches the set temperature,
the burner will go off for minimum period of
approximately 3 minutes.
When the programmer/time clock or external
thermostats heating request has been satisfied,
the appliance will switch off automatically.
2.4 ADJUSTING THE OPERATING PARAMETERS
(see fig. 1 & 1A)
Usually your installer will have adjusted the
operating parameters to suit your requirements,

parameters, please use the following procedure:
●press the MODE button repeatedly until you
see a fixed decimal point in LED 1;
●presstheSTEPbuttonrepeatedlyuntiltheparameter
that is to be adjusted is shown in LED 1;
●use the adjustment buttons (+/-) to alter the
current setting as shown in LED 2;
●press the STORE button to store the new
setting into the memory;
●press the MODE button repeatedly until no
decimal point is shown in LED 1.

HOW TO...
3.1 HOW TO TOP-UP THE SYSTEM PRESSURE (fig. 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).
●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.
3.2 HOW TO RESET THE APPLIANCE
