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.
1.4 APPLIANCE LOG BOOK
A log book is supplied with the boiler. This
important document must be completed during
the installation/commissioning of your boiler.
Failure to install and commission the appliance in
accordance with the manufacturers instructions
may invalidate the warranty. This does not affect
your statutory rights.
1.5 HOW DOES IT WORK?
Your Eclipse ESC is a combination boiler, which
supplies heated water to your radiators and hot
water to your taps. The central heating is controlled
via a time clock and/or any thermostats that your
installer may have fitted. The boiler will light when
a hot water outlet (a tap) is opened. The boiler
also functions periodically to pre-heat the hot
water heat exchanger. The Eclipse boiler lights
electronically and does not have a pilot light. In
the unlikely event of a fault developing with your
boiler, the supply of gas to the burner will be
terminated automatically.

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;
●the outlet temperature for domestic hot water;
●the allowable drop in temperature before the boiler
pre-heats the domestic hot water heat exchanger;
●switch on or off the central heating.
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. The boiler will now go through a
self-test and purge sequence. On completion of
the self-test and purge sequence, the boiler will
pre-heat the DHW heat exchanger if it is below
55°C, however should a hot water outlet be
opened the boiler will operate in the domestic hot
water mode to supply hot water to the tap.

4
When there is a demand for heating via the
timeclock, 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,
however should you wish to alter the operating
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.
To change the hot water outlet temperature
(variable between 40 - 65°C) press STEP button
until LED 1 shows 1.
Use the adjustment buttons (=/-) to alter the current
value to the new value.
Press the STORE button to save the new value.
Press the MODE button until no decimal point is shown
in LED 1.
To change the pre-heat temperature drop (02 =
5°C, 03 = 10°C, 04 = 20°C, 05 = 30°C) press the STEP
button until LED 1 shows 2.
Use the adjustment buttons (=/-) to alter the current
value to the new value.
Press the STORE button to save the new value.
Press the MODE button until no decimal point is shown
in LED 1.
To switch the central heating ON or OFF (00 = OFF, 01
= ON) press the STEP button until LED 1 shows 3.
Use the adjustment buttons (=/-) to alter the current
value to the new value.
Press the STORE button to save the new value.
Press the MODE button until no decimal point is shown
in LED 1.
To change the central heating flow temperature
(variable between 20°C and 90°C) press the STEP
button until LED 1 shows 4.
Use the adjustment buttons (=/-) to alter the current
value to the new value.
Press the STORE button to save the new value.
Press the MODE button 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
When the status light is illuminated red, the
appliance will require to be reset manually. Before
resetting the boiler ensure that the pressure
gauge is indicating the correct level. Allow a
period of two minutes to elapse before pressing
the reset button.
IMPORTANT
If the appliance requires to be reset frequently, it may
be indicative of a fault, please contact your installer or
Vokera Customer Services for further advice.
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 advisable 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.
Fig. 2
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.
3.6 HOW TO REGULATE THE HOT WATER
TEMPERATURE
Usually your installer will have adjusted the hot
water output to suit your requirements, however
if you would like to adjust the outlet temperature,
please follow the instructions in section 2.4.
NOTE
If you find that the hot water temperature is still
insufficient, try reducing the flow of water through
the tap.
