1.1 GAS APPLIANCES
1.3 WARRANTY REGISTRATION
Please take the time to register the appliance warranty using
the documentation provided, call 0800 479 0754 (UK) or 056
7755055 to obtain your warranty confirmation code (please
have your appliance warranty card to hand).

1.4 APPLIANCE COMMISSIONING CHECKLIST
(UK only)
The Benchmark checklist section can be found at the rear of
the appliance installation booklet. This important document
must be completed during the installation/commissioning of
your boiler. All GAS SAFE registered installers carry a GAS
SAFE ID card, and have a registration number. These details
should be recorded in the Benchmark commissioning checklist
section within the installation booklet. You can check your
installers details by calling GAS SAFE direct on 08004085500.
Failure to install and commission the appliance in accordance
with the manufacturers instructions will invalidate the warranty.
This does not affect your statutory rights.
Your evolve boiler supplies heated water to your radiators
and hot water to your hot water taps. The central heating is
controlled via a time clock and any thermostats that your installer
may have fitted. The boiler will light when it receives a request
from the time clock via any thermostat that may be installed, or
whenever a hot water outlet (tap) is opened. Your evolve 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.

1.5 HOW DOES IT WORK?
1.8 FROST PROTECTION SYSTEM
The evolve is equipped with a built-in frost protection system,
this enables the boiler to over-ride the time controls – even if
switched off – and operate the burner and/or pump, should
the temperature within the appliance drop below 5 °C. Please
note that the frost protection system is designed to protect the
appliance only, should frost protection be required for the heating
system, additional controls may be required.
NOTE
The frost protection system is reliant on the appliance having a
permanent electrical supply, and being in a non-fault condition.
1.9 APPLIANCE STATUS INDICATORS
Your appliance incorporates the REC 10 UI (User Interface),
that displays information on appliance status and condition.
3
CONTROL PANEL (REC10)
Depending on the type of application, some of the functions described in this manual might not be available.
LED
The REC 10 UI is a multi-functional control that
enables you to view the operating status of your
appliance at a glance; and is also used to adjust/set
the various ‘User’ settings, including temperature setpoints.
The REC 10 UI also incorporates an embedded timer
that - if enabled - can be used to program and control
the ON/OFF times for your central heating. Please
consult you installer for further advice on this function.
The REC 10 UI features a backlit liquid crystal display.

System Icons may appear on both the left and right of the display; and they signify the following condition/status:
This icon indicates that the OFF operating status mode has been set. Each ignition request is ignored except for the frost-protection
function. The pump anti-lock, 3-way valve and frost-protection function remain active.
This icon indicates that WINTER mode has been selected (HEATING function enabled). If a heating request from the main zone is in
progress, the icon will be flashing.
This icon indicates that the circuit for domestic hot water production is enabled. When a domestic hot water request is in progress, the
icon flashes. The “P” at the top of the domestic hot water icon indicates that the boiler preheating function is enabled; the “P” when
flashing indicates that a preheating request is in progress.
When the “central heating programming timing” is enabled this icon indicates that the system heating (main zone) is in AUTOMATIC
mode (the management of the heating requests follows what has been set with the timer).
If the heating function is not enabled during the current time frame, the icon will be crossed out.
When the “central heating programming timing” is enabled this icon indicates that the system heating (main zone) is in MANUAL mode
(the management of the heating requests does not follow what has been set with the programming timing, but it is always active).
OFF
This icon indicates that the system (main zone) has been set to off (not active).
This icon indicates that the system is detecting the presence of a flame.
This icon indicates the presence of an anomaly or fault condition, and is always flashing.
Note:
The temperature of the hot water sensor is shown at the centre of the main screen. The value’s meaning is indicated at the bottom of the display.
Whenever a heating request is in progress, the value displayed at the centre of the screen refers to the system’s flow sensor, with the relative
indication.
The value expressed in bar refers to the system’s water pressure.
The top of the screen shows the current date and time, as well as the outdoor temperature, if available.

3. HOW TO...
3.1 HOW TO TOP-UP THE SYSTEM PRESSURE
The system pressure must be checked periodically to ensure
the correct operation of the boiler. The system pressure is
shown at the top of the LCD display or can be read on the
gauge located on the underside of the appliance. When the
boiler is at room temperature, the system pressure should be
approximately 1.0 bar.
If the pressure requires ‘topping-up’ use the following instructions
as a guide.
- Locate the filling valve connections (usually beneath the
boiler, see fig. 1).
- 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
Reset function
In order to reset the boiler’s operation in the event of a fault,
it is necessary to access the fault description screen. If the
lockout is of a non-volatile type that requires a reset procedure,
this will be indicated on the screen, and can be carried out by
pressing the “ok” button on the REC10.
E020
LIMTIT THERMOSTAT
PRESS OK RESET
At this point, if the correct operating conditions have been
restored, the boiler will restart automatically.
If the attempts to reset the fault do not restore the boiler’s
functionality, please contact your local Customer Support
Service.
Up to a maximum of 3 reset attempts can be made using the
REC10, after which the machine must be disconnected from
the power supply to reset the number of attempts available.
bbRequest the intervention of the Technical Assistance
Centre.
3.3 HOW TO SHUT DOWN THE SYSTEM FOR
SHORT PERIODS
If necessary the boiler status can be switched to the OFF
position during short periods of absence.
BOILER
OFF
SUMMER
WINTER
Provided that the electrical and gas supplies remain switched
ON to the appliance, the following frost-protection functions
will remain active in order to protect the appliance:
- heating frost-protection: this function is activated if the
temperature measured by the flow sensor drops below 5°C.
A heat request is generated in this phase with the ignition of
the burner at minimum output, which is maintained until the
outlet water temperature reaches 35° C;
- DHW frost-protection: the function starts if the temperature
measured by the DHW sensor falls below 5°C. A heat request
is generated in this phase with the ignition of the burner at
minimum output, which is maintained until the outlet water
temperature reaches 55° C.
bbThe activation of the FROST-PROTECTION function
is indicated by a scrolling message at the base of the
REC10 display.
- pump anti-blocking: the circulating pump is energised
for a 30-second period if it remains inactive for more than
24-hours.
3.4 HOW TO SHUT DOWN THE SYSTEM FOR
LONG PERIODS
If the boiler will not be in used for a prolonged period of time,
the following operations must be carried out:
-- switch the boiler to OFF
-- isolate the appliance from the gas and electricity supplies.
In this case, the frost-protection and anti-blocking systems
are deactivated. Drain both the heating and domestic water
systems to avoid any risk of freezing.

INSTALLATION AND SERVICING INSTRUCTIONS
INTRODUCTION
All installers are asked to follow the Benchmark Scheme by
adhering to the Code of Practise, which can be obtained from
www.centralheating.co.uk.
The evolve has a new ACC (Active Combustion Control) system.
This new control system ensures functionality, efficiency and
low emissions under any conditions.
The ACC system uses an ionisation sensor immersed in the
burner flame, whose information allows the control board to
operate the gas valve that regulates the fuel.
This sophisticated control system provides the auto-regulation
of the combustion, so there is no need for an initial calibration.
The ACC system is able to adapt the boiler to operate with
different gas compositions, different outlet pipes lengths and
different altitudes (within the specified design limits).
The ACC system can also perform an auto-diagnostic operation
that locks out the burner before the permitted upper emission
limit is exceeded.
The comprises a range of high-efficiency combination boilers.
These appliances – by design – incorporate electronic ignition,
circulating pump, expansion vessel, safety valve, pressure
gauge and automatic by-pass.
The range is produced as room sealed, category II2H3P
appliances, suitable for internal wall mounting applications only.
Each appliance is provided with a fan powered flue outlet with
an annular co-axial combustion air intake that can be rotated
– horizontally – through 360 degrees for various horizontal or
vertical applications.
These appliances are designed for use with a sealed system
only; consequently they are not intended for use on open
vented systems.
This booklet is an integral part of the appliance. It is therefore
necessary to ensure that the booklet is handed to the person
responsible for the property in which the appliance is located/
installed. A replacement copy can be obtained online from the
Vokera website.
When the product reaches the end of its life it should dismantled
and recycled in accordance with current requirements. Local
authority waste collection facilities may offer such disposal
services.
The boiler complies with basic requirements of the following
Directives:
Gas directive 2009/142/EC;
Yield directive: Article 7(2) and Annex III of directive 92/42/EEC;
Electromagnetic compatibility directive 2014/30/EU;
Low-voltage directive 2014/35/EU;
Directive 2009/125/EC Ecodesign for energy-using appliances;
Directive 2010/30/EU Indication by labelling of the consumption
of energy by energy-related products;

SECTION 1 - DESIGN PRINCIPLES AND OPERATING SEQUENCE
1.1 PRINCIPLE COMPONENTS
• A fully integrated electronic control board featuring electronic
temperature control, anti-cycle control, pump over-run, selfdiagnostic fault indicator, full air/gas modulation
• Aluminium heat exchanger
• Electronic ignition with flame supervision
• Integral high-head pump
• Fan
• Expansion vessel
• Water flowmeter
• Flue sensor
• Pressure transducer
• Safety valve
1.2 MODE OF OPERATION (at rest)
When the appliance is at rest and there are no requests for
heating or hot water, the following functions are active:
• frost-protection system: the frost-protection system protects
the appliance against the risk of frost damage both for CH
and DHW. For CH line, if the main temperature falls to 5°C,
the appliance will function on minimum power until the
temperature on main reaches 35°C.
Moreover if the DHW temperature falls to 5°C, the appliance
will function on minimum power until the temperature on main
reaches 55°C.
• anti-block function: the anti-block function enables the pump
and divertor valve actuator to be energised for short periods,
when the appliance has been inactive for more than 24-hours.
1.5 SAFETY DEVICES
When the appliance is in use, safe operation is ensured by:
• a pressure transducer that monitors system water pressure
and will de-activate the pump, fan, and burner should the
system water pressure drop below the required minimum
value;
• fan speed sensor to ensure safe operation of the burner;
• a high limit thermostat that over-rides the temperature control
circuit to prevent or interrupt the operation of the burner;
• flame sensor that will shut down the burner when no flame
signal is detected and/or when incomplete combustion or
high emissions are detected;
• flue sensor that will shut down the burner if the flue threshold
temperature is exceeded;
• a safety valve which releases excess pressure from the
primary circuit.
NOTE
When the appliance is first switched ON or when the electrical
supply is interrupted then restored, the appliance will enter a
short ‘purge’ cycle whereby the pump cycles ON & OFF for
approximately 2-minutes. Only when the ‘purge’ cycle has been
completed, will the appliance go through an ignition sequence.
Flow temperature
sensor
Upper AAV
Main heat
exchanger
1.3 MODE OF OPERATION (Heating)
When there is a request for heat via the REC/or any external
control, the pump and fan are started, the fan speed will modulate
until the correct signal voltage is received at the control PCB.
At this point an ignition sequence is enabled.
Ignition is sensed by the electronic circuit to ensure flame stability
at the burner. Once successful ignition has been achieved, the
electronic circuitry increases the gas rate to 75% for a period of
15 minutes. Thereafter, the boiler’s output will either be increase
to maximum or modulate to suit the set requirement. When
the appliance reaches the desired temperature the burner will
shut down and the boiler will perform a three-minute anti-cycle
(timer delay).
When the request for heat has been satisfied the appliance
pump and fan may continue to operate to dissipate any residual
heat within the appliance.
1.4 MODE OF OPERATION (Hot water)
When there is a request for DHW via a hot water outlet or tap,
the pump and fan are started, the fan speed will modulate until
the correct signal voltage is received at the control PCB. At this
point an ignition sequence is enabled.
Ignition is sensed by the electronic circuit to ensure flame
stability at the burner. Once successful ignition has been
achieved, the electronic circuitry increases the gas rate to
maximum or will modulate output to stabilise the temperature.
In the event of the appliance exceeding the desired temperature
(set point) the burner will shut down until the temperature drops.
When the request for DHW has been satisfied the appliance
pump and fan may continue to operate to dissipate any residual
heat within the appliance.

SECTION 3 - CONTROL PANEL (REC10)
LED
The REC10 is a fully functional UI (User Interface)
that acts as a visual reference for the appliance and
system status; and can also be used to view, input
and adjust relevant system parameters and functions.
The centre of the UI will normally display the current
operating temperature (according to the mode of
operation); however when the screensaver is active,
the current time will be displayed.
The value expressed in bar refers to the system’s
water pressure.
The top of the screen shows the information regarding
the current date and time, as well as the outdoor
temperature, if available.
On the left and right sides are displayed the icons
indicating the status of the system; their meaning is
as follows.

This icon indicates that the OFF operating status mode has been set. Any ignition request is ignored except for the frost-protection function.
The pump anti-lock, 3-way valve and frost protection functions remain active.
This icon indicates that WINTER mode has been selected (HEATING function enabled). If a heating request from the main zone is in progress, the icon will be flashing.
This icon indicates that the circuit for domestic hot water production is enabled. When a domestic hot water request is in progress, the icon
flashes. The P at the top of the domestic hot water icon indicates that the boiler preheating function is enabled; the P when flashing indicates
that a preheating request is in progress.
When the “embedded clock ” is enabled this icon indicates that the system heating (main zone) is in AUTOMATIC mode (the management
of the heating requests follows the ON/OFF times that have been programmed).
If the heating function is not enabled during the current time frame, the icon will be crossed out.
When the “central heating programming timing” is enabled this icon indicates that the system heating (main zone) is in MANUAL mode (the
management of the heating requests does not follow what has been set with the programming timing, but it is always active).

This icon indicates that the system (main zone) has been set to off (not active).
This icon indicates that the system is detecting the presence of a flame.
This icon indicates the presence of an anomaly, and is always flashing.
Pressing the keys “up” and “down” it is possible to choose
from among the following options:
• PLANT: the display will indicate the temperature of the
domestic hot water sensor rather than the flow sensor of
the boiler
• STATE/BOILER: enables access to choose the operating
mode of the appliance: OFF, Summer, Winter
• STATE/MAIN ZONE (if embedded clock disabled): enables
access to choose the operating mode (On or OFF) of the
main heating zone
• STATE/MAIN ZONE (if embedded clock is enabled):
enables access to choose operating mode of the embedded
clock (AUTO, MANUAL, OFF)
• SET: to view or adjust the heating or hot water setpoint
value or to enable or disable preheating
• INFO: to view the current values or status of the various
appliance inputs/sensors
• MENU: to access the system’s configuration menus
The configuration MENU is organised with a multi-access
level tree structure. With the “ok” key you can access the
selected submenu, with the “up” and “down” keys it is
possible to navigate through the submenus, while the “back”
key takes you back to the previous level.
An access level has been fixed for each submenu: USER level,
always available; TECHNICAL level, password protected.

INSTALLATION OF BOILERS OF RATED INPUT NOT EXCEEDING 70kW
LOW PRESSURE INSTALLATION PIPES
This appliance must be installed by a competent person
in accordance with the Gas Safety (Installation & Use)
Regulations.
4.1 RELATED DOCUMENTS
The installation of this boiler must be in accordance with the
relevant requirements of the Gas Safety (Installation & Use)
Regulations, the local building regulations, the current I.E.E.
wiring regulations, the bylaws of the local water undertaking,
the Building Standards (Scotland) Regulation, and Building
Standards (Northern Ireland) Regulations.
It should be in accordance also with any relevant requirements
of the local authority and the relevant recommendations of the
following British Standard Codes of Practice.
4.2 LOCATION OF APPLIANCE
The appliance may be installed in any room or internal space,
although particular attention is drawn to the requirements
of the current I.E.E. wiring regulations, and in Scotland, the
electrical provisions of the Building Regulations, with respect
to the installation of the appliance in a room or internal space
containing a bath or shower.
When an appliance is installed in a room or internal space
containing a bath or shower, the appliance or any control
pertaining to it must not be within reach of a person using the
bath or shower (refer to IEE regs).
The location chosen for the appliance must permit the provision
of a safe and satisfactory flue and termination. The location
must also permit an adequate air supply for combustion
purposes and an adequate space for servicing and air
circulation around the appliance. Where the installation of the
appliance will be in an unusual location special procedures
may be necessary, BS 6798 gives detailed guidance on this
aspect.
A compartment used to enclose the appliance must be
designed and constructed specifically for this purpose. An
existing compartment/cupboard may be utilised provided that
it is modified to suit.
Details of essential features of compartment/cupboard design
including airing cupboard installations are given in BS 6798.
This appliance is not configured for external installation
applications.
4.3 GAS SUPPLY
The gas meter – as supplied by the gas supplier – must be
checked to ensure that it is of adequate size to deal with
the maximum rated input of all the appliances that it serves.
Installation pipes must be fitted in accordance with BS 6891.
Pipe work from the meter to the appliance must be of adequate
size. Pipes of a smaller size than the appliance gas inlet
connection must not be used. The installation must be tested
for soundness in accordance with BS6891.
If the gas supply serves more than one appliance, it must
be ensured that an adequate supply is maintained to each
appliance when they are in use at the same time.
NOTE
It is recognised that ‘pressure loss’ through the gas cock and
gas valve may result in a pressure drop of approximately
2mbar between the gas meter and gas valve inlet test
point; this will not impair the performance of the appliance,
provided that a dynamic pressure of 18mbar is available at
the appliance inlet.
4.4 FLUE SYSTEM
The terminal should be located where the dispersal of combustion
products is not impeded and with due regard for the damage
and discoloration that may occur to building products located
nearby. The terminal must not be located in a place where it is
likely to cause a nuisance (see fig. 5).
In cold and/or humid weather, water vapour will condense
on leaving the terminal; the effect of such pluming must be
considered.
If installed less than 2m above a pavement or platform to which
people have access (including balconies or flat roofs) the terminal
must be protected by a guard of durable material. The guard
must be fitted centrally over the terminal. Refer to BS 5440
Part 1, when the terminal is 0.5 metres (or less) below plastic
guttering or 1 metre (or less) below painted eaves.
4.5 AIR SUPPLY
The following notes are intended for general guidance only. This
appliance is a room-sealed, fan-flued boiler, consequently it
does not require a permanent air vent for combustion air supply.
When installed in a cupboard or compartment, ventilation for
cooling purposes is also not required.
4.6 WATER CIRCULATION
Detailed recommendations are given in BS 5449 Part 1 and
BS 6798. The following notes are for general guidance only.
4.6.1 PIPEWORK
It is recommended that copper tubing to BS 2871 Part 1 is used
in conjunction with soldered capillary joints. Where possible
pipes should have a gradient to ensure air is carried naturally to
air release points and that water flows naturally to drain cocks.
Except where providing useful heat, pipes should be insulated
to avoid heat loss and in particular to avoid the possibility of
freezing. Particular attention should be paid to pipes passing
through ventilated areas such as under floors, loft space, and
void areas.
4.6.2 AUTOMATIC BY-PASS
The appliance has a built-in automatic by-pass, consequently
there is no requirement for an external by-pass, however the
design of the system should be such that it prevents boiler
‘cycling’.
4.6.3 DRAIN COCKS
These must be located in accessible positions to facilitate
draining of the appliance and all water pipes connected to the
appliance. The drain cocks must be manufactured in accordance
with BS 2879.
4.6.4 AIR RELEASE POINTS
These must be positioned at the highest points in the system
where air is likely to be trapped. They should be used to expel
trapped air and allow complete filling of the system.
4.6.5 EXPANSION VESSEL
The appliance has an integral expansion vessel to accommodate
the increased volume of water when the system is heated.
Refer to the specification table for more detailed information.
4.6.6 FILLING POINT
A method for initial filling of the system and replacing water lost
during servicing etc. directly from the mains supply, is provided
(see fig. 6). This method of filling complies with the current
Water Supply (Water Fittings) Regulations 1999 and Water
Bylaws 2000 (Scotland).
4.6.7 LOW PRESSURE SEALED SYSTEM
An alternative method of filling the system would be from an
independent make-up vessel or tank mounted in a position at
least 1 metre above the highest point in the system and at least
5 metres above the boiler (see fig. 7).
The cold feed from the make-up vessel or tank must be fitted
with an approved non-return valve and stopcock for isolation
purposes. The feed pipe should be connected to the return pipe
as close to the boiler as possible.
25
Frequent filling or venting of the system may be indicative
of a leak. Care should be taken during the installation of the
appliance to ensure all aspects of the system are capable of
withstanding pressures up to at least 3 bar.
4.7 ELECTRICAL SUPPLY
The appliance is supplied for operation on 230V @ 50Hz electrical
supply; it must be protected with a 3-amp fuse (supplied). The
method of connection to the mains electricity supply must allow
for complete isolation from the supply. The preferred method is
by using a double-pole switch with a contact separation of at
least 3mm. The switch must only supply the appliance and its
corresponding controls, i.e. time clock, room thermostat, etc.
Alternatively an un-switched shuttered socket with a fused 3-pin
plug both complying with BS 1363 is acceptable.
Warning!
This appliance must be earthed.
4.8 MOUNTING ON A COMBUSTIBLE SURFACE
4.11SHOWERS
If the appliance is intended for use with a shower, the shower
should be thermostatically controlled and be suitable for use
with a combination boiler.
This appliance must be installed by a competent person in
accordance with and defined by, the Standard Specification
(Domestic Gas Installations) Declaration (I.S. 813).

pertaining to it must not be within reach of a person using the
bath or shower.
The location chosen for the appliance must permit the provision
of a safe and satisfactory flue and termination. The location must
also permit an adequate air supply for combustion purposes
and an adequate space for servicing and air circulation around
the appliance. Where the installation of the appliance will be
in an unusual location special procedures may be necessary,
refer to I.S. 813 for detailed guidance on this aspect.
26
A compartment used to enclose the appliance must be
designed and constructed specifically for this purpose. An
existing compartment/cupboard may be utilised provided that
it is modified to suit.
This appliance is not configured for external installation.
4A.3GAS SUPPLY
The gas meter – as supplied by the gas supplier – must be
checked to ensure that it is of adequate size to deal with
the maximum rated input of all the appliances that it serves.
Installation pipes must be fitted in accordance with I.S. 813.
Pipe work from the meter to the appliance must be of adequate
size. Pipes of a smaller size than the appliance gas inlet
connection must not be used. The installation must be tested
for soundness in accordance with I.S. 813.
If the gas supply serves more than one appliance, it must
be ensured that an adequate supply is maintained to each
appliance when they are in use at the same time.
NOTE
It is recognised that ‘pressure loss’ through the gas cock and
gas valve may result in a pressure drop of approximately
2mbar between the gas meter and gas valve inlet test
point; this will not impair the performance of the appliance,
provided that a dynamic pressure of 18mbar is available at
the appliance inlet.
4A.4FLUE SYSTEM
The terminal should be located where the dispersal of combustion
products is not impeded and with due regard for the damage
and discoloration that may occur to building products located
nearby. The terminal must not be located in a place where it is
likely to cause a nuisance (see I.S. 813).
In cold and/or humid weather, water vapour will condense
on leaving the terminal; the effect of such pluming must be
considered.
If installed less than 2m above a pavement or platform to
which people have access (including balconies or flat roofs)
the terminal must be protected by a guard of durable material.
The guard must be fitted centrally over the terminal. Refer to
I.S. 813, when the terminal is 0.5 metres (or less) below plastic
guttering or 1 metre (or less) below painted eaves.
4A.5AIR SUPPLY
The following notes are intended for general guidance only.
This appliance is a room-sealed, fan-flued boiler, consequently it
does not require a permanent air vent for combustion air supply.
When installed in a cupboard or compartment, ventilation for
cooling purposes is also not required.
4A.6WATER CIRCULATION
Specific recommendations are given in I.S. 813. The following
notes are for general guidance only.
4A.6.1 PIPEWORK
It is recommended that copper tubing be used in conjunction
with soldered capillary joints..
Where possible pipes should have a gradient to ensure air
is carried naturally to air release points and that water flows
naturally to drain cocks.
Except where providing useful heat, pipes should be insulated
to avoid heat loss and in particular to avoid the possibility of
freezing. Particular attention should be paid to pipes passing
through ventilated areas such as under floors, loft space, and
void areas.
4A.6.8 FREQUENT FILLING
Frequent filling or venting of the system may be indicative
of a leak. Care should be taken during the installation of the
appliance to ensure all aspects of the system are capable of
withstanding pressures up to at least 3 bar.
4A.7ELECTRICAL SUPPLY
The appliance is supplied for operation on 230V @ 50Hz electrical
supply; it must be protected with a 3-amp fuse (supplied). The
method of connection to the mains electricity supply must allow
for complete isolation from the supply. The preferred method is
by using a double-pole switch with a contact separation of at
least 3mm. The switch must only supply the appliance and its
corresponding controls, i.e. time clock, room thermostat, etc.
Alternatively an un-switched shuttered socket with a fused 3-pin
plug both complying with BS 1363 is acceptable.
Warning!
This appliance must be earthed.
4A.8MOUNTING ON A COMBUSTIBLE SURFACE
The appliance can be mounted on a wall of combustible material
without any requirement to fit any additional protective (fireresistant) material.
4A.9TIMBER FRAMED BUILDINGS
If the appliance is to be fitted in a timber framed building, it
should be fitted in accordance with I.S. 813 and local Building
Regulations.
The Institute of Gas Engineers publication (IGE/UP/7) ‘Guide
for Gas Installations in Timber Frame Buildings’ gives specific
advice on this type of installation.
4A.10 WATER TREATMENT
The appliance has a built-in automatic by-pass, consequently
there is no requirement for an external by-pass, however the
design of the system should be such that it prevents boiler
‘cycling’.
Vokera recommend that water treatment be carried out in
accordance with the Benchmark Guidance on water treatment
in central heating systems. If water treatment products are to
be used, then they must be entirely suitable for use with an
aluminium heat exchanger. Any water treatment product, must
be administered in strict accordance with the manufacturer’s
instructions.
If the appliance is to be installed to an existing system; water
treatment and flushing of the complete heating system should
be carried out in accordance with BS 7593 and the Benchmark
Guidance on water treatment in central heating systems.
4A.6.3 DRAIN COCKS
4A.11SHOWERS
4A.6.2 AUTOMATIC BY-PASS
These must be located in accessible positions to facilitate
draining of the appliance and all water pipes connected to the
appliance.
4A.6.4 AIR RELEASE POINTS
These must be positioned at the highest points in the system
where air is likely to be trapped. They should be used to expel
trapped air and allow complete filling of the system.
4A.6.5 EXPANSION VESSEL
The appliance has an integral expansion vessel to accommodate
the increased volume of water when the system is heated.
Refer to the specification table for more detailed information.
If the appliance is intended for use with a shower, the shower
should be thermostatically controlled and be suitable for use
with a combination boiler.
4A.12 DECLARATION OF CONFORMITY
A Declaration of Conformity (as defined in I.S. 813) must be
provided on completion of the installation.
A copy of the declaration must be given to the responsible
person and also to the gas supplier if required.
4A.6.6 FILLING POINT
A method for initial filling of the system and replacing water lost
during servicing etc. is provided (see fig. 6). You should ensure
this method of filling complies with the local water authority
regulations.
4A.6.7 LOW PRESSURE SEALED SYSTEM
An alternative method of filling the system would be from an
independent make-up vessel or tank mounted in a position
at least 1 metre above the highest point in the system and at
least 5 metres above the boiler (see fig. 7). The cold feed from
the make-up vessel or tank must be fitted with an approved
non-return valve and stopcock for isolation purposes. The feed
pipe should be connected to the return pipe as close to the
boiler as possible.

5.6.6 CONDENSATE DISPOSAL
Fig. 19
This appliance will - under normal operating conditions - produce
condensate fluid that will require to be disposed of via the
dwelling’s waste water drainage system.
Vokera strongly recommends that the condensate pipe is
connected to the internal waste water pipework in accordance
with BS6798.
31
BS6798 provides comprehensive instruction and advice on all
permissible condensate disposal methods; notwithstanding this,
it is essential that the following is strictly adhered to:
- use only plastic drainage pipe (minimum OD of 21.5mm)
- horizontal runs must incorporate a minimum 45mm fall per
metre, away from the appliance
- external pipework and/or pipework in unheated areas, must
have a minimum OD of 32mm and be insulated with Class-O
pipe insulation
- the route, type, and termination of the condensate disposal
method, must not permit any spillage of condensate fluid,
into the dwelling in the event of a blockage or freezing of the
condesate pipework.
Should it not be possible to route and terminate the condensate
pipework internally using ‘gravity discharge’; Vokera
recommends that the Vokera condensate pump (code 404) be
considered as an alternative solution.
Ensure that the end-user is aware of the effect/consequences
of the condensate pipework becoming blocked or frozen.

possible to remove and replace the ‘fly-lead’ with an alternative
method of connection to the electrical supply.
5.7.3 CONNECTING A 230V SUPPLY TO THE
APPLIANCE PCB
WARNING
Isolate the appliance from the electrical supply before
carrying out this procedure.
Remove the front cover as detailed in 5.7.1. Locate the red
clip that retains the control panel in the upright position and
move it to the left to release the control panel.
Lower the control panel and remove the two PCB cover
retaining screws (located adjacent to the PCB’s front retaining
clips).
Push in the two front clips, and pull out the side clip in order
to release the cover and then remove the cover - lifting from
the front upwards.
The 230v electrical supply input is located at the rear right
hand side of the PCB (see Section-8 schematics); disconnect
and remove the factory-fitted fly-lead, and use the same
cable-entry point, route, and respective electrical terminals for
the new 230v supply cable.

of the ‘room-sealed’ element of the appliance; any
damage that results in a loss of their integrity will
require the replacement of the cover.
Replace the appliance front cover as detailed in 5.7.1 paying
attention to the importance of ensuring the cover is providing
an effective seal.
bbThe front cover and side panels are an intrinsic part
bbThe noise absorbing panels that are located inside
the front cover and side panels also act as seals to
ensure airtightness and the room-sealed integrity of
the appliance. It is essential that these are correctly
positioned during the refitting of the front cover
and/or side panels. Any subsequent damage or
deterioration to the noise absorbing panels must be
rectified before the appliance is put back into service.
Refit the PCB cover screws and move the control panel back
to the upright position ensuring the red securing clip, clicks
into place.
NOTE
It is the installer and/or electrician’s responsibility to ensure
that the appliance properly earthed. Vokera Ltd. cannot

6.2.4 SETTING THE THERMOREGULATION
Thermoregulation (weather compensation) controlled by the
appliance, can only be enabled if an external sensor has been
installed and connected to the D-sub interface (SE terminals
11 & 12).
When the presence of an external sensor is detected, the
appliance immediately enables the thermoregulation function
and calculates a required outlet (flow) temperature that is
based on the external temperature and the chosen climatic
curve.
The temperature measured by the outdoor temperature
sensor is displayed on the initial page in the top right,
alternating with the display of the time.
When thermoregulation is enabled (outdoor temperature
sensor present), the algorithm for automatically calculating
the outlet setpoint depends on the type of heat request.
THERMOREGULATION
RANGE RATED
CALIBRATION
INSTALLER
Using the REC10 it is possible to set the value of the following
parameters:
BUILDING TYPE
It is indicative of the frequency with which the value of
the calculated outdoor temperature for thermoregulation is
updated, a low value for this setting will be used for buildings
that have little insulation.
Setting range: [5min - 20min]
Factory setting:[5min]
REACTIVITY EXT SENSOR
It is an indication of the speed with which variations of the
measured outdoor temperature affect the calculated outdoor
temperature value for thermoregulation, low values indicate
high speeds.
Setting range: [0 - 255]
Factory setting: [20]
At this point, to change the value of the previous parameters,
proceed as described below:
-- in sequence select THERMOREGULATION and TYPE OF
BUILDING rather than REACTIVITY EXT SENSOR with the
“up” and “down” keys, confirming the selection
-- set the desired value with the “up” and “down” keys,
confirming the selection.
Note: The value of the calculated outdoor temperature used
by the thermoregulation algorithm is displayed in the INFO
menu under T EXT FOR THERMOREG.
HEAT REQUEST FROM THERMOSTAT or POR
(Programmable Timer)
In this case the outlet setpoint depends on the outdoor
temperature for obtaining a reference ambient temperature of
20°C. There are 2 parameters that compete to calculate the
output setpoint:
-- slope of the compensation curve (KT)
-- offset on the reference ambient temperature.
SELECTING THE COMPENSATION CURVE
The compensation curve for heating maintains a theoretical
temperature of 20°C indoors, when the outdoor temperature
is between +20°C and -20°C. The choice of the curve
depends on the minimum outdoor temperature envisaged
(and therefore on the geographical location), and on the
delivery temperature envisaged (and therefore on the type of
system). It is carefully calculated by the installer on the basis
of the following formula:
KT = T. outlet envisaged - Tshift
20- min. design external T
Tshift =30°C standard system
25°C floor installations
If the calculation produces an intermediate value between two
curves, you are advised to choose the compensation curve
nearest the value obtained.
Example: if the value obtained from the calculation is 1.3, this
is between curve 1 and curve 1.5. Choose the nearest curve,
i.e. 1.5.
The settable KT values are as follows:
radiator system: 1.0-3.0
under floor heating system 0.2-0.8.

OFFSET ON THE REFERENCE AMBIENT TEMPERATURE
In any event, the user can indirectly modify the value of
the HEATING setpoint inserting an offset on the reference
temperature that can vary within the range -5-+5 (offset 0 =
20°C).
NIGHT COMPENSATION
Whenever a programmable timer is connected to the
ROOM THERMOSTAT input, from the TECHNICAL\
THERMOREGULATION\CLIMATIC CURVES\MAIN the
NIGHT COMPENSATION function can be enabled.
In this case, when the CONTACT is CLOSED, the heat
request is made by the flow sensor, on the basis of the outdoor
temperature, to obtain a nominal ambient temperature on
DAY level (20°C).
The opening of the contact does not produce a switch-off,
but a reduction (parallel translation) of the climatic curve on
NIGHT level (16°C).
Also in this case, the user can indirectly modify the value of
the HEATING setpoint inserting once again an offset on the
reference DAY temperature (20°C) rather than NIGHT (16°C)
that can vary within the range [-5 - +5].
DELIVERY TEMPERATURE (°C)
In any case, the thermoregulation algorithm will not directly
use the outdoor temperature, but rather a calculated outdoor
temperature that takes into account the building’s insulation:
in buildings that are well insulated, the outdoor temperature
variations will have less impact than those that are poorly
insulated by comparison. Enabling THERMOREGULATION

by the REC10, should all 3 attempts at reset fail, the appliance
will require to be isolated briefly from the electrical supply
in order to carry out any further reset attempts. Once the
electrical supply supply has been restored, further attempts at
reset can be carried out.
For fault E060
The boiler is working normally, but does not provide any
stability of the domestic hot water temperature that, in any
event, is supplied at a temperature of around 50°C. The
intervention of an engineer will be required.
For fault E091
The boiler has an auto-diagnostic system which, based on
the total number of hours in certain operating conditions, can
signal the need to clean the primary exchanger (alarm code
E091). Once the cleaning operation has been completed,
reset to zero the total hour meter with special kit supplied as

bbIn case where, after the replacement of the electronic
board or the maintenance of the detection electrode or
the burner, the combustion analysis would restore out of
tolerance values, it may be necessary to take action on
the parameter COMBUSTION OFFSET as described in
the section “6.18 Combustion check parameters”.
Note: in case of replacement of the electrode, slight
variations of the combustion parameters can not be
excluded. These data wil return to nominal values after
a few hours of operation.
bbDo not clean the appliance or its parts with inflammable
substances (e.g. petrol, alcohol, etc.).
bbDo not clean panels, painted parts and plastic parts with
paint thinner.
bbPanel cleaning must be carried out only with soapy
water.
Maintenance of the combustion control system
Maintenance electrode
The detection electrode/ionization sensor has an important
function in the boiler ignition phase and in the maintenance of
a proper combustion; in this context, in case of replacement,
it is necessary to always ensure that it is correctly positioned
and to strictly observe the reference shown in the figure.

SECTION 7 - SERVICING INSTRUCTIONS
7.1GENERAL
Once the appliance has been serviced, the benchmark Service
Record must be completed.
For UK only
It is important that the Benchmark Service Record is correctly
completed and handed to the user. Failure to install and
commission the appliance to the manufacturers instructions
will invalidate the warranty.
To ensure the continued safe and efficient operation of the
appliance, it is recommended that it is checked and serviced
at regular intervals. To ensure correct and safe operation of the
appliance, it is essential that any worn or failed component be
replaced only with a genuine Vokèra spare part. It should be
remembered that although certain generic components may
look similar, they will be specific to an individual appliance
or product range. Use of non-genuine Vokèra spare parts
could invalidate your warranty and may pose a potential
safety hazard. The frequency of servicing will depend upon
the particular installation conditions, but in general, once per
year should be sufficient. It is the law that any servicing work
is carried out by competent person such as a Vokèra engineer,
an approved service agent, British Gas, GAS SAFE registered
personnel or other suitably qualified personnel. The following
instructions apply to the appliance and its controls, but it should
be remembered that the central heating and the domestic hot
water systems would also require attention from time to time.
7.2ROUTINE ANNUAL MAINTENANCE
The
appliance
incorporates
many
‘state-of-the-art’
components that are either ‘solid-state’ or are regarded as
‘non-serviceable’ items. As a consequence, the requirements
for routine annual maintenance are focussed upon:
1. ensuring that the appliance and flue system are in a safe
condition
2. ensuring that the appliance is operating safely
3.ensuring that the appliance is performing to its design
specification.
When the appliance has been installed to within the minimum
stated clearances; the appliance layout is such that it enables
routine annual maintenance to be carried out entirely from the
front of the appliance.
NOTE
Any noticeable defect or deterioration on or within the
appliance and flue system that impacts or affects the above
requirements; will warrant further diagnosis and repair, which
may result in the replacement of components.
Specific advice and instruction on the removal and replacement
of component parts of the appliance can be found in the

SECTION 8 - CHECKS, ADJUSTMENTS AND FAULT FINDING
8.1 CHECKING APPLIANCE OPERATION
When carrying out any repairs or servicing to the appliance,
the relevant commissioning procedure must be undertaken to
ensure the continued safe operation of the appliance. Particular
attention should be made to ensure gas tightness, water
tightness and the electrical integrity of the appliance.
8.2 APPLIANCE MODES OF OPERATION
NOTE
There must be sufficient system water pressure (min. 0.5 bar)
to ensure the water pressure switch is activated. If there is
insufficient system pressure the pump and fan will be prevented
from operating and the low-pressure fault code will be indicated.
8.2.1 OFF
When the appliance has been set to OFF via the REC10 UI,
the following functions will remain active:
• frost-protection system
• pump & actuator anti-block.
8.2.2 ON-BOARD FUNCTIONS
• FROST-PROTECTION: this function is only active when
there are no requests for heating or HW. If the temperature
drops below 5°C, the boiler will operate on minimum power
until the temperature of the thermistors reaches 35°C for CH
and 55°C for DHW. Thereafter the pump & fan will over-run
for 30-seconds.
• ANTI-CYCLE FUNCTION: the anti-cycle function ensures the
burner remains switched off for at least 3-minutes after the
set-point hysterisis (set-point + 5-deg) for CH heat request.
• PUMP ANTI-BLOCK FUNCTION: when there has been no
heating or HW request for 24-hours, the anti-block cycle
is activated. The pump will be activated for a period of
30-seconds.
• ACTUATOR ANTI-BLOCK FUNCTION: when there has been
no heating or HW request for 24-hours, the anti-block cycle
is activated. The divertor valve actuator will motor briefly to
the heating position, and then back to the DHW position. The
pump will run briefly.
• DHW PRE-HEAT FUNCTION: when the DHW pre-heat
function is enabled, the appliance will light periodically to
maintain the temperature of the DHW heat exchanger. When
the DHW thermistor and the primary thermistor fall below 35°C
and 55°C respectively, the boiler will fire on minimum +25%
power until the primary thermistor exceeds 55°C. Thereafter
the pump will over-run for a period of 30-seconds.
8.2.3 HEATING MODE
When a ‘heating’ request is generated via the connected
external control/s and/or the REC10 UI, the appliance will
operate in the heating mode. The pump and fan will be activated
via the flow temperature sensor. When the fan is sensed to
be operating correctly (tacho signal), the ignition sequence
commences. Ignition is sensed by the electronic circuit to
ensure flame stability at the burner. Once successful ignition
has been achieved, the electronic circuitry increases the gas
rate to 75% for a period of 15 minutes.
The speed of the fan and therefore the output of the boiler is
determined by the temperature of the water sensed by the
flow temperature sensor, consequently a high temperature
at the flow sensor results in a lower fan speed. As the water
temperature increases, the temperature sensors – located
on the flow pipe of the boiler – reduce the fan speed via the
electronic circuitry. Depending on the load, either the water
temperature will continue to rise until the set point is achieved or
the water temperature will fall whereby fan speed will increase
relative to the output required. When the boiler has reached
the set point (+ hysterisis), the burner will switch off. The builtin anti-cycle device prevents the burner from re-lighting for
approximately 3-minutes.
When the temperature of the flow sensor falls below the set
point (- hysterisis), the burner will re-light.
NOTE
If burner ignition is not detected at the first attempt, the appliance
will repeat the ignition sequence another two times (3-times
in total) before going to lockout. When the set-point has been
reached as measured at the primary thermistor, the appliance
will begin the modulation phase whereby the fan and gas valve
will continuously modulate to maintain the set-point.
If the temperature continues to rise and exceeds the set-point
by 5°C (hysterisis), the burner will shut down. A new ignition
sequence will be enabled when the 3- minute anti-cycle has
been performed and the temperature at the primary thermistor
has dropped 5°C (hysterisis) below the set-point.
8.2.4 DHW MODE
The appliance will operate in the hot water mode whenever
a DHW outlet is opened. The appliance flowmeter will detect
water movement (min 2L/pm) and signal a hot water request
whereupon the pump and fan will be activated via the flow
temperature sensor. When the fan is sensed to be operating
correctly (tacho signal), the ignition sequence commences.
Ignition is sensed by the electronic circuitry to ensure flame
stability at the burner. Once successful ignition has been
achieved, the electronic circuit allows the gas rate to achieve
the modulation value.
NOTE
When the request for heating and/or hot water has been
satisfied, the appliance pump and fan may continue to circulate
to dissipate any residual heat within the appliance.
ATTENTION
Gas type and appliance outputs are factory set by default, at
the values declared in the specification data in section 2.
Vokera cannot accept any responsibility for any damage or
malfunction that has been caused as a result of tampering
or incorrect set up of this appliance during installation or
commissioning.
8.3 CHECKING THE EXPANSION VESSEL
Carry out the component removal procedure as described in
7.4. You must ensure that the boiler is completely drained of
water. Using a suitable pressure gauge, remove dust cap on
expansion vessel and check the charge pressure. The correct
charge pressure should be 1.0 bar ± 0.1 bar. If the charge
pressure is less, use a suitable pump to increase the charge.
NOTE
You must ensure the drain valve is in the open position whilst
re-charging takes place. Replace the dust cap and carry out
the relevant commissioning procedure (section 6).
8.4 EXTERNAL FAULTS
Before carrying out any faultfinding or component replacement,
ensure the fault is not attributable to any aspect of the installation.

8.5 ELECTRICAL CHECKS
Any electrical checks must be carried out by a suitably qualified
person.
8.5.1 EARTH CONTINUITY TEST
Isolate the appliance from the electrical supply, and using a
suitable multi-meter carry out a resistance test. Connect test
leads between an appliance earth point and the earth wire of
the appliance supply cable. The resistance should be less than
1 OHM. If the resistance is greater than 1 OHM check all earth
wires and connectors for continuity and integrity.
8.5.2 SHORT CIRCUIT CHECK
Isolate the appliance from the electrical supply, and using a
suitable multi-meter, carry out a short circuit test between the
Live & Neutral connections at the appliance terminal strip.
Repeat above test on the Live & Earth connections at the
appliance terminal strip.
NOTE
Should it be found that the fuse has failed but no fault is
indicated, a detailed continuity check will be required to trace
the fault. A visual inspection of components may also assist in
locating the fault.
8.5.3 POLARITY CHECK
With the appliance connected to the electrical supply and using
a suitable multimeter, carry out the following voltage tests:
• connect test leads between the Live & Neutral connections
at the appliance terminal strip. The meter should read
approximately 230V ac. If so proceed to next stage. If not,
see 8.6.
• connect test leads between the Live & Earth connections at the
appliance terminal strip. The meter should read approximately
230V ac. If so proceed to next stage. If not, see 8.6.
• connect test leads between the Neutral & Earth connections
at the appliance terminal strip. The meter should read
approximately 0 – 15Vac. If so polarity is correct. If not, see
8.6.
8.5.4 REVERSED POLARITY OR SUPPLY FAULT
Repeat the above tests at the appliance isolator, if testing
reveals correct polarity and/or supply at the isolator, re-check
wiring and connections between the isolator and the appliance.
If tests on the isolator also reveal reversed polarity or a supply
fault, consult the local electricity supplier for advice.
DISTANCE TO EARTH CHECK
Isolate the appliance from the electrical supply, and using a
suitable multi-meter carry out a resistance test. Connect test
leads between the Live & Earth connections at the appliance
terminal strip. If the meter reads other than infinity there is a
fault that must be isolated, carry out a detailed continuity check
to identify the location of the fault.
These series of checks must be carried out before attempting
any faultfinding procedures on the appliance. On completion
of any task that required the disconnection and re-connection
of any electrical wiring or component, these checks must be
repeated.
8.6 FAULT FINDING
Before attempting any faultfinding, the electrical checks as
detailed in 8.5 must be carried out. Isolate the appliance from
the electrical supply.
Disconnect any external controls from terminal plug, and insert
a link-wire between the two wires at the ‘TA’ connections of the
D-sub interface.
NOTE
Restore the electrical supply to the boiler and RESET
functionning. The boiler should now function as described
in section 8.2. Should the boiler fail to respond, the internal
fuses and connectors should be checked to ensure integrity
and continuity.
58
8.7 APPLIANCE STATUS AND FAULT CODES
When the boiler detects a temporary fault condition, the
appropriate code is shown. If/when the fault is final, the pump
will perform 30 to 60-second post circulation (depending on the
error code) and fault code will be displayed. For combustion
fault, FAN can also post vent up to 5min if required.

COMMISSIONING: CO AND COMBUSTION RATIO CHECK
BEFORE CO AND COMBUSTION RATIO CHECK
The installation instructions should have been followed, gas
type verified and gas supply pressure/rate checked as required
prior to commissioning.
As part of the installation process, ESPECIALLY WHERE A
FLUE HAS BEEN FITTED BY PERSONS OTHER THAN THE
BOILER INSTALLER, visually check the integrity of the whole
flue system to confirm that all components are correctly
assembled, fixed and supported. Check that the maximum flue
lengths have not been exceeded and all guidance has been
followed (e.g. Technical Bulletin 008).
The flue gas analyser should be of the correct type, as specified
by BS 7967.
Before use, the flue gas analyser should have been maintained
and calibrated as specified by the manufacturer. The installer
must have the relevant competence for use of the analyser.
Check and zero the analyser IN FRESH AIR, as per analyser
manufacturer’s instructions.
NOTE
The air/gas ratio valve is factory-set and must not be
adjusted during commissioning unless this action is
recommended, following contact with the Vokera
technical help line. If any such adjustment is
recommended and further checking of the boiler is
required, the engineer must be competent to carry out
this work and to use the flue gas analyser accordingly.
If the boiler requires conversion to operate with a
different gas family (e.g., conversion from natural gas
to LPG) separate guidance will be provided by the
Vokera technical help line and must be followed.
SET BOILER TO MAXIMUM RATE
In accordance with, section 7.3, set boiler to operate at maximum rate (full load condition). Allow sufficient time for combustion to
stabilise. , insert analyser probe into air inlet sampling point.
Verify flue integrity
Analyser readings indicate
that combustion products
and inlet air are mixing.
Further investigation of the
flue is therefore required.
Check that flue components
are correctly assembled,
fixed and supported as per
boiler/flue instructions.
Check that flue and flue
terminal are not obstructed.
Turn off appliance and call
Vokera’s technical helpline
for advice.
The appliance must not be
commissioned until
problems are identified and
resolved. If commissioning
cannot be fully completed,
the appliance must be
disconnected from the gas
supply in accordance with
the GSIUR.
NOTE: Check and record CO and
combustion ratio at both
maximum AND minimum rate

Benchmark Commissioning and
Servicing Section
It is a requirement that the boiler is installed and commissioned to the
manufacturers instructions and the data fields on the commissioning checklist
completed in full.
To instigate the boiler guarantee the boiler needs to be registered with the
manufacturer within one month of the installation.
To maintain the boiler guarantee it is essential that the boiler is serviced annually
by a Gas Safe registered engineer who has been trained on the boiler installed.
The service details should be recorded on the Benchmark Service Interval
Record and left with the householder.
