USERS INSTRUCTIONS

INTRODUCTION

Dear Customer Your Vokèra evolve boiler has been designed to meet and exceed the very latest standards in gas central heating technology,

and if cared for, will give years of reliable use and e󰀩ciency.

Please therefore take some time to read these instructions carefully.

Do’s and Don’t’s

- Do ensure that the system pressure is periodically checked

- Do ensure that the boiler is not used by children or unassisted disabled people

- Do ensure that you know how to isolate the appliance in an emergency

- Do ensure that you are familiar with the appliance controls

- Do ensure that your installer has completed the appliance log book section

- Do not attempt to remove the appliance casing or gain internal access

- Do not hang clothes etc. over the appliance

- Do not forget to have the appliance serviced annually.

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 from Vokèra customer services.

At the end of its life, the product should be not be disposed of as solid urban waste, but rather it should be handed over to a

di󰀨erentiated waste collection centre.

1. THINGS YOU SHOULD KNOW

1.1 GAS APPLIANCES

Gas Safety (Installation and Use) Regulation (UK).

In the interests of your safety and that of 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 tted.

Warning: this appliance must be earthed!

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 conrmation 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 a󰀨ect your statutory rights.

Page 3

1.5 HOW DOES IT WORK?

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 tted. The boiler will light when it receives a request from

the time clock via any thermostat that may be installed. 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.

1.8 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 o󰀨 – 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.

* 100mm if rear-ue outlet is used or 25mm above ue bend

if top ue outlet is used. Consideration should be given to

providing reasonable clearance for the insertion of a FGA probe.

** Disconnection of adjacent components may be required in

order to facilitate syphon removal.

*** Provided that a door or removal panel enables 450mm

access for maintenance.

^ Can be reduced to 5mm if a removal panel enables 100mm

for maintenance.

E020

LIMIT THERMOSTAT

REC10 ATTEMPTS EXHAUSTED

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 lling valve connections (usually beneath the boiler, see g. 1).

- 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.

- Remove the lling loop from the connections.

3.2 HOW TO RESET THE APPLIANCE

Reset function

E020

- 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.

The 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.

Page 13

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, e󰀩ciency and

low emissions under any conditions. The ACC system uses an ionisation sensor immersed in the

burner ame, 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

di󰀨erent gas compositions, di󰀨erent outlet pipes lengths and di󰀨erent altitudes (within the specied 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 evolve product family comprises a range of high-e󰀩ciency combination and system 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 ue 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 Vokèra website - www.vokera.co.uk.

The boiler complies with basic requirements of the following Directives:

- Regulation (EU) 2016/426;

- 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;

- Regulation (EU) 2017/1369 Energy labeling;

- Delegated Regulation (EU) No. 811/2013;

- Delegated Regulation (EU) No. 813/2013.

At the end of its life, the product should be not be dis-

posed of as solid urban waste, but rather it should be handed over to a di󰀨erentiated waste collection centre.

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 ame supervision

• Integral high-head pump

• Fan

• Expansion vessel

• 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, if the main temperature falls to 5°C, the appliance will function on minimum power until the temperature on main reaches 35°C.

• anti-block function: the anti-block function enables the pump to be energised for short periods, when the appliance has been inactive for more than 24-hours.

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 ame 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 satised the appliance

pump and fan may continue to operate to dissipate any residual heat within the appliance.

1.4 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;

• ame sensor that will shut down the burner when no ame

signal is detected and/or when incomplete combustion or high emissions are detected;

• ue sensor that will shut down the burner if the ue threshold

temperature is exceeded;

• a safety valve which releases excess pressure from the primary circuit.

NOTE

When the appliance is rst 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.

BS 5440 PART 1 FLUES BS 5440 PART 2 FLUES & VENTILATION BS 5449 PART 1 FORCED CIRCULATION HOT WATER SYSTEMS

BS 6798 INSTALLATION OF BOILERS OF RATED INPUT NOT EXCEEDING 70kW BS 6891 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 ue 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 specically for this purpose. An

existing compartment/cupboard may be utilised provided that it is modied to suit. Details of essential features of compartment/cupboard design including airing cupboard installations are given in BS 6798.

This appliance is not congured 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 tted 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 g. 5).

In cold and/or humid weather, water vapour will condense

on leaving the terminal; the e󰀨ect of such pluming must be

considered. If installed less than 2m above a pavement or platform to which

people have access (including balconies or at roofs) the terminal

must be protected by a guard of durable material. The guard

must be tted 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-ued 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 ows 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 oors, 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 lling 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 specication table for more detailed information.

4.6.6 FILLING POINT

A method for initial lling of the system and replacing water lost

during servicing etc. directly from the mains supply, should be provided (see g. 6). This method of lling 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 lling 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 g. 7). The cold feed from the make-up vessel or tank must be tted

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.

Page 25

4.6.8 FREQUENT FILLING

Frequent lling 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

The appliance can be mounted on a wall of combustible material

without any requirement to t any additional protective (re-

resistant) material.

4.9 TIMBER FRAMED BUILDINGS

If the appliance is to be tted in a timber framed building, it should be tted in accordance with the Institute of Gas Engineers

publication (IGE/UP/7) ‘Guide for Gas Installations in Timber Frame Buildings’.

4.10 WATER TREATMENT

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 ushing 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.

5.6.4 CONDENSATE DISPOSAL

This appliance will - under normal operating conditions - produce

condensate uid 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. 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 uid,

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 e󰀨ect/consequences

of the condensate pipework becoming blocked or frozen.

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. 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 occurs in the following way:

- select THERMOREGULATION with the “up” and “down” keys, confirming the selection.

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.

Using the REC10 it is possible to set the selected thermoregulation curve:

- in sequence select THERMOREGULATION and CLIMATIC CURVES with the “up” and “down” keys, confirming the selection

- select the desired heating zone with the “up” and “down” keys, confirming the selection

- set the desired climatic curve with the “up” and “down” keys, confirming the selection.

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].

SECTION 7 - SERVICING INSTRUCTIONS

7.1 GENERAL

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 e󰀩cient 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 specic 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 su󰀩cient. 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 qualied 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.

7.2 ROUTINE 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 ue system are in a safe

condition

2. ensuring that the appliance is operating safely

3. ensuring that the appliance is performing to its design

specication.

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 su󰀩cient system water pressure (min. 0.5 bar)

to ensure the water pressure switch is activated. If there is

insu󰀩cient 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 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 o󰀨 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.

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 ow 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 ame 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

ow temperature sensor, consequently a high temperature at the ow sensor results in a lower fan speed. As the water

temperature increases, the temperature sensors – located

on the ow 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 o󰀨. The built-

in anti-cycle device prevents the burner from re-lighting for approximately 3-minutes.

When the temperature of the ow sensor falls below the set

point (- hysterisis), the burner will re-light.

NOTE

If burner ignition is not detected at the rst 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.

NOTE

When the request for heating and/or hot water has been

satised, 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 specication 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 faultnding or component replacement,

ensure the fault is not attributable to any aspect of the installation.

8.4.1 INSTALLATION FAULTS

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

INSTALLER

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 innity 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 faultnding 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 faultnding, 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.

Warning!–Failuretofollowthewiringcongurationsas

detailed below, may result in malfunction and/or internal damage to the appliance.

The evolve system boilers incorporate an internal relay that enables a direct switched 230v supply to be used to generate a heating or hot water request from an external control system such as Y-PLAN or S-PLAN.

To congure an S or Y PLAN control system with the evolve boiler, proceed as follows:

1. Isolate the appliance from the electrical supply and remove

the front cover as detailed in section 5.7.1. gain access to the appliance PCB as detailed 5.7.3

2. Identify the internal relay PCB (BE11), which is located to

the right hand side of the main control PCB

3. Route the external wiring from the Y-Plan/S-Plan control

system through one of the cable entry points that are located on the lower right-side of the appliance

4. Using the (below) relevant diagram as a reference, connect the switched 230v supply (Live & Neutral) from the external control system (Y-Plan/S-Plan) to the small PCB (BE11) at terminals CN1

5. Replace the PCB cover ensuring that no internal wiring is trapped or strained

6. Replace the appliance front cover as detailed in 5.7.1.

NOTE

• Under no circumstances should the Y-Plan/S-Plan wiring

be connected directly to the D-Sub interface and/or the TA connections.

• Ensure that the appliance and all other external controls, are

served and isolated from the same electrical supply/isolator

• Ensure that the cable entry point is suitably sealed with

silicone sealant or adhesive tape.

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.

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 before contacting the Vokera

In accordance with, section 7.3, set boiler to operate at maximum rate (full load condition). Allow sufficient time for combustion to

Benchmark Commissioning and Servicing Section

It is a requirement that the boiler is installed and commissioned to the

manufacturers instructions and the data elds 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.
