Using the boiler...

√ Before lighting the boiler you are advised to have a Gas Safety Registered Engineer check that the installation of the gas supply

• is gas-tight;
  • is of the correct gauge for the flow to the boiler;
  • is fitted with all the safety and control devices required by the current Regulations.

√ Ensure that

- Check with the Installer that he has connected and terminated the pressure relief valve in a manner which allows safe discharge. The manufacturers are not responsible for damage caused by opening of the pressure relief valve and consequent escape of water, if this is not connected and terminated.

- The installer has connected the condensate outlet to a suitable drain pipe.

√ On detecting the smell of gas:

• don't operate any electrical switches, the telephone or any device that may produce sparks;
• open the windows and doors at once to create a draught of air which will purge the area;
• shut off the gas cocks;
  • get the assistance of a qualified person. Emergency telephone number

Tel. [phone].

√ Do not touch the appliance with parts of the body that are wet or damp and/or bare feet.
√ Do not block or modify the condensate outlet and pipe work.
√ In case of structural work or maintenance near the exhaust duct and/or fume exhaust devices or their attachments, turn off the appliance. On completion of the work, have a professionally qualified person check their efficiency.
√ Repairs (under guarantee) must be carried out only by a Biasi an approved engineer, using genuine spare parts. Thus do no more than switching off the boiler yourself (see the instructions).
√ Your boiler allows heating up of water to a temperature less than boiling point;

- must be connected to a central heating system and/or a hot water supply system, compatible with its performance and output;

- can be used only for those purposes for which it has been specially designed;

- must not be touched by children or by those unfamiliar with its operation;

- must not be exposed to weather conditions.

√ During the operation it is quite normal that the boiler produces a white plume of condensation vapour from the flue terminal. This is due to the high efficiency of the appliance and may be particularly evident with low outdoor temperatures.

Safe handling of substances

Biasi products are manufactured in accordance with ISO 9001 and do not, and will not, contain any hazardous materials or substances such as asbestos, mercury or C.F.C.'s. The appliance packaging does not contain any substances, which may be considered a hazard to health.

When handling or lifting always use safe techniques.

• Keep your back straight, bend your knees, don't twist.
• Move your feet, avoid bending forwards and side way sand keep the load as close to your body as possible.

Where possible transport the boiler using a sack truck or other suitable trolley.

Always grip the boiler firmly, and before lifting feel where the weight is concentrated to establish the centre of gravity, repositioning yourself as necessary.

Combustion chamber panels

Material: mineral fibres

Known hazards - Some people can suffer reddening and itching of the skin. Fibre entry into the eye will cause foreign body irritation, which can cause severe irritation to people wearing contact lenses. Irritation to respiratory tract.

Precautions - Dust goggles will protect eyes. People with a history of skin complaints may be particularly susceptible to irritation. High dust levels are only likely to arise following harsh abrasion. In general, normal handling and use will not present high risk, follow good hygiene practices, wash hands before, touching eyes, consuming food, drinking or using the toilet.

First aid - Medical attention must be sought following eye contact or prolonged reddening of the skin.

Thermostat / Temperature gauge

Description - Sealed phial and capillary containing liquid.

Known hazards - irritating to skin, eyes and throat. Vapour is harmful. Inflammable -do not extinguish with water.

Precautions - Do not incinerate. Avoid contact with broken/leaking phials. Do not purposely puncture.

First aid - medical attention must be sought following eyes/skin contact, wash with clean water.

Sharp Edges

Caution should be taken when handling the boiler to avoid sharp edges on the boiler.

Boiler installation and commissioning tips

√ The installation must be carried out by a qualified Gas Safety Registered Engineer who will be responsible for observing the current Regulations and the completion of the Benchmark Gas Boiler System Commissioning Checklist, located at the back of this User manual.

Internally installed mains water meters

Please ensure if the property has had a water meter installed inside the property that it does not include a non-return valve, should you find that it does include a non-return valve then provision of a WRAS approved mini expansion vessel must be made.

Biasi optional WRAS approved easy fit 15 mm mini shock arrestor kit BI9999 999 can be obtained through your local Biasi stockist.

Installing the boiler...

√ Do not forget to remove the transit caps and plugs from the boiler connections these are fitted to every boiler.
√ Keep the boiler clear of dust during installation and in particular do not allow any dust or debris to enter the top of the boiler where the flue connection is made. It is recommended that you put a dust sheet over the top of the boiler until you are ready to make the flue connection.
√ Remember to release the auto air purge before filling the boiler. See the instructions to identify the location of this device.
√ This boiler allows to control the flow temperature of the central heating system at very low levels. In case of underfloor heating system a temperature limiting device (e.g. a safety thermostat) is recommended to stop the boiler in case that the water temperature exceeds the design temperature.
√ You are strongly advised to the British Standard BS 7593-2006 Code of practice, flush out the system both cold and hot in order to remove system and installation debris.
√ It is also sensible to initially fire and commission the boiler before connecting any external controls such as a room thermostat. By following this procedure if you have a subsequent problem this method if you have a subsequent problem following the addition of an external control you can eliminate the boiler from your fault analysis.
√ If the boiler is fitted with a digital programmer, when setting the times for automatic operation, remember that for every "ON" time there must be an "OFF" time to follow and that on every occasion you enter a time you must also indicate which days that you want the boiler to follow the timed settings.
√ Some products incorporate an anti cycling time delay. It is normal when first switching the boiler on for the boiler to operate on heating for a few seconds then switch off. After 3 - 4 minutes has elapsed the boiler will then re ignite and operate perfectly normally. The ignition delay cycle does not prevent normal operation of the boiler to provide d.h.w.
√ If you are in any doubts as to the installation or operation of the boiler please read the instruction manuals thoroughly and then if necessary contact Biasi UK for advice and assistance.
√ Guarantee conditions. The guarantee registration form must be returned within 30 of purchase, failure to comply will invalidate the guarantee.

Please remember that if you are in any doubt about the installation of this product you can contact our Technical Help line on tel. [phone].

2 INSTRUCTIONS FOR USE

2.1 Warnings

Biasi UK Ltd support the Benchmark initiative. The Benchmark Checklist is located at the back of this manual and should be completed by the Installing/Commissioning Engineer and handed over to the User for future reference by other visiting Engineers.

Also included is the Service Interval Record card that should be completed by the Service Engineer following the annual service maintenance of the boiler and system.

All Gas Safe Registered Installers carry a Gas Safe ID card, and have a registration number. Both should be recorded in your Benchmark Checklist. You can check your Installer is registered by calling Gas Safe direct on 0800 408 5500, or go on line at www.GasSafeRegister.co.uk.

In order to guarantee safety and correct operation, it is essential that all the tests are carried out by a competent and responsible service engineer before lighting up the boiler.

The tests are described in the installation instructions in section 7 commissioning.

Ensure that the c.h. circuit is regularly filled with water (even if the boiler is only used for d.h.w. supply).

In order to activate, press keys 14 and 16 together to access the "INFO" menu. The display displays the value "d0" that alternates with the pressure value "13" (1,3 bar). The number indicating the pressure, is displayed without decimal points while the letter indicates the unit of measure (bar) Fig. 2.2.

If the pressure reading on the pressure gauge is below that shown in Fig. 2.2, then the system will require topping up. A filling loop is normally provided by the Installer for this purpose.

If you are in any doubt regarding this procedure you are advised to contact your Installer or an Approved Engineer.

This appliance is provided with a built in anti-freeze system that operates the boiler when the temperature is below 5 °C.

Therefore, when the boiler is not lit or used in cold weather, with consequent risk of freezing do not switch off the boiler at the fused spur isolation switch or close the gas inlet cock.

When you do not expect to use the boiler for a long period and the boiler is not to be used for frost protection then follow the instructions given in section "Extinguishing" to page 17.

2.2 Refilling procedure

- Isolate the boiler from the electrical supply at the fused spur. Reconnect the filling loop as demonstrated in Fig. 2.1.

Control valve Double check valve Temporary connection Supply pipe (cold water inlet) C.h. return pipe Control valve

- Open the valves of the filling loop and watch the display until it reaches normal filling pressure as shown in Fig. 2.2.

00 13

Fig. 2.2

If you experience any difficulty with the operation of the boiler, switch off the boiler immediately at the fused spur isolation switch and contact your Installer or an approved Service Engineer.

Air introduced into the boiler during this filling process will vent through the automatic air purger fitted to the boiler. You may also find it necessary to vent air from your radiator circuit using your radiator key, however be aware that excessive venting will cause the pressure in the system to drop.

Always ensure that the pressure gauge is set at the required pressure.

2.3 Ignition

- Check that the valves located in the lower part of the boiler are open Fig. 2.3.

- If necessary, empty the hydraulic circuits see section "Emptying the d.h.w. system" to page 77 and section "Emptying the c.h. system" to page 78.

3 USEFUL ADVICE

3.1 Central Heating

For reasonably economical service install a room thermostat. Never shut off the radiator in the area where the room thermostat is installed.

If a radiator (or a convector) does not heat up, check that no air is present in it and that its valve is open. If the ambient temperature is too high, do not alter the radiator valves.

Reduce the central heating temperature in stead by means of the room thermostat or by acting on the 15 and 16 heating adjustment keys (Fig. 3.1).

12 13 14 15 16

Fig. 3.1

3.2 Frost protection

The anti-freeze system and any additional protections protect the boiler from possible damage due to frost.

This system does not guarantee protection of the entire hydraulic system.

If the external temperature can reach values lower than 0^ C, it is recommended that the entire system is activated adjusting the room thermostat at a low temperature.

The anti-freeze function is also activated with the boiler in stand-by (Fig. 3.2).

Two dark hexagonal shapes on a white background, no text or symbols present

Fig. 3.2

Therefore, when the boiler is not lit and used in cold weather, with consequent risk of freezing do not switch off the boiler at the fused spur isolation switch or close the gas inlet cock.

If the boiler is deactivated, have a qualified technician empty the boiler (heating and domestic hot water circuit), the c.h. system and the d.h.w. system.

3.3 Condensate drain

The condensate drain must not be modified or blocked. Blockage of the condensate drain, caused by debris or freezing, can cause automatic shutdown of the boiler. If freezing is suspected and the pipe run is accessible an attempt may be made to free the obstruction by pouring hot water over the exposed pipe an cleaning any blockage from the end of the pipe.

If this fails to remedy the problem the assistance of a Gas Safe registered installer or in IE a competent person should be sought.

3.4 Periodic maintenance

For efficient and continuous operation of the boiler, it is advisable to arrange maintenance and cleaning by an Authorised Service Centre Engineer, at least once a year.

During the service, the most important components of the boiler will be inspected and cleaned. This service can be part of a maintenance contract. In particular, you are advised to have the following checks carried out:

• domestic hot water heat exchanger;
• condensing heat exchanger;
- burner;
- exhaust fume duct and flue;
- pressurisation of the expansion tank;
- filling up of the central heating circuit;
- bleeding of air from the central heating system;
- general check of the appliance's operation.

USEFUL ADVICE

3.5 External cleaning

Before carrying out any cleaning, disconnect the appliance from the electrical mains, using the fused spur isolation switch fitted adjacent to the appliance.

To clean the external panels, use a cloth soaked in soapy water. Do not use solvents, abrasive powders or sponges.

Do not carry out cleaning of the appliance and/or its parts with readily flammable substances (for example petrol, alcohols, naphtha, etc.).

3.6 Operational faults

If the boiler does not function and a code that alternates between the letter Er and the writing RESET (see "LCD general features" to page 9) appear on the LCD display, it in - indicates that the safety lock-out has stopped the boiler. The display background flashes (Fig. 3.3).

E1 RESET 01 RESET

Fig. 3.3

For the first lighting up and following maintenance procedures for the gas supply, it may be necessary to repeat the resetting operation several times so as to remove the air present in the pipe work.

Safety lock-out may occureven in case of a blockage of the condensate drainage (e.g. plugged drain pipe). It is advisable to check

the condensate drainage pipe and traps for cleanness.

Press the reset key on the boiler control panel 14 (Fig. 3.1) to reset its functioning.

In this case and in case of persistent lock-out call a competent and responsible Service Engineer.

Other operational faults signalled on the LCD display

If the LCD display displays a code that alternates between the letter Er and the symbol, the boiler has an anomaly that cannot be reset.

The display background flashes (Fig. 3.4).

E 06

Fig. 3.4

Another possible signal occurs when the d.h.w. exchanger cannot exchange all of the power supplied by the boiler.

E.g.: d.h.w. exchanger clogged with lime scale. This happens only when the boiler has a request for d.h.w..

Code 01 appears on the LCD display that alternates with the letter Li. The display background flashes (Fig. 3.5).

L 0 1

Fig. 3.5

In order to reset good functioning of the boiler, call a competent and responsible Service Engineer.

Noise due to air bubbles are heard during operation

You should check that the pressure on the pressure gauge is not below the correct setting.

If required, top up the system correctly, as described in the section "Refilling procedure" to page 12 of this manual. Bleed any air present in the radiators, if necessary.

The pressure has gone down

It is necessary to top up the appliance with water again, so as to raise the pressure to an adequate level as described in the section "Refilling procedure" to page 12 of this manual. If topping up with water has to be done very frequently, have the system checked for leaks.

Water comes out of the pressure relief valve

Check on the pressure gauge that the pressure in the central heating circuit is not close to 3 bars. In this case, temperature rise in the circuit can cause the pressure relief valve to open. So that this does not happen and to decrease the pressure to a normal value, it

is advisable to vent some of the water in the appliance through the bleed valves present in the radiators.

Reduced domestic hot water temperature

The likely causes may be impurities caught in the domestic hot water flow switch filter or limescale deposited in the domestic hot water heat exchanger. It is advisable to have the appliance cleaned out by an Authorised Service Centre Engineer.

Water should occasionally leak from the boiler

Shut off the valves positioned under the boiler to page 17 and call an Authorised Service Centre Engineer.

In this case or in case of problems other than those mentioned here, switch off the boiler, as described in section "Extinguishing" to page 17 and call a competent and responsible Service Engineer.

3.7 Displaying in INFO mode

The INFO mode allows the display of some information on the boiler functioning status. In case of malfunctioning of the boiler, it may be useful to communicate such information to the Authorised Service Centre Engineer so that the causes can be understood.

In order to access the INFO mode, press keys 14 and 16 (Fig. 3.6) at the same time until the letter di appears on the display that alternates with a code (Fig. 3.7).

3.8 Remote anomaly code

If the boiler is connected to remote (optional), a code that indicates a boiler anomaly is displayed in the centre of the display.
The anomaly in progress is indicated by a numeric code followed by the letter E.
The table summarises the possible codes displayed on the remote.

Anomaly Code
Lack of burner ignition	01E
Safety thermostat lockout	02E
General lockout	03E
Faulty primary circuit(no water or absence flow)	04E

3.9 Flue probe

The flue probe 19 and safety thermal fuse 20 indicated in Fig. 3.8 are a safety device. The flue probe 19 intervenes when the flue temperature exceeds 110^ C placing the boiler in safety block switching it off.

To reset normal boiler functioning, just press the 14 (Fig. 3.6) key.

If flue probe 19 does not intervene and, therefore does not send the boiler into security lockout, thermofusible 20 enters into function as a further safety measure.

This component sends the boiler into security lockout when the flue temperature reaches 167^ C.

To restore the normal operation of the boiler, contact the Authorized Service Centre.

The boiler load loss has already been removed.

Flow rate with closed thermostatic valves

The boiler is equipped with an automatic by-pass, which protects the condensing primary exchanger.

In case of excessive reduction or total stopping of water circulation in the heating plant due to the closing of thermostatic valves or circuit elements valves, by-pass ensures a

minimum water circulation inside the condensing primary exchanger.

The by-pass is calibrated to a differential pressure of about 0.3-0.4 bar.

4.4 Expansion vessel

Note: this boiler is designed for operation only in a sealed central heating system.

The height difference between the pressure relief valve and the highest point in the system may be 10 m at most.

For greater differences, increase the pre-load pressure in the expansion vessel and the system, when cold, by 0.1 bar for each additional 1 m.

5 GENERAL REQUIREMENTS

benchmark COLLECTIVE MARK THE MARK OF QUALITY FOR THE INSTALLATION COMMISSIONING AND SERVICING OF DOMESTIC HEATING AND HOT WATER SYSTEMS

Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure that customers are provided with the correct equipment for their needs, that it is installed, commissioned and serviced in accordance with the manufacturer's instructions by competent persons and that it meets the requirements of the appropriate Building Regulations. The Benchmark Checklist can be used to demonstrate compliance with Building Regulations and should be provided to the customer for future reference.

Installers are required to carry out installation, commissioning and servicing work in accordance with the Benchmark Code of Practice which is available from the Heating and Hotwater Industry Council who manage and promote the Scheme. Visit www.centralheating.co.uk for more information.

Our Company supports the Benchmark initiative. The Benchmark Checklist is located at the back of this manual and should be completed by the Installing/Commissioning Gas Safety Registered Engineer and handed over to the User for future reference by other visiting Engineers. Also included is the Service Interval Record card that should be completed by the Service Engineer following the annual service maintenance of the boiler and system.

For Ireland (IE), it is necessary to complete a “Declaration of Conformity” to indicate compliance to I.S.813.2002.

This appliance must be installed by a competent person in accordance with the Gas Safe (installation & Use) Regulations.

5.1 Related documents

The installation of this appliance must be in accordance with the relevant requirements of the current Gas Safe (Installation & Use) Regulations, the Local Building Regulations, the current I.E.E. Wiring Regulations, the Regulations and by-laws of the local water undertaking, and in Scotland, in accordance with the Building Standards (Scotland) Regulation. Health and safety document n° 635 "Electricity at work regs.".

It should also be in accordance with the British Standard Codes of Practice:

In Ireland (IE). The installation must be carried out by a Competent Person and installed in accordance with the current edition of I.S.813.2002 “Domestic Gas Installations” the current Building Regulations and reference should be made to the current ETCI rules for electrical installations.

5.2 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 applicable in Scotland, with respect to the installation of the combined appliance in a room containing a bath or shower.

For Ireland (IE), reference should be made to the current edition of I.S.813.2002 and the current ETCI rules for electrical installations.

Where a room-sealed appliance is installed in a room containing a bath or shower, any electrical switch or appliance control, utilising mains electricity should be so situated that it cannot be

touched by a person using the bath or shower.

The location must permit the provision of an adequate flue and termination.

For unusual locations special procedures may be necessary and BS 6798 gives detailed guidance on this aspect.

A compartment used to enclose the appliance must be designed specifically for this purpose. This appliance is not suitable for external installation.

5.3 Flue system

The provision for satisfactory flue termination must be made as described in BS 5440 part 1.

For Ireland (IE), refer to I.S.813.2002.

The appliance must be installed so that the flue terminal is exposed to external air.

It must not be installed so that the terminal discharges into an other room or space as an outhouse or lean-to. It is important that the position of the terminal allows a free passage of air across at all times.

The terminal should be located with due regard for the damage or discoloration that might occur to building products in the vicinity.

In cold and/or humid weather water vapour may condense on leaving the flue terminal; the effect of such "steaming" must be considered.

Pluming may easily occur at the terminal. Where possible, terminal position which could cause a nuisance should be avoided.

The minimum acceptable spacing from the terminal to obstructions and ventilation openings are specified in Fig. 5.1.

** Consideration should be given to adding protection against condensate to the adjacent structure
*** Wall terminals with horizontal discharge less than 2.5 m from a car parking space and less than 2,1 m above the ground.

Wall terminals less than 2,1 m above the ground with horizontal discharge of the flue products across a public footway, or a frequently used private access route, or a patio (hard surface area).

5.4 Gas supply

The Gas meter is connected to the service pipe by the local gas region or a local gas region contractor.

If the gas supply for the boiler serves other appliances ensure that an adequate supply is available both to the boiler and the other appliance when they are in use at the same time.

Pipework must be of adequate size. Pipes of a smaller size than the boiler inlet connection should not be used.

Installation pipes should be fitted in accordance with BS 6891 and the complete installation should be tested for tightness.

For Ireland (IE), refer to I.S.813.2002.

5.5 Air supply

The room in which the boiler is installed does not require a purpose provided air vent.

5.6 Ventilation

If installed in a cupboard or compartment, it is not necessary to provide additional ventilation for cooling for this particular product.

However consideration must be given to clearance requirements for maintenance (section "Precautions for installation" to

page 44) and under no circumstances must stored articles be allowed to come into contact with the boiler or flue pipe.

5.7 Condensate drain

Ensure that the condensate discharge complies with the national or local regulations in force.

The condensate pipe must be fitted in accordance with Building Regulations.

Drain pipe material should be resistant to acid as the condensate is slightly acid with a pH less than 6.5.

The boiler includes a trap (26 on page 22) that prevents the combustion products entering the drain.

The boilers incorporate a condensate trap with a 75 mm seal to comply with BS 6798:2008.

The schematic diagrams of possible connections are given in Fig. 5.2 and Fig. 5.3.

The length of the condensate pipe should be kept to a minimum, any external pipe should not be more than 3 m in 32 mm pipe and insulated to prevent freezing.

To avoid condensate being trapped:

• the drain pipe should be run with a fall of at least 2.5^ (45 mm/m) away from the boiler;
• the number of bends and joints should be kept at minimum;
• the drain pipe should be adequately fixed to prevent pipe sagging.

If a part of the drainpipe runs externally this part should be kept as short as possible and protected to reduce the risk of freezing.

5.8 Water circulation (c.h.)

Detailed recommendations are given in BS 6798, BSEN 12828: 2003, BSEN 12831: 2003 & BSEN 14446: 2004; the following notes are given for general guidance.

For Ireland (IE), refer to I.S.813.2002.

Pipework

Copper tubing to BSEN 1057 is recommended for water pipes. Jointing should be either with capillary soldered or with compression fittings.

Where possible pipes should have a gradient to ensure air is carried naturally to air release points and water flows naturally to drain taps.

The appliance has a built-in automatic air release valve, it should be ensured as far as possible that the appliance heat exchanger is not a natural collecting point for air.

Except where providing useful heat, pipes should be insulated to prevent heat loss and to avoid freezing.

Particular attention should be paid to pipes passing through ventilated spaces in roofs and under floors.

By-pass

The appliance includes an automatic bypass valve which protects the main heat exchanger in case of reduced or interrupted water circulation through the heating system due to the closing of thermostatic valves or cock-type valves within the system.

The by-pass is calibrated to assure a minimum flow of 200-300 lts/hr through the main heat exchanger.

If you are installing a system that includes thermostatic radiator valves (TRV) and/or small bore (8-10 mm) it may be necessary to fit an external by-pass to facilitate correct operation of the boiler.

The fitting of an external bypass helps to prevent and limit system noise.

Air release points

These must be fitted a tall high points where air will natural collect and must be sited to facilitate complete filling of the system.

Expansion vessel

The appliance has an integral sealed expansion vessel to accommodate the increase of water volume when the system is heated. Refer to Fig. 4.5 on page 25 for its technical data.

If the heating circuit has an unusually high water content, calculate the total expansion and add an additional sealed expansion vessel with adequate capacity.

Mains water feed: central heating

There must be no direct connection to the mains water supply even through a non return valve, without the approval of the Local Water Authority.

Mains water feed: hot water supply

The domestic section of the boiler is designed to withstand an internal domestic water pressure of 10 bar. Where it is likely that the mains domestic water pressure may exceed 5 bar, it is possible due to internal “water hammer” effects that the pressure within the domestic system can increase to a level in excess of the 10 bar limit.

In these circumstances it is therefore recommended that a 3 bar pressure reducing valve be fitted to the incoming mains water supply and a mini expansion vessel installed on the domestic circuit.

These devices will protect the boiler and the domestic system from damage due to excessive domestic water pressure.

Filling

A method for initially filling the system and replacing water lost during servicing must be provided and it must comply with local water authority regulations.

The correct method is shown in Fig. 5.4. The temporary connection must be removed immediately after filling.

Control valve Double check valve Temporary connection Supplypipe (c old water inlet) C.h. return pipe Control valve

Fig. 5.4

The installer should ensure that no leaks exist either inside the boiler or on the system as frequent filling of the system could cause premature scaling of the heat exchanger.

5.9 Domestic water

The domestic water installation must be in accordance with the relevant recommendations of BS 5546. Copper tubing to BS EN 1057 is recommended for water carrying pipework and must be use for pipework carrying potable water.

For Ireland (IE), refer to I.S.813.2002.

5.10 Water treatment

C.h. circuit

Where a new boiler is fitted to a new system with either plastic or copper pipes, it is important the system is fully flushed, on completion, to ensure flux residues, swarfs, oils and other installation debris is removed. Where a new boiler is fitted to an existing system, it is important the debris from the existing system is fully removed in order to ensure the efficiency of the new appliance is maintained.

Details on flushing procedure are given in the section "Initial filling of the system" to page 58 of this manual.

D.h.w. circuit (scale protection)

In areas where the water is 'hard' (i.e. more than 200 ppm total hardness as defined by

BS 7593: 2006 Table 2) it is recommended that a proprietary scale-reducing device is fitted into the boiler cold supply, within the requirements of the local water company.

5.11 Electrical supply

Warning, this appliance must be earthed.

External wiring to the appliance must be carried out by a competent person and be in accordance with the current I.E.E. Regulations and any local regulations which apply.

Reference should be made to the current ETCI rules for electrical installations.

For Ireland (IE), refer to I.S.813.2002.

The boiler is supplied for connection to a 230 V\~ 50 Hz supply. The supply must be fused at 3A.

The method of connection to the electricity supply must facilitate complete electrical isolation of the appliance by the use of a fused spur isolation switch. Its installation permits a complete switching off in the conditions of the overvoltage category III. Alternatively it can be used a 3A fused three pin plug and unswitched shuttered socket outlet both complying with BS 1363.

The point of connection to the electricity supply must be readily accessible and adjacent to the appliance, except where the appliance is installed in a bathroom, this must then be sited outside the bathroom.

INSTALLATION

6 INSTALLATION

6.1 Warnings

The use of gas appliances is subject to statutory control; it is essential to observe the current regulations and laws in force (see also chapter 5).

The appliance must discharge combustion products directly outside or into a suitable ex-haust duct designed for this purpose. Combustion products must be discharged using original flue kits only, since they are integral parts of the boiler.

The appliance is not suitable for receiving condensate coming from the combustion products evacuation system.

Combustion air must avoid contents of chlorine, ammonia, or alkali agents. Installation of a boiler near a swimming pool, a washing machine, or a laundry does expose combustion air to these aggressive contents".

Before installing the boiler on an existing c.h. system, flush it out thoroughly before fitting the boiler.

This procedure is to remove the presence of any residues or impurities that could compromise good functioning of the boiler.

After washing it is necessary to treat the plant.

The conventional warranty does not cover any problems deriving from failure to comply with such provisions.

For Propane, the appliance must also conform with the requirements of the distributors and comply with current Regulations and laws in force.

The safety relief valve and the condensate

drain must be connected to a suitable drain, or discharge in a safe manner.

The electrical wiring must conform with current Regulations, in particular:

• the boiler must be earthed using the correct bonding clamp.
• a fused spur isolation switch, must be installed near to the boiler that allows complete disconnection in overvoltage III category conditions.

Refer to section "Electric connection" to page 52 in this chapter for the electrical connections.

In no circumstances will the manufacturer be held responsible if the warnings and instructions contained in this manual have not been complied with.

6.2 Precautions for installation

The following prescriptions must be respected for installation:

• The boiler must be fixed to a strong wall.
• The dimensions for the exhaust fume duct (detailed in section "Choice of flu" to page 48) and the correct procedures for installing the duct, depicted in the instruction leaflet included with the flue kit, must be complied with during installation.
• To allow maintenance procedures it is necessary to leave the minimum gaps indicated in Fig. 6.1.

INSTALLATION

250 2525 200 All measures are in mm

Fig. 6.1

• When installing the boiler in a cupboard, cover or alcove allow at least 5 mm permanent clearance from the front face of the boiler. Also ensure sufficient clearance to allow free access for servicing and the lowering of the front control panel.
• If the boiler is installed outside, cover the appliance to protect it against the elements and add some special anti-freeze (neutralised) to the c.h. system.
• Before installing the boiler on an existing c.h. system, flush it out thoroughly before fitting the boiler, so as to remove muddy deposits.

It is advisable to equip the system with a sediment filter, or use a water-treatment product in the circulating water.

The latter option in particular, not only cleans out the system, but also has an anti-corrosive effect by promoting formation of a protective skin on metal surfaces and neu-

tralising gases present in the water.

We recommend the use of a suitable universal inhibitor to protect the c.h. system from corrosion.

6.3 Installing the bracket Precautions

Before mounting the bracket, check that the dimensions for fitting the exhaust fume duct are complied with (refer to the leaflet included with the flue kit, packed separately).

Utilise the paper template supplied with the boiler to determine the fixing position for the bracket and boiler. Securely mount the bracket to the wall using appropriate fixings suitable for the type of wall construction and capable of supporting the total (wet) load. Refer to the weight given in the technical data tables specific for each model.

6.7 Fitting the flue system

For a correct installation of the flue pipe, refer to the sheet provided together with the pre-selected kit.

The horizontal routes of the flue pipes must incline about 1.5 degrees (25 mm per meter); therefore the terminal must be higher than the intake at the boiler.

The single coaxial pipe with the terminal must be fitted horizontal as the drainpipe is already angled with the correct incline.

6.15 Example of hydraulic plants with hydraulic separator (optional)

The hydraulic separator creates a reduced load loss zone that renders the primary circuit and secondary circuit hydraulically independent.

In this case the flow rate that passes through the circuits depends exclusively on the features of the pumps flow rate.

Therefore, by means of a hydraulic separator, the secondary circuit's flow rate is put into circulation only when the relative pump is on.

When the pump of the secondary is off, there is no circulation in the corresponding circuit and therefore, the entire flow rate pushed by the primary is by-passed through the separator.

Thus, with the hydraulic separator, it is possible to have a constant flow rate production circuit and a variable flow rate distribution

circuit.

7.7 Checking the gas supply pressure

This boiler has been factory tested to the highest quality control standards and set for the minimum and maximum gas working pressures, connected to a 1 m flue and a gas supply pressure of 20 mbar.

Any variation in gas supply pressure or flue length may result in the customer experiencing a harmonic noise from the boiler. In these circumstances, it may be necessary to reset the burner gas pressures in accordance with section 11 Gas Valve of the Service Manual.

It should be noted that a Flue Gas Analyser is required for this procedure.

7.8 Checking the inlet pressure

• Remove the boiler body's front panel, see section "Dismantling the external panels" to page 76.
• When the boiler is switched off (out of order), check the supply pressure by using the 30 point in Fig. 7.9 and compare the value read with that reported on the Gas supply pressure table in the "Technical Data" section (pag. 26 Advance Plus 25C ERP, pag. 30 Advance Plus 30C ERP and pag. 34 Advance Plus 35C ERP).
• Close well the pressure point 30 in Fig. 7.9.
