and in the Republic of Ireland in accordance with the following codes of practice:

I.S. 813 Domestic Gas Installations

Avoid installing the boiler where the air inlet can be polluted by chemical products such as chlorine (swimming pool area), or ammonia (hair dresser), or alkalin products (launderette).

Flue

Detailed information on fl ue assembly can be found in the "Connecting the Flue" section.

The boiler must be installed so that the flue terminal is exposed to the free passage of external air at all times and must not be installed in a place likely to cause nuisance. It must not be allowed to discharge into another room or space such as an outhouse or closed lean-to.

Condensing boilers have a tendency to form a plume of water vapour from the fl ue terminal due to the low temperature of the fl ue gasses. The terminal should therefore be located with due regard for the damage or discolouration that may occur to building within the vicinity and consideration must also be given to adjacent boundaries, openable windows should also be taken into consideration when siting the fl ue.

The minimum acceptable clearances are shown below:

• A Directly below an opening, window, etc 300 mm
• B Horizontally to an opening, window, etc 300 mm
• C Below gutters, soils pipes or drain pipes 75 mm
• D Below eaves 200 mm
• E From vertical drain pipe or soil pipe 75 mm
• F From internal or external corner 300 mm
• G Above ground, roof or balcony level 300 mm
• H From a surface facing the terminal 600 mm
• I From a terminal facing a terminal 1200 mm
• J Vertically from a terminal on the same wall 1500 mm
• K Horizontally from an terminal on the same wall 300 mm
• L Fixed by vertical fl ue terminal

NOTE: THE FLUE MUST NOT BE INSTALLED IN A PLACE LIKELY TO CAUSE A NUISANCE AND POSITIONED TO ENSURE THAT PRODUCTS OF COMBUSTION DO NOT DISCHARGE ACROSS A BOUNDARY

It may be necessary to protect the terminal with a guard, if this is the case it will be necessary to purchase a stainless steel terminal guard. Reference should be made to the Building Regulations for guidance.

Ventilation

The room in which the boiler is installed does not require specific ventilation. If the boiler is installed in a cupboard or compartment ventilation is not required for cooling purposes.

Gas Supply

The gas installation and tightness testing must be in accordance with the requirements of BS6891. Ensure that the pipe size is adequate for demand including other gas appliances on the same supply.

Electrical Supply

The appliance requires an earthed 230V - 50 Hz supply and must be in accordance with current I.E.E. regulations. It must also be possible to be able to completely isolate the appliance electrically. Connection should be via a 3 amp double pole fused isolating switch with contact separation of at least 3mm on both poles. Alternatively, a fused 3 amp, 3 pin plug and unswitched socket may be used, provided it is not used in a room containing a bath or shower. It should only supply the appliance.

Water Supply

The boiler is suitable for sealed systems only. The maximum working pressure for the appliance is 6 bar. All fittings and pipework for the appliance should be of the same standard. If there is a possibility of the incoming mains pressure exceeding 6 bar, particularly at night, then a suitable pressure limiting valve must be fitted.

The boiler is designed to provide hot water on demand to multiple outlets within the property. If there is a requirement for greater demands, for example if the boiler has several bathrooms and cloakrooms, a vented or unvented hot water storage system may be used.

Showers

Any shower valves used with the appliance should be of a thermostatic or pressure balanced type. Refer to the shower manufacturer for performance guidance and suitability.

Flushing and Water Treatment

The boiler is equipped with a stainless steel heat exchanger.

The detailed recommendations for water treatment are given in BS 7593 (Treatment of water in domestic hot water central heating systems); the following notes are given for general guidance.

If the boiler is installed on an existing system, any unsuitable additives must be removed.

Under no circumstances should the boiler be fired before the system has been thoroughly flushed; the flushing procedure must be in line with BS 7593.

We highly recommend the use of a flushing detergent appropriate for the metals used in the circuit.

In hard water areas or where large quantities of water are in the system the treatment of water to prevent premature scaling of the main exchanger is necessary.

The formation of scale heat compromises the efficiency of the thermic exchanger because small areas of scale cause a high increase of the temperature of the metallic walls and therefore add to the thermal stress of the heat exchanger.

Demineralised water is more aggressive so in this situation it is necessary to treat the water with an appropriate corrosion inhibitor.

Any treatment of water by additives in the system for frost protection or for corrosion inhibition has to be absolutely suitable for all metals used in the circuit.

The use of a corrosion inhibitor in the system is recommended to prevent corrosion (sludge) damaging the boiler and system;

If anti-freeze substances are to be used in the system, check carefully that they are compatible with the metals used in the circuit.

ARISTON suggests the use of suitable anti-freeze products, which will prevent rust and incrustation taking place.

Periodically check the pH balance of the water/anti-freeze mixture of the boiler circuit and replace it when the amount measured is out of the range stipulated by the manufacturer (7 < pH < 8).

DO NOT MIX DIFFERENT TYPES OF ANTI-FREEZE

In under-floor systems, the use of plastic pipes without protection against penetration of oxygen through the walls can cause corrosion of the systems metal parts (metal piping, boiler etc), through the formation of oxides and bacterial agents.

To prevent this problem it is necessary to use pipes with an "oxygen proof barrier", in accordance with standards DIN 4726/4729. If pipes of this kind are not used, keep the system separate by installing heat exchangers of those with a specific system water treatment.

Ariston suggests the installation of a magnetic filter on every installation.

IMPORTANT

Failure to carry out the water treatment procedure will invalidate the appliance warranty.

System Controls

The boiler is electrically controlled and is suitable for most modern electronic time and temperature controls. The addition of such external controls can be beneficial to the efficient operation of the system. The boiler connections for external controls are 12V DC and so only controls of 12V DC that have voltage free contacts should be used. (page 25).

ARISTON supply a range of wired and wireless system controls. Contact your supplier for more details.

Location

The boiler can be installed on any suitable internal wall (suitable sound proofing may be required when installing onto a stud partition wall). Provision must be made to allow for the correct routing of the flue and siting of the terminal to allow the safe and efficient removal of the flue products. A compartment or cupboard may be used provided that it has been built or modified for this purpose. It is not necessary to provide permanent ventilation for cooling purposes. Detailed recommendations are given in BS 5440 Part 2. If it is proposed that it is to be installed in a timber framed building then reference should be made to IGEM Document, IGE/UP/7 or advice sought from Gas Safe.

Where a room sealed appliance is installed in a room containing a bath or shower, the appliance and any electrical switch or appliance control, utilising mains electricity should be situated specifically in accordance with current IEE Wiring Regulations.

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

Codensate Discharge

The condensate discharge hose from the boiler must have a continuous fall of 2.5° and must be inserted by at least 50mm into a suitable acid resistant pipe - e.g. plastic waste or

INSTALLATION

overfl ow pipe. The condensate discharge pipe must have a minimum diameter of 22mm, must have a continuous fall and preferably be installed and terminated to prevent freezing. The discharge pipe must be terminated in a suitable position:

i) Connecting into an internal soil stack (at least 450mm above the invert of the stack). A trap giving a water seal of at least 75mm must be incorporated into the pipe run, there also must be an air beak upstream of the trap.
ii) Connecting into the waste system of the building such as a washing machine or sink trap. The connection must be upstream of the washing machine/sink. If the connection is downstream of the waste trap then an additional trap giving a minimum water seal of 75mm and an air break must be incorporated in the pipe run, as above.
iii) Terminating into a gully, below the grid level but above the water level
iv) Into a soakaway

Note: If any condensate pipework is to be installed externally then it should be kept to a minimum and be insulated with a waterproof insulation and have a continuous fall. The total length of external pipe used should not exceed 3 metres.

Some examples of the type of condensate terminations can be found below.

Safety Valve Discharge

The pressure relief valve pipe is made of copper. It should terminate below the boiler safely outside the premises. Care should be taken that it does not terminate over an entrance or window or where a discharge of heated water could endanger occupants or passers by.

WARNING!

DO NOT APPLY HEAT TO THE COPPER SAFETY VALVE OUTLET PIPE WHILST IT IS CONNECTED TO THE 3 BAR SAFETY RELIEF VALVE.

Fill the central heating and DHW system and bleed air from the system as described in the Commissioning instructions (page 27).

The system should be carefully checked for leaks, as frequent refilling could cause premature system corrosion or unnecessary scaling of the heat exchanger. The pipe from the trap should be connected to a drain as described in the relevant regulations.

Pay special attention not to bend the condensate silicone drain pipe is such a way as to interrupt the flow. Please only use drain pipe material compatible with condensate products (refer to BS 6798:2009).

The condensate flow can reach 2 litres/hour because of the acidity of the condensate products (Ph close to 2), take care before operation.

See page 13 for condensate discharge options.

INSTALLATION

Gas connection

Make sure, using the labels on the packaging and the data plate on the appliance itself, that the boiler is in the correct country and that the gas category for which the boiler was designed corresponds to one of the categories available in the country where it will be used.

The gas supply piping must be created and measured out in compliance with specific legal requirements and in accordance with the maximum power of the boiler.

Check that the supplied gas corresponds to the type of gas for which the boiler was designed (see the data plate located on the appliance itself).

It is also important to check that the pressure of the gas (methane or LPG) you will be using to feed the boiler is suitable, because if it is insufficient the power may be reduced, causing inconvenience for the user.

Water connection

The illustration below shows the connections for the water and gas attachments of the boiler. See valves configuration on page 13.

Check that the maximum water mains pressure does not exceed 6 bar; if it does, a pressure reducing valve must be installed.

For the measuring of the pipes and of the heating bodies in the heating system, the residual head value should be calculated as a function of the requested flow rate, in accordance with the values shown in the circulation pump graph.

Underfl oor heating

For appliances with underfloor heating, it is possible but not necessary to fit a safety thermostat onto the underfloor heating outlet. For the electrical connection of the thermostat see the section on "Electrical connections - pages 26".

If the outlet temperature is too high, the boiler will stop both domestic hot water and the heating production and the error code 1 16 "fl oor thermostat contact open" will appear on the display. The boiler will restart when the thermostat is closed during automatic resetting.

If the thermostat cannot be installed, the underfloor heating equipment must be protected by a thermostatic valve, or by a bypass to prevent the floor from reaching too high a temperature.

BEFORE THE DEVICE IS USED, FOR THE FIRST TIME THE TRAP MUST BE FILLED WITH WATER.

The siphon is filled with water during deaeration procedure of the boiler (or heating system) - see p. 32

Ensure that the siphon contains water; if not, it must be refilled. Open the manual air vent (2) on the main exchanger until complete filling. Check again the system pressure on the pressure gauge.

WARNING!

INSUFFICIENT WATER IN THE TRAP CAN TEMPORARILY CAUSE THE FLUE GAS TO BE EXPELLED INTO THE SURROUNDING AMBIENT AIR

Connecting the Flue

Flue System

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

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

The terminal must not discharge into another room or space such as an outhouse or lean-to.

It is important that the position of the terminal allows a free passage of air across it at all times.

The terminal should be located with due regard for the damage or discolouration that might occur on buildings in the vicinity, it must also be located in a place not likely to cause nuisance.

In cold or humid weather water vapour may condense on leaving the flue terminal.

The effect of such "steaming" must be considered.

If the terminal is less than 2 metres above a balcony, above ground or above a flat roof to which people have access, then a suitable stainless steel terminal guard must be fitted.

The minimum acceptable spacing from the terminal to obstructions and ventilation openings are specified in Fig. 1.

Fig. 1

• A Directly below an opening, window, etc 300 mm
• B Horizontally to an opening, window, etc 300 mm
• C Below gutters, soils pipes or drain pipes 75 mm
• D Below eaves 200 mm
• E From vertical drain pipe or soil pipe 75 mm
• F From internal or external corner 300 mm
• G Above ground, roof or balcony level 300 mm
• H From a surface facing the terminal 600 mm
• I From a terminal facing a terminal 1200 mm
• J Vertically from a terminal on the same wall 1500 mm
• K Horizontally from an terminal on the same wall 300 mm
• L Fixed by vertical fl ue terminal

INSTALLATION

Warning

The exhaust gas ducts must not be in contact with or close to infl ammable material and must not pass through building structures or walls made of infl ammable material.

When replacing an old appliance, the fl ue system must be changed.

Important

Ensure that the fl ue is not blocked.

Ensure that the fl ue is supported and assembled in accordance with these instructions.

Installation with extension

Fig. 3

Fitting the Coaxial Flue (∅ 60 / 100 Horizontal)

Contents:

1x Silicone O-Ring (60mm)

1x Elbow (90°)

2x Wall Seals (Internal & External)

1x Flue Pipe including Terminal (1 metre - 60/100)

2x Flue Clamps

4x Screws

2x Seals

Once the boiler has been positioned on the wall, fit the rubber flue seal into the internal flue turret (see diagram opposite),

Insert the elbow into the socket and rotate to the required position. note: It is possible to rotate the elbow 360° on its vertical axis.

Using the flue clamp, seals and screws supplied (Fig 4) secure the elbow to the boiler.

The 1 metre horizontal flue kit (3318073) supplied is suitable for an exact X dimension of 753mm.

Measure the distance from the face of the external wall to the face of the flue elbow (X - Fig 2), this figure must now be subtracted from 753mm, you now have the total amount to be cut from the plain end of the flue.

Note: A Plume management kit is available for 60/100 horizontal termination. Instructions for installation are supplied with the Plume management kit.

Draw a circle around the outer flue and cut the flue to the required length taking care not to cut the inner flue, next cut the inner fl ue ensuring that the length between the inner and outer fl ue is maintained. (Fig 4).

e.g.

$$ X = 5 5 5 \mathrm{mm} $$

753-555 = 198mm (Length to be cut from the plain end of the fl. ue).

Once cut to the required length, ensure that the flue is free from burrs and reassemble the flue. If fitting the flue from inside of the building attach the outer wall seal to the flue terminal and push the flue through the hole, once the wall seal has passed through the hole, pull the flue back until the seal is flush with the wall. Alternatively, the flue can be installed from outside of the building, the outer seal being fitted last.

Should the flue require extending, the flue connections are push fit, however, one flue bracket should be used to secure each metre of flue.

Note: See table for maximum and minimum fl ue runs.

Clamp

Fig. 4

Fitting the 5" Flue

(∅ 80 / 125 Horizontal/vertical)

Once the boiler has been positioned on the wall, it is necessary to insert the ∅80/125 adaptor (Fig. 5) for both horizontal and vertical flue runs into the boiler flue socket (not supplied with flue kit - Part No 3318095).

Push the adaptor onto the boilers fl ue connection, grease the seals then add extensions or elbows as required, secure the adaptor, using the clamp and screws provided.

To fit extensions or elbows it is first necessary to ensure that the lip seal is fitted correctly into the inner flue, once verified, it is simply necessary to push them together, no clamps are necessary to secure the flue components.

Before proceeding to fit the flue, ensure that the maximum flue length has not been exceeded (See the tables) and that all elbows and bends have been taken into consideration, for each additional 90° elbow 1 metre must be subtracted from the total flue length, and for each 45° 0.5 metres must be subtracted from the total flue length (the height of the vertical adaptor and a 45° bend can be seen in Fig.6 and a 90° bend in Fig.7).

Note: DO NOT cut the vertical fl ue kit.

Fig. 6

Fitting the Coaxial Flue (∅ 60 / 100 Vertical)

Note: See table for maximum and minimum fl ue runs.

Contents:

1x Conical Adaptor (60/100mm) 1x Vertical Flue Kit (80/125mm)

The vertical fl ue kit is supplied with a specially designed weather proof terminal fitted, it can be used either with a flat roof or a pitched roof.

The Vertical fl ue kits useable lengths with the pitched roof fl ashings are indicated in Fig. 7.

Before proceeding to fit the flue, ensure that the maximum flue length has not been exceeded (See the tables) and that all elbows and bends have been taken into consideration, for each additional 90° elbow 1 metre must be subtracted from the total flue length, and for each 45° 0.5 metres must be subtracted from the total flue length (the height of the vertical adaptor and a 45° bend can be seen in Fig. 8).

Mark the position of the flue hole in the ceiling and/or roof (see Fig. 7 for distance from wall to the centre of the flue).

Cut a 130mm diameter hole through the ceiling and/or roof and fit the flashing plate to the roof.

DO NOT cut the vertical fl ue kit.

To connect the vertical flue kit directly to the boiler, place the vertical starter kit (Part No. 3318079) (see Fig. 7) onto the exhaust manifold and secure with the clamp, fit the vertical adaptor onto the vertical starter kit (note: there is no need to use a clamp to secure this as it is a push fit connection), the vertical flue kit must then be inserted through the roof flashing, this will ensure that the correct clearance above the roof is provided as the terminal is a fixed height.

Should extensions be required, they are available in 1 metre (Part No. 3318077), 500mm (Part No. 3318078) and they must be connected directly to the vertical starter kit before connecting the adaptor to allow the vertical flue kit to be fitted. In the event that extension pieces need to be shortened, they must only be cut at the male end and it must be ensured that the inner and outer flue remain flush.

When utilising the vertical flue system, action must be taken to ensure that the flue is supported adequately to prevent the weight being transferred to the appliance fl ue connection by using 1 fl ue bracket per extension.

When the flue passes through a ceiling or wooden floor, there must be an air gap of 25mm between any part of the flue system and any combustible material. The use of a ceiling plate will facilitate this. Also when the flue passes from one room to another a fire stop must be fitted to prevent the passage of smoke or flue, irrespective of the structural material through which the flue passes.

Fitting the Twin Pipe (∅80 / 80)

Technical line drawing of a mechanical housing or enclosure with internal components and mounting holes (no text or symbols)

Note: See table for maximum and minimum fl ue runs.

Where it is not possible to terminate the flue within the distance permitted for coaxial flues, the twin flue pipe can be used by fitting a special adaptor to the flue connector and using the aperture for the air intake located on top of the combustion chamber.

Always ensure that the flue is adequately supported, using one fl ue bracket per extension and avoiding low points. (ARISTON supply suitable clamps as Part No. 3318015).

To utilise the air intake it is necessary to:

1) Remove the top of the air intake by cutting it with a suitable knife.
2) Insert the header on the tube or the elbow up until the lower stop (you do not have to use the washer).
3) Insert the elbow/header in the boiler air intake hole and fasten it with screws.

The twin flue pipes can be fitted with or without additional elbows and need no clamps, simply ensure that the lip seal is inserted in the female end of the flue pipe and push the extension piece fully into the previous section of flue pipe or elbow, check that the lip seal is not dislodged when assembling the flue (greasing the seal will aid assembly).

Twin pipe can also be converted back to Coaxial flue to enable vertical termination with a coaxial kit by using the pipe bridge (Twin - Coaxial Adaptor - Part No. 3318089). When running the twin flue pipe vertically.

It is not possible to terminate concentrically horizontally. Termination is only possible with separate air and exhaust terminals.

When siting the twin flue pipe, the air intake and exhaust terminals must terminate on the same wall, the centres of the terminals must be a minimum of 280 mm apart and the air intake must not be sited above the exhaust terminal (refer to Fig. 10). The air intake pipe can be run horizontally, however, the terminal and the final 1 metre of flue must be installed either horizontally or with a slight fall away from the boiler to avoid rain ingress.

It is also strongly recommended that the air intake pipe run be constructed of insulated pipe to prevent condense forming on the outside of the tube.

Ensure the exhaust tube has a minimum fall back to the boiler of 1^/ metre ( 1^=17.5mm/metre )

The maximum permissible flue length for twin flue is dependent on the type of run used (see table on page 23).

For further information relating to flue runs not illustrated, please contact the Technical Department on 0333 240 7777.

Fig. 9

For coaxial systems, the maximum development value, mentioned in the table below also takes into account an elbow. For twin fl ue systems the maximum development value, mentioned in the table includes the exhaust gas/air intake terminal.

Twin fl ue systems outlets should respect the following instructions:

1- Use the same 0 80 mm fl ue pipes for the air intakes and exhaust gas ducts.
2- If you need to insert elbows in the air intake and exhaust gas ducts, you should consider for each one the equivalent length to be included in the calculation of developed length.
3- The exhaust gas duct should jut above the roof by at least 0.5 m.
4- The intake and exhaust gas ducts in Type C13 + C53 must be installed on the same wall, or where the exhaust is vertical and the air intake horizontal, the terminals must be on the same side of the building.

It is important that this is completed in the presence of your customer, they are shown how to use it, and it is signed by them. Please instruct your customer that they must have this manual with them whenever they contact a service engineer or us.

Preliminary electrical system checks to ensure electrical safety must be carried out by a competent person i.e. polarity, earth continuity, resistance to earth and short circuit.

Electricity supply

• Check that the voltage and frequency of the electricity supply correspond to the data shown on the boiler data plate;
• Make sure that the earthing connection is efficient.

Filling the Heating System:

ATTENTION!!

CONNECT THE PIPE OF CONDENSATE DISCHARGE BEFORE REFILLING AND THE DE-AERATION OF THE HEATING CIRCUIT.

Remove the front casing panel and lower the control panel as described on page 14.

Open the central heating flow and return cocks supplied with the connection kit;

Open the manual air vent positioned at the side of the primary exchanger (2). The valve is already connected to a discharge pipe related to the condensate trap.

Close all air release valves on the central heating system;

Gradually open the valves at the filling point (filling loop) until water is heard to flow, do not open fully;

Open each air release tap starting with the lowest point and close them only when clear water free of air is visible;

Continue filling the system until at least 1.5 bar registers on the pressure gauge;

Inspect the system for water tightness and remedy any leaks discovered.

IMPORTANT!

MANUALLY VENT THE HEAT EXCHANGER AT THE MANUAL AIR VENT. FAILURE TO VENT ADEQUATELY MAY DAMAGE THE HEAT EXCHANGER (PAGE 8, LEGEND 2).

Close all hot water draw off taps;

Open the cold water inlet cock supplied with the connection kit; Slowly open each draw off tap and close them only when clear water, free of bubbles, is visible.

Gas Supply:

Inspect the entire installation including the gas meter and test for tightness. The entire installation should be in accordance with the relevant standards. In GB this is BS 6891 and in IE this is the current edition of I.S.813.

The connection on the appliance is a 15mm (22mm on 35Kw) nut and olive located at the rear of the gas service cock.

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

Pipe work must be of an adequate size. The final pipe size must not be smaller than the appliance inlet size.

Open the gas cock (supplied with the connection kit) to the appliance and check the gas connection on the appliance for leaks.

Water Treatment:

The boiler is equipped with a stainless steel heat exchanger.

The detailed recommendations for water treatment are given in BS 7593 (Treatment of water in domestic hot water central heating systems); the following notes are given for general guidance;

If the boiler is installed on an existing system, any unsuitable additives must be removed;

Under no circumstances should the boiler be fired before the system has been thoroughly flushed; the flushing procedure must be in line with BS7593.

Firstly fill the central heating system with the power off, and flush through cold, fill the central heating system again, adding a flushing detergent, run the boiler on central heating until it reaches its operating temperature and flush the system, refill the system with a suitable corrosion inhibitor,

NOTE: FAILURE TO CARRY OUT THE FLUSHING PROCEDURE WILL RESULT IN THE WARRANTY BECOMING VOID.

AUTO function

This is a function which enables the boiler to automatically adapt its operation routine (the temperature of the heating elements) in line with the outdoor conditions, in order to achieve and maintain the requested room temperature conditions.

Depending on the peripheral units connected and the number of zones controlled, the boiler adjusts its flow temperature automatically.

The various corresponding parameters should therefore be set (see adjustments menu).

To activate the function, press the Auto button.

Example 1:

Single zone system (high-temperature) with on/off room Thermostat:

In this case the following parameters must be set:

4 21 - Activation of temperature adjustment using sensors - Select 1 = Basic temperature adjustment
2 44 - Boost Time (optional)

The wait time for the flow temperature increase in steps of 4^ C may be set. The value varies according to the type of system and installation.

If the Boost Time value = 00 the function is not activated.

Example 2:

Single zone system (high-temperature) with on/off room Thermostat + outdoor sensor:

In this case the following parameters must be set:

4 21 - Activation of temperature adjustment using sensors - Select 3 = outdoor sensor only
4 22 - Temperature adjustment curve selection

- Select the relevant curve according to the type of system, installation, heat insulation used in the building, etc.

4 23 - Perform a parallel curve shift if necessary, increasing or decreasing the set-point temperature (this may also be modified by the user, using the heating temperature adjustment knob, which, with the Auto function activated, is used to shift the curve in a parallel manner).

Example 3:

Single zone system (high-temperature) with Sensys controller + outdoor sensor

In this case the following parameters must be set:

4 21 - Activation of temperature adjustment using sensors - select 4 = outdoor sensor + room sensor
4 22 - Temperature adjustment curve selection

- Select the relevant curve according to the type of system, installation, heat insulation used in the building, etc

4 23 - Perform a parallel curve shift if necessary, increasing or decreasing the set-point temperature. (This may also be changed by the user by the buttons 8 which, with the Auto function activated, is used to shift the curve in a parallel manner.)
4 24 - Influence of room sensor

- used to adjust the influence the room temperature has on the calculation of the set-point flow temperature (20 = maximum, 0 = minimum).

Note: See page 38 for details on accessing menus.

Appliance shut-off conditions

The boiler is protected from malfunctions by means of internal checks performed by the electronic P.C.B., which stops the boiler from operating if necessary. In the event of the boiler being shut off in this manner, a code appears on the control panel display which refers to the type of shut-off and the reason behind it.

Two types of shut-off may occur:

Safety shut-off

This type of error is “volatile”, which means that the boiler starts up again automatically as soon as the problem which caused the shut-off is removed.

The display shows the code and the error description.

"Fault 110 - Send Probe Damaged"

In fact, soon as the cause of the shut-off disappears, the boiler starts up again and continues to operate normally.

If the boiler still indicates a safety shut-off, switch it off. Make sure the external electric switch is in the OFF position, shut off the gas valve and contact a qualified technician.

Safety shut-off due to insufficient water pressure

If the re-balancing request is performed on a frequent basis, switch the boiler off, bring the external electric switch to the OFF position, shut off the gas valve and contact a qualified technician to check for any leaks of water.

Operation shutdown

This type of error is “non-volatile”, which means that it is not removed automatically.

The display shows the code and the error description.

To restore normal operation press the RESET button on the control panel.

The display shows "Reset in progress" and then "Fault solved". If the problem manifests itself again after several attempts to reset the appliance, contact a qualified technician.

Important

If this shutdown occurs frequently, contact an authorised Technical Service Centre for assistance. For safety reasons, the boiler will permit a maximum of 5 resets in 15 minutes (5 presses of the RESET button); at the 6th attempt within this 15-minute period the boiler will shut down and may only be operated again after the electricity supply has been disconnected. If the shutdown is occasional or an isolated event, this is not a problem.

The first figure of the error code (e.g. 101) indicates within which operational assembly the error occurred.

1 - Primary Circuit
2 - Domestic Hot Water Circuit
3 - Internal Electronic Part
4 - External Electronic Part
5 - Ignition and Detection

Anti-frost Device

The anti-frost function acts on the central heating flow temperature probe, independently from other regulations, when the electrical supply is turned on.

If the primary circuit temperature falls below 8^ the pump will run for 2 minutes.

After the two minutes of circulation (fixed) the boiler will check the following:

a) if the central heating flow temperature is >8^ , the pump stops;
b) if the central heating flow temperature is between 4 and 8°C, the pump will run for another two minutes;
c) if the central heating flow temperature is < 4^ , the burner will fire (heating position) at minimum power until the temperature reaches 33^ , the burner will go out and the pump will continue to run for two minutes.

The anti-frost device activates only when (with the boiler operating correctly):

• the system pressure is correct;
• the boiler is electrically powered;
• there is a supply of gas.

Important

Maintenance is an essential part of the safe and efficient operation of the boiler and ensures its durability. It should be performed according to the instructions given in current legislation. Perform combustion analysis regularly in order to check the operating efficiency of the boiler and to make sure any polluting substances released are within the boundaries set by current legislation.

Before beginning maintenance work:

- Disconnect the appliance from the electricity supply by turning the external bipolar switch to the "OFF" position;

- Close the gas valve and the central heating and domestic hot water system valves.

After the work has been completed the initial settings will be restored.

General comments

It is recommended that the following inspections be carried out on the boiler at least once a year:

1. Check the seals in the water part and, if necessary, replace the gaskets and restore the seal to perfect working order.
2. Check the seals in the gas part and, if necessary, replace the gaskets and restore the seal to perfect working order.
3. Visually check the overall condition of the boiler.
4. Visually check and, if necessary, disassemble and clean the burner.
5. Following the inspection detailed in point "3", disassemble and clean the combustion chamber, if necessary.
6. Following the inspection detailed in point "4", disassemble and clean the burner, if necessary.
7. Cleaning the primary heat exchanger
8. Make sure the following heating safety devices are operating correctly:

- temperature limit safety device.

1. Make sure that the following gas part safety devices are operating correctly:
2. absence of gas or flame safety device (ionisation).
3. Check the efficiency of the domestic hot water production process (test the flow rate and temperature).
4. Perform a general inspection of the boiler operation.
5. Remove oxide from the detection electrode using an emery cloth.
6. These checks are not exhaustive. Further mechanical, electrical and combustion maintenance checks may be required.

WARNING!!

THE AUTOMATIC CALIBRATION MUST BE DONE IN CASE OF:

• REPLACEMENT OF: FAN, GAS VALVE, AIR/GAS MIXER, BURNER, ELECTRODE.
• REPLACEMENT OF P.C.B.
• GAS CHANGEOVER
• ANY MODIFICATION TO THE FOLLOWING PARAMETERS

220 - SOFT IGNITION

231 - MAX CH ADJUSTABLE
232 - MAX DHW PERCENTAGE
233 - MIN PERCENTAGE
234 - MAX CH PERCENTAGE

Operational test

After having carried out the maintenance operations, fill the heating circuit at a pressure of approximately 1.5 bar and release the air from the system.

Fill the domestic hot water system at the same time.

• Begin operating the boiler.
• If necessary, release the air from the heating system again.
• Check the settings and make sure all the command, adjustment and monitoring parts are working correctly.
• Check the flue system is sealed and operating correctly.

Draining procedures

The heating system must be drained using the following procedure:

• Switch off the boiler, make sure the external bipolar switch is in the OFF position and shut off the gas valve;
• Loosen the automatic air relief valve;
• Open the system drain off cock and collect the escaping water in a container;
• Empty the water from the lowest points of the system (where applicable).

If the system is to be left inactive in areas where the room temperature may fall below 0^ C during winter, we recommend that anti-freeze liquid is added to the water in the heating system in order to avoid the need for repeated draining; when this liquid is used make sure it is compatible with the stainless steel used for the bodywork of the boiler.

We recommend the use of anti-freeze products which contain PROPYLENE GLYCOLS as these inhibit corrosion and that they are used in conjunction with the anti-scaling and anti-corrosion function, in the quantities suggested by the manufacturer, at the minimum temperature.

Regularly check the pH level of the water/anti-freeze mix in the boiler circuit and replace it when the value measured is lower than the limit prescribed by the manufacturer.

DO NOT MIX DIFFERENT TYPES OF ANTI-FREEZE.

The manufacturer will not be held liable for any damage caused by the appliance or the system due to the use of inappropriate anti-freeze substances or additives.

Draining the domestic hot water system and indirect cylinder

Every time there is a danger of freezing, the domestic hot water system must be drained as follows:

• Shut off the water mains inlet valve;
• Open all the hot and cold water taps;
• Empty the water from the lowest points of the system (where applicable).

WARNING

Before handling, empty all components which may contain hot water, performing bleeding where necessary.

Descal the components in accordance with the instructions provided on the safety data leaflet supplied with the product used, make sure the room is well ventilated, wear protective clothing, avoid mixing different products, and protect the appliance and surrounding objects.

Seal all openings used to take a gas pressure reading or to make any gas adjustments.

If a smell of burning is detected or smoke is seen leaking from the appliance, or there is a smell of gas, disconnect it from the electricity supply, shut off the gas valve, open the windows and call for technical assistance.

Cleaning the primary exchanger

Cleaning the combustion side

The inside of the primary exchanger is accessed by removing the burner. Wash with water and detergent using a non-metallic rifl e-type brush, rinse with water.

Cleaning the trap

The trap is accessed by emptying the condensate bowl located in the bottom section. Wash with water and detergent.

Replace the condensate collection bowl in its housing.

NB: In the event of prolonged use of the appliance, the trap must be filled before being used again.

A lack of water in the trap is dangerous and may cause products to be released into the atmosphere.
