Advice for the installer
The installation and rst ignition of the boiler must be performed by qualied personnel in compliance with current national regulations regarding installation, and in conformity with any requirements established by local authorities and public health organisations. After the boiler has been installed, the installer must ensure that the end user receives the declaration of conformity and the operating manual, and should provide all necessary information as to how the boiler and the safety devices should be handled.
These appliance are designed for use on open vented central heating systems. A kit is available to allow the boiler to be used on a sealed system. These appliances are designed for domestic use only. It should be connected to a heating system and a distribution network for domestic hot water, both of which must be compatible with its performance and power levels. The use of the appliance for purposes other than those specied is strictly forbidden. The manufacturer cannot be held responsible for any damage caused by improper, incorrect and unreasonable use of the appliance or by the failure to comply with the instructions given in this manual. Installation, maintenance and all other interventions must be carried out in full conformity with the governing legal regulations and the instructions provided by the manufacturer. Incorrect installation can harm persons, animals and possessions; the manufacturing company shall not be held responsible for any damage caused as a result. The boiler is delivered in a carton. Once you have removed all the packaging, make sure the appliance is intact and that no parts are missing. If this is not the case, please contact your supplier. Keep all packaging material (clips, plastic bags, polystyrene foam, etc.) out of reach of children as it may present a potential hazard. In the event of a fault and/or malfunction, turn the appliance o, turn o the gas cock and do not attempt to repair it yourself. Contact a qualied professional instead. Before any maintenance or repair work is performed on the boiler, make sure you have disconnected it from the electricity supply by switching the external bipolar switch to the “OFF” position and removing the fuse. All repairs, which should only be performed using original spare parts, should be carried out by a qualied professional. Failure to comply with the above instructions could compromise the safety of the appliance and invalidate all liability on the part of the manufacturer. In the event of any maintenance or other structural work in the immediate vicinity of the ue or ue gas exhaust devices and their accessories, switch the appliance o by switching the external bipolar switch to the “OFF” position and shutting o the gas control valve. When the work has been completed, a

installation
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 ue assembly can be found in the “Connecting the Flue” section. The boiler must be installed so that the ue 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 ue terminal due to the low temperature of the ue gases. 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 etc. The minimum acceptable clearances are shown on page
12.
11
installation
The minimum acceptable clearances are shown below:
- A Directly above or 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 2500 mm
- I From a terminal facing a terminal 2500 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 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 specic 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.
12
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.
Automatic by pass
Ariston recommend that an automatic by pass is installed a minimum of 1.5 metres away from the boiler to ensure the minimum required ow rate is achieved at all times. Additionally the design of the system and its controls must ensure that an adequate temperature dierential is met, and should be such to prevent boiler cycling.

Pump specication
The pump should be tted on the ow pipe from the boiler and have isolating valves each side. A variable duty pump should be set to give a tempe­rature dierential of no greater than 20ºC.
Draining tap
A draining tap must be provided at all the lowest points of the system which will allow the entire system to be drained. A drain tap must also be installed on the ow and return pipes immediately above the boiler to ensure complete draining of the primary ow and return is possible. Drain taps shall be to the current standard of BS
2879.
Sealed water systems
A sealed system kit is available from Ariston. Installa­tion instructions are supplied with the kit.

Flushing and Water Treatment
The boiler is equipped with a stainless steel heat exchanger.
The detailed recommendations for water treatment are given in BS 7593:1992 (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 red before the system has been thoroughly ushed; the ushing procedure must be in line with BS 7593:1992.
We highly recommend the use of a ushing detergent appropriate for the metals used in the circuit. These include cleansers produced by Fernox BetzDearbon, whose function is to dissolve any foreign matter that may be in the system.
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 compromises the eciency of the thermic heat exchanger because small areas of scale cause a high increase in 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 sysem such as Fernox MB-1, BetzDearborn Sentinel X100 or Fernox System Inhibitor 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.
MTS suggests the use of suitable anti-freeze products such as Fernox ALPHI 11, which will prevent rust and incrustation taking place. Periodicaly check the pH balance of the water/anti­freeze 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-oor 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.
installation
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 specic system water treatment.
IMPORTANT Failure to carry out the water treatment procedure will invalidate the appliance guarantee.
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 benecial to the ecient operation of the system. The boiler connections for external controls are 240V. MTS 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 proong may be required when installing onto a stud partition wall). Provision must be made to allow for the correct routing of the ue and siting of the terminal to allow the safe and ecient removal of the ue products. A compartment or cupboard may be used provided that it has been built or modied 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 British Gas Document DM2, IGE/UP/7 or advice sought from CORGI.
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 specically in accordance with current IEE Wiring Regulations.
For unusual locations, special procedures may be necessary. BS 6798:2000 gives detailed guidance on this aspect.

Condensate Discharge
The condensate discharge hose from the boiler must have a continuous fall of 2.5o and must be inserted by at least 50mm into a suitable acid resistant pipe - e.g. plastic waste or over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 break upstream of the trap. ii) Connecting into the waste system of the building such as a washing maching 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.

Installing the Boiler
Please check that you are familiar with the installation requirement before commencing work (pages 8 - 16).
The installation accessories described in the following list are included in the boiler packaging:
- Hanging bracket
- A paper template (showing the dimensions of
the boiler with 5 mm side clearances)
- Gas isolation valve (compression)
- Washers
- Installation, Servicing and User manual
- Flue gasket
- Fixing screws
installation
Filling the system/condensate discharge
Fill the central heating and bleed air from the system as described in the Commissioning Instructions.
The system should be carefully checked for leaks, as frequent relling could cause premature system corrosion or unnecessary scaling of the heat exchanger.
Pay special attention not to bend the condensate silicone drain pipe is such a way as to interrupt the ow. Please only use drain pipe material compatible with condensate products (refer to BS 6798:2000).
The condensate ow can reach 2 litres/hour because of the acidity of the condensate products (Ph close to 2), take care before operation.
See page 16 for condensate discharge options.
Method of positioning the boiler on the wall
The paper template can be used to ensure the correct positioning of kitchen cabinets etc.
The paper template has to be xed to the wall and used to locate the position of the hanging bracket and the centre for the ue hole. Drill and plug the wall and secure the hanging bracket using the screws provided, ensure the hanging bracket is xed square on the wall. Remove the boiler from its packaging. Place the boiler on the hanging bracket.

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 specic legal requirements and in accordance with the maximum power of the boiler; ensure the gas isolation valve is connected correctly, see drawing opposite. 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 insucient the power may be reduced, causing inconvenience for the user.

Flue System The provision for satisfactory ue termi­nation must be made as described in BS 5440-1. The appliance must be installed so that the ue 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 ue terminal. The eect of such “steaming” must be consi­dered. If the terminal is less than 2 metres above a balcony, above ground or above a at roof to which people have access, then a suitable stain­less steel terminal guard must be tted.
The minimum acceptable spacing from the ter­minal to obstructions and ventilation openings are specied in Fig. 1.

Draw a circle around the outer ue and cut the ue to the required length taking care not to cut the inner ue, next cut the inner ue ensuring that the length between the inner and outer ue is maintai­ned. (Fig 4).
e.g. X = 555mm 811-555 = 256mm (Length to be cut from the plain end of the ue).
Once cut to the required length, ensure that the ue is free from burrs and reassemble the ue. If tting the ue from the inside of the building attach the grey outer wall seal to the ue terminal and push the ue through the hole, once the wall seal has passed through the hole, pull the ue back until the seal is ush with the wall. Alternatively, the ue can be installed from the outside of the building, the grey outer seal being tted last.
Should the ue require extending, the ue connec­tions are push t, however, one ue bracket should be used to secure each metre of ue.
Note: See table for maximum and minimum ue runs.
During use it is possible small quantities of con­densate will drip from the end of the terminal. Pay attention when siting the ue termination point.

Once the boiler has been positioned on the wall, it is ne­cessary to insert the Ø80/125 adaptor (Fig. 5) for both horizontal and vertical ue runs into the boiler ue soc­ket (not supplied with ue kit - Part No 3318095).
Push the adaptor onto the boiler’s ue connection, grease the seals then add extensions or elbows as re­quired, secure the adaptor, using the clamp and screws provided.
To t extensions or elbows it is rst necessary to en­sure that the lip seal is tted correctly into the inner ue, once veried, it is simply necessary to push them together, no clamps are necessary to secure the ue components.
Before proceeding to t the ue, ensure that the ma­ximum ue length has not been exceeded (See the tables) and that all elbows and bends have been taken into consideration, the maximum ue length is 10 metres, for each additional 90° elbow 1 metre must be subtracted from the total ue length, and for each 45° bend 0.5 metres must be subtracted from the total ue length (the height of the vertical adaptor and a 45° bend can be seen in Fig.6 and a 90° bend in Fig. 7).

The vertical ue kit is supplied with a specially de­signed weather proof terminal tted, it can be used either with a at roof or a pitched roof.
The vertical ue kits useable lengths with the pitched roof ashings are indicated in Fig. 7.
Before proceeding to t the ue, ensure that the maximum ue length has not been exceeded (See the tables) and that all elbows and bends have been taken into consideration, the maximum ue length can be found on the table on page 27 & 28. For each additional 90° elbow 1 metre must be subtracted from the total ue length, and for each 45° bend
0.5 metres must be subtracted from the total ue length (the height of the vertical adaptor and a 45° bend can be seen in Fig. 7).
Mark the position of the ue hole in the ceiling and/or roof (see Fig. 7 for distance from wall to the centre of the ue).
Cut a 130mm diameter hole through the ceiling and/or roof and t the ashing plate to the roof.
DO NOT cut the vertical ue kit.
To connect the vertical ue 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, t 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 t connection), the vertical ue kit must then be inserted through the roof ashing, this will ensure that the correct clearance above the roof is provided as the terminal is a xed height.
Should extensions be required, they are available in 1 metre (Part No. 3318077), 500mm (Part No.
3318078), they must be connected directly to the vertical starter kit before connecting the adaptor to allow the vertical ue kit to be tted. 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 ue remain ush.
When utilising the vertical ue system, action must be taken to ensure that the ue is supported adequately to prevent the weight being transferred to the appliance ue connection by using 1 ue bracket per extension.
When the ue passes through a ceiling or wooden oor, there must be an air gap of 25mm between any part of the ue system and any combustible material. The use of a ceiling plate will facilitate this. Also when the ue passes from one room to another a re stop must be tted to prevent the passage of smoke or re, irrespective of the structural material through which the ue passes.

Fitting the Twin Pipe (Ø80 / 80)
Note: See on page 27 for maximum and minimum ue runs.
Where it is not possible to terminate the ue within the distance permitted for coaxial ues, the twin ue pipe can be used by tting a special adaptor to the ue connector and using the aperture for the air intake located on top of the combustion chamber.
installation
the previous section of ue pipe or elbow, check that the o-ring is not dislodged when assembling the ue (greasing the seal will aid assembly).
Twin pipe can also be converted back to coaxial ue to enable vertical termination with a coaxial kit by using the pipe bridge (Twin - Coaxial Adaptor - Part No. 3318089). When running the twin ue pipe vertically.
It is not possible to terminate concentrically hori­zontally. Termination is only possible with separate air and exhaust terminals. When siting the twin ue 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 nal 1 metre of ue 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.
The maximum permissible ue length for twin ue is dependent on the type of run used (see table on page 28).
For further information relating to ue runs not illustrated, please contact the Technical Department on 0870 241 8180.
Always ensure that the ue is adequately supported, using one ue bracket per extension and avoiding low points. (MTS supply suitable clamps as Part No.
705778). To utilise the air intake it is necessary to:
1) Take the air intake cover o the top of the ap­pliance;
2) Assemble the ange on the header supplied with the boiler;
3) Insert the header on the tube or the elbow up until the lower stop (you do not have to use the washer);
4) Insert the elbow/header in the boiler air intake hole and fasten it with screws.
The twin ue pipes can be tted with or without ad­ditional elbows and need no clamps, simply ensure that the black o-ring is inserted in the female end of the ue pipe and push the extension piece fully into

For coaxial systems, the maximum ue lengths, mentioned in the table on page 28 also take into account an elbow. For twin ue systems the maximum ue length, mentioned in the table includes the exhaust gas/air intake terminal.
Twin ue outlets should respect the following instructions: 1- Use the same ø 80 mm 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 ue length calculation.
3- The exhaust terminal 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.

Before performing any work on the boiler, rst disconnect it from the electrical power supply using the external bipolar switch and removing the fuse.
Electrical connections
For increased safety, ask a qualied technician to perform a thorough check of the electrical system. The manufacturer is not responsible for any damage caused by the lack of a suitable earthing system or by the malfunctioning of the electricity mains supply. Make sure that the system is able to withstand the maximum power absorbed by the boiler (this is indicated on the appliance data plate). Check that the section of the wires is suitable and is not less than
0.75 mm2 The appliance must be connected to an ecient earthing system if it is to operate correctly. The power supply cable must be connected to a 230V-50Hz network, where the L-N poles and the earth connection are all respected. Important! In the event that the power supply cable must be changed, replace it with one with the same specications.

Water Treatment:
The boiler is equipped with a stainless steel heat exchanger. The detailed recommendations for water treatment are given in BS 7593:1992 (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;
Preliminar y 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 ecient.
Filling the Heating System:
Close all air release valves on the central heating system;
Open system
Fill the boiler system via the feed and expansion tank.
Sealed 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; Inspect the system for water tightness and remedy any leaks discovered.
Gas Supply:
Inspec t 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.
Under no circumstances should the boiler be fired before the system has been thoroughly flushed and refilled; the flushing procedure must be in line with BS7593:1992.

AUTO function
The AUTO function determines the best power output and ow temperature for the heating system by continually monitoring demand. It uses advanced modulating technology to clo­sely track demand and matches output with the highest precision. This ensures that either with or without the addition of further controls the activation of the AUTO function will enhan­ce boiler performance. Optimum performance can be achieved by the addition of an outdoor sensor and indoor modulating controls. Depending on the peripheral units connected and the number of zones controlled, the boiler adjusts its ow temperature automatically. The various corresponding parameters should therefore be set (see adjustments menu). To activate the function, press the Auto button.
Example 2:
single zone system (high-temperature) with on/o 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 (see pae 45).
4 23 - Perform a parallel curve shift if
necessary, increasing or decreasing the set-point temperature (this may also be modied 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).
NOTE: Two zone temperature management is
not suitable for use with Y Plan systems.
NOTE: Where an outdoor sensor is connected
and the system is supplying stored domestic hot water and a central heating circuit, each circuit must be separately connected to the PCB using the ‘RT’ and ‘Cyl’ connections.
Example 1:
single zone system (high-temperature) with on/o 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 ow 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.
40
This is to ensure a correct ow temperature to the stored hot water in the summer.

The boiler is protected from malfunctioning by means of internal checks performed by the P.C.B., which stops the boiler from operating if necessary. In the event of the boiler being shut o in this manner, a code appears on the display which refers to the type of shut-o and the reason behind it. There are two types of shut-o:
Safety shut-o
This type of error is “volatile”, which means that the boiler starts up again automatically as soon as the problem which caused the shut-o is removed; the error is indicated by the «Err» symbol which appears on the display and the error code. In fact, as soon as the cause of the shut-o disap­pears, the boiler starts up again and continues to operate normally. While the boiler is shut o for safety reasons it is possible to attempt to restore normal operation by switching the appliance o and on again using the on/o button on the control panel. If after attempting this the boiler still shows a safet shut o, switch it o and ensure that the external electrical switch is in the o position.
Shutdown
This type of error is “non-volatile”, which means that it is not removed automatically. To restore normal operation press the button on the control panel. The rst gure of the error code (e.g. 1 01) indicates within which operational assembly the error occurred. 1 - Primary Circuit 3 - Internal Electronic Part 5 - Ignition and Detection 6 - Air inlet - ue gas outlet
Malfunction warning
This warning is shown by the display in the following format: 5 P1 = FIRST IGNITION ATTEMPT UNSUCCESSFUL the rst gure indicating the operational assembly is followed by a P (warning) and the code relating to the specic warning.
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.
Anti-frost Device.
The anti-frost function acts on the central heating ow temperature probe, independently from other regulations, when the electrical supply is turned on. If the primary circuit temperature is between 3°C and 8°C the pump will run until the temperature reaches > 9°C. If the ow temperature remains between 3°C and
boiler protection devices
8°C the pump will continue to run for a maximum of 20 minutes unless a temperature above > 9°C is de tected in the central heating ow, after this the the burner will re (heating position) until a temperature of > 30°C is detected. If the central heating ow temperature is < 3°C, the burner will re (heating position) at minimum power until the temperature reaches > 30°C, the burner will go out. If lockout is caused by overheat the burner will not re but the pump will continue to run. The anti-frost device activates only when (with the boiler operating correctly):
- the boiler is electrically powered;
- there is a supply of gas.

Important
Maintenance is an essential part of the safe and ecient 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 eciency 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;
- Remove the fuse
- Close the gas isolation valve.
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 the combustion 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 and injector, if necessary.
7. Cleaning the primary heat exchanger
8. Make sure the following heating safety devices are operating correctly:
- temperature limit safety device.
9. Make sure that the following gas part safety devices are operating correctly:
- absence of gas or ame safety device (ionisation).
10. Perform a general inspection of the boiler operation.
11. Remove oxide from the detection electrode using an emery cloth.
12. After servicing, complete the relevant Service Interval Record section of the Benchmark Checklist (page 62).
13. These checks are not exhaustive. Further mechanical, electrical, condensate and combustion maintenance checks may be required.
14. Clean and rell the condensate trap
Operational test
After having carried out the maintenance operations, ll the heating circuit at a pressure of approximately 1.5 bar and release the air from the system (scaled system only).
- 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.
maintenance
- Check the ue system is sealed and operating correctly.
Draining procedures
The heating system must be drained using the
following procedure:
- Switch o the boiler, make sure the external bipolar
switch is in the OFF position;
- Open the system drain o 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 anti­scaling and anti-corrosion function, in the quantities suggested by the manufacturer, at the mimimum 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.
WARNING
Before handling, empty all components which may contain hot water, performing bleeding where necessary. Descale the components in accordance with the instructions provided on the safety data leaet supplied with the product used, make sure the room is well ventilated, wear protective clothing, avoid mixing dierent products, and protect the appliance and surrounding objects. Seal all openings used to take a gas pressure reading or to make any gas adjustments. Make sure that the nozzle is compatible with the supplied gas. 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 o the gas valve, open the windows and call for technical assistance.
Cleaning the condensate 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 lled before being used again. A lack of water in the siphon is dangerous and may cause exhaust gases to be released into the atmos­phere.
