BOILER INSTALLATION

1.1 INSTALLATION RECOMMENDATIONS.

e Victrix 12X-20X TT 2 ErP boiler was designed for wall mounted installation only; for heating and production of domestic hot water for domestic use and similar purposes. e place of installation of the appliance and relative Immergas accessories must have suitable features (technical and structural) such to allow (always in safety, efficiency and comfortable conditions):

- installation (according to the provisions of the

technical legislation and technical regulations);

- maintenance operations (including scheduled,

periodic, routine and special maintenance);

- removal (to outdoors in the place for loading

and transporting the appliances and components) as well as their eventual replacement with appliances and/or equivalent components.

e wall surface must be smooth, without any protrusions or recesses enabling access to the rear part. ey are not designed to be installed on plinths or oors (Fig. 1-1). By varying the type of installation the classication of the boiler also varies, precisely:

- Type B23 or B53 boiler if installed using the

relevant terminal for air intake directly from the room in which the boiler has been installed.

- Type C boiler if installed using concentric

pipes or other types of pipes envisioned for sealed chamber boilers for air intake and expulsion of ue gas.

Only professionally enabled companies are authorised to install Immergas gas appliances. Installation must be carried out according to regulation standards, current legislation and in compliance with local technical regulations and the required technical procedures. Before installing the appliance, ensure that it is delivered in perfect condition; if in doubt, contact the supplier immediately. Packing materials (staples, nails, plastic bags, polystyrene foam, etc.) constitute a hazard and must be kept out of the reach of children. If the appliance is installed inside or between cabinets, ensure sucient space for normal servicing; therefore it is advisable to leave clearance of at least 3 cm between the boiler casing and the vertical sides of the cabinet. Leave adequate space above the boiler for possible water and ue removal connections. Keep all ammable objects away from the appliance (paper, rags, plastic, polystyrene, etc.). Do not place household appliances underneath the boiler as they could be damaged if the safety valve intervenes, if the drain trap is blocked, or if there are leaks from the hydraulic connections; otherwise, the manufacturer cannot be held responsible for any damage caused to the household appliances. For the aforementioned reasons, we recommend not placing furnishings, furniture, etc. under the boiler. In the event of malfunctions, faults or incorrect operation, turn the appliance o immediately and contact an authorised company (e.g. the Immergas Technical Assistance centre, which has specically trained sta and original spare parts). Do not attempt to modify or repair the appliance alone.

Failure to comply with the above implies personal responsibility and invalidates the warranty.

• Installation regulations:

- this boiler can be installed outdoors in a partially protected area. A partially protected area is one in which the appliance is not exposed to the direct action of the weather (rain, snow, hail, etc..).

is type of installation is only possible when

permitted by the laws in force in the appliance’s country of destination.

- Installation in places with a re risk is prohibited (for example: garages, closed parking stalls), gas appliances and relative ue ducts, ue exhaust pipes and combustion air intake pipes.

- Installation is prohibited on the vertical projection of cooking hobs.

- Installation is also prohibited in places/environments that constitute common parts of oce condominiums such as stairs, cellars, entrance halls, attics, los, escape routes, etc. if they are not located inside technical compartments under the responsibility of each individual building and only accessible to the user (for the features of the technical compartments, see the technical standards in force).

Attention: wall mounting of the boiler must guarantee stable and ecient support for the generator

e plugs (standard supply) are only to be used to x the appliance to the wall; they only ensure

adequate support if inserted correctly (according to technical standards) in walls made of solid or semi-hollow brick or block. In the case of walls made from hollow brick or block, partitions with limited static properties, or in any case walls other than those indicated, a static test must be carried out to ensure adequate support.

ese boilers are used to heat water to below boiling temperature in atmospheric pressure. ey must be connected to a central heating system and hot water circuit suited to their performance and capacity.

1.3 ANTIFREEZE PROTECTION. Minimum temperature -5°C. e boiler comes

standard with an anti-freeze function that activates the pump and burner when the system water temperature in the boiler falls below 4°C.

In these conditions the boiler is protected against freezing to an ambient temperature of -5°C.

Minimum temperature -15°C. In the event the boiler is installed in a place where the temperature falls below -5°C, the appliance can freeze.

To prevent the risk of freezing follow the instructions below:

- protect the central heating circuit from freezing by inserting a good-quality antifreeze liquid into this circuit, which is specially suited for central heating systems and which is manufacturer guaranteed not to cause damage to the heat exchanger or other components of the boiler. e antifreeze liquid must not be harmful to one's health. e instructions of the manufacturer of this liquid must be followed

MAINTENANCE TECHNICIAN

scrupulously regarding the percentage necessary with respect to the minimum temperature at which the system must be kept. An aqueous solution must be made with potential pollution class of water 2.

e materials used for the central heating circuit

of Immergas boilers withstand ethylene and propylene glycol based antifreeze liquids (if the mixtures are prepared perfectly).

For life and possible disposal, follow the sup-

plier's instructions.

- Protect the domestic hot water circuit against freezing by using an accessory that is supplied on request (anti-freeze kit) comprising two

electric heating elements, the relevant cables and a control thermostat (carefully read the installation instructions contained in the accessory kit pack).

In these conditions the boiler is protected against freezing to temperature of -15°C.

Boiler antifreeze protection (both -5°C and -15°C) is thus ensured only if:

- the boiler is correctly connected to gas and electricity power supply circuits;

- the boiler is powered constantly;

- the boiler is not in “o” mode;

- the boiler is not in anomaly conditions (par. 2.5);

- the essential components of the boiler and/or antifreeze kit are not faulty.

e warranty does not cover damage due to interruption of the electrical power supply and failure to comply with that stated on the previous page.

NOTE: if the boiler is installed in places where the temperature falls below 0°C the domestic hot water and central heating attachment pipes must be insulated.

CONNECTIONS

1.4 BOILER CONNECTION UNIT.

e connection unit, which is composed of all the required accessories to connect the appliance's hydraulic and gas system, is furnished as an optional kit. Execute connections as indicated in the relative instructions sheet by using the connections represented in g. 1-3.

1.5 GAS CONNECTION APPLIANCE CATEGORY II

Our boilers are designed to operate with methane gas (G20) and LPG. Supply pipes must be the same as or larger than the 3/4”G boiler tting. Before connecting the gas line, carefully clean inside all the fuel feed system pipes to remove any residue that could impair boiler eciency. Also make sure the gas corresponds to that for which the boiler is prepared (see boiler data name plate). If dierent, the appliance must be converted for operation with the other type of gas (see converting appliance for other gas types). e dynamic gas supply (methane or LPG) pressure must also be checked according to the type used in the boiler, which must comply with the technical standards in force, as insucient levels can reduce generator output and cause malfunctions. Ensure correct gas cock connection. e gas supply pipe must be suitably dimensioned according to current regulations in order to guarantee correct gas ow rate to the burner even in conditions of maximum generator output and to guarantee appliance eciency (technical specications). e coupling system must conform to technical standards in force.

Fuel gas quality. e appliance was designed to operate with combustible gas free of impurities; otherwise it is advisable to fit special filters upstream of the appliance to restore the purity of the fuel.

Storage tanks (in case of supply from LPG depot).

2H3/P

.

- New LPG storage tanks may contain residual inert gases (nitrogen) that degrade the mixture delivered to the appliance casing functioning anomalies.

- Due to the composition of the LPG mixture, layering of the mixture components may occur during the period of storage in the tanks. is can cause a variation in the heating power of the mixture delivered to the appliance, with subsequent change in its performance.

1.6 HYDRAULIC CONNECTION.

Attention: in order not to void the condensa-

tion module warranty, before making the boiler connections, carefully wash the heating system (pipes, radiators, etc.) with special pickling or descaling products to remove any deposits that could compromise correct boiler operation.

A chemical treatment of the thermal system water is required, in compliance with the technical standards in force, in order to protect the system and the appliance from deposits (e.g., lime scale), slurry or other hazardous deposits. In order not to void the heat exchanger warranty, you are required to comply with what has been prescribed in paragraph 1.21.

Water connections must be made in a rational way using the couplings on the boiler template.

Attention: Immergas declines all liability in the event of damage caused by the inclusion of automatic lling that is not its own brand.

In order to meet the system requirements established by the regulations in force in relation to the pollution of drinking water, we recommend installing the IMMERGAS anti-backow kit to be used upstream of the cold water inlet connection of the boiler. It is also recommended that the heat transfer uid (e.g. water + glycol) entered in the primary circuit of the boiler (heating circuit), complies with the local regulations in force.

Attention: to preserve the duration and the eciency features of the appliance, in the presence of water whose features can lead to the deposit of scale, installation of the “polyphosphate dispenser” kit is recommended.

3-bar safety valve. Discharge of the safety valve has been conveyed to the condensate drain trap. Consequently, in the event of valve intervention, the discharged liquid will end up in the sewer system through the drainpipe of the condensate drain trap. e appliance has anyhow been provided with a drain tting (ref. 3 g. 1-3) with a relative cap to check the presence of liquid in the drainage circuit and to check the 3-bar safety valve.

Condensate drain. To drain the condensate produced by the appliance, it is necessary to connect to the drainage system by means of acid condensate resistant pipes, with an internal Ø of at least 13 mm. e system connecting the appliance to the drainage system must be carried out in such a way as to prevent freezing of the liquid contained in it. Before appliance ignition, ensure that the condensate can be correctly removed. Aer rst ignition, check that the drain trap is lled with condensate (para. 1.22). Also, comply with national and local regulations on discharging waste waters.

1.7 ELECTRIC CONNECTION.

e appliance has an IPX5D protection degree, electrical safety of the appliance is reached only when it is connected properly to an ecient earthing system as specied by current safety standards.

Attention: Immergas S.p.A. declines any responsibility for damage or physical injury caused by failure to connect the boiler to an ecient earth system or failure to comply with the reference standards.

INSTALLERUSER

• Open the control panel connections compartment (Fig. 1-4).

To carry out electrical connections, all you have

to do is open the connections compartment as follows.

- Remove the front panel (Fig. 3-15b).

- Remove the cover (b g. 1-4).

1) Loosen the two screws (a).

2) Press the two hooks on the cover (b).

3) Remove the cover (b) from the control

panel (c).

- At this point, it is possible to access the terminal board (d).

Also ensure that the electrical installation corresponds to maximum absorbed power specications as shown on the boiler data nameplate. Boilers are supplied complete with an “X” type power cable without plug. e power supply cable must be connected to a 230V ±10% / 50Hz mains supply respecting L-N polarity and earth connection; , this network must also have a multi-pole circuit breaker with class III over-voltage category. To protect from possible dispersions of DC voltage one must provide a type A dierential safety device. When replacing the power supply cable, contact a qualied company (e.g. the Immergas Authorised Aer-Sales Technical Assistance Service). e power cable must be laid as shown (Fig. 1-3). In the event of mains fuse replacement on the P.C.B., use a 3.15A quick-blow fuse. For the main power supply to the appliance, never use adapters, multiple sockets or extension leads.

N.B.: connect terminals 36 and 37 to electrically connect the boiler to the storage tank unit, eliminating resistance R8 in the boiler (Fig. 3-2).

Installation with system operating at direct low temperature. e boiler can directly supply

a low-temperature system by setting the ow temperature adjustment range “t0” and “t1” (Par. 3.11). In this situation it is good practice to insert a relevant safety kit (optional) made up from a thermostat (with adjustable temperature). Execute connection to terminal boards 14 and 15, eliminating jumper X70 (Fig. 3-2). e thermostat must be positioned on the system ow pipe at a distance of at least 2 metres from the boiler.

1.8 REMOTE CONTROLS AND ROOM CHRONOTHERMOSTATS OPTIONAL.

e boiler is prepared for the application of room chrono-thermostats or remote controls, which are available as optional kits (Fig. 1-5). All Immergas chrono-thermostats are connected with 2 wires only. Carefully read the user and assembly instructions contained in the accessory kit.

• On/O Immergas digital chrono-thermostat.

e chrono-thermostat allows:

- set two room temperature value: one for

daytime (comfort temperature) and one for night-time (reduced temperature);

- set a weekly program with four daily switch

on and switch o times;

- select the required operating mode from the

various possible alternatives:

• manual operation (with adjustable tempera-

ture).

• automatic operation (with set programme).

• forced automatic operation (momentarily

changing the temperature of the automatic programme).

e chrono-thermostat is powered by two 1.5V

LR 6 type alkaline batteries.

• Comando Amico Remoto Remote Control De-

vice V2 (CARV2) with climate chrono-thermostat function. In addition to the functions described in the previous point, the CARV2 panel enables the user to control all the important information regarding operation of the appliance and the heating system with the opportunity to easily intervene on the previously set parameters, without having to go to where the appliance is installed. e panel is provided with self-diagnosis to display any boiler functioning anomalies. The climate chrono-thermostat incorporated into the remote panel enables

the system ow temperature to be adjusted to the actual needs of the room being heated, in order to obtain the desired room temperature with extreme precision and therefore with evident saving in running costs. e CARV2 is fed directly by the boiler by means of the same 2 wires used for the transmission of data between the boiler and device.

Important: if the system is subdivided into zones using the relevant kit, the CARV2 must be used with its climate thermostat function disabled, i.e. it must be set to On/O mode.

Comando Amico Remoto Remote Control V2 or On/O chrono-thermostat electrical connections (Optional). e operations described

below must be performed aer having removed the voltage from the appliance. Any thermostat

or On/O environment chrono-thermostat must be connected to clamps 40 and 41 eliminating jumper X40 (Fig. 3-2). Make sure that the On/ O thermostat contact is of the “clean” type, i.e. independent of the mains voltage, otherwise the P.C.B. would be damaged. Any Comando Amico Remoto Remote Control V2 must be connected to clamps 44 and 41 eliminating jumper X40 on the P.C:B., paying attention not to invert the polarity in the connections (Fig. 3-2).

Important: if the Comando Amico Remoto Remote Control V2 or any other On/Off chrono-thermostat is used, arrange two separate lines in compliance with current regulations regarding electrical systems. No boiler pipes must ever be used to earth the electric system or telephone lines. Ensure elimination of this risk before making the boiler electrical connections.

1.9 EXTERNAL TEMPERATURE PROBE OPTIONAL.

e boiler is designed for the application of the external temperature probe (Fig. 1-6), which is available as an optional kit. Refer to the relative instruction sheet for positioning of the external probe. e probe can be connected directly to the boiler electrical system and allows the max. system ow temperature to be automatically decreased when the external temperature increases, in order to adjust the heat supplied to the system according to the change in external temperature. e external probe always operates when connected, regardless of the presence or type of room chrono-thermostat used and can work in combination with Immergas chrono-thermostats. e correlation between system ow temperature and external temperature is determined by the position of the central heating selector switch on the boiler control panel (or on the CARV2 control panel if connected to the boiler) according to the curves shown in the diagram (Fig. 1-7). e electric connection of the external probe must be made on clamps 38 and 39 on the terminal board in the boiler control panel (Fig. 3-2).

1.10 IMMERGAS FLUE SYSTEMS.

Immergas supplies various solutions separately from the boilers regarding the installation of air intake terminals and ue exhaust, which are fundamental for boiler operation.

Attention: the boiler must be installed exclusively with an original Immergas “Green Range” inspectionable air intake device and fumes extraction system made of plastic, as required by the regulations in force.

e plastic pipes cannot be installed outdoors,

INSTALLERUSER

for tracts longer than 40 cm, without suitable protection from UV rays and other atmospheric agents.

is system can be identied by an identication mark and special distinctive marking bearing the note: “only for condensing boilers”.

• Resistance factors and equivalent lengths. Each

ue component has a Resistance Factor based on experimental tests and specied in the table below. e Resistance Factor for individual components is independent from the type of boiler on which it is installed and has a dimensionless size. It is however, conditioned by the temperature of the uids that pass through the pipe and therefore, varies according to applications for air intake or ue exhaust. Each single component has a resistance corresponding to a certain length in metres of pipe of the same diameter; the so-called equivalent length, can be obtained from the ratio between the relative Resistance Factors. All boilers have an

experimentally obtainable maximum Resistance Factor equal to 100. e maximum Resistance

Factor allowed corresponds to the resistance encountered with the maximum allowed pipe length for each type of Terminal Kit. This information allows calculations to be made to verify the possibility of setting up various ue congurations.

• Positioning the gaskets (black) for “green

range” ue systems. Position the gasket cor-

rectly (for bends and extensions) (Fig. 1-8):

- gasket (A) with notches, to use for bends;

- gasket (B) without notches, to use for exten-

sions;

N.B.: if necessary, to ease the push-fitting,

spread the elements with commonly-used talc.

• Coupling extension pipes and concentric elbows. To install push-tting extensions with other elements of the ue, proceed as follows: Install the concentric pipe or elbow with the male side (smooth) on the female side (with lip seal) to the end stop on the previously installed element in order to ensure sealing eciency of the coupling.

Attention: if the exhaust terminal and/or

concentric extension pipe needs shortening, consider that the internal duct must always protrude by 5 mm with respect to the external duct.

• N.B.: for safety purposes, do not obstruct the boiler intake/exhaust terminal, even temporaril y.

• N.B.: when installing horizontal pipes, a min- imum inclination of 3% must be maintained and a section clip with pin must be installed every 3 metres.

1.12 OUTDOOR INSTALLATION IN A PARTIALLY PROTECTED AREA.

N.B.: a partially protected area is one in which the

appliance is not exposed to the direct action of the weather (rain, snow, hail, etc..)..

is type of installation is only possible when permitted by the laws in force in the appliance’s country of destination.

• Conguration type B, open chamber and

forced draught.

Using the special coverage kit one can achieve

INSTALLERUSER

direct air intake (Fig. 1-9) and fumes exhaust in a single ue or directly outside. In this conguration it is possible to install the boiler in a partially protected place. In this conguration the boiler is classied as type B23. With this conguration:

- air intake takes place directly from the envi-

ronment in which the appliance is installed (outside);

- the fumes exhaust must be connected to its own

single ue (B23) or ducted directly outside via a vertical terminal for direct exhaust (B53) or via an Immergas ducting system (B53).

The technical regulations in force must be respected.

• Coverage kit assembly (Fig. 1-11). Remove

the two plugs and the gaskets present from the two lateral holes with respect to the central one. Now cover the right intake hole using the relevant plate, xing it onto the le side using the 2 previously-removed screws. Install the Ø 80 outlet ange on the central hole of the boiler, taking care to insert the gasket supplied with the kit and tighten by means of the screws provided. Install the upper cover, xing it using the 4 screws present in the kit, positioning the relevant gaskets. Engage the 90° Ø 80 bend with the male end (smooth) in the female end (with lip seal) of the Ø 80 ange unit until it stops. Introduce the gasket, making it run along the bend. Fix it using the sheet steel plate and tighten by means of the straps present in the kit, making sure to block the 4 gasket aps. Fit the male end (smooth) of the exhaust terminal into the the female end of the bend 90° Ø 80,

making sure that the relevant wall sealing plate is already tted; this will ensure hold and joining of the elements making up the kit.

Max. length of exhaust duct. e ue pipe (both vertical or horizontal) can be extended to a max. length of 30 linear metres.

• Coupling of extension pipes. To install push-tting extensions with other elements of the ue, proceed as follows: Couple the pipe or elbow with the male side (smooth) in the female side (with lip seal) to the end stop on the previously installed element. This will ensure sealing eciency of the coupling.

• Conguration without cover kit in a partially protected location (type C boiler)

By leaving the side plugs tted it is possible

to install the appliance externally without the cover kit. Installation takes place using the Ø60/100, Ø 80/125 and separator Ø 80/80 concentric intake/ exhaust kits. Refer to the paragraph relative to indoor installation. In this conguration the upper cover kit guarantees additional protection for the boiler. It is recommended but not compulsory.

1.15 SEPARATOR KIT INSTALLATION. Type C configuration, sealed chamber and fan assisted.

Separator kit Ø 80/80. is kit allows air to come

in from outside the building and the fumes to exit from the chimney or ue through divided ue exhaust and air intake pipes. Combustion products are expelled from pipe (S) (in plastic, so as to resist acid condensate). Air is taken in through duct (A) for combustion (this is also in plastic). e intake pipe (A) can be installed either on the right or le hand side of the central exhaust pipe (S). Both ducts can be routed in any direction.

• Kit assembly (Fig. 1-21): install ange (4) on the central hole of the boiler, positioning gasket (1) with the circular projections downwards in contact with the boiler ange, and tighten using the hex screws with at tip contained in the kit. Remove the at ange present in the lateral hole with respect to the central one (according to needs) and replace it with the ange (3), positioning the gasket (2) already present in the boiler and tighten using the supplied self-threading screws. Fit the male end (smooth) to the bends (5) in the female end of the anges (3 and 4). Fit the intake terminal (6) with the male side (smooth) in the female side of the bend (5) up to the end stop, ensuring that the internal and external wall sealing plates are tted. Fit the exhaust pipe (9) with the male side (smooth) to the female side of the bend (5) up to the end stop; making sure that the internal wall sealing plate has been tted, this

will ensure sealing and joining of the elements making up the kit.

• Installation clearances (Fig. 1-22). e minimum installation clearance measurements of the Ø 80/80 separator terminal kit have been stated in some limit conditions.

• Extensions for separator kit Ø 80/80. The maximum vertical straight length (without bends) that can be used for Ø 80 intake and exhaust pipes is 41 metres, regardless from whether they are used for intake or exhaust. e maximum horizontal straight length (with bend in suction and in exhaust) that can be used for Ø 80 intake and exhaust pipes is 36 metres, regardless from whether they are used for intake or exhaust.

N.B.: to favour the removal of possible condensate forming in the exhaust pipe, tilt the pipes towards the boiler with a minimum slope of

1.16 ADAPTOR C9 KIT INSTALLATION.

is kit allows to install an Immergas boiler in conguration "C93", achieving the combustion air intake directly from the sha featuring the fumes exhaust, obtained by means of a ducting system.

System composition.

e system must be combined with the following components (sold separately) to be functional and complete:

- kit C93 version Ø 100 or Ø125

INSTALLERUSER

- ducting kit Ø 60 or Ø 80

- fumes exhaust kit Ø 60/100 or Ø 80/125 congured according to the installation and type of boiler.

Kit Assembly.

- Mount the components of kit "C9" on the door (A) of the ducting system (Fig. 1-25).

- (Version Ø 125 only) mount the anged adap- tor (11) interposing the concentric gasket (10) on the boiler, tting it with the screws (12).

- Mount the ducting system as described in the relative instructions sheet.

- Calculate the distances between the boiler drain and the bend of the ducting system.

- Prepare the boiler ue system, making sure that the internal pipe of the concentric kit is tted properly in the bend of the ducting system (quota "X" g. 1-26), while the external pipe must be tted on the adaptor until it stops (1).

N.B.: to encourage the removal of possible

condensate forming in the exhaust pipe, tilt the pipes towards the boiler with a minimum slope of 1.5%.

- Mount the cover (A) complete with adaptor (1) and caps (6) on the wall and assemble the ue system to the ducting system.

N.B.: (version Ø 125 only) before assembly check the gaskets are in the right position. In the event component lubrication (already carried out by the manufacturer) is not sucient, remove the residual lubricant using a dry cloth, then to ease tting coat the parts with common or industrial talc.

Once all components have been assembled properly, the exhaust fumes will be expelled via the ducting system; the combustion air for normal boiler operation will be aspirated directly by the sha (Fig. 1-26).

Technical data.

- e dimensions of the shas must ensure a minimum gap between the outer wall of the smoke duct and the inner wall of the sha: 30 mm for circular section shas and 20 mm in the event of a square section sha (Fig. 1-24).

- Maximum 2 changes of direction are allowed on the vertical section of the ue system with a maximum clearance angle of 30° with respect to the vertical.

- e maximum vertical extension using a Ø 60 ducting system is 13 m, the maximum extension includes 1 bend Ø 60/10 at 90°, 1 m of horizontal pipe 60/100, 1 90° ducted bend Ø 60 and the roof terminal for ducting.

To determine the C93 ue system in congu-

rations other than that described (Fig. 1-26)

one must consider that 1 metre of ducted pipe according to the indications described has a resistance factor equal to 4.9.

- e maximum vertical extension using a Ø 80 ducting system is 28 m, the maximum extension includes 1 adapter 60/100 to 80/125, 1 87° bend Ø 80/125, 1 m of horizontal pipe 80/125, 1 90° ducted bend Ø 80 and the roof terminal for ducting.

To determine the C93 ue system in congura-

tions other than that described (Fig. 1-26) one must consider the following pressure drops:

- 1 m of concentric pipe Ø 80/125 = 1 m of

ducted pipe;

- 1 87° bend = 1.4 m of ducted pipe;

Consequently one must subtract the equivalent

length of the part added to the 28 m available.

1.17 DUCTING OF FLUES OR TECHNICAL SLOTS.

Ducting is an operation through which, via the introduction of one or more relevant pipes, one achieves a system for the evacuation of the combustion products of a gas appliance, made up from the coupling of an existing or new ducting pipe with a chimney, ue or technical slot (also in new buildings) (Fig. 1-27). Ducting requires ducts declared to be suitable for the purpose by the manufacturer, following the installation and user instructions provided by the manufacturer and the requirements of the local standards in force.

Immergas ducting system. e Ø 60 rigid and Ø 80 exible “Green Range” ducting systems must only be used for domestic use and with Immergas condensing boilers.

In any case, ducting operations must respect the provisions contained in the standard and in current technical regulations; in particular, the declaration of conformity must be compiled at the end of work and on commissioning of the ducted system. e instructions in the project or technical report must likewise be followed, in cases provided for by the standard and current technical regulations. e system or components of the system have a technical life complying with current standards, provided that:

- it is used in average atmospheric and envi-

ronmental conditions, according to current regulations (absence of fumes, dusts or gases that can alter the normal thermophysical or chemical conditions; existence of temperatures coming within the standard range of daily variation, etc.).

- Installation and maintenance must be per-

formed according to the indications supplied by the manufacturer and in compliance with the provisions in force.

- e max. possible length of the Ø 60 exible

ducting vertical section is equal to 22 m. is length is obtained considering the complete Ø 80 exhaust terminal, 1m of Ø 80 pipe in exhaust, two 90° Ø 80 bends at boiler outlet.

- e max. possible length of the Ø 80 exible

ducting vertical section is equal to 30 m. is

1-26

length is obtained considering the complete exhaust terminal, 1m of Ø 80 pipe in exhaust, two 90° Ø 80 bends at boiler outlet for connecting to the ducting system and two direction changes of the exible hose inside the chimney/ technical slot.

- e maximum possible length of the Ø 80 rigid ducting vertical section is equal to 30 m. is length is obtained considering the complete Ø 80 exhaust terminal, 1m of Ø 80 pipe in exhaust, two 90° Ø 80 bends on the boiler outlet.

1.18 CONFIGURATION TYPE B,

OPEN CHAMBER AND FORCED DRAUGHT FOR INDOORS.

e appliance can be installed inside buildings in 23 or B53 mode; in this case, all technical rules and national and local regulations in force, must be complied with.

- type B open chamber boilers must not be installed in places where commercial, artisan or industrial activities take place, which use products that may develop volatile vapours or substances (e.g. acid vapours, glues, paints, solvents, combustibles, etc.), as well as dusts (e.g. dust deriving from the working of wood, coal nes, cement, etc.), which may be harmful for the components of the appliance and jeopardise operation.

- in B23 and B53 conguration, the boilers must not be installed in bedrooms, bathrooms or in studio ats.

- e installation of appliances in B23 and B53 congurations are only recommended outdoors (in a partially-protected place) or in places that are not lived in and which are permanently ventilated.

To install them, one must use the coverage kit whose installation is referred to in paragraph

1.12.

1.19 FLUE EXHAUST TO FLUE/CHIMNEY.

Flue exhaust does not necessarily have to be connected to a branched type traditional ue. e ue exhaust, for boiler clots installed in C configuration, can be connected to a special

1-27

LAS type multiple ue. For B23 congurations, exhaust is only allowed into individual chimney or directly into the external atmosphere via a relevant terminal. e multiple ues and the combined ues must also only be connected to type C appliances of the same type (condensing), having nominal heat inputs that do not dier by more than 30% less with respect to the maximum that can be attached and powered by the same fuel. e thermo-uid dynamic features (ue

ow rate, % of carbon dioxide, % humidity etc....)

of the appliances attached to the same multiple ues or combined ues, must not dier by more than 10% with respect to the average boiler attached. Multiple and combined ues must be specially designed according to the calculation method and requirements of the standards in force, by professionally qualied technical sta. Chimney or ue sections for connection of the ue exhaust pipe must comply with requisites of technical standards in force.

1.20 FLUES, CHIMNEYS, CHIMNEY POTS AND TERMINALS.

e ues, chimneys and chimney pots for the evacuation of combustion products must be in compliance with applicable standards. Chimneys and roof-installed exhaust terminals must comply with the outlet height and with the distance from technical volumes set forth by the technical standards in force.

Positioning the wall ue exhaust terminals. e wall ue exhaust terminals must:

- be installed on external perimeter walls of the

building;

- be positioned according to the minimum dis-

tances specied in current technical standards.

Combustion products exhaust of natural draught or fan assisted appliances in open-top closed environments. In spaces closed on all

sides with open tops (ventilation pits, courtyards etc.), direct combustion product exhaust is allowed for natural draught or fan assisted gas appliances with a heat input range from 4 to 35 kW, provided the conditions as per the current technical standards are respected.

1.21 WATER TREATMENT SYSTEM FILLING.

As already mentioned in the previous paragraphs, a chemical treatment of the thermal system water is required, in compliance with the local standards in force.

e parameters that inuence the duration and proper operation of the heat exchanger are the water's PH, hardness, conductivity, and oxygen, together with the system's processing residues (any welding residues), any oil present and corrosion products that can, in turn, cause damage

INSTALLERUSER

to the heat exchanger.

In order to prevent this from happening, you are recommended to:

- Before installation on new systems as well as

old ones, clean the system with clean water to eliminate solid residues contained therein.

- Clean the system with a chemical treatment:

- Cle an the new system with a suitable cleaning

device (for example Sentinel X300, Fernox Cleaner F3 or Jenaqua 300) combined with thorough washing.

- Clean the old system with a suitable cleaning

device (for example Sentinel X400 or X800, Fernox Cleaner F3 or Jenaqua 400) combined with thorough washing.

- Check the maximum hardness and quantity

of lling water referring to the graphics (Fig. 1-28). If the contents and hardness of the water are below the indicated curve, no specic treatment is required; otherwise, to limit the content of calcium carbonate, you must provide for water-lling treatment.

- For lling, you are not allowed to use water

soened with the use of ionic-exchange resins or distilled water.

- Should you be required to provide for water

treatment, this should be carried out by completely desalinating the lling water. As opposed to the complete soening process, desalinating the water completely not only removes hardening agents (Ca, Mg), but also eliminates all other minerals to reduce water-lling conductivity up to 10 microsiemens/ cm. Given its low conductivity, desalinated water does not only prevent the formation of lime scale, but also serves as protection against corrosion.

- Insert a suitable inhibitor / passivator (for

example Sentinel X100, Fernot Protector F1,

MAINTENANCE TECHNICIAN

or Jenaqua 100); if required, also insert appropriate antifreeze (such as for example Sentinel X500, Fernox Alphi 11 or Jenaqua 500).

- Check electrical conduction of the water, which

should be higher than 2000 µs/cm in the case of treated water and lower than 600 µs/cm in the case of non-treated water.

- To prevent corrosion, the water system's PH

should be between 6.5 and 8.5.

- Check the maximum content of chlorides,

which should be less than 250 mg/l.

N.B.: for quantities and methods of use of water-treatment products, refer to the instructions provided by their manufacturer.

1.22 SYSTEM FILLING.

Once the boiler is connected, proceed with system lling via the lling cock (Fig. 1-30 and 1-3). Filling is performed at low speed to ensure release of air bubbles in the water via the boiler and heating system vents. e boiler has a built-in automatic venting valve on the circulator. Check if the cap is loose. Open the radiator vent valves. Close radiator vent valves when only water escapes from them. Close the lling cock when the boiler pressure gauge indicates approx. 1.2 bar.

N.B.: during these operations, enable the automatic vent functions on the boiler (active on rst ignition).

1.23 CONDENSATE TRAP FILLING.

On rst lighting of the boiler, ue gas may come out the condensate drain; aer a few minutes’ operation check that this no longer occurs. is means that the drain trap is lled with condensate to the correct level preventing the passage of ue gas.

1.24 GAS SYSTEM STARTUP.

To start up the system, refer to the technical standard in force: is divides the systems and therefore the start-up operations into three categories: new systems, modified systems, re-activated systems. In particular, for new gas systems:

- open windows and doors;

- avoid presence of sparks or open ames;

- bleed all air from the pipelines;

- check that the internal system is properly sealed according to the specications set forth by technical regulations in force.

1.25 BOILER START UP IGNITION.

In order to issue the Declaration of Conformity required by the laws in force, one must full the following requirements to commission the boiler (the operations listed below must only be performed by qualied personnel and in the presence of sta only):

- check that the internal system is properly sealed according to the specications set forth by technical regulations in force;

- ensure that the type of gas used corresponds to the boiler settings (the type of gas appears on the display on rst electrical supply voltage, or by checking the relative parameter “G”);

- check connection to a 230V-50Hz power mains, correct L-N polarity and earthing connection;

- Check that there are external factors that may cause the formation of fuel pockets;

- switch the boiler on and check correct ignition;

- make sure that the gas ow rate and relevant pressure values comply with those given in the manual (Par. 3.22);

- ensure that the safety device intervenes in the event of gas supply failure and check the relative intervention time;

- check the intervention of the main switch located upstream from the boiler and in the boiler;

- check that the intake/exhaust concentric terminal (if tted) is not blocked.

- Carry out the flue test and set the relative parameter “F0”.

e boiler must not be started up even if only one of the checks should be negative.

N.B.: solely upon completion of commissioning by an installer, an authorised company can carry out an initial check of the boiler, which is required to activate the warranty of Immergas. e test certificate and warranty is issued to the user.

N.B.: the graph refers to the entire life cycle of the system. erefore, also consider scheduled and unscheduled maintenance, which involves emptying and lling the said system.

1.26 CIRCULATION PUMP.

e boilers are supplied with a variable speed circulator pump.

In the central heating mode, the following operating modes are available and can be selected from the “P.C.B. programming” menu.

NOTE.: the ∆T can be controlled compatibly with the characteristics of the central heating system and of the boiler.

• Proportional head (∆T = 0): the circulator

speed varies according to the power emitted by the burner, the greater the power the greater the speed.

• ∆T Constant (∆T = 5 ÷ 25 K): the pump speed

varies to maintain the ∆T constant between the system ow and return according to set value K (∆T = 15 Default).

• Fixed (5 ÷ 9): by setting parameters “A3” and

“A4” at the same value, the pump operates at constant speed.

N.B.: for the boiler to work properly, it is not allowed to drop below the minimum value indicated above.

In domestic hot water mode the circulator pump always runs at maximum speed.

Pump release. If, aer a prolonged period of inactivity, the circulation pump is blocked, unscrew the front cap and turn the motor sha using a screwdriver. Take great care during this operation to avoid damage to the motor.

By-pass Regulation (part. 21 Fig. 1-30). e boiler leaves the factory with the by-pass open. If necessary, the by-pass can be regulated to system requirements from minimum (by-pass closed) to maximum (by-pass open). Adjust using a at head screwdriver, turn clockwise and open the by-pass, anticlockwise it is closed.

1.27 KITS AVAILABLE ON REQUEST.

• System shut-off valve kits with or without inspection lter (on request). e boiler is designed for installation of system interception cocks to be placed on ow and return pipes of the connection assembly. is kit is very useful for maintenance because it allows to empty just the boiler without having to empty the entire system. Moreover, the version with lter preserves the functioning characteristics of the boiler thanks to its inspectionable lter.

• System zone control unit kit (on request). If the heating system is to be divided into several zones (max. three), in order to interlock them with separate adjustments and to keep water ow rate high for each zone, Immergas supplies zone system kits by request.

• External storage tank unit coupling kit (on request). If the production of DHW is required as well as room central heating, on request Immergas supplies a kit made up from an external cylinder unit and everything necessary for adaptation of the boiler.

• Polyphosphate dispenser kit (on request). e polyphosphate dispenser reduces the formation of lime-scale and preserves the original heat exchange and domestic hot water production conditions. e boiler is prepared for application of the polyphosphate dispenser kit.

• Relay board (on request). e boiler is prepared for the installation of a relay card that allows to increase the features of the appliance and therefore functioning possibilities.

• Cover kit (on request). If installed outdoors in a partially protected place with direct air intake,it is compulsory to mount the appropriate top protection cover for the correct functioning of the boiler and to protect it from adverse weather conditions.

• Cycloidal lter kit (on request). e magnetic cycloidal filter is able to detect the ferrous residues present in the system's water. anks to the two cocks in the kit, it facilitates maintenance by cleaning the lter without having to empty the circuit.

e above-mentioned kits are supplied complete with instructions for assembly and use.

USE AND MAINTENANCE

INSTRUCTIONS

2.1 CLEANING AND MAINTENANCE. Attention: to preserve the boiler's integrity and

keep the safety features, performance and reliability, which distinguish it, unchanged over time, you must at least execute maintenance operations on a yearly basis in compliance with what is stated in the relative point at “annual check and maintenance of the appliance”. Annual maintenance is essential to validate the conventional warranty of Immergas. We recommend stipulating a yearly cleaning and maintenance contract with your zone Immergas Authorised Aer-sales Service.

2.2 GENERAL WARNINGS.

Never expose the wall-mounted boiler to direct vapours from a cooking surface. Use of the boiler by unskilled persons or children is strictly prohibited. For safety purposes, check that the concentric air intake/flue exhaust terminal (if fitted), is not blocked.

If temporary shutdown of the boiler is required, proceed as follows: a) drain the heating system if antifreeze is not

used; b) shut-o all electrical, water and gas supplies. In the case of work or maintenance to structures

located in the vicinity of ducting or devices for ue extraction and relative accessories, switch o the appliance and on completion of operations ensure that a qualied technician checks eciency of the ducting or other devices. Never clean the appliance or connected parts with easily ammable substances. Never leave containers or ammable substances in the same environment as the appliance.

• Attenzione: the use of components involving

use of electrical power requires some funda-

mental rules to be observed:

- do not touch the appliance with wet or moist

parts of the body; do not touch when barefoot;

- never pull electrical cables or leave the appli-

ance exposed to weathering (rain, sunlight, etc.);

- the appliance power cable must not be replaced by the user;

- in the event of damage to the cable, switch off the appliance and contact exclusively qualied sta for replacement;

- if the appliance is not to be used for a certain period, disconnect the main power switch.

N.B.: the temperatures indicated by the display have a tolerance of +/- 3°C due to environmental conditions that cannot be attributed to the boiler.

2.4 USING THE BOILER. Attention:

the Victrix 12X-20X TT 2 ErP boiler was designed to operate as an appliance for room central heating only or, coupled to a specic optional kit, for central heating and DHW production. For this reason the boiler control panel has a knob to adjust the temperature of DHW, but its operation is only activated by the optional kits that also enable the production of DHW. Without coupling to these specic kits, the functioning of this knob and all functions referring to DHW are

INSTALLERUSER

inhibited, apart from the calibration phase and scrolling the P.C.B. programming menu.

Before ignition make sure the heating system is lled with water and that the manometer (7) indicates a pressure of 1 ÷ 1.2 bar.

- Open the gas cock upstream from the boiler.

- Press the button (6) until the display switches on. e boiler now returns to the state prior to switch-o.

- If the boiler is in stand-by, press the button (6) again to activate it. If this is not the case, go to the next point.

- en press the button (3) in sequence and set

the boiler in the summer ( ) or winter ( ) position.

• Summer ( ): in this mode the boiler only works to produce DHW (when the boiler is connected to the external storage tank unit); the temperature is set via the selector (1) and the relative temperature is shown on the display via the indicator (14).

• Winter ( ): in this mode, the boiler works to produce DHW (when the boiler is connected to the external storage tank unit) as well as central heating. e temperature of the DHW is always regulated via the selector (1), the heating temperature is regulated via selector (4) and the relative temperature is shown on the display via the indicator (14).

From this moment the boiler functions automatically. With no demand for heat (central heating or domestic hot water production) the boiler goes to “standby” function, equivalent to the boiler being powered without presence of ame. Each time the burner ignites, the relative ame present symbol is displayed (10) with relative output scale.

• Operation with Comando Amico RemotoV2

(CARV2) (Optional). If the CARV2 is connected,

the ( ) symbol will appear on the display. e boiler regulation parameters can be set via the CARV2 control panel and the reset button (2) remains active on the boiler control panel, along with the switch-off button (6) (“off” mode only) and the display where the functioning state is shown.

Caution: if the boiler is switched “o” the

CARV2 will display the connection error symbol “ERR>CM”, the CARV2 is however powered constantly so as not to lose the stored programs.

• Operation with optional external probe ( ). In the case of a system with optional

external probe, the boiler ow temperature for room central heating is managed by the external probe depending on the external temperature measured (Par. 1.9). The flow temperature can be modied by selecting the functioning curve via the selector switch (4) (or on the CARV2 control panel, if connected to the boiler) selecting a value from “0 to 9”.

With external probe present, the relative

symbol (18) will appear on the display. In the central heating phase, if the temperature of the water contained in the system is sucient to heat the radiators, the boiler can only function with the activation of the pump.

• “Stand-by” mode. Press button (6) repeatedly until the symbol ( ) appears. From now on

the boiler remains inactive and the anti-freeze function, pump anti-block function and 3-way and signalling of any anomalies is guaranteed.

N.B.: in these conditions the boiler is still

powered.

• “O” mode. By holding the button (6) down for 8 seconds, the display switches-o and the boiler is o completely. e safety functions are not guaranteed in this mode.

IMPORTANT NOTE: in these conditions the

boiler is considered still live even if there are no functions active.

• “Automatic vent” mode. Every time the boiler is electrically powered, the system automatic vent function is activated (lasting 8 minutes). is function is displayed via a countdown signalled by the indicator (14). During this period the DHW and CH functions are not active.

e “automatic vent” can be annulled by press-

ing the “reset” button (2).

• Display operation. e display lights up while the control panel is being used; aer a set inactivity period, the brightness drops until only the active symbols are displayed. e lighting mode can be varied via parameter t8 in the P.C.B. programming menu.

2.10 ANTIFREEZE PROTECTION.

SYSTEM PRESSURE.

e “Victrix 12X-20X TT 2 ErP” series boiler features an antifreeze function that lights the burner automatically when the temperature falls below 4°C (standard protection down to min. temperature of -5°C). All information relative to the anti-freeze protection is stated in Par. 1.3. In order to guarantee the integrity of the appliance and the domestic hot water heating system in zones where the temperature falls below zero, we recommend the central heating system is protected using anti-freeze liquid and installation of the Immergas Anti-freeze Kit in the boiler. In the case of prolonged inactivity (second case), we also recommend that:

- disconnect the electric power supply;

- the central heating circuit and boiler domestic hot water circuit must be drained. In systems that are drained frequently, lling must be carried out with suitably treated water to eliminate hardness that can cause lime-scale.

3.4 TROUBLESHOOTING. N.B.: maintenance interventions must be carried

out by an authorised company (e.g. Immergas Aer-Sales Technical Assistance Service).

- Smell of gas. Caused by leakage from gas circuit pipelines. Check sealing eciency of gas intake circuit.

- Repeated ignition blocks. No gas, check the presence of pressure in the network and that the gas adduction cock is open.

- Irregular combustion or noisiness. It may be caused by: a dirty burner, incorrect combustion parameters, intake-exhaust terminal not correctly installed. Check the above components.

- Non-optimal ignition of rst ignition of the burner: even if the burner is perfectly calibrated, rst ignition of the burner (aer calibration) can be sub-optimal; the system automatically regulates ignition until it nds optimal ignition of the said burner.

- Frequent interventions of the overheating safety thermostat. It can depend on the lack of water in the boiler, little water circulation in the system or blocked pump. Check on the manometer that the system pressure is within established limits. Check that the radiator valves are not closed and also the functionality of the pump.

- Drain trap clogged. is may be caused by dirt or combustion products deposited inside. Check that there are no residues of material blocking the ow of condensate.

- Heat exchanger clogged. is may be caused by the drain trap being blocked. Check that there are no residues of material blocking the ow of condensate.

- Noise due to air in the system. Check opening of the special air vent valve cap (Part. 17 Fig. 1-30). Make sure the system pressure and expansion vessel pre-charge values are within the set limits; e factory-set pressure values of the expansion vessel must be 1.0 bar, the value of system pressure must be between 1 and 1.2 bar.

- Noise due to air inside the condensation module. Use the manual air vent valve (Part. 8 Fig. 1-30) to eliminate any air present in the condensation module. When the operation has been performed, close the manual vent valve.

- Poor production of D.H.W (when the boiler is connected to an external storage tank unit). If a drop in performance is detected during supply of D.H.W., it is possible that the condensation module is clogged. In this case, contact Immergas Aer-Sales Assistance Service that has procedures to clean the module or D.H.W. heat exchanger.

3.5 CONVERTING THE BOILER TO

OTHER TYPES OF GAS.

If the boiler has to be converted to a dierent type of gas to that specied on the data nameplate, proceed as follows: e gas conversion operation must be carried out by an authorised company (e.g. Immergas Aer-Sales Technical Assistance Service). To convert to another type of gas the following operations are required:

- Select, via programming menu “G”, the type of gas by selecting “nG” for methane gas and “LG” for LPG gas. (See par. 3.12).

- Carry out complete calibration (see par. 3.7); during the procedure check and, if necessary, correct the air - gas ratio.

- Upon completing the conversion, apply the sticker regarding the modied gas content onto the data nameplate in the connection box.

ese adjustments must be made with reference to the type of gas used, following that given in the table (Par. 3.22).

3.6 CHECKS FOLLOWING

CONVERSION TO ANOTHER TYPE OF GAS.

Aer having made sure that the conversion is complete and that the calibration has been successful, you must make sure that:

- there is no ame in the combustion chamber

- the burner ame is not too high or low and that it is stable (does not detach from burner)

- the pressure testers used for calibration are perfectly closed and there are no leaks from the gas circuit.

IMPORTANT NOTE: all boiler adjustments must be carried out by a qualied technician (e.g. Immergas Aer-Sales Te chnical Assistance).

3.7 CALIBRATION TYPE INVOLVING THE REPLACEMENT OF A COMPONENT.

When performing extraordinary maintenance on the boiler, involving the replacement of a component, such as the P.C.B. (if the removable memory is not put into the replacement board) or components in the air, gas and ame control circuits, the boiler will need to be calibrated. Select the type of calibration to be carried out according to the table below.

3.8 COMPLETE CALIBRATION FUNCTION.

N.B.: before carrying out complete calibration,

ensure that all the requirements indicated in paragraphs 1.23 and 1.24 have been fullled.

IMPORTANT NOTE: to access this function it is crucial that there are no active requests for central heating or DHW production. In the event of anomaly “62” or “72” (see parag.

2.6) the boiler cancels any requests by itself.

N.B.: during the various calibration stages, the air

- gas ratio can be checked and possibly corrected

as described in par. 3.9.

The energy produced is dissipated via the heating circuit; alternatively, the energy can be released from the DHW circuit by opening any hot water tap.

Caution: in this case the only active temperature control is the ow probe that limits the maximum temperature exiting the boiler at 90°C, therefore be careful not to get burned.

- e calibration procedure involves three stages:

- nominal heat output calibration;

- intermediate heat output ignition calibration;

- minimum heat output calibration;

- calibration self-check.

Type of calibration

required

with air-gas ratio check

Complete calibration with air-gas ratio check

Restore the parameters as described in the paragraph “P.C.B. programming” Complete calibration with air-gas ratio check

No calibration required.

Each calibration procedure, if carried out without altering the parameters, lasts 5 minutes at the most, aer which it switches automatically to the next parameter until the calibration process is complete.

In order to access the complete calibration stage, you must switch the boiler on, set the DHW selector in the “6 o' clock” position and the heating selector in the “9 o' clock” position, (Fig. 3-5) and press the “Reset” button for about 8 seconds until the “chimney sweep” function is activated; then press the “summer / winter” button within 3 seconds.

3-5

• Nominal heat output: with the function active, the boiler carries out the procedures required to calibrate the appliance at the nominal heat output.

At this stage the display features flashing

icons: “summer”, “winter”, “stand-by” and the operating temperature alternated with the current operating heat output (99%); once the parameters are detected and stabilised, the frame of the ame presence symbol (ref. 10 g. 2-1) will start ashing (this procedure may last a few minutes), meaning that the nominal heat output parameters have been set.

3-6

e air - gas ratio can only be corrected aer

the ame presence frame has ashed (see parag.

3.9) or switch to the next heat output parameter by pressing the “info” button.

• Intermediate heat output ignition: once the nominal heat output calibration is conrmed, the boiler is calibrated with the intermediate heat output (or ignition heat output).

At this stage the display features flashing

icons: “summer”, “winter”, “stand-by” and the operating temperature alternated with the current operating heat output (typically 41% but variable according to the boiler model); once the parameters are detected and stabilised, the frame of the ame presence symbol will start ashing, meaning that the intermediate heat output parameters have been set.

3-7

e air - gas ratio can only be corrected aer the ame presence frame has ashed (see parag.

3.9) or switch to the next heat output parameter by pressing the “info” button.

• Minimum heat output: aer having calibrated the boiler with the intermediate heat output, it is calibrated with the minimum heat output.

At this stage the display features flashing

icons: “summer”, “winter”, “stand-by” and the operating temperature alternated with the current operating heat output (0%); once the parameters are detected and stabilised, the frame of the ame presence symbol will start flashing, meaning that the minimum heat output parameters have been set.

3-8

e air - gas ratio can only be corrected aer

the ame presence frame has ashed (see parag.

3.9) or exit the calibration mode by pressing the “summer / winter” button.

• Calibration self-check: once calibration operations are complete, the boiler runs a self-check for about one minute. During this check, the boiler can run at dierent powers and it is not possible to apply modications to the operating parameters or to delete the operation in progress. Moreover, it is important not to cut the boiler’s power.

MAINTENANCE TECHNICIAN

3.9 ADJUSTING THE AIR GAS RATIO

During complete calibration (par. 3.8), you can modify the values of the air - gas ratio.

To have an exact value of CO2 in the ue, the technician must insert the sampling probe to the bottom of the sample point, then check that the CO2 value is that specied in the table (Par. 3.23), (with maximum tolerance equal to ± 0.2 %); otherwise, modify the value as described below:

- During calibration, when the frame of the ame presence starts ashing (indicating the

INSTALLERUSER

correct acquisition of the parameters) it is possible to alter the CO2 value by pressing the “Reset” button. At this stage the display features ashing icons: “summer”, “winter”, “stand-by”, “ame presence”, “external connected devices presence” and the operating temperature is displayed, alternated with the combustion setting.

- To increase the combustion setting, press the “Stand-by” button; to decrease it, press the “Info” button. As the combustion setting increases, the CO2 value decreases and vice-versa.

- Once the parameter has been altered wait for the value to be saved (displayed via the frame of the ame presence symbol ashing).

- To confirm the set value press the “Reset” button.

3.10 FAST CALIBRATION.

is function allows you to calibrate the boiler automatically without requiring or giving the possibility to alter the parameters. Typically “fast calibration” is used aer having set the type of ue in menu “F”, which once altered causes anomaly “72”.

N.B.: before performing a quick calibration, ensure that all the requirements indicated in paragraphs 1.21 and 1.22 have been fullled.

IMPORTANT NOTE: to access this function it is crucial that there are no active requests for central heating or DHW production.

In the event of anomaly “62” or “72” (see parag.

2.6) the boiler cancels any requests by itself.

The energy produced is dissipated via the heating circuit; alternatively, the energy can be released from the DHW circuit by opening any hot water tap.

Caution: in this case the only active temperature control is the ow probe that limits the maximum temperature exiting the boiler at 90°C, therefore be careful not to get burned.

In order to access the fast calibration stage, set the DHW selector in the “6 o' clock” position and the heating selector in the “9 o' clock” position, (Fig. 3-10) and press the “Reset” button for about

3-9

8 seconds until the “chimney sweep” function is activated; then press the “info” button within 3 seconds.

Once the function is active, the boiler sequentially carries out the procedures required to calibrate the appliance with the nominal, intermediate and minimum heat output values.

At this stage the display features ashing icons: “summer”, “winter”, “stand-by”, “external probe”, “solar probe” and the operating temperature is displayed, alternated with the current operating heat output.

e calibration stages (nominal, intermediate and minimum) progress automatically and you must wait until calibration is complete.

3.11 FLUE TEST.

To dene the value to set in the ”ue length” “F0” parameter, detect the parameters during the “ue test”.

Attention: Before performing the test, ensure that the condensate drain trap has been lled correctly and check that there are no obstructions in the air intake circuit and ue exhaust.

Once the test has been carried out properly, note the detected value in the relevant table, in order to have it available for future checks.

To activate this mode, the boiler must be in “stand-by” mode, which is visible when the

( ) symbol appears.

IMPORTANT NOTE: if the boiler is connected to the CARV2 the “stand-by” function can only be activated via the remote control panel.

To activate the function, press the “Reset” (2) and “on/o” (6) buttons simultaneously until function activation, which is displayed by indicating the fan operation speed (in hundreds of revs) and ignition of the ashing “D.H.W.” (8) and central heating symbols.

Attention: Ensure that the condensate drain trap has been lled correctly before carrying out the test.

N.B.: examinations are carried out by sealing the holes provided to analyse the ues, making them pneumatically sealed.

Attention: should there be a boiler malfunction, you can carry out a ue test to check that there are no obstructions in the ue system. Dierent values to those indicated in the previous tables indicate a ue system malfunction, especially a ue system with excessive load losses or obstructed system.

3.12 PROGRAMMING THE P.C.B.

e boiler is prepared for possible programming of several operation parameters. By modifying these parameters as described below, the boiler can be adapted according to specic needs.

To access the programming stage, set the DHW selector in the “6 o' clock” position and the heating selector in the “9 o' clock” position and press the “Reset” and “Summer/Winter” buttons for about 8 seconds (Fig. 3-14).

Once the programming mode has been accessed, scroll through the ve menus (G, P, t, A, F) by pressing the “Summer / Winter” button for 1 second.

Menu G is reserved for the air-gas control settings and it features two sub-menus (n and S), relating to fan and gas valve control settings. Every time these parameters are altered, the Complete calibration function must be activated (see parag.

3.8). In order to access parameters “n” and “S” press the “Reset” button sequentially. In order to exit this part of the menu and access other parts (categories P, t, A, F) press the “Summer / winter” button.

Use the ''D.H.W. regulator'' selector to select the parameter (within the same sub-menu) and rotate the ''C.H. regulator'' selector to alter the value. Press the "Reset" button for 1 second to store the altered parameters. If the parameters are stored successfully, "88" appears on the indicator (Ref. 14 g. 2-1) for 2 seconds.

Exit the programming mode by waiting for 15 minutes or by pressing the “Reset” and "Summer/ Winter" buttons at the same time.

Attention: if necessary the default values relating to parameters “S” and “P0 ÷ P2” can be altered by temporarily modifying the type of gas (parameter “G”) and by restoring it according to the actual operating conditions (wait for approximately 10 seconds between the gas change and the when it is restored). e restored values will be those relating to the type of boiler set in parameters “n” and “F”. At the end of this operation, anomaly “E62” will appear and complete calibration will be required.

INSTALLERUSER

e appliance remains in this mode for a maximum period of 15 minutes, keeping the fan speed constant.

is function ends once 15 minutes have elapsed, or by disconnecting supply voltage to the boiler, or by pressing the “on/o” (6) button for approximately 8 seconds.

Check the ΔP between the test pressures (g. 1-30 Ref. 13), in compliance with the values indicated in the following tables:

3.13 SOLAR PANELS COUPLING FUNCTION.

e boiler is set-up to receive water. In the event of integration of DHW heating with solar panel systems, the boiler is set by default for management of the storage tank unit via parameter “t2.” set on “2” (Par. 3.12).

3.14 "CHIMNEY SWEEP" FUNCTION.

When activated, this function forces the boiler to variable output for 15 minutes. In this state all adjustments are excluded and only the safety thermostat and the limit thermostat remain active. To activate the chimney sweep function, press the “Reset” button (2) until activation of the function in the absence of DHW requests.

Its activation on the boiler display is conrmed by the indicators ashing at the same time (11 and 12 Fig. 2-1), while on the CARV2 (optional) it is indicated as “ERR>07”.

is function allows the technician to check the combustion parameters. Once the function is activated, it is possible to select whether to make the check in CH status or DHW status (when the boiler is connected to an external storage tank unit) by opening any hot water cock and regulating the power by turning the "CH regulation" selector (6).

MAINTENANCE TECHNICIAN

e central heating or DHW operating mode is

displayed by the relative symbols or . Aer the checks, deactivate the function switch-

ing the boiler o and then on again. Attention: the boiler needs a certain amount of

time to stabilise itself before carrying out a combustion parameters check. It is thus necessary to wait for the boiler to carry out a self-diagnosis

test, which is signalled by the ( ) ashing symbol. Once the symbol stops ashing, it is possible to check the combustion parameters.

3.15 PUMP ANTIBLOCK FUNCTION.

e boiler has a function that starts the pump at least once every 24 hours for the duration of 30 seconds in order to reduce the risk of the pump becoming blocked due to prolonged inactivity.

3.16 THREEWAY ANTIBLOCK FUNCTION.

Both in “domestic hot water” and in “domestic hot water-central heating” phase the boiler is equipped with a function that starts the threeway motorised group 24 hours aer it was last in operation, running it for a full cycle so as to reduce the risk of the three-way group becoming blocked due to prolonged inactivity.

3.17 RADIATORS ANTIFREEZE FUNCTION.

If the system return water is below 4°C, the boiler starts up until reaching 42°C.

3.18 P.C.B. PERIODIC SELFCHECK.

During functioning in central heating mode or with boiler in standby, the function activates every 18 hours aer the last boiler check/power supply. In case of functioning in domestic hot water mode the self-check starts within 10 minutes aer the end of the withdrawing in progress, for duration of approx. 10 seconds.

N.B.: during self-check, the boiler remains o.

In the case of new central heating systems and in particular mode for oor systems, it is very important that dearation is performed correctly. e function consists of the cyclic activation of the pump (100 s ON, 20 s OFF) and the 3-way valve (120 s D.H.W., 120 s C.H.). e function is activated in two dierent ways:

- every time the boiler is powered;

- by pressing the buttons at the same time (3

and 5 Fig. 2-1) for 5 seconds with the boiler in stand-by.

IMPORTANT NOTE: if the boiler is connect-

ed to the CARV2 the “stand-by” function can only be activated via the remote control panel.

In the rst case, the function has duration of 8 minutes and it can be interrupted by pressing the “reset” button (2). In the second case it has duration of 18 hours and it can be interrupted by simply switching the boiler on.

Activation of the function is signalled by the countdown shown on the indicator (14).

3.20 YEARLY APPLIANCE CHECK AND MAINTENANCE.

e following checks and maintenance should be performed at least once a year.

- Check that the system's water PH is between

6.5 and 8.5.

- Visually check for water leaks or oxidation

from/on fittings and traces of condensate residues inside the sealed chamber.

- Check contents of the condensate drain trap.

- Check that there are no residues of material

clogging the condensate passage; also check that the entire condensate drainage circuit is clear and ecient.

- Visually check that the water safety drain valve

is not clogged.

- Check that, aer discharging system pressure

and bringing it to zero (read on boiler pressure gauge), the expansion vessel pressure is at 1.0 bar.

- Check that the system static pressure (with

system cold and aer relling the system by means of the lling valve) is between 1 and 1.2 bar.

- Visually check that the safety and control

devices have not been tampered with and/or short-circuited.

- Check the condition and integrity of the elec-

trical system and in particular:

- supply voltage cables must be inside the

fairleads;

- there must be no traces of blackening or

burning.

- Check ignition and operation.

- Check correct calibration of the burner in

domestic hot water and central heating phases.

- Check the operation of the appliance control

and adjustment devices and in particular:

- system regulation probes intervention;

- the intervention of the DHW adjustment

thermostat (when the boiler is connected to an external storage tank unit).

- Check sealing eciency of the gas circuit and the internal system.

- Verify the intervention of the ionisation ame control no gas device:

- Check the CO2 by using the chimney sweep function at the three reference heat outputs (Fig. 3-12). Should values out of the indicated tolerance range be detected, check the integrity of the ignition / detection electrode and, if required, change it, also changing the relative gasket. At this point, activate the “complete calibration” function.

- Carry out the flue test. Values below 40% compared to the pressures detected upon rst check, suggest a clogged burner or module (ue side).

Attention: the burner does not need to be opened for normal maintenance of the appliance. However, should it be removed, you must change the gasket.

IMPORTANT NOTE: in addition to yearly maintenance, you must also check the thermal system and energy eciency, with the frequency and procedures that comply with the technical regulations in force.
