BOILER

INSTALLATION

1.1 INSTALLATION RECOMMENDATIONS.

The Victrix 26 2 I boiler has been designed for wall mounted installation only; for heating environments and production of domestic hot water for domestic use and similar purposes. 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 B 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 the sealed chamber boiler for intake of air and expulsion of ue gases.

Only professionally enabled heating/plumbing technicians are authorised to install Immergas gas appliances. Installation must be carried out according to the 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 flue 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 not conveyed away by a draining funnel), or if there are leaks from the connections; on the contrary, the manufacturer cannot be held responsible for any damage caused to the household appliances. In the event of malfunctions, faults or incorrect operation, turn the appliance o immediately and contact a qualified technician (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..).

- Installation in places with a fire risk is prohibited (for example: garages, box), gas appliances and relative ue ducts, ue exhaust pipes and combustion air intake pipes.

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

- 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 Reference Standard).

N.B.: connection group (optional)

Important: wall mounting of the boiler must guarantee stable and ecient support for the generator.

e plugs (standard supply) are to be used only in conjunction with the mounting brackets or xing template 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.

N.B.: the hex head screws supplied in the blister pack are to be used exclusively to x the relative mounting bracket to the wall.

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 ANTIFREEZE 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. e anti-freeze function is only guaranteed if:

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

- the boiler is powered constantly;

- the boiler is not o ("o" mode);

- the boiler is not in no ignition block (Par. 2.6);

- the boiler essential components are not faulty.

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

Minimum temperature -15°C. If the boiler is installed in a place where the temperature falls below -5°C and in the event there is no gas (or the boiler goes into ignition block), the appliance can freeze.

To prevent the risk of freezing follow the instructions below:

- protect the central heating circuit from freezing by introducing a top quality anti-freeze liquid into this circuit, which is not noxious to health. e instructions of the manufacturer of this liquid must be followed 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 (EN 1717:2002).

e materials used for the central heating circuit of Immergas boilers resist ethylene and propylene glycol based antifreeze liquids (if the mixtures are prepared perfectly).

For duration and possible disposal, follow the supplier's instructions.

- Protect the condensate drain trap and circuit board 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).

Boiler anti-freeze protection is thus ensured only if:

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

- the anti-freezing kit components are ecient.

In these conditions the boiler is protected against freezing to temperature of -15°C. The warranty does not cover damage due to interruption of the electrical power supply and failure to comply with that stated above.

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

1.4 ATTACHMENTS. Gas connection (Appliance category II

2H3B/P

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-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, 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 to the burner even in conditions of maximum generator output and to guarantee appliance eciency (technical specifications). The coupling system must conform to standards.

Fuel gas quality. The appliance has been designed to operate with gas free of impurities; otherwise it is advisable to fit special filters upstream from the appliance to restore the purity of the gas.

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

- 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.

Hydraulic connection

Important: In order not to void the warranty

before making the boiler connections, carefully clean the heating system (pipes, radiators, etc.) with special pickling or de-scaling products to remove any deposits that could compromise correct boiler operation.

In compliance with Standards in force it is mandatory to treat the water in the heating system chemically, in compliance with the indications of the decree, in order to protect the system and appliance from deposits of lime scale.

Water connections must be made in a rational way using the couplings on the boiler template. e boiler safety valve outlet must be connected to a draining funnel. Otherwise, the manufacturer declines any responsibility in case of ooding if the drain valve cuts in.

Important: to preserve the duration of appliance eciency features, in the presence of water whose features can lead to the deposit of lime scale, installation of the “polyphosphate dispenser” kit is recommended . On the basis of the Standards in force, it is mandatory to treat the supply water with temporary water hardness over or equal to 25 French degrees in the central heating circuit and over than or equal to 15 French degrees for DHW, using conditioning chemicals for powers ≤ 100 kW or with soeners for powers > 100 kW

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 having an internal diameter 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 start-up, ensure that the condensate can be correctly removed. Also, comply with national and local regulations on discharging waste waters.

Electrical connection: e “Victrix 26 2 I” boiler

has an IPX4D protection rating for the entire appliance. Electrical safety of the appliance is reached only when it is correctly connected to an ecient earthing system as specied by current safety standards.

Important: 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.

Also ensure that the electrical installation corresponds to maximum absorbed power specications as shown on the boiler data-plate. 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

. is network must also have an omnipolar circuit breaker with class III over-voltage category. When replacing the power supply cable, contact a qualied technician (e.g. the Immergas Aer-Sales Technical Assistance Service). e power cable must be laid as shown (Fig. 1-4). 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.

1.5 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. All Immergas chrono-thermostats are connected with 2 wires only. Carefully read the user and assembly instructions contained in the accessory kit.

• On/O digital chrono-thermostat (Fig. 1-6).

e chrono-thermostat allows:

- to set two room temperature values: one for

day (comfort temperature) and one for night (lower temperature);

- to set up to four on/o dierential weekly

programs;

- selecting the required function mode from

the various possible alternatives:

• permanent operation in comfort temp;

• permanent operation in lower temp;

• permanent operation in adjustable anti-freeze

temp.

e chrono-thermostat is powered by two 1.5V

LR 6 type alkaline batteries.

• Comando Amico Remoto Remote Control Device

CARV2) (Fig. 1-7) with climate chrono-thermostat function. In addition to the functions described in the previous point, the CAR

panel enables the user to control all the important information regarding operation of the appliance and the heating system with the opportunity of easily intervening on the previously set parameters without having to go to the place where the appliance is installed. The Comando Amico Remoto

Remote Control panel is provided with self-diagnosis to display any boiler operating anomalies. e 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. It also allows to display the eective room temperature and the external temperature (if external probe is present). e chrono-thermostat is fed directly by the boiler by means of the same 2 wires used for the transmission of data between boiler and chrono-thermostat.

Important: if the system is divided into zones using the relevant kit. the CAR

must be used with its climate thermostat function disabled, i.e. it must be set to On/O mode.

CAR

or chrono-thermostat On/O electric

connection (Optional). e operations described

below must be performed aer having removed the voltage from the appliance. The eventual

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 supply, otherwise the P.C.B. would be damaged. Any CAR

must

be connected by means of terminals + and - to

clamps 41 and 44 on the P.C.B. (in boiler), eliminating jumper X40 and respecting polarity (Fig. 3-2). Connection with the wrong polarity prevents functioning, but without damaging the CAR

. e boiler can only be connected to one

remote control.

Important: If the CAR

remote control 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 this risk is eliminated before making the boiler electrical connections.

Installation with system operating at direct low temperature. e boiler can directly feed a

low temperature system by acting on parameters “S5” and S6” (par. 3.8). In this situation it is good practice to insert a relevant safety kit (optional) made up from a thermostat (with adjustable temperature). e thermostat must be positioned on the system ow pipe.

1.6 EXTERNAL PROBE OPTIONAL.

e boiler is prepared for the application of the external probe (Fig. 1-8), which is available as an optional kit. Refer to the relative instruction sheet for positioning of the external probe. The 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 chronothermostats. 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 CAR

control panel if connected to the boiler) according to the curves shown in the diagram (Fig. 1-9). e electric connection of the external probe must be made on clamps 38 and 39 on the terminal board positioned under the sealed chamber (Fig. 3-2).

1.7 IMMERGAS FLUE SYSTEMS.

Immergas supplies various solutions separately from the boiler regarding the installation of air intake terminals and ue exhaust; fundamental for boiler operation.

Important: the boiler must be installed exclusively with an original Immergas “Green Range” air intake and flue gas extraction system in plastic, as envisioned by Standards in force.

e plastic pipes cannot be installed outdoors, for tracts longer than 40 cm, without suitable protection from UV rays and other atmospheric agents.

This system can be identified by an identification mark and special distinctive marking bearing the note: “only for condensing boilers”.

• Resistance factors and equivalent lengths. Each ue extraction system component has a Resistance Factor based on experimental tests and specified in the table below. The resistance factor for individual components is independent from the type of boiler on which it is installed or the actual dimensions. 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 individual component has a resistance corresponding to a certain length in metres of pipe of the same diameter; the so-called equivalent length, obtained from the ratio between the relative Resistance Factors.

All boilers have an experimentally obtainable maximum Resistance Factor equal to 100.

The maximum Resistance Factor allowed corresponds to the resistance encountered with the maximum allowed pipe length for each type of Terminal Kit. is information enables calculations to verify the possibility of various congurations of ue extraction systems.

Positioning of the gaskets (black) for “green range” ue extraction systems. Position the

gasket correctly (for bends and extensions) (Fig. 1-10):

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

- gasket (B) without notches, to use for extensions;

N.B.: if component lubrication (already carried out by the manufacturer) is not sucient, remove the residual lubricant using a dry cloth, then to ease tting spread the elements with common or industrial talc.

1.8 OUTDOOR INSTALLATION IN 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..)..

• Conguration type B, open chamber and

forced draught.

Using the relevant cover kit direct air intake is possible (Fig. 1-11) and combustion products are exhausted into a single ue or directly to the 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 B

With this conguration:

- air intake takes place directly from the

environment in which the appliance is installed (external);

- the ue exhaust must be connected to its own

individual ue or channelled directly into the external atmosphere.

The technical regulations in force must be respected.

• Kit assembly (Fig. 1-12): 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 two 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. The flue pipe (vertical or horizontal) can be extended to a max.

length of 30 straight metres.

• Coupling of extension pipes. To install push-

tting extensions with other elements of the flue extraction elements assembly, 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. is will ensure sealing eciency of the coupling.

Example of installation with direct vertical terminal in partially protected location. When

the vertical terminal for direct discharge of combustion products is used, a minimum gap of 300 mm must be le between the terminal and the balcony above. e height X+Y+Z+W evaluated with respect to the balcony above, must be equal to or more than 2000 mm. (Fig. 1-14). e term W must only be considered if the balcony above has closed balustrade (W=0 if the balustrade is open).

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

By leaving the side plugs fitted it is possible to install the appliance externally without the cover kit. Installation takes place using the Ø60/100 concentric intake/ exhaust kits. Refer to the paragraph relative to indoor installation. In this configuration the upper cover kit guarantees additional protection for the boiler. It is recommended but not compulsory.

e cover kit includes: N° 1 Heat moulded cover N°1 Gasket clamping plate N°1 Gasket N°1 Gasket clamp N°1 N°1 Intake hole covering plate

e terminal kit includes: N° 1 Gasket N° 1 Exhaust ange Ø 80 N° 1 Bend 90° Ø 80 N° 1 Exhaust pipe Ø 80 N° 1 Wall sealing plate

Position it with the circular projections downwards in contact with the boiler ange and tighten using the screws preset in the kit. Fit the Ø 60/100 (3) concentric terminal pipe with the male end (smooth) to the female end of the bend (2) up to the stop; making sure that the internal and external wall sealing plate have been tted, this will ensure sealing and joining of the elements making up the kit.

N.B.: for correct functioning of the system the terminal with grid must be installed correctly ensuring that, the "high" indication present on the terminal is respected on installation.

• Coupling extension pipes and concentric elbows Ø 60/100. To push-t extensions with other elements of the ue extraction elements, operate as follows Install the concentric pipe or elbow with the male side (smooth) on the female section (with lip seal) to the end stop on the previously installed element. is will ensure sealing and joining of the elements correctly.

e kit Ø 60/100 can be installed with the rear, right side, le side or front outlet.

• Extensions for horizontal kit (Fig. 1-16). e horizontal intake-exhaust kit Ø 60/100 can be extended up to a max. horizontal distance of 12.9 m including the terminal with grid and excluding the concentric bend leaving the boiler. is conguration corresponds to a resistance factor of 100. In these cases the special extensions must be requested.

N.B.: when installing the pipes, a section clamp with pin must be installed every 3 metres.

• External grill. N.B.: for safety purposes, do not even temporarily obstruct the boiler intakeexhaust terminal.

Vertical kit with aluminium tile Ø 60/100. Kit assembly (Fig. 1-17): Install the concentric ange (2) on the central hole of the boiler, positioning the gasket (1) (which does not require lubrication) with the circular projections downwards in contact with the boiler ange and tighten using the screws present in the kit. Imitation aluminium tile installation: replace the tile with the aluminium sheet (4), shaping it to ensure that rainwater runs o. Position the xed half-shell (6) and insert the intake-exhaust pipe (5). Fit the Ø 60/100 (3) concentric terminal pipe with the male end (5) (smooth) into the ange (2) up to the stop; making sure that the wall sealing plate has been tted (3), this will ensure sealing and joining of the elements making up the kit.

Note: when the boiler is installed in areas where very rigid temperatures can be reached, a special anti-freeze kit is available that can be installed as an alternative to the standard kit.

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

Important: if the exhaust terminal and/or extension concentric pipe needs shortening, consider that the internal duct must always protrude by 5 mm with respect to the external duct.

1.10 DUCTING OF FLUES OR TECHNICAL SLOTS.

Ducting is an operation through which by the introduction of one or more relevant pipes, a system is realised 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. 1-23). Ducting requires the use of 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 standards.

Immergas ducting system. e Ø60 rigid and Ø80 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

environmental conditions, according to current regulations and in particular, by the Standard (absence of combustion products, 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

performed 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 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 tube inside the ue/technical slot.

- e max. possible length of the Ø 60 exible 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 at boiler outlet.

1.11 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 only installed in C configuration, can be connected to a special LAS type multiple ue. For B

congurations, exhaust is only allowed into individual flue 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, by professionally qualied technical sta. Chimney or ue sections for connection of the exhaust pipe must comply with requisites of technical standards in force.

1.12 FLUES, CHIMNEYS AND CHIMNEY

CAPS.

e ues, chimneys and chimney caps for the evacuation of combustion products must be in compliance with applicable standards.

Positioning the exhaust terminals. e exhaust

terminals must:

- be installed on external perimeter walls of the

building;

- be positioned according to the minimum

distances specified in current technical standards.

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

open tops (ventilation pits, courtyards etc.), direct ue exhaust is allowed for conventional or fan assisted draught gas appliances with a heating power range from 4 to 35 kW, provided the conditions as per the current technical standards are respected.

1.13 SYSTEM FILLING.

Once the boiler is connected, proceed with system lling via the lling valve (Fig. 1-25 and 2-2). Filling is performed at low speed and using the automatic vent functions 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 air vent valves. Close radiator vent valves when only water escapes from them. Close the lling valve when the boiler manometer indicates approx. 1.2 bar.

N.B.: vent the circulation pump by loosening the front cap and keeping the motor running. Re-

tighten the cap aer the operation

1.14 FILLING THE CONDENSATE TRAP.

On first lighting of the boiler combustion products may come out the condensate drain; aer a few minutes’ operation check that this no longer occurs. is means that the trap is lled with condensate to the correct level preventing the passage of combustion products.

1.15 GAS SYSTEM STARTUP.

To start up the system, make reference to the Standard: is divides the systems and therefore the start-up operations into three categories: new systems, modied systems, re-activated systems. In particular, for new gas systems:

- open windows and doors;

- avoid presence of sparks or naked ames;

- bleed all air from pipelines;

- check that the internal system is properly sealed according to specications.

1.16 BOILER START UP IGNITION.

For issue of the Declaration of Conformity provided for by Italian Law, the following must be performed for boiler start-up:

- check that the internal system is properly sealed according to specications;

- ensure that the type of gas used corresponds to boiler settings;

- switch the boiler on and ensure correct ignition;

- make sure that the gas ow rate and relevant pressure values comply with those given in the manual ( Par. 3.20);

- ensure that the safety device is engaged in the event of gas supply failure and check activation time;

- check activation of the master switch located upstream from the boiler and in the boiler;

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

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

N.B.: e boiler preliminary check must be carried out by a qualied technician. e conventional boiler warranty is valid as of the date of testing. e test certicate and warranty is issued to the user.

1.17 CIRCULATION PUMP.

e “Victrix 26 2 I” series boilers are supplied with a built-in circulation pump with 3-position electric speed control. e boiler does not operate correctly with the circulation pump on first speed. To ensure optimal boiler operation, in the case of new systems (single pipe and module) it is recommended to use the pump at maximum speed. e circulation pump is already tted with a capacitor.

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. 29 Fig. 1-25). If necessary, the by-pass can be regulated according to system requirements from a minimum (bypass excluded) to a maximum (by-pass inserted) represented by the graphics (Fig. 1-24). Make the regulation using a at head screwdriver, turn clockwise and insert the by-pass, anti-clockwise it is excluded.

1.18 KITS AVAILABLE ON REQUEST.

• System cut-off valve kits with or without inspectionable lter (on request) e boiler is designed for installation of system cut-o 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 central 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 on request.

INSTRUCTIONS FOR USE

AND MAINTENANCE.

2.1 CLEANING AND MAINTENANCE. Important: the heating systems must undergo

periodical maintenance (regarding this, see the section dedicated to the technician, relative to “yearly control and maintenance of the appliance”) and regular checks of energy eciency in compliance with national, regional or local provisions in force. is ensures that the optimal safety, performance and operation characteristics of the boiler remain unchanged over time. We recommend stipulating a yearly cleaning and maintenance contract with your zone technician.

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 anti-freeze 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 flue 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.

• Important: the use of components involving

use of electrical power requires some fundamental 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 appliance exposed to atmospheric agents (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;

2.4 USING THE BOILER.

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 (1) until the display switches on. At this point, the boiler goes to the state previous to switch-o.

- If the boiler is in stand-by, press the button (1) again to activate it. If this is not the case, go to the next point.

- Press button (2) in sequence and take the boiler

to summer (

) or winter ( ) position.

• Summer (

): in this mode the boiler

functions only to produce the DHW, the temperature is set via the selector (5) and the relative temperature is shown on the display via the indicator (14).

• Winter (

): in this mode the boiler functions

both for producing domestic hot water and heating the environment. e temperature of the DHW is always regulated via the selector (5), the heating temperature is regulated via selector (6) 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 (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 power scale.

• Operation with Comando Amico Remoto remote control

(CARV2) (Optional). If the

CAR

is connected, the ( ) symbol will appear on the display. e boiler regulation parameters can be set via the CAR

control panel and the reset button (3) remains active on the boiler control panel, along with the switch-o button (1) (“o ” mode only) and the display where the functioning state is shown

Important: if the boiler is put into "off"

mode, the “ERR>CM” connection error symbol will appear on the CAR

. e CAR V2is however powered constantly so as not to loose memorised programs.

• Solar functioning mode (

). is function

is activated automatically if the boiler detects a probe on the DHW inlet (optional) or if the “Solar ignition delay” parameter is more than 0 seconds.

During a withdrawal, if the outlet water is

hot enough, the boiler does not switch on, the DHW withdrawal symbol (

) appears

on the display along with the ashing solar

function symbol (

When the water supplied by the solar system

is at a temperature lower than that at which the boiler is set, the boiler switches on. At this point, the solar function symbol will stay on without ashing.

• Functioning 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. 1.6). The flow temperature can be modied by selecting the functioning curve via the selector switch (6) (or on the CAR

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 (1) in

succession until the (

) symbol appears. e boiler remains inactive from this moment 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

considered still powered.

• “O” mode. By holding the button (1) down

for 8 seconds, the display switches-o and the boiler is o completely. e safety functions are not guaranteed in this mode.

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

still live even if there are no functions active.

• “Automatic vent” mode. Every time power is

supplied to the boiler. the system automatic vent function is activated (duration 8 minutes). This function is displayed via countdown signalled by the indicator (14). During this period the DHW and CH functions are not active.

The “automatic vent” can be annulled by

pressing the “reset” button (4).

• Display functioning. e display lights up

during the use of the control panel, aer 15 seconds inactivity, the brightness drops until just the active symbols are displayed. The lighting mode can be varied via parameter t3 in the circuit board customisation menu.

N.B.:on the Comando Amico Remoto

remote control (Optional), the error code corresponds to the previous list with the “ERR>” indication in front (E.g. code 01 CAR

code ERR>01).

Ignition block. e boiler ignites automatically with each demand for room central heating or hot water production. If this does not occur within the pre-established time, the boiler goes into no ignition block. To eliminate “no ignition block” the Reset button (3) must be pressed. On commissioning or aer extended inactivity it may be necessary to eliminate the “no ignition block”. If this phenomenon occurs frequently,

contact a qualified technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Safety thermostat block (over-heating), ame control anomaly. During regular operation, if a

fault causes excessive overheating internally or an anomaly occurs in the ame control section, an overheating block is triggered in the boiler. To eliminate “overheating block” the Reset button (3) must be pressed. If this phenomenon occurs frequently, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Flue safety thermostat block. is occurs in the case of partial internal obstruction (due to the presence of lime scale or mud) or external blocking should occur (combustion residues) to the condensation module. To eliminate the “flue thermostat block” the Reset button (3) must be pressed. Call an authorised technician to remove the obstructions (e.g. Immergas Aersales Service).

Contacts resistance block. is occurs in the case of faults to the safety thermostat (overtemperature) or anomaly in the ame control. e boiler does not start and a technician must be called (e.g. Immergas Aer-Sales Service).

System ow probe anomaly.If the board detects an anomaly on the system NTC ow probe, the boiler will not start; contact a qualied technician for assistance (e.g. Immergas Aer-Sales Service).

Domestic hot water probe anomaly. If t he boa rd detects an anomaly on the domestic hot water NTC probe, the boiler signals the anomaly. In this case the boiler continues to produce domestic hot water but not with optimal performance. Moreover, the anti-freeze function is prevented and an authorised technician must be called (e.g. Immergas Aer-Sales Service).

Maximum N° of reset. To eliminate any anomaly, the Reset button (3) must be pressed. e Anomaly can be reset 5 times consecutively, aer which the function in inhibited for at least one hour. One attempt is gained every hour for a maximum of 5 attempts.

Insucient system pressure. Water pressure inside the central heating system that is sucient to guarantee the correct functioning of the boiler is not detected. Check on the boiler manometer (7) that the system pressure is between 1÷1.2 bar and restore the correct pressure if necessary.

Conguration error. If the board detects an anomaly or incongruency on the electric wiring, the boiler will not start. If normal conditions are restored the boiler restarts without having to be reset. If this anomaly persists, contact a qualied technician for assistance (e.g. Immergas AerSales Service).

Fan anomaly. This occurs if the fan has a

mechanical or electrical fault. To eliminate the “fan anomaly” the Reset button (3) must be pressed. Call an authorised technician if the anomaly persists (e.g. Immergas After-sales Service).

Parasite ame block.is occurs in case of a leak on the detection circuit or anomaly in the ame control unit. It is possible to reset the boiler to allow a new attempt at ignition. If the boiler does not start contact a qualified technician (e.g. Immergas Aer-Sales Technical Assistance Service).

Push button control panel anomaly. is occurs when the circuit board detects an anomaly on the push button control panel. If normal conditions are restored the boiler restarts without having to be reset. If this anomaly persists, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Service).

Block due to ue gas temperature gradient intervention. If the board detects a rapid

increase of ue gas temperature probably due to a blocked pump or lack of water in the heat exchanger, the boiler blocks due to the ue gas temperature gradient intervention. To eliminate it, the Reset button (3) must be pressed. If this phenomenon occurs frequently, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Insucient circulation. is occurs if there is overheating in the boiler due to insucient water circulating in the primary circuit; the causes can be:

- low system circulation; check that no shut-o devices are closed on the heating circuit and that the system is free of air (deaerated);

- circulating pump blocked; free the circulating pump.

If this phenomenon occurs frequently, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Flue probe anomaly. If the board detects an anomaly on the ue probe, the boiler will not start; contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Loss of Remote Control communication. is occurs 1 minute aer communication loss between the boiler and the remote control). To reset the error code, remove and re-apply voltage to the boiler. If this phenomenon occurs frequently, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

IMG Bus communication loss. If due to an anomaly on the boiler control unit, the communication is lost between the control units on the zones control unit (optional) or on the IMG Bus, the boiler does not satisfy the room central heating requests. A qualied technician must be called (e.g. Immergas AerSales Service).

Low power supply voltage is occurs when the power supply voltage is lower than the allowed limits for the correct functioning of the boiler. If normal conditions are restored, the boiler re-starts without having to be reset. If this phenomenon occurs frequently, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Loss of flame signal. This occurs when the boiler is ignited correctly and the burner ame switches off unexpectedly; a new attempt at ignition is performed and if normal conditions are restored, the boiler does not have to be reset (this anomaly can only be checked in the list of errors P19 present in the “M1” menu). If this phenomenon occurs frequently, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Block due to loss of continuous ame signal. is occurs if the "Flame signal loss" error occurs 6 times consecutively in 8.5 minutes (38)”. To eliminate the block, the Reset button (3) must be pressed. If this phenomenon occurs frequently, contact a qualified technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Block for maximum time, gas valve opening. is occurs if the gas valve remains open for a time longer than that envisioned for normal functioning, without the boiler switching on. To eliminate the block, the Reset button (5) must be pressed. If this phenomenon occurs frequently, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Low temperature safety thermostat intervention (optional). During normal

functioning, if an anomaly causes excessive overheating of the flow temperature in low temperature conditions, the boiler blocks. In this case, aer suitable cooling, it is possible to reset the thermostat (see relative instructions sheet). If this phenomenon occurs frequently, contact a qualied technician for assistance (e.g. Immergas Aer-Sales Technical Assistance Service).

Burner power limitation. If the heat exchanger is blocked, the boiler reduces the power supplied so as not to damage it. A qualied technician must be called (e.g. Immergas After-Sales Technical Assistance Service).

Signalling and diagnostics - Display of the CAR

Remote Control (Optional). During

normal boiler functioning the CAR

remote control display shows the room temperature value; in the case of malfunctioning or anomaly, the display of the temperature is replaced by the relative error code present in the previous table.

2.7 BOILER SHUTDOWN

For complete boiler switch-o, press the “o” button, disconnect the onmipolar switch outside of the boiler and close the gas cock upstream from the appliance. Never leave the boiler switched on if le unused for prolonged periods.

2.8 RESTORE HEATING SYSTEM PRESSURE

Periodically check the system water pressure. e boiler manometer should read a pressure between 1 and 1.2 bar.

If the pressure falls below 1 bar (with the circuit cool) restore normal pressure via the v alve located at the bottom of the boiler (Fig. 2-2).

N.B.:close the valve aer the operation. If pressure values reach around 3 bar the safety valve may be activated.

In this case contact a professional technician for assistance.

In the event of frequent pressure drops, contact qualied sta for assistance to eliminate possible system leakage.

2.9 DRAINING THE SYSTEM.

To drain the boiler, use the special system draining valve (Fig. 2-2) Before draining, ensure that the system lling valve is closed.

2.10 ANTIFREEZE PROTECTION.

The boiler has an anti-freeze function that switches on automatically when the temperature falls below 4°C (standard protection to minimum 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:

- the electric power supply is disconnected;

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

2.11 CASE CLEANING.

Use damp cloths and neutral detergent to clean the boiler casing. Never use abrasive or powder detergents.

2.12 DECOMMISSIONING.

In the event of permanent shutdown of the boiler, contact professional sta for the procedures and ensure that the electrical, water and gas supply lines are shut o and disconnected.

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

out by a qualified technician (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. It can be caused by

no gas, check the presence of pressure in the network and that the gas adduction valve is

open. Incorrect adjustment of the gas valve, check the correct calibration of the gas valve.

- Irregular combustion or noisiness. is may be caused by: a dirty burner, incorrect combustion parameters, intake-exhaust terminal not correctly installed. Clean the above components and ensure correct installation of the terminal, check correct setting of the gas valve (O-Set setting) and correct percentage of CO

in ue

gases.

- Frequent activation of the temperature overload 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.

- Siphon blocked. is may be caused by dirt or combustion products deposited inside. Check, by means of the condensate drain cap, that there are no residues of material blocking the ow of condensate.

- Heat exchanger blocked. is may be caused by the trap being blocked. Check, by means of the condensate drain cap, that there are no residues of material blocking the ow of condensate.

- Noise due to air in the system. Check opening of the hood of the special air vent valve (Fig. 1-25). 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.

3.4 CONVERTING THE BOILER TO OTHER TYPES OF GAS.

If the boiler has to be converted to a dierent gas type to that specied on the data plate, request the relative conversion kit for quick and easy conversion. Boiler conversion must be carried out by a qualied technician (e.g. Immergas Technical Assistance Service). To convert to another type of gas the following operations are required:

- remove the voltage from the appliance;

- replace the nozzle located between the gas pipe

and gas/air mixing sleeve (Part. 10 Fig. 1-25), taking care to remove the voltage from the appliance during this operation;

- apply voltage to the appliance;

- calibrate the number of fan revs. (Par. 3.5):

- adjust the correct air/gas ratio (Par. 3.6);

- seal the gas ow rate devices (if adjusted);

INSTALLERUSERTECHNICIAN

- aer completing conversion, apply the sticker, present in the conversion kit, near the dataplate. Using an indelible marker pen, cancel the data relative to the old type of gas.

ese adjustments must be made with reference to the type of gas used, following that given in the table (Par. 3.19).

3.5 CALIBRATION OF NUMBER OF FAN

REVS.

Important: verification and calibration is

necessary, in the case of transformation to other types of gas, in the extraordinary maintenance phase with replacement of the circuit board, air/gas circuit components or in the case of installations with ue gas extraction systems, with horizontal concentric pipe measuring more than 1 metre.

The boiler heat output is correlated to the length of the air intake and ue exhaust pipes. is decreases with the increase of pipe length. The boiler leaves the factory adjusted for minimum pipe length (1m). It is therefore necessary, especially in the case of maximum pipe extension, to check the Δp gas values aer at least 5 minutes of burner functioning at nominal heat output, when the temperatures of the intake air and exhaust ue gases have stabilised. Adjust the nominal and minimum heat output in the domestic hot water and central heating modes according to the values in the table (Par. 3.19) using the dierential manometers connected to the Δp gas pressure point (18 and 19 Fig. 1-25).

Enter the congurations menu and regulate the following parameters (Par. 3.8):

- DHW minimum power output;

- DHW maximum power output;

- minimum heating output;

- maximum central heating output;

- ignition power.

3.6 ADJUSTMENT OF THE AIRGAS RATIO.

Important: the verication operations of the CO

must be carried out with the casing mounted, while the gas valve calibration operations must be carried out with the casing open and removing the voltage from the boiler.

Calibration of the minimum CO

(minimum heating power). Enter the chimney sweep phase without withdrawing domestic hot water and take the selector switches to minimum (turn them in an anti-clockwise direction until "0" is seen on the display). to have an exact value of CO

in the ue gases the technician must insert the sampling probe to the bottom of the sample point, then check that the CO

value is that specied in the table, otherwise adjust the screw (3 Fig. 3-4) (OSet adjuster). To increase the CO

value, turn the adjustment screw (3) in a clockwise direction and vice versa to decrease it.

Calibration of the maximum CO

(nominal central heating power). On completion of the adjustment of the minimum CO

keeping the chimney sweep function active, take the heating selector switch to maximum (turn it in a clockwise direction until “99” is seen on the display). To have an exact value of CO

in the ue gases the technician must insert the sampling probe to the bottom of the sample point, then check that the CO

value is that specied in the table, otherwise adjust the screw (12 Fig. 3-4) (Gas ow adjuster). To increase the CO

value, turn the adjustment screw (12) in an anti-clockwise direction and vice versa to decrease it.

3.9 SOLAR PANELS COUPLING FUNCTION.

e boiler is set-up to receive pre-heated water from a system of solar panels up to a maximum temperature of 65°C. In all cases, it is always necessary to install a mixing valve on the hydraulic circuit upstream from the boiler on the cold water inlet.

Note: for good functioning of the boiler; the temperature selected on the solar valve must be 5 °C greater with respect to the temperature selected on the boiler control panel.

In this condition, parameter P0 (DHW thermostat) must be set at “1” and the parameter P1 (solar delay time) at a temperature sucient to receive water from a storage tank situated upstream from the boiler. The greater the distance from the storage tank, the longer the stand-by time to be set. When these regulations have been performed, when the boiler inlet water is at the same or greater temperature with respect to that set by the DHW selector switch, the boiler does not switch on.

3.10 "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 (3) until activation of the function in the absence of DHW requests.

Its activation is signalled by simultaneous ashing of the indicators (11 and 12 Fig. 2-1).

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 by opening any hot water cock and regulating the power by turning the "CH regulation" selector (6). Functioning in CH or DHW mode is visualised

by the relative symbols

or .

After the checks, deactivate the function switching the boiler o and then on again.

3.11 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.

3.12 THREEWAY ANTIBLOCK SYSTEM

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.

3.13 RADIATORS ANTIFREEZE FUNCTION.

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

3.14 P.C.B. PERIODICAL SELFCHECK.

During functioning in 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.

3.15 AUTOMATIC VENT FUNCTION.

In the case of new heating systems and in particular mode for floor systems, it is very important that dearation is performed correctly. e function consists in the cyclic activation of the pump (100 s ON, 20 s OFF) and the 3-way valve (120 s domestic hot water, 120 s central heating). e function is activated in two dierent ways:

- at every new power supply of the boiler;

- by pressing buttons at the same time (2 and 4

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

N.B.: if the boiler is connected to the CAR

, the “stand-by” function is only obtained 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 (4). 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).

3.16 SYSTEM SUPERVISION COUPLING FUNCTION.

e boiler is set-up to be coupled to a system functioning with heat pump. For coupling, a "System supervisor" kit is necessary and the following operations must be performed:

- set “S7” on “CE”;

- connect the system supervisor to clamps 38

(-) and 39 (+) of the boiler terminal board respecting the polarity.

For further information, see the system supervisor instruction book.

3.17 YEARLY APPLIANCE CHECK AND MAINTENANCE.

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

- Clean the ue side of the heat exchanger.

- Clean the main burner.

- Check correct lighting and operation.

- Ensure correct calibration of the burner in

domestic water and heating phases.

- Check correct operation of control and

adjustment devices and in particular:

- intervention of main electrical switch on

boiler;

- system control thermostat intervention;

- domestic hot water control thermostat

intervention.

- Check sealing eciency of gas circuit and the

internal system.

- Check intervention of the device against no gas

ionisation ame control:

- check that the relative intervention time is

less than 10 seconds.

- Visually check for water leaks or oxidation

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

- Check, by means of the condensate drain cap,

that there are no residues of material blocking the ow of condensate.

- Check contents of the condensate drain trap.

- Visually check that the water safety drain valve

is not blocked.

- Check that, aer discharging system pressure

and bringing it to zero (read on boiler manometer), the expansion vessel charge 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.

- Check visually that the safety and control

devices have not been tampered with and/or shorted, in particular:

- temperature safety thermostat;

- Check the condition and integrity of the

electrical system and in particular:

- electrical power cables must be inside the

whipping;

- there must be no traces of blackening or

burning.

N.B.: on occasion of periodical maintenance of the appliance it is appropriate also to check and perform maintenance on the heating system, in compliance with that indicated by the regulations in force.

3.18 CASING REMOVAL.

To facilitate boiler maintenance the casing can be completely removed as follows:

- disassemble the lower plastic protection grid (1) by loosening the two lower screws (2);

- loosen the two screws (4) present in the lower part of the casing front (3);

- Unhook the central xing (6) exerting slight pressure in the median zone of the side (5);

- pull the front casing slightly in the lower part towards yourself and push upwards at the same time (see gure);

- loosen the 2 front screws on the control panel (7);

- loosen the screws (8) present in the front part of the two sides (5);

- pull the sides lightly to the outside and loosen the two rear screws using a screwdriver with long point (9).

3.19 VARIABLE HEAT POWER.

N.B.: the pressures indicated in the table repre-

sent the dierences of pressures at the ends of the Venturi mixer and can be measured from the pressure point in the upper part of the sealed chamber (see pressure test 18 and 19 Fig. 1-25). e adjustments must be performed using a digital dierential manometer with a scale in

tenths of mm or Pascal. e power data in the table has been obtained with intake-exhaust pipe measuring 0.5 m in length. Gas ow rates refer to heating values below a temperature of 15°C and at a pressure of 1013 mbar. Burner pressure values refer to use of gas at 15°C.
