This boiler has been designed to heat water to a temperature lower than boiling point at atmospheric pressure. It must

be connected to a central heating system and to a domestic hot water supply system according to its performance and

power output.Before having the boiler installed by a qualified service engineer, make sure the following operations are performed:

a) Make sure that the boiler is adjusted to use the type of gas delivered by the gas supply. To do this, check the markings

on the packaging and the rating plate on the appliance.

b) Make sure that the flue terminal draft is appropriate, that the terminal is not obstructed and that no exhaust gasesfrom other appliances are expelled through the same flue duct, unless the latter has been specially designed to collect

exhaust gas from more than one appliance, in compliance with current laws and regulations.c) Make sure that, if the boiler is connected to existing flue ducts, these have been thoroughly cleaned as residual pro-

ducts of combustion may detach from the walls during operation and obstruct the flow of fumes.

d) To ensure correct operation and maintain the warranty, observe the following precautions:

1. DHW circuit

1.1.If the water is harder than 20 F (1 F = 10 mg calcium carbonate per litre of water), install a polyphosphate dis-penser or an equivalent treatment system, compliant with current regulations.

1.2.Thoroughly flush the system after installation of the appliance and before use.

1.3.The materials used for the products DHW circuit comply with Directive 98/83/EC.

2. Heating circuit

2.1.new system Before proceeding with installation of the boiler, the system must be cleaned and flushed to eliminate residual

thread-cutting swarf, solder and any solvents, using suitable proprietary products. To avoid damaging metal, pla-

stic and rubber parts, only use neutral cleaners, i.e. non-acid and non alkaline. Recommended cleaning products

are:

SENTINEL X300 or X400 and FERNOX Regenerator for heating circuits. Use these products in strict compliancewith the manufacturers instructions.

2.2.existing system

Before installing the boiler, drain the system and clean it to remove sludge and contaminants, using suitable

proprietary products as described in section 2.1.

To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non-alkaline such

as SENTINEL X100 and FERNOX Protector for heating circuits. Use these products in strict compliance with themanufacturers instructions.

Remember that the presence of foreign bodies in the heating system can adversely affect boiler operation (e.g.

overheating and excessive noise of the heat exchanger).

Failure to observe the above will render the guarantee null and void.

1. INSTRUCTIONS PRIOR TO INSTALLATION

Initial lighting of the boiler must be carried out by an authorised Service Engineer who must first ensure that:

a) The rated data correspond to the supply (electricity, water and gas) data;

b) The installation complies with current laws and regulations, an excerpt of which is given in the manual intended for thefitter.

c) The appliance is correctly connected to the power supply and earthed.

The names of the authorised Service Centres are indicated in the attached sheet. Failure to observe the above will render

the guarantee null and void.

IMPORTANT:Regularly check that the pressure displayed on the pressure gauge (Figure 3a) is 0.7 - 1.5 bar, withthe boiler cold. In case of overpressure, turn on the boiler drain tap. In case of insufficient temperature, turn on the boiler

filling tap (figure 3a or 3b).

Turn on the tap very slowly in order to vent the air. During this operation, the boiler must be OFF (press( ) figure 1).

NOTE:The boiler is fitted with a hydraulic pressure gauge which prevents the boiler from working if there is no water.If pressure drops occur frequently, have the boiler checked by an authorised Service Engineer.

5. FILLING THE SYSTEM

Figure 3a

To turn off the boiler, disconnect the electric power supply. With the gas boiler in the OFF mode (section 3.2), the electric

circuits remain powered and the frost protection function is enabled (section 8).

6. TURNING OFF THE BOILER

7. GAS CONVERSION

The boilers can operate both on natural gas and LPG.Any gas change must be effected by a Qualified Service Engineer.

System filling tap

System drain tap

Pressure gauge

Do not drain the whole system as filling up with water again causes unnecessary and harmful scale to build up inside the

boiler and the heating elements. If the boiler is not used during winter and is therefore exposed to the danger of frost, addsome specific anti-freeze to the water in the system (e.g.: propylene glycol coupled with corrosion and scale inhibitors).

The electronic boiler management system includes a frost protection function for the heating system which, when flow

temperature falls below 5C, operates the burner until a flow temperature of 30C is reached.

The frost protection function is enabled if:

* the boiler is electrically powered;

* the gas tap is open;

* the system is at the correct pressure;

* the boiler is not blocked.

13. INSTALLING THE BOILERAfter deciding the exact location of the boiler, fix the template to the wall.

Connect the system to the gas and water inlets present on the lower bar of the template. Fit two G3/4 taps (flow and

return) on the central heating circuit; these taps make it possible to carry out important operations on the system without

draining it completely. If you are either installing the boiler on an existing system or replacing one, as well as the above,fit a settling tank under the boiler on the system return line in order to collect any deposits and scale circulating in the

system after flushing. After fixing the boiler to the template, connect the flue and air ducts, supplied as accessories, as

described in the following sections.If natural draught boilers are installed, connect them to the flue with a metal pipe resistant to normal mechanical stress,

heat, products of combustion and relative condensate.

15. INSTALLATION OF FLUE AND AIR DUCTS

model

240 Fi - 280 Fi - 1.240 Fi

The boiler is easy and flexible to install thanks to the extensiverange of available accessories, as described below.The boiler has been designed for connection to a vertical or hori-

zontal coaxial flue-air duct. A splitting kit is also available if sepa-rate ducts are required.

Only accessories supplied by the appliance manufacturermust be used for installation!

WARNINGTo optimise operating safety, make sure the flue ducts are firmlyfixed to the wall with suitable brackets.

COAXIAL FLUE - AIR DUCT (CONCENTRIC)

This type of duct is used to discharge exhaust fumes and drawcombustion air both outside the building and if a LAS flue is fitted.The 90 coaxial bend allows the boiler to be connected to a flue-airduct in any direction as it can be rotated by 360. It can also beused as a supplementary curve combined with a coaxial duct or a45 curve.

If fumes are discharged outside the building, the flue-air duct mustprotrude at least 18 mm from the wall to allow an aluminium wea-thering surround to be fitted and sealed to avoid water infiltrations.Make sure there is a minimum upward slope towards the outsideof 1 cm per metre of duct.

A 90 curve reduces total duct length by 1 metre. A 45 curve reduces total duct length by 0.5 metre.

SEPARATE FLUE AND AIR DUCTS

This type of installation makes it possible to discharge exhaust fumes both outside the building and into single flue ducts.

Comburent air can be drawn in at a different location from that of the flue terminal. The splitting kit comprises a flue duct

adaptor (100/80) and an air duct adaptor. For the air duct adaptor, fit the screws and seals previously removed from the

cap.

The first 90 curve is not included when calculating the maximum available length.

The 90 curve allows the boiler to be connected to a flue-air duct in any direction as it can be rotated by

B) Change the modulator voltage

set parameter F02according to the gas used, as described in

section 20.

C) Calibrate the pressure regulator

connect the positive pressure test point of a differential pres-

sure gauge (possibly water-operated) to the gas valve pres-

sure test point (Pb) (Figure 11). Connect, for sealed chambermodels only, the negative pressure test point of the pressure

gauge to a T fitting in order to join the boiler adjusting outlet,the gas valve adjusting outlet (Pc) and the pressure gauge .

(The same measurement can be carried out by connecting the

pressure gauge to the pressure test point (Pb) after removing

the sealed chamber front panel); If you measure the pressure

of burners in a different way you may obtain an altered result

in that the low pressure created in the sealed chamber by thefan would not be taken into account.

C1) Adjustment to nominal heat output

turn on the gas tap;

press (Figure 1) and switch the boiler to the winter mode

(section 3.2); turn on a hot water tap to reach a minimum 10 l/min ow rate

or ensure that maximum heating requirements are set; remove the modulator cover; adjust the brass screw (a) in Fig. 12 until the pressure values

shown in table 1 are obtained; check that the boiler feeding dynamic pressure, as measured

at the inlet gas valve pressure test point (Pa) (Figure 11) is cor-

rect (37 mbarfor propane gas, 20 mbarfor natural gas).

C2) Adjustment to reduced heat output

disconnect the modulator power cable and unscrew the screw

(b) in Fig. 12 until a pressure value corresponding to reduced

heat output is achieved (see tab.1) connect the cable again;

mount the modulator cover and seal.

C3) Final checks

mark on the data plate the type of gas and the calibration per-

formed.

The boiler has been designed in full compliance with European reference standards and in particular is equipped with the

following:

Air pressure switch (models 240 Fi - 1.240 Fi - 280 Fi) This device only allows the burner to ignite if the exhaust flue duct is in perfect working order.

In the event of one of the following faults:

the ue terminal is obstructed; the venturi is obstructed;

the fan is blocked;

pressure switch is trippedThe boiler will stay on stand-by and the display shows error code E51 or E53 (see section 9).

Fumes thermostat (model180 i AT - 1.180 i AT - 240 i)

This device has a sensor positioned on the left section of the flue extraction hood and shuts off the gas flow to the

burner if the flue duct is obstructed or in the event of draught failure.

In these conditions the boiler shuts down and displays error code E03 (section 9). To relight the main burner immediately,see section 9.

It is forbidden to disable this safety device.

Safety thermostat

This device has a sensor positioned on the left section of the flue extraction hood and shuts off the gas flow to the

burner if the flue duct is obstructed or in the event of draught failure. Under such conditions the boiler is blocked and

only after the fault has been eliminated can it be ignited again.

In these conditions the boiler shuts down and displays error code E02 (section 9).

It is forbidden to disable this safety device.

Flame ionisation detector

The flame sensing electrode, located on the right-hand side of the burner, guarantees safety of operation in case of gas

failure or incomplete ignition of the burner.

In these conditions, the boiler is blocked after 3 ignition attempts. To reset normal operating conditions, ...


hydraulic pressure switch

This device allows the main burner to be ignited only if system pressure is higher than 0.5 bars.


Pump overrun for heating circuit

The electronically-controlled pump post-circulation function lasts 3 minutes (F17 - section 20) and is enabled, in the

heating mode, if the ambient thermostat causes the burner to go out.

Pump overrun for DHW circuit

The electronically-controlled pump post-circulation function lasts 30 seconds and is enabled, in the DHW mode, if theprobe causes the burner to go out.

Frost protection device (heating and DHW systems)

The electronic boiler management system includes a frost protection function for the heating system which, whenflow temperature falls below 5C, operates the burner until a flow temperature of 30C is reached.

Water not circulating in primary circuit (pump probably blocked)

If there is insufficient or no water circulating in the primary circuit, the boiler blocks and the error code E25 is shown on

the display (section 9).

Anti-block pump function

If no heat demand is received for 24 consecutive hours, the pump will automatically start and operate for 10 seconds.

This function is operative when the boiler is powered.

Three-way valve anti-blockage function

If no heat demand is received for a period of 24 hours, the three-way valve performs a complete switching cycle. This

function is operative when the boiler is powered.

Hydraulic safety valve (heating circuit)

This device is set to 3 bar and is used for the heating circuit.

22. POSITIONING THE IGNITION AND FLAME-SENSOR ELECTRODE

Figure 16

To measure combustion performance and the toxicity of the products of combustion, the boiler is fitted with two dedica-

ted test points.

One connection point is connected to the flue gas discharge circuit, and allows monitoring of the quality of the combusti-

on products and the combustion efficiency.

The other is connected to the combustion air intake circuit, allowing checking of any recycling of the combustion productsin case of coaxial pipelines.

The following parameters can be measured at the connection point on the flue gas circuit:

temperature of the combustion products;

oxygen (O2) or carbon dioxide (CO

2) concentration;

carbon monoxide (CO) concentration.The temperature of the comburent air must be measured on the test point located on the air intake flue by inserting the

measurement sensor by about 3 cm.

For natural draught boiler models, a hole must be made in the flue gas discharge pipe at a distance from the boiler equal

to twice the inside diameter of the pipe itself.

The following parameters can be measured through this hole: temperature of the combustion products;

oxygen (O2) or carbon dioxide (CO

2) concentration;

carbon monoxide (CO) concentration.

The combustion air temperature must be measured close to the point where the air enters the boiler.

The hole, which must be made by the person in charge of operating the system when it is commissioned, must be sealed

in a way which ensures that the combustion product discharge pipe is airtight during normal operation.

Anti-legionellosis function (model 1.180 i AT - 1.240 Fi with storage boiler)

The anti-legionellosis function is NOT enabled.

To enable this function, set parameter F21=01 (as described in section 20). When the function is enabled, the electronic

management of the boiler, at weekly intervals, heats the water contained in the storage boiler to over 60C (the function

only works if the water has never exceeded 60C in the previous 7 days).

NOTE:domestic hot water is guaranteed even if the NTC sensor develops a fault.

In this case, temperature is controlled by the flow sensor.
