1. OPERATIONG INSTRUCTIONS

1.1 Introduction

Dear Customer,

Thank you for choosing DOMlcompact F 30 B, a FERROLI wall-mounting boiler featuring advanced design and technology, high reliability and quality construction. Please read this manual carefully and keep it for future reference.

DOMlcompact F 30 B is a high-efficiency condensing appliance for heating and hot water production running on natural or liquefied petroleum gas (configurable at the time of installation) and regulated by an advanced microprocessor control system.

The boiler shell consists of a primary copper laminar heat exchanger, a secondary aluminium heat exchanger providing effective condensation of the water vapour contained in the flue gases, and burner equipped with electronic ignition and ionization flame control.

The boiler is totally room sealed from the installation room: the air needed for combustion is drawn from outside. The boiler also includes a fan, modulating gas valve, pump, expansion vessel, flow meter, safety valve, temperature sensors, a safety thermostat and a low water pressure switch.

Thanks to the microprocessor control and adjustment system with advanced self-diagnosis, unit operation is for the most part automatic. The power for heating is automatically governed by the control system according to the indoor and outdoor characteristics (with an optional outdoor sensor installed), the characteristics of the building and of its location. The power for hot water is automatically and continually governed to ensure a fast delivery and comfort under all operating conditions.

The user only has to set the temperature desired inside the home (by means of an optional room thermostat or remote control, which is required under the building regulations 2002) or regulate the temperature of the system, and set the desired outlet temperature for the hot water. The adjustment and control system will provide optimum operation throughout the year.

The display continuously provides information on the unit's operating status and it is possible to obtain additional information on the sensor temperatures, set-points, etc. or configure them. Any operating problems associated with the boiler or system are immediately signalled by the display and, if possible, corrected automatically.

1.2 Control panel

The control panel is composed of a multi-function button, two knobs and a display.

When the boiler is turned off, the PCB is still powered.

Hot water and heating operation are disabled, the display shows

but the frost protection function stays on

The frost protection will not work if the electricity and/or gas supply to the unit are cut off. To avoid damage caused by freezing during long shutdowns in winter, it is advisable to drain all water from the boiler, the tap water and the system water; or drain off just the tap water and add a suitable antifreeze to the heating system, as prescribed in chap. 2.3.

1.4 Adjustments

Summer/winter Switchover

Depending on the position of the control knobs "1" and "2" it is possible to switch off the boiler unit, switch between summer and winter operation or turn off the domestic hot water.

Switching off the boiler, switching between summer and winter operation and turning off hot tap water has priority over the remote timer control (optional) when this is connected to the boiler.

C.H. temperature setting

To set the system delivery temperature, turn the knob (ref. 1 - Fig. 1).

It can vary from a minimum of 30\ °C to a maximum of 85\ °C ; however, it is advisable not to operate the boiler below 45\ °C . When the knob is turned the display lights up, the radiator symbol flashes and the temperature displayed will be the temperature actually set. On completing this operation, the display will stay on for another 5 seconds and then go back to the actual operating temperature providing there is a demand.display.

Domestic Hot water temperature adjustment

To set the tap water temperature, turn the knob (ref. 2 - Fig. 1).

It can vary from a minimum of 40\ °C to a maximum of 55\ °C . When the knob is turned the display lights up, the tap symbol flashes and the temperature displayed will be the temperature actually set. On completing this operation, the display will stay on for another 5 seconds to then go back to the actual operating temperature providing there is a demand.

If the boiler is connected with the optional remote timer control, the above adjustments (system and hot water temperature) can be made with the remote control.

ECO/COMFORT selection

The unit is equipped with a special internal device that ensures a high hot-water delivery speed and excellent user comfort. When the device is working (COMFORT mode), the water in the boiler is kept at temperature, which means that hot water is available at the boiler outlet as soon as a tap is opened, with no waiting.

The user can turn the device off (ECO mode) by pressing the multi-function button for 2 seconds with the boiler on standby. In ECO mode the display shows the relevant symbol. To turn on COMFORT mode, press the multi-function button again for 2 seconds, the ECO symbol will vanish from the display.

TEST MODE selection

Pressing the multi-function button 3 times in 3 seconds turns on TEST mode (the heating and hot water symbols blink simultaneously - see par. 3.1). If TEST mode is turned on by accident, press the button 3 times in 3 seconds again to exit. (Test time 15 minutes unless cancelled early)

1.5 Maintenance

It is strongly recommended to carry out annual maintenance on the boiler and the heating system. Please refer to the "maintenance" section in this manual.

The casing, the control panel and the aesthetic parts of the boiler can be cleaned using a soft and damp cloth.

Do not use abrasives or solvents.

1.6 Faults

The boiler is equipped with an advanced self-diagnosis system that signals any faults on the display. Some faults (from F1 to F3) cause a boiler shutdown. In this case, operation must be reset manually by pressing the multi-function button (RESET) for 1 second or with the optional remote timer control if one has been installed. Other faults (from F5 to F37) cause temporary shutdowns that are automatically reset as soon as the value causing the fault comes back within the boiler's normal working range.

Listed below are the anomalies that can be caused by simple, user-solvable problems.

If the problem remains after two attempts at resetting, contact your nearest Service Centre.

For other faults, refer to section 3.4 "Troubleshooting".

For Northern Ireland the rules in force apply

2.2 Boiler location

The boilers combustion chamber is sealed off from the installation room. The installation room must be sufficiently well ventilated to prevent any dangerous conditions from forming in the event of even slight gas leakage. This safety standard is required by the EEC Directive no. 90/396 for all gas units, including those with a so-called sealed chamber.

Therefore the place of installation must be free of dust, flammable materials or objects or corrosive gases. The room must be dry and not subject to freezing.

The boiler is design to be installed on a solid wall. The wall fixing must ensure a stable and effective support for the appliance, using the bracket and fixings supplied.

If the unit is enclosed in a cupboard or mounted alongside, there must be space for normal maintenance work. Fig. 2 and tab. 1 give the minimum clearances to leave around the unit.

This appliance does not require compartment ventilation for combustion purposes

fig. 2

Table 1
	Minimum
A	5 cm
B	20 cm
C 20 cm
D	60 cm(via an openable panel)

Drilling Template

Select suitable mounting position for boiler, using the template mark flue outlet and boiler mounting points. Drill two 10mm holes 70mm deep to accept the wall plugs. Fit standard wall plugs on the left and right side and the special wall plug in the middle (fig. 3). Fix the wall bracket to the wall using standard lock nut (M8) on both sides. Mount the boiler on the wall bracket and fix using the special antitheft nut (M8) as described in the fig. 3. Using a core drill cut a 118mm diameter hole for the flue as detailed on page 17.

Make Up Water

Provision must be made for replacing water lost from the sealed system. Reference should be made to BS6798, for methods of filling and making up sealed systems. There must be no direct connection between the boiler's central heating system and the mains water supply. The use of mains water to charge and pressurise the system directly, is conditional upon the Local Water Byelaws. Again any such connection must be disconnected after use. The temporary filling loop (not supplied) is shown in fig. 5. Ensure the filling point is on the return pipe to the boiler.

Attention - is drawn to the Local Water Byelaws.

Fittings manufactured from duplex (alpha-beta) brass are not acceptable for underground use and certain water undertakings will not accept their use above ground.

Ensure all pipework is adequately supported

NOTE: An automatic bypass capable of passing 6 ltrs per minute must be fitted as far as possible from the boiler if thermostatic radiator valves are fitted throughout.

2.3 Boiler water connections

The heating capacity of the unit should be previously established by calculating the building's heat requirement according to current regulations. For good operation and long life of the boiler, the plumbing system must be well proportioned and always complete with all those accessories that guarantee efficient operation and running, room thermostat, trv's and automatic bypass.

If the delivery and return pipes follow a path where air pockets could form in certain places, it is essential to install air vent valves at these points. Also, install a type "A" drain cock device at the lowest point in the system to allow its complete draining.

The temperature differential between the flow manifold and the return to the boiler should not exceed 20° C.

A minimum flow of 6 litres/min is required through the heat exchanger, it is therefore essential to fit a automatic bypass a min of 3 metres away from the appliance, calibrated on site.

Do not use the water system pipes to earth electrical appliances.

Before installation, carefully flush all the pipes of the heating system to remove residues or impurities that could affect the unit's good working (BS 7593 Building regs Doc L).

Make the connections to the appliance as shown in fig. 6.

Key

1 System flow (22 mm with isolation valve fitted)
2 DHW outlet (15 mm with isolation valve fitted)
3 Gas inlet (22 mm with isolation valve fitted)
4 Cold main inlet (15 mm with isolation valve fitted)
5 System return - 22 mm with isolation valve fitted (c/w filter)
6 Condense outlet

fig. 6

It is essential to install the isolation valves supplied between the boiler and heating system, allowing the boiler to be isolated from the system if necessary.

The safety valve outlet must be connected to a 15 mm pipe to discharge outside the property in the event of over-pressure in the heating circuit. If this is not done, and the drain valve trips and floods the room, the boiler manufacturer is not to be held responsible. The outlet should face back against the outer brickwork or building face to prevent harm or injury from hot water discharging in the evet of an over-pressuried system.

Make the boiler connection in such a way that its internal pipes are free of stress. If a check valve is installed on the tap water circuit (where applicable), it is necessary to mount a safety valve between the boiler and this circuit (check valve minimum 3 metres from boiler).

The connecting kits shown in fig. 7 are supplied as standard.

Note - When the boiler is installed with an existing or new system any unsuitable additives or system debris must be removed by thorough cleansing. All systems should be cleansed according to B.S. 7593.

Note - In hard water areas treatment to prevent lime scale may be necessary.

Note - It is important that the correct concentration of the water treatment product is maintained in accordance with the manufacturers instructions.

2.4 Connection to the gas system

If necessary the local Gas supplier should be consulted, at the installation planning stage, in order to establish the availability of an adequate supply of gas.

An existing service pipe must not be used whitout prior consultation with the local Gas supplier.

A gas meter can only be connected by the Local Gas supplier, or by a Local Gas suppliers Contractor.

Installation pipes should be fitted in accordance with BS6891.

Appliance inlet working pressure must be 20 mbar MINIMUM, for NG and 37 mbar minimum for propane.

Do not use pipes of a smaller size than the combination boiler inlet gas isolation valve (22 mm).

The complete installation must be tested for gas soundness and purged as described in BS6891. All

A pipework must be adequately supported. An isolating gas valve is provided and should be fitted on the boiler gas inlet. Please wait 10 minutes when ligthing from cold before checking the gas rate. Gas pressures should be checked after the boiler has operated for 10 minutes to ensure thermal equilibrium.

2.5 Electrical Connections

The unit must be installed in conformity with current national and local regulations inc 16th Edition & B.S. 7671.

Connection to the electrical supply

The boiler must be connected to a single-phase, 230 Volt-50 Hz electrical supply.

Connection with concentric flue system

The unit can be connected to a concentric air/flue duct with a wall or rooftop outlet as shown on the following drawings. Numerous accessories are available on request to meet the various installation requirements. Please refer to our "flue manual" or the price list.

Horizontal concentric flue installation

L = S + D + 163,5 mm

Horizontal flue installation

1. Define the suitable position for installing the boiler (see 2.2 boiler location)
2. When installing a horizontal flue kit, please ensure a 3mm per metre fall back to the appliance is incorporated
3. Make a hole of diameter 10 - 20 mm greater than the nominal diameter of the concentric pipe used.

4. If necessary, cut the end pipe to size, ensuring that the external pipe protrudes from the wall by between 10 and 60 mm (Fig. 10a and 10b). Remove the cutting burrs and lubricate the seals with a suitable silicone based grease.

5. Connect the flue to the boiler, positioning the seals correctly. Seal the flue into the wall with silicone or sand & cement a and cover with wall seals provided.

Flue seals should be lubricated with a silicone type grease to prevent damage (grease not supplied)

Vertical Outlet
The total length in equivalent metres of the concentric flue must not exceed the maximum lengths stated in the following table, note that each bend gives rise to the stated reduction. For example, a duct = 60/100 composed of 1 bend of 90° + 1 horizontal metre + 2 bends of 45° + 1 horizontal metre has a total equivalent length of 4 metres.

Connection with 80 mm pipe system

The unit can be connected to a system of separate air/flue pipes for a horizontal or vertical outlet as shown on the fig. 11-12. Numerous accessories are available on request to meet the various installation requirements.

Please refer to the flue manual catalogue or the price list for additional components.

To check you do not exceed the maximum permissible flue length, it is necessary to make a simple calculation before installation:

1. For each component, tables 4 - 5 (page 20) provide an "equivalent loss in metres", depending on the position of installation of the component (with air intake or flue extraction, vertical or horizontal).
   The loss is called "equivalent length" since it is compared to the loss of one metre of flue (defined as equal to 1). For example, a bend at 90° of 80 in flue run has an equivalent loss of 2.5 linear metres, i.e. it has a loss equal to that of 2.5 metres of flue length.
2. After designing the layout of the system, add up the losses in equivalent metres, depending on the installation position, of all the components and accessories in the system.
3. Check that the total calculated loss is less than or equal to 48 equivalent metres, i.e. the maximum permissible for this model of boiler.

For complete flue options please contact FERROLI or check our comprehensive flue manual.

Terminal Position

Statutory minimum distances for terminal siting

A - minimum distance 600mm - may be a nuisance if it 'wets' opposite boundary, crosses main pathway or condensate can drip on pathway.

B - minimum distance 600mm - may be a nuisance as plume could obscure window.

C - minimum distance 600mm - may be a nuisance if plumecrosses door.

The plume should not cross:

• a frequently used access route;
• any frequently used area (such as a patio or car parking space);
  • a neighbouring dwelling.

Nor should it be directed towards a window or door, or be sited close to a facing wali or other surface.

There are also other aspects to consider when planning the flue terminal position.

• A free passage of air is needed at all times to aid plume dispersal - which may be difficult in sheltered locations.
• In cold weather, the condensate could cause a safety hazard if it freezes on pathways, or if it results in frost damage to surfaces.
• The plume could trigger infra-red security lighting if sited in the wrong place.
• Ensure terminals do not obscure security camera field of vision.
• The terminal guards must be able to resist corrosive properties of the condensate.

Minimum Dimensions of Flue Terminal Positions

A	Directly below an opening, air brick, opening windows, etc.	300mm
B	Above an opening, air brick, opening windows, etc.	300mm
C	Horizontally to an opening, air brick, opening windows, etc.	300mm
D	Below gutters, soil pipes or drain pipes	75mm
E	Below eaves	200mm
F	Below balconies or car port roof	200mm
G	From a vertical drain pipe or soil pipe	150mm
H	From an internal or external corner	100mm
I	Above ground roof or balcony level	300mm
J	From a surface facing the terminal	600mm
K	From a terminal facing the terminal	1200mm
L	From an opening in the car port (e.g. door, window) into the dwelling	1200mm
M	Vertically from a terminal on the same wall	1500mm
N	Horizontally from a terminal on the same wall	300mm
O	From the wall on which the terminal is mounted	N/A
P	From a vertical structure on the roof	150mm
Q	Above intersection with roof	300mm

NOTE

N/A = Not applicable

In addition, the terminal must not be nearer than 300mm to an opening in the building fabric formed for the purpose of accommodating a built-in element such as a window frame.

Condensing Terminal Positions: If the flue is to be terminated at low level, then the potential effect of the plume must be considered.

The plume should not be directed:

• across a frequently used access route
• towards a window or door
• across a neighbouring property

Connection to collective flues or single flues with natural draught

If you are then going to connect the DOMIcompact F 30 B boiler to a collective flue or a single flue with natural draught, the flue must be expressly designed by professionally qualified technical personnel in conformity with the standards and rules in force.

In particular, flues must have the following characteristics:

• Be sized according to the method of calculation stated in the standard
• Be airtight to the products of combustion, resistant to the fumes and heat and waterproof for the condensate
• Have a circular or square cross-section (some hydraulically equivalent sections are permissible), with a vertical progression and with no restrictions
• Have the ducts conveying the hot fumes adequately distanced or isolated from combustible materials
• Be connected to just one unit per floor, for at most 6 units in all (8 if there is a compensation duct or opening)
• Have no mechanical suction devices in the main ducts
• Be at a lower pressure, all along their length, under conditions of stationary operation
• Have at their base a collection chamber for solid materials or condensation of at least 0.5 m, equipped with a metal door with an airtight closure.

2.7 Condensate outlet connection

fig. 13

The boiler is equipped with an internal siphon-trap to drain off the condensate. Fit the inspection bowl A and the hose B, pushing it on for approximately 3 cm.

Fill the siphon-trap with approximately 0.5 l. of water and connect the hose to the waste system or soakaway

Condensate discharge

Where possible the condensate should discharge into an internal soil pipe or waste system. The minimum pipe diameter required is 22 mm, a trap has already been fitted to the appliance with a flexible hose to facilitate the connection to the condensate discharge pipe.

The pipe should be a solvent weld plastic, not copper, as the condensate has a ph value of 4 (slightly acidic).

Where it is not possible to terminate internally, the condensate discharge pipe may be run outside (see below drawing).

Any external run is subject to freezing, in severe weather conditions. To avoid this the pipework should be installed to dispose of the condensate quickly, with as much as possible run internally, before passing through the wall.

Pipework external to the building should be increased in diameter to 32 or 40 mm solvent weld. It should be run to a external drain or soakaway, with a maximum length of 3 metres.

If a soakaway (condensate absorption point) is used, it should be constructed as shown below.

The gradient of the discharge pipe should be 2.5° (45 mm/m) minimum.

fig. 14

3. SERVICE AND MAINTENANCE

3.1 Adjustments

All adjustment and conversion operations must be carried out by a Qualified and trained engineer such as a Ferroli service engineer.

FERROLI S.p.A. declines any responsibility for damage or physical injury caused by unqualified and unauthorised persons tampering with the device.

Gas supply conversion

The unit can function with either Natural Gas or LPG and is factory-set for use with one of the two gases, as clearly shown on the packing and on the unit's dataplate. Whenever a different gas to that for which the unit is preset has to be used, a conversion kit will be required, proceeding as follows:

1. Replace the injectors at the main burner, by inserting the injectors specified in the technical data table in chap. 4, according to the type of gas used
2. Adjust the burner minimum and maximum pressures (ref. relevant paragraph), setting the values given in the technical data chart for the type of gas used.

3. How to adjust the parameter for the specific type of gas to be used:

4. turn the boiler onto standby

5. press the RESET button for 10 seconds
6. P1 will appear on the display
7. press the RESET button for 5 seconds
8. turn the hot water knob (ref. 2 - fig 1) onto "0" (for Natural Gas operation) or onto "1" (for LPG operation)
9. press the RESET button for 5 seconds
10. P2 will appear on the display
11. turn the heating knob (ref. 1 - fig 1) onto minimum and then onto maximum
12. the boiler will go back onto standby

13. turn the heating & hot water knobs onto the set temperatures.

14. Attach the sticker contained in the conversion kit, near the dataplate as proof of the conversion.

Turning on TEST mode

To turn on TEST mode, press the multi-function button 3 times in 3 seconds.

The display will show the radiator and hot water symbols flashing, the current heating power, the ECO symbol (if ECONOMY mode is on) and the flame symbol.

To quit TEST mode, press the multi-function button 3 times in 3 seconds.

TEST mode turns off automatically after 15 minutes.

Adjusting burner pressure

Since this unit has flame modulation, there are two fixed pressure settings: the minimum and maximum, which must be as stated in the technical data chart according to the type of gas.

• Connect a suitable pressure gauge to pressure point "B" downstream from the gas valve having loosened it first.
• Disconnect the pressure compensation tube "H".
  • Take off the protective cap "D".
• Run the boiler in TEST mode (press the multi-function button 3 times in 3 seconds): - TEST mode on: turn the heating knob (ref. 1 - fig 1) onto maximum.
• Adjust the maximum pressure with the screw "G", clockwise to increase it and anticlockwise to decrease it.
• Disconnect one of the two electrical connectors from the moduleg "C" on the gas valve.
• Adjust the minimum pressure with the screw "E", clockwise to decrease it and anticlockwise to increase it.
• Reconnect the electrical connector disconnected from the modureg on the gas valve.
• Check that the maximum pressure has not changed.
• Reconnect the pressure compensation tube "H".
• Put the protective cap "D" back on.
• To end TEST mode, repeat the sequence for turning it on or wait 15 minutes.

G Maximum pressure adjustment

Having disturbed test point 'B' when checking or adjusting the gas pressures, it is considered mandatory to check for gas leaks using a suitable leak detection fluid or sniffer at that connection.

Adjusting the maximum heating output

To adjust the heating power, set the boiler on TEST operation (see par. 3.1). Turn the heating temperature control knob (ref. 1 - Fig. 1) clockwise to increase the power or anticlockwise to decrease it (see pressure/power diagram Fig. 21). The display shows the power setting from 0 to 99%. Exit TEST operation (see par. 3.1). The maximum heating power will remain as set during the TEST mode. (100% output shown as 99% due to the display only being 2 digits).

Ignition power adjustment

To adjust the ignition power, set the boiler on TEST operation (see par. 3.1).

Turn the hot water temperature control knob (ref. 3 - Fig. 1) clockwise to increase the power or anticlockwise to decrease it (see pressure/power diagram Fig. 21). The display shows the power setting from 0 to 60%. Exit TEST operation (see par. 3.1). The ignition power will remain as set during the TEST mode.

NOTE Recommended ignition pressure for standard 100mm concentric flueing is 30%.

3.2 Initial start-up

Commissioning must be performed by Qualified Personnel only!.

Checks to be made at initial start up, and after all maintenance operations that involved disconnecting from the system or an intervention of a safety device.

Before lighting the boiler:

• Open any isolation valves between the boiler and the systems.
• Check the soundness of the gas system, proceeding with caution and using a suitable leak detection fluid to detect any leaks in connections.
• Fill the water system and make sure that all air contained in the boiler and the system has been vented by opening the air vent valve on the boiler and any vent valves on the system.
• Make sure there are no water leaks in the system, hot water circuits, connections or boiler.
• Make sure the electrical supply is properly connected.
• Make sure that the unit is connected to a good earthing system.
• Make sure that there is sufficient gas available to produce safe combustion. (min inlet working pressure = 20mbar)
• Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler.

Lighting the boiler

• Open the gas isolation valve on the boiler.
• Purge the air from the gas pipe work to the boiler.
• Switch on the electrical supply to the boiler.
• Turn knob "1" (Fig. 1) onto Winter in correspondence with a value greater than 50°C and the room thermostat knob, if applicable, onto the desired temperature setting. At this point, the burner will light and the boiler begins to function automatically, controlled by its software and safety devices.
  If, after correctly carrying out the lighting procedure, the burners do not light and fault F1 is generated, press the RESET button for 1 second and release it. The software will repeat the ignition cycle in the next 30 seconds. If the burners do not light after the second attempt, consult the "Troubleshooting" paragraph.
  In case of an electrical power failure while the boiler is working, the burners will go out and re-ignite automatically when power is restored.

Checks during operation

• Check the soundness of the gas circuit and water systems.
• Check the efficiency of the flue and air-flue ducts while the boiler is working.
• Check that the water is circulating properly between the boiler and the systems.
• Make sure that the gas valve modulates correctly in both the heating and hot water production modes.
• Check the proper ignition of the boiler by performing various tests, turning it on and off with the room thermostat or remote control.
• Make sure that the gas consumption indicated on the meter corresponds to that given in the technical data table in chap. 4. (Input rating)
• Check there is the right flow rate of hot water with the Δt stated in the chart: The measurement should be made with specific instruments and as close as possible to the boiler, also considering the heat lost from the pipework.
• Make sure that with no call for heating the burner correctly ignites on opening a hot water tap. Check that during heating operation, on opening a hot water tap, the heating pump stops and there is a regular production of hot water.
• Check the parameters are programmed correctly and perform any required customization (power, temperatures, etc.)

Turning off

Turn the knobs (ref. 1 and 2 Fig. 1) onto minimum.

When the boiler is turned off, the printed circuit board is still powered.

Hot water and heating operation are disabled, the display shows but the frost protection mode remains active.

The frost protection system will not work if the electricity and/or gas supply to the unit are cut off.

To avoid damage caused by freezing during long shutdowns in winter, it is advisable to drain all water from the boiler, the tap water and the system water; or drain off just the tap water and add a suitable antifreeze to the heating system, as prescribed in chap. 2.3.

3.3 Maintenance

The following operations must only be carried out by suitably trained and qualified personnel, such as Ferroli service engineers.

Seasonal inspection of the boiler and flue

It is advisable to carry out the following checks at least once a year:

• The control and safety devices (gas valve, flow meter, thermostats, etc.) must function correctly.
• The air-flue terminal and ducts must be free of obstructions and leaks.
• The gas and water systems must be airtight.
• The burner and exchanger must be clean. Follow the instructions in the next paragraph.
• The electrode must be free of debris and properly positioned.
• The water pressure in the cold water system must be about 1 bar; otherwise, bring it to that value.
• The expansion tank must be filled with air at 1 bar.
• The gas flow and pressure must correspond to that given in the respective tables.
• The circulation pump must be manually spun, vented and not be restricted.
• The condensate discharge must be clean, free of obstructions and leaks and the sediment bowl cleaned out.

Opening the casing

To open the boiler casing:

1 Unscrew the two screws A
2 Lower the instrument panel
3 Drop down the instrument panel
4 Fully unscrew the two screws B
5 Raise and remove the casing C

Before carrying out any operation inside the boiler, disconnect the electrical power supply and isolate the gas supply.

Cleaning the boiler and burner

The body and burner must not be cleaned with chemical products or wire brushes. Special care must be taken over all the sealing systems pertaining to the sealed chamber (gaskets, cable clamps, etc.). After performing all these operations, check and carry out all the phases of ignition and thermostat operation, the gas valve and circulation pump.

After these checks, make sure there are no gas leaks.

Combustion analyser testing

It is possible to analyse the combustion through the air and flue sampling points shown in fig. 17. To make the measurement, it is necessary to:

1) Open the flue sampling point
2) Insert the probe;
3) Turn on the hot water tap;
4) Turn the domestic hot water stat to maximum;
5) Allow the boiler to reach thermal equilibrium (10 - 15 min.);
6) Wait 10 minutes for the boiler to stabilize
7) Take the measurement.

fig. 17

3.4 Troubleshooting

Fault Diagnosis

The boiler is equipped with an advanced self-diagnosis system. In the event of trouble with the boiler, the display will show the relevant code.

There are faults that cause shutdown (faults from F1 to F3): in order to restore operation it requires the operator to press RESET for 1 second (ref. 2 - Fig. 1) or RESET on the optional remote timer control if this is installed; if the boiler fails to start, it is necessary to resolve the fault indicated on the display.

Other faults (from F5 to F37) cause temporary shutdowns that are automatically reset as soon as the value comes back within the boiler's normal working range.

Fault	Display code	Possible cause	Cure
