1. OPERATING INSTRUCTIONS
1.1 Introduction
Dear Customer, Thank you for choosing DOMIcompact F 24 D, 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.
DOMIcompact F 24 D is a high-efficiency 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 and burner equipped with electronic ignition and ionization flame control.
The boiler is totally room sealed from the installation room: the air required for combustion is drawn from outside. The boiler also includes a fan, modulating gas valve, pump, expansion vessel, flow switch, safety valve, temperature sensors, a safety thermostat and a low 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 combined with the room thermostat (not supplied) 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 are immediately signalled by the display and, if possible, corrected automatically.

1.3 Turning on and off
Ignition
• Open the gas isolation valve on the boiler.
• Purge the air from the pipe work to the gas valve.
• Turn on the 3amp electrical switch or insert the plug to the boiler.
• Turn the heating and hot water control knobs onto their required temperatures (see par. 1.4).
• The boiler is now ready to function automatically whenever hot water is drawn or both the time clock and room thermostat call for heating.
Turning off
Turn the knobs (ref. 1 and 2 Fig. 1) onto minimum. If the boiler is turned off this way, then the P.C.B is still powe-
red. Hot water and heating operation are disabled, the display shows
; but the frost protection function remains active
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 has priority over the heating only time 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.
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 to the optional remote open therm control, the above adjustments (system and hot water temperature) can only 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 comfort mode is active the water in the boiler is maintained at a pre­determined temperature, which means that hot water is available at the boiler outlet as soon as a tap is opened, ie 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 flash 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).

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

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 efficient operation and long life of the boiler, the plumbing system must be well designed and always complete with all those accessories that guarantee regular operation and running, ie room thermostat, trv’s and automatic bypass etc .
If the flow and return pipes follow a path where air pockets could form in certain places, it is esential to install air vent valves at these points. Also, install a type “A” drain cocks at the lowest point s in the system to allow its complete draining. when required 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 requied through the heat exchanger, it is therefore essential to fit an automatic by-pass a min of 3 metres away from the appliance, This should be 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 efficient operation (BS 7593 Building regs Doc L).
Make the connections to the appliance as shown in 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 allow safe discharge to the outside ground in the event of over-pressure in the heating circuit. If this is not done, and the drain valve opens and floods the room, the boiler manufacturer is not to be held responsible. The pipework must have a continuous fall from the boiler, 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 pipework is 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 meters from boiler).

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 pro-
pane. Do not use pipes of a smaller diameter 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 pipework must be adquately supported. An isolating gas valve is provided and must be fitted on the boiler gas inlet. Please wait 10 minutes when lighting from cold before checking the gas rate, this will 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.
The unit’s electrical safety is only guaranteed when correctly connected to an efficient earthing system installed according to current safety standards and checked by a professionally qualified person . The manufacturer is not responsible for any damage caused by failure to earth the system. Also make sure that the electrical system is adequate for the maximum power absorbed by the unit, as specified on the boiler dataplate, in particular ensuring that the crossectional area of the
electrical cables are suitable for the power absorbed by the unit . The boiler is prewired and provided with a cable for connection to the electrical supply The prewired cable must be connected to the supply with a permanent connection and equipped with a double pole switch which contacts have a minimum opening of at least 3 mm, and fused at max. 3A between the boiler and the line. It is important to check the polarities (LIVE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) and ensure they are correctly connected to the corresponding terminals on the electrical supply .
The user must never change the boilers power cable. If the cable gets damaged, switch off the unit
and have it changed only by professionally qualified personnel. If changing the electric power cable,
use only “HAR H05 VV-F” 3x0.75 mm2 cable with a maximum outside diameter of 8 mm.

To check you do not exceed the maximum per­missible duct length, it is necessary to make a simple calculation before installation:
1. For each component, the tables provide an “equivalent load loss in linear metres”, depen­ding on the position of installation of the com­ponent (with air suction or fume extraction, vertical or horizontal).
The loss is called “equivalent in linear metres”
since it is compared to the loss of one metre of duct in air suction (defined as equal to 1). For example, a bend at 90° of Ø80 in fume extraction has an equivalent loss of 2.5 linear metres, i.e. it has a loss equal to that of 2.5 linear metres of duct in air suction.
2. After completely defining the layout of the system of split flues, 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 maxi- mum permissible for this model of boiler.
If the chosen flue system exceeds the maximum permissible limit, it is recom­mended to use ducts with a larger dia­meter for some sections.

Connection to collective flues or single flues with natural draught
The UNI 10641 standard prescribes the design criteria and checking the internal dimensions of the collective flues and single flues with natural draught for units with a sealed chamber equipped with a fan in the combustion circuit.
If you are then going to connect the Domicompact F 24 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 UNI 10641 standard.
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 quadrangular cross-section (some hydraulically equivalent sections are permissible), with a vertical progression and with no constrictions
• 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.

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 those specified in the technical data table in chart. 4, according to the type of gas used
2. Adjust the burner minimum and maximum pressures (ref.to page 33), 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:
- turn the boiler onto standby
- press the RESET button for 10 seconds
- P1 will appear on the display
- press the RESET button for 5 seconds
- turn the hot water knob (ref. 2 - fig 1) onto “0” (for Natural Gas operation) or onto “1” (for LPG operation)
- press the RESET button for 5 seconds
- P2 will appear on the display
- turn the heating knob (ref. 1 - fig 1) onto minimum and then onto maximum
- the boiler will go back onto standby
- turn the heating & hot water knobs onto the set temperatures.
4. Attach the sticker contained in the conversion kit, near the dataplate, as proof of the conversion.
Turning on TEST mode

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 modureg “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
• Shut down the boiler
• Remove the pressure gauge
• Re-seal test point ‘B’
• Re-light the boiler and check for gas leaks using a suitable “Leak detection fluid”

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
25
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. 20). 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 anti-
clockwise to decrease it (see pressure/power diagram Fig. 20). 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 Recomended ignition pressure for standard 100mm concentric horizontal 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.after completing a tightness test
• 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 correctly 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 control knob “1” (Fig. 1) onto Winter in correspondence with a value greater than 50 °C and ensure the room thermostat is calling, At this point, the burner will light and the boiler begins to function automatically, controlled by its software and safety devices.
If, after following 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.
26
In case of an electrical power failure while the boiler is working, the burners will go out and re­ignite 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 for correct 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 correct flow rate of hot water with the Δt stated in the technical data chart: The measurement should be made with specific instruments and as close as possible to the boiler, also con­sidering the heat lost from the pipe work.
• Make sure that with no call for heating the burner ignites correctly upon opening a hot water tap. Check that during heating operation, on opening a hot water tap, the heating pump stops and there is a con­stant production of hot water.
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 operations 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 boiler are cut off. To avoid damage caused by freezing during long shutdowns in winter, it is advisable to drain all water from the boiler, both tap 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 switch, 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 sound.
• The burner and exchanger must be clean. Follow the instructions in the next paragraph.
• The electrode must be free of debris and correctly positioned.
• The water pressure in the cold water system must be approximately 1 bar; otherwise, bring it to that value.
• The expansion tank must be filled with air @ 1bar.
• 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.

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 seals 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. 15.
To make the measurement, it is necessary to:
1) Insert the probes as far as the stop;
2) Open a hot water tap;
3) Adjust the hot water temperature to maxi-
mum.
4) Wait 10-15 minutes for the boiler to stabilize*
5) Take the measurement.
Analyses made with an unstabilized boiler can cause measurement errors.
