1. OPERATING INSTRUCTIONS

1.1 Introduction

Dear Customer,
Thank you for choosing DOMIcompact F 30 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 30 D is a high-efficiency non 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 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 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 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.

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).

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

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 some anomalies that can be caused by simple, user-solvable problems.
If the problem remains after two attempts at resetting, contact the Ferroli Service Centre.
For other faults, refer to section 3.4 “Troubleshooting”.

Fault CureDisplay code

Make sure that the gas cocks ahead of the boiler and on the
meter are open.

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

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 essential
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 bypass 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.

5 Heating system return Ø 3/4”

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 event 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 metres from boiler).

DOMIcompact F 30 D

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 cross-sectional 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 ca-

ble, use only “HAR H05 VV-F” 3x0.75 mm2 cable with a maximum outside diameter of 8 mm.

The total length in linear metres of the flue
pipe must not exceed the maximum lengths
stated in the following table, considering that
each bend gives rise to the stated reduction.
For example, a duct D= 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.

For the installation:

1. Define the position for installing the unit.

2. Drill the wall for the air/flue pipe outlet according
to the references stated in the figures, consi­dering that the horizontal sections of piping
must have a gradient of approximately 3 mm
per metre of length downwards to prevent any
rainwater getting into the boiler.

3. Make a hole of diameter 10 - 20 mm greater
than the nominal diameter of the flue pipe used
to facilitate insertion.

4. If necessary, cut the end pipe to size, considering
that the external pipe must protrude from the
wall by between 10 and 60 mm (Fig. 10a and
10b). Eliminate the cutting burrs.

5. Connect the ducts to the boiler, positioning
the gaskets correctly and seal the wall coupling
points with special sleeves.

Connection with two pipe
system

The unit can be connected to a
system of separate air/flue ducts
for a vertical or horizontal outlet
as shown on the drawings 11 - 12
alongside. Numerous accessories
are available on request to meet
the various installation require­ments. The components used most
frequently are stated in tables.
Please refer to the flue accessory
catalogue or the price list for addi­tional components.

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

DOMIcompact F 30 D

Flue

Air

1. For each component, tables pro­vide an “equivalent load loss in linear metres”, depending on
the position of installation of the component (with air inlet or
flue extraction, vertical or horizontal).

The loss is called “equivalent in linear metres” since it is compa-

red to the loss of one metre of duct in air inlet (defined as equal
to 1). For example, a bend at 90° of Ø80 in flue 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 inlet.

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 50
equivalent metres, i.e. the maximum permissible for this model
of boiler.

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 30 D 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, 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 flue gases 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 34), 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:

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 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 on Natural gas).

• 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.

DOMIcompact F 30 D

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
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.

Δt stated in the technical data chart: The

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 vessel 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 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 analysis

Two sampling points have been included in the boiler, one
for fumes and the other for air.

To take the samples:

1) Remove the boiler casing.

2) Open the air and fume sampling points on the sealed
chamber.

3) Insert the probes as far as the stop.

4) Open a hot water tap.

5) Adjust the hot water temperature to maximum.

6) Wait 10-15 minutes for the boiler to stabilize*.

7) Take the measurement.

Analyses made with an unstabilized boiler can cause
measurement errors.

3.4 Troubleshooting

Fault Diagnosis

The boiler is equipped with an advanced self-diagnosis system. In the event of a fault within 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) if the boiler fails to start, it will be 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.
