1. OPERATING INSTRUCTIONS
1.1 Introduction
Dear Customer,
Thank you for choosing FERROLI 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.
FERROLI F 30 B is a high-efciency condensing appliance for heating and hot water production run-
ning on natural or liqueed petroleum gas (congurable 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 ue gases, and burner equipped with electronic ignition
and ionisation ame 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, ow meter, safety valve, temperature
sensors, a safety thermostat and a low system water pressure sensor.
Thanks to the microprocessor control and adjustment system with advanced self-diagnosis, unit ope-
ration is for the most part automatic. The power for heating is automatically governed by the control
system according to the indoor characteristics of the building and 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, 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.

1.2 Control panel
The boiler is designed for use with two types of gas: natural gas NG or propane (LPG). The type of
gas can be selected when purchasing the boiler or the appliance can be converted later on site by a
competent person. It operates with technologically advanced systems such as electronic control, safety
and control devices.
The boiler is tted with automatic electronic ignition so there is no pilot to worry about.

1.3 Operating instructions
Ignition
• Open the gas isolation valve upstream of the boiler.
• Purge the air from the pipe upstream of the gas valve.
• Ensure power is on to appliance.
• Turn the switch A (g. 1) to the ON position.
• The boiler is now ready to function automatically whenever hot water is drawn or the clock and room
thermostat calls for heating.
Turning off
Turn the switch A (g. 1) to the OFF position.
When the boiler is turned off with this button, the P.C.B. is no longer powered and the frost protection will
be disabled.
Close the gas isolation valve upstream of the boiler and disconnect the electrical power supply.
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.
1.4 Adjustments
Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature desired in the room. Controlled by the room thermostat,
the boiler lights and heats the system water to the set system setpoint temperature. The burner shuts
down when the desired temperature in the rooms is reached.
A room thermostat is a mandatory requirement (building regulations Doc “L” 2002).
C.H. temperature adjustment
To set the system ow temperature, use the C.H. control knob B (g. 1). Turning it
clockwise increases the temperature, turning it anticlockwise decreases it.
Domestic hot water temperature adjustment
To set the hot water temperature, use the D.H.W. control knob C (g. 1). Turning it
clockwise increases the temperature, turning it anticlockwise decreases it.
Hot Water Only - “SUMMER” ( )
To obtain hot water only from the boiler, turn switch (A g. 1) to the on position. The
top green light on the left side of the control panel is illuminated (power on ).
Turn the temperature regulator (B g. 1) to the position. Open a hot water tap, green light (tap
symbol) comes on, fan starts and burner will light. Indicated by ame symbol, green light coming on.
The temperature of the hot water can be adjusted by turning the hot water thermostat (C g. 1) clockwise
to increase and anti-clockwise to decrease the water temperature.

Heating and Hot Water - "WINTER” ( )
To obtain heating from the boiler, turn the temperature regulator (B g. 1) clockwise to the maximum
position, ensure that any other heating controls e.g. room thermostats, clock etc. are in the on posi-
tion.
The boiler may be in heating delay of three minutes as indicated by the green light ashing ( radiator symbol ). When
this light comes on all the time. The fan and pump will run and the burner will light indicated by the green ame
symbol light. Adjust the temperature regulator to the desired setting. (In winter do not run boiler below 50°C). If
a hot water tap is opened whilst the boiler is running for heating the pump will stop, suspending the heating phase
and the boiler will give priority to hot water production. When the tap is closed the boiler will go into a three minute
delay cycle before resuming for heating.
Frost Protection
In cold weather the boiler may appear to run when there is no demand for heating (i.e. clocks or room
thermostats turned off). This is due to the central heating sensor going into frost protection mode.
Once the boiler has reached 14°C or more it will close down until either the temperature again falls
below 7°C or the clock or room thermostat is turned on.
For this reason we recommend that the electricity to the boiler is left turned on. If you wish to turn off
the electricity to the boiler in winter you should drain completely the heating and hot water circuits.
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
Low system water pressure
Low system pressure will be indicated by ashing light on the right hand side of the facia illuminating (
bar
).
The boiler pressure gauge (D g. 1) should read at least 1 bar.
Boiler lock out
In the event of the red lockout light ( ) coming on, the on/off/reset switch (A g. 1) should be turned clockwise
against the spring tension to the reset position and released (this will put the boiler into three minute delay if in the
heating mode). Check gas supply or condensate discarge. Clean condensate discharge if dirty or obstructed. If the
lockout light ( ) illuminates repeatedly, contact an approved Férroli service engineer.
For other faults, refer to section 3.4 “Troubleshooting.”
Before calling the Ferroli service centre, check that the problem is not due to an installation
error or a problem with the gas/electricity or low water pressure in the system.

2.2 Boiler location
The unit’s combustion circuit is sealed off from the installation room. The installation room must be
sufciently 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 xing must ensure a stable and effective
support for the appliance, using the bracket and xings 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.
Drilling Template
Select suitable mounting position for boiler, using the template mark ue 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 (g. 3). Fix the wall bracket to the wall using standard lock nut (M8) on both sides. Mount
the boiler on the wall bracket and x using the special antitheft nut (M8) as described in the g. 3. Using a core drill
cut a 118mm diameter hole for the ue.

Make Up Water
Provision must be made for replacing water lost from the sealed system. Reference should be made
to BS6798, for methods of lling 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 supplied temporary lling loop is shown in g. 5. Ensure
the lling 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
tted as far as possible from the boiler
if thermostatic radiator valves are tted
thoughout.

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 regular
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 esential
to install 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 ow of 6 litres/min is requied through the heat exchanger, it is therefore essential to t 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 ush 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 g. 6.
Key
1 System ow (22 mm with isolation valve tted)
2 DHW outlet (15 mm with isolation valve tted)

4 Cold main inlet (15 mm with isolation valve tted)
5 System return - 22 mm with isolation valve tted (c/w lter)
6 System drain
7 Condense outlet
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 system water out onto the ground in the
event of over-pressure in the heating circuit. If this is not done, and the drain valve trips and oods 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 event of an over-pressurised
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).

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 without 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 tted 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 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 pipework must
be adquately supported. An isolating gas valve is provided and should be tted on the boiler gas inlet. Please
wait 10 minutes when lighting from cold before checking the gas rate. Gas pressures should be checked after
the boiler has operated for 10 minutes to ensure thermal equilibrium.
The connecting kits shown in g. 7 are supplied as standard.
2.5 Electrical Connections
The unit must be installed in conformity with current national and local regulations.
Connection to the electrical supply
The boiler must be connected to a single-phase, 230 Volt-50 Hz electric supply.
The unit’s electrical safety is only guaranteed when correctly connected to an efcient earthing system installed
according to current safety standards. Have the integrity of the earthing system checked by professionally
qualied personnel. 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 used by the unit, as specied
on the boiler dataplate, in particular ensuring that the cross section of the system’s cables is suitable for the
power used by the unit.
The boiler is prewired and provided with a cable for connection to the electricity supply. The connections to the
supply must be made with a permanent connection and equipped with a double pole switch whose 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 respect
the polarities (LIVE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) in making connections to
the electrical supply.
The user must never change the unit’s power cable. If the cable gets damaged, switch off the unit and have
it changed only by professionally qualied personnel. If changing the electric power cable, use solely “HAR
H05 VV-F” 3x0.75 mm2 cable with a maximum outside diameter of 8 mm.

Horizontal concentric ue installation
Horizontal ue installation
1. Dene the position for installing the unit.
2. When installing a horizontal ue 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 sillicone based grease.
5. Connect the ue to the boiler, positioning the seals correctly. Seal the ue into the wall with silicone or sand & cement

The total length in equivalent metres of the concentric
ue must not exceed the maximum lengths stated in the
following table, note that each bend gives an increase
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/ue pipes for a horizontal or vertical outlet as
shown on the g. 11 - 12. Numerous accessories are
available on request to meet the various installation
requirements.
Please refer to the ue manual catalogue or the
price list for additional components.
To check you do not exceed the maximum
permissible ue length, it is necessary to make
a simple calculation before installation:
1. For each component, tables 4 - 5 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 ue
(dened as equal to 1). For example, a bend
at 90° of Ø80 in ue run has an equivalent loss
of 2.5 linear metres, i.e. it has a loss equal to
that of 2.5 metres of ue 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 further flue options please contact
FERROLI or check our comprensive ue
manual.
