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.
