2. INSTALLATION
2.1 Introduction
Dear Customer,
Thank you for choosing PEGASUS F3 N 2S, a floor-standing boiler FERROLI featuring
advanced design, cutting-edge technology, high reliability and quality construction.
Please read this manual carefully and keep it for future reference.
PEGASUS F3 N 2S is a high-efficiency heat generator for central heating, using natural
gas or liquefied gas and regulated by an advanced electronic control system.
The boiler shell consists of cast-iron elements whose particular shape ensures high ex-
change efficiency in all operating conditions, and an open-flue burner equipped with
electronic ignition and ionisation flame control.
The boiler also has an automatic boiler air vent valve, a 2-stage control thermostat and
a safety thermostat.
Thanks to the electronic ignition and flame control system, unit operation is for the most
part automatic.
The user only has to set the system temperature by means of the control thermostat.

2.3 Lighting and turning off

Lighting
• Open the gas cock ahead of the boiler.
• Turn on or insert any switch or plug ahead of the boiler.
• Turn the boiler switch "7" to 1 (fig. 1).
• Turn the knob "6" to the required temperature and that of a possible room thermostat
to the required temperature value. The burner will light and the boiler begins to func-
tion automatically, controlled by its adjustment and safety devices.
• If the boiler is equipped with an electronic thermostatic controller fitted in position 1
of fig. 1, the user must also take into account the manufacturer's instructions.
If the burners do not light and the button-shutdown indicator 5 comes on after
A
correctly carrying out the lighting procedures, wait about 15 seconds and then
press the above-mentioned button. The flame controller reset in this way will
then repeat the lighting cycle. If the burners do not light after several attempts,
consult the faults section
In case of a power failure while the boiler is working, the burners will go out and
A
relight automatically when the power is restored.
Turning off
Close the gas cock ahead of the boiler, turn knob "7" to 0 and disconnect the power.
B
To avoid damage caused by freezing during long idle periods in winter, it is ad-
visable to drain all water from the boiler, DHW circuit and system; or add a suit-
able antifreeze to the heating system.
The boiler switch "7" has 3 positions "0-1-TEST"; the first two have the on-off
function, the third (unstable) must only be used for service and maintenance
purposes.
2.4 Adjustments
System temperature adjustment
Turn the knob 6 of fig. 1 clockwise to increase the heating water temperature, or anti-
clockwise to decrease it. The temperature can be varied from a minimum of 30°C to a
maximum of 90°C. However, it is advisable not to operate the boiler below 45°C.
Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature required in the rooms. By room thermo-
stat command, the boiler lights and brings the system water to the temperature set by
boiler control thermostat 6 of fig. 1. The generator goes off when the required tempera-
ture in the rooms is reached.
If the room thermostat is not installed the boiler will keep the system at the temperature
set by the boiler control thermostat.
Water system pressure adjustment
The filling pressure with system cold, read on the boiler water gauge detail 2 of fig. 1,
must be approx. 1.0 bar. If, during operation, the system pressure falls (due to the evap-
oration of gases dissolved in the water) to values below the minimum described above,
the user must bring it to the initial value by operating the filling cock. At the end of the
operation always close the filling cock.
2.5 Faults
Given below are the faults that can be caused by simple user-solvable problems.
Symbol Faults
Boiler shutdown by the flame control-
ler
Boiler shutdown due to insufficient
system pressure (only if a pressure
switch is installed in the system)
Boiler shutdown due to water over-
temperature

Before calling the after-sales service, check that the problem is not due to no
A
gas or power.
cod. 3540T624 - Rev. 02 - 11/2018
Cure
Check if the gas cocks ahead of the boiler and on the
meter are open.
Press the illuminated indicator-button.
In case of repeated boiler shutdowns, contact the nearest
service centre.
Fill the system to 1-1.5 bar cold by means of the system
filling cock.
Close the cock after use.
Unscrew the safety thermostat cover and press the but-
ton below.
In case of repeated shutdowns, contact the nearest serv-
ice centre.
