2. OPERATING INSTRUCTIONS
2.1 Introduction
Dear Customer,
Thank you for choosing PEGASUS 56 LN, a floor-standing boiler FERROLI featuring ad-
vanced design, cutting-edge technology, high reliability and quality construction. Please
read this manual carefully and keep it for future reference.
PEGASUS 56 LN is a high-efficiency heat generator for central heating using natural gas
or liquefied gas (configurable at the time of installation) and regulated by an advanced
electronic control system.
The boiler shell consists of cast-iron elements whose particular shape guarantees high
exchange efficiency under all operating conditions and an open-flue burner equipped
with electronic ignition and ionization flame control.
The boiler is also equipped with a temperature limiter (safety thermostat) and a fume
evacuation control device (fume thermostat).
Thanks to the electronic flame control and ignition system, boiler operation is mostly au-
tomatic.
The user only has to set the temperature required inside the home (by means of the op-
tional room thermostat, whose installation is recommended) or adjust the temperature of
the system.

2.3 Turning on and off
Lighting
•
Open the gas cock ahead of the boiler
•
Turn on the switch or insert the plug (if present) ahead of the boiler
•
Turn the main switch "6" to position 1 (fig. 49).
•
Turn the knob "5" to the selected temperature and that of the room thermostat (if
present) to the required temperature value. The burner will light and the boiler be-
gins to function automatically, controlled by its adjustment and safety devices.
•
If the boiler is equipped with an electronic thermostatic controller fitted in position 1
of fig. 49, the user must also take into account the manufacturer's instructions.
If the burners do not light and the pushbutton-shutdown indicator 4 comes on
A
after correctly carrying out the lighting procedures, wait about 15 seconds and
then press the above pushbutton. The reset controller will repeat the lighting cy-
cle. If the burners do not light even after several attempts, contact an authorised
service centre or qualified personnel.
Turning off
Close the gas cock ahead of the boiler, turn knob "6" to 0 and disconnect the power to
the unit.
B
To avoid damage caused by freezing during long idle periods in winter, it is ad-
visable to drain all water from the boiler and system; or add a suitable antifreeze
to the heating system.
The boiler switch 6 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 5 of fig. 49 clockwise to increase the heating water temperature, or anti-
clockwise to decrease the temperature. 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 required room temperature. Controlled by the room
thermostat, the boiler lights and brings the system water to the temperature set by boiler
control thermostat 5 of fig. 49. The generator turns off when the required temperature in
the rooms is reached.
If the room thermostat is not present, 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. 49,
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 Maintenance
The user must have the heating system serviced by qualified personnel at least once a
year and combustion checked at least every two years. Consult sec. 19.3 of this manual
for more information.
The boiler casing, panel and aesthetic parts can be cleaned with a damp soft cloth, if nec-
essary soaked in soapy water. Do not use abrasive detergents and solvents.
2.6 Faults
Given below are the faults that can be caused by simple user-solvable problems.
Before calling the After-Sales Service check if the problem is due to no gas or
A
electricity.
Symbol Faults
Boiler shutdown by the flame controller
Boiler shutdown due to insufficient system pressure (only
if a water pressure switch is installed)
6
7
Boiler shutdown due to insufficient evacuation of fumes
Cure
Make sure that the gas cocks ahead of the
boiler and on the meter are open.
Press the lit pushbutton-indicator.
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 fume thermostat cover and press
the button below.
In case of repeated boiler shutdowns contact
the nearest service centre.
