2. OPERATING INSTRUCTIONS
2.1 Introduction
Dear Customer,
Thank you for choosing PEGASUS 56, a floor-standing boiler FERROLI featuring advanced de-
sign, cutting-edge technology, high reliability and quality construction. Please read this manual
carefully and keep it for future reference.
PEGASUS 56 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 sys-
tem.
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 automatic.
The user only has to set the temperature required inside the home (by means of the optional 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. 1).
•
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 begins to function auto-
matically, 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.
A
If the burners do not light and the pushbutton-shutdown indicator 4 comes on after cor-
rectly carrying out the lighting procedures, wait about 15 seconds and then press the
above pushbutton. The reset controller will repeat the lighting cycle. If the burners do not
light even after several attempts, contact an authorised service centre or qualified per-
sonnel.
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 advisable to
drain all water from the boiler and system; or add a suitable antifreeze to the heating sys-
tem.
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. 1 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. 1. 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. 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 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. 4.3 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.
