2.1 Introduction
Dear Customer,
Thank you for choosing PEGASUS 67 ÷ 107 2S, a floor-standing boilerFERROLI featur-
ing advanced design, cutting-edge technology , high reliability and quality construction.
Please read this manual carefully and keep it for future reference.
PEGASUS 67 ÷ 107 2S is a high-efficiency heat generator with low NOx emissions for
central heating, running on natural gas or liquefied gas, equipped with an advanced
electronic control system.
The boiler shell consists of cast-iron elements whose particular shape guarantees high
exchange efficiency in all operating conditions, and an open-flue burner equipped with
electronic ignition and ionisation flame control.
The boiler also has an automatic air vent valve, a 2-stage control thermostat and safety
thermostat.
Thanks to the electronic ignition and flame control system, boiler 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 the switch or plug ahead of the boiler.
• Turn the boiler switch "8" to 1 (fig. 1).
• Turn knob "7" to the selected temperature and any room thermostat to the required
temperature value. The burner will light and the boiler starts working automatically,
controlled by its adjustment and safety devices.
• If the boiler is equipped with an electronic thermostatic controller fitted in position
1fig. 1 of , the user must also take into account the manufacturer's instructions.
If the burners do not light and the shutdown button-indicator "6" comes on af-
A
ter correctly carrying out the lighting procedures, wait about 15seconds
and then press the above-mentioned button. The flame controller () reset in this
way will then repeat the ignition cycle. If the burners do not light even after sev-
eral 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 "8" to 0 and disconnect the power.
To avoid damage caused by freezing during
B
long shutdowns 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 8 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 7 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 required temperature in the rooms. By command of
the room thermostat, the boiler lights and brings the system water to the temperature set
by boiler adjustment thermostat 7 of fig. 1. The generator turns off when the required
temperature 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.
