nel, according to current regulations and the manufacturer's instructions. Do not car-
ry out any operation on the sealed control parts.
•
Incorrect installation or inadequate maintenance can result in damage or injury. The
Manufacturer declines any liability for damage due to errors in installation and use
or failure to follow the instructions.
•
Before carrying out any cleaning or maintenance operation, disconnect the unit from
the power supply using the system switch and/or the special cut-off devices.
•
In case of a fault and/or poor operation, deactivate the unit and do not attempt to
repair it or directly intervene. Contact professionally qualified personnel. Repair/re-
placement of the products must only be carried out by professionally qualified using
original spare parts. Failure to comply with the above could affect the safety of the
unit.
•
This unit must only be used for its intended purpose. Any other use is considered
improper and therefore dangerous.
•
The packing materials are potentially hazardous and must not be left within the
reach of children.

The images given in this manual are a simplified representation of the product. In
this representation there may be slight and insignificant differences with respect to
the product supplied.
2. OPERATING INSTRUCTIONS
2.1 Introduction
Dear Customer,
Thank you for choosing a
FERROLI
boiler featuring advanced design, cutting-edge
technology, high reliability and quality construction. Please read this manual carefully
since it provides important information on safe installation, use and maintenance.
ATLAS
is a high-efficiency heat generator for the production of heating hot water, suita-
ble for operation with blown oil or gas burners. The boiler shell consists of cast iron ele-
ments, assembled with steel stays and double cones, whose profile is specially designed
with optimum division of the fins, offering high thermal efficiency and therefore high en-
ergy-saving.

2.3 Turning on and off
Boiler lighting
Open the fuel shutoff valves.
Switch on the power to the unit.
Press button 2 of fig. 1 to feed the boiler and burner. Refer to the burner manual for op-
eration.
Turning the boiler off
For brief shutdown periods just press button 2 of fig. 1 on the control panel , bringing it
to position “0”. For long shutdown periods, as well as operating button 2 also close the
fuel shutoff valve . To avoid damage caused by freezing during long shutdowns in winter,
add a suitable antifreeze to the system or completely drain the system.
2.4 Adjustments
Heating temperature setting
Set the required system temperature with the control thermostat 4 of fig. 1.
For the model
ATLAS 95
, with the control thermostat
5
then set the temperature of the
2nd stage to a temperature 10°C
lower than that of the 1st stage
.
A
IMPORTANT: The temperature setting of the 2nd stage must always be
lower than that of the 1st stage.

Room temperature adjustment (with optional room thermostat)
Using the room thermostat, set the temperature desired in the rooms. If the room ther-
mostat is not installed the boiler will keep the heating system at its setpoint temperature.
3. INSTALLATION
3.1 General Instructions
BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSON-
NEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL
MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF NA-
TIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.
3.2 Place of installation
The boiler must be installed in a special room with ventilation openings towards the out-
side in conformity with current regulations. If there are several burners or extraction units
that can work together in the same room, the ventilation openings must be sized for si-
multaneous operation of all the units. The place of installation must be free of flammable
objects or materials, corrosive gases, volatile substances or dusts which, sucked by the
burner fan, can obstruct the pipes inside the burner or the combustion head. The room
must be dry and not exposed to rain, snow or frost.
A
If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
vided for removing the casing and for normal maintenance operations. In par-
ticular, after boiler installation with burner on the front door, make sure the front
door can open freely without the burner striking walls or other obstacles.
3.3 Plumbing connections
The heating capacity of the unit must be previously established by calculating the build-
ing's heat requirement according to the current regulations. The system must be provid-
ed with all the components for correct and regular operation. It is advisable to install
shutoff valves between the boiler and heating system allowing the boiler to be isolated
from the system if necessary.
B
The safety valve outlet must be connected to a funnel or collection pipe to pre-
vent water spurting onto the floor in case of overpressure in the heating circuit.
Otherwise, if the discharge valve cuts in and floods the room, the boiler manu-
facturer cannot be held liable.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the pipes of the system to remove any residuals or
impurities that could affect proper operation of the unit.
Carry out the relevant connections according to the diagram in and thecap. 5 symbols
given on the unit.
A
The unit is not supplied with an expansion tank; its connection must therefore
be carried out by the Installer. The pressure in the system, when cold, must be
1 bar.
Water system characteristics
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO3), use suitably treated
water in order to avoid possible scaling in the boiler. Treatment must not reduce the hard-
ness to values below 15°F (Decree 236/88 for uses of water intended for human con-
sumption). Treatment of the water used is indispensable in case of very large systems
or with frequent introduction of replenishing water in the system.
B
If water softeners are installed at the boiler cold water inlet, make sure not to
reduce the water hardness too much, as this could cause early deterioration of
the magnesium anode in the hot water tank.
Antifreeze system, antifreeze fluids, additives and inhibitors
If it becomes necessary, it is permissible to use antifreeze fluid, additives and inhibitors
only if the manufacturer of these fluids or additives guarantees they are suitable for this
use and cause no damage to the heat exchanger or other components and/or materials
of the boiler unit and system. It is prohibited to use generic antifreeze fluid, additives or
inhibitors that are not expressly suited for use in heating systems and compatible with
the materials of the boiler unit and system.
3.4 Burner connection
An oil or gas burner, with blown air for pressured furnaces, can be used if its operation
characteristics are suitable for the size of the boiler furnace and its overpressure. The
choice of burner must be made beforehand, following the manufacturer's instructions,
according to the work range, fuel consumption and pressures, as well as the length of
the firebox. Install the burner in compliance with the Manufacturer's instructions.
