2. INSTALLATION
General instructions
This appliance must only be used for the purposes it has been specifically designed for. This appliance is used to heat water to below-boiling
temperatures at atmospheric pressure, and must be connected to a heating and/or domestic hot water distribution system, according to its
characteristics, performance and heating capacity. All other uses are considered improper.
THEBOILERMUSTONLYBEINSTALLEDBY QUALIFIEDANDSPECIALISTPERSONNEL,INCOMPLETE COMPLIANCE WITHALLTHE
INSTRUCTIONS REPORTED IN THIS TECHNICAL MANUAL, THE LEGAL STANDARDS IN FORCE, THE PRESCRIPTIONS OF ANY
NATIONAL AND LOCAL STANDARDS, AND ACCORDING TO THE RULES OF GOOD PRACTICE.
Incorrect installation may cause damage to people, animals and things. The manufacturer will not be held liable in such events.
Place of installation
The room in which the boiler is installed must have ventilation openings to the outside according to the standards in force. If the same room
features a series of burners or exhaust devices that can operate at the same time, the ventilation openings must be large enough for the
simultaneous operation of all the appliances.
The place of installation must be free of flammable objects or materials, corrosive gas, dust or volatile substances that, sucked in by the
burner’s fan, may block the internal tubing of the burner or the combustion head. The environment must be dry and not exposed to rain, snow
or frost.
Positioning the boiler
The minimum spaces shown in the figure must be complied with. Specifically, make sure that after
assembling the boiler with the burner on the front door, the latter can be opened without the burner
hittingagainst the wall orany other boiler. Leave a free space of at least100mm on the sidethat the door
swings towards.

2.1 Water connections
Make the water connections to the appliance according to the indications shown both next to each fitting and in Figure 2 of this booklet.
The connections must be made in such a way that the pipes are not under stress. The safety valve must be fitted in the central heating circuit,
as close as possible to the boiler, without there being any obstructions or on-off devices between the boiler and the valve.
The appliance is not supplied with an expansion vessel, and therefore such device must be connected by the installer. Please note that in this
regard, the pressure in the system, when cold, must be between 0.5 and 1 bar.
2.2 Connecting the burner
Oil or gas jet burners for pressurised furnaces can be used if their operating characteristics are suitable for the dimensions of the boiler’s
furnaceand its over-pressurevalue.The burner must bechosen following the instructionsprovidedbythe manufacturer, accordingto the field
of operation, fuel consumption and pressure, as well as the length of the combustion chamber.
Fit the burner following the instructions provided by the manufacturer of the device.
2.3 Electrical connections
The boiler should be connected to a single-phase, 230 Volt-50 Hz electrical line, using a permanent connection, installing a double
pole switch with contact openings of at least 3mm, and suitable fuses. Connect the burner and the room thermostat (if featured) as
shown in the wiring diagram in Chap. 4.
The electrical safety of the appliance is ensured only when the appliance is correctly connected to an effective earth system, as prescribed by
thesafety standards inforce.Have professionally qualifiedpersonnel check theefficiency and therating of the earth system.The manufacturer
isnot liable for any damage causedby the appliance not being correctlyearthed. In addition, make sure thatthe electrical system is adequately
rated for the maximum power absorbed by the appliance, indicated on the rating plate, and in particular that the cross-section of the wires is
suitable for the power absorbed by the appliance.
2.4 Flue connections
Theboiler should be connected to a suitable flue,manufactured in compliance with the standards in force. Thepipe between boiler and the flue
mustbe made from materialsuitable for this purpose,that is, resistant to both high temperatures and corrosion. The joints shouldbe carefully
sealed and the entire length of the pipe between the boiler and the flue should be thermally insulated, to avoid the formation of condensate.
2.5 Assembling the boiler
The boiler may be supplied:
1. As a set of elements, in 4 separate boxes, containing the Casing, Control panel, Elements, and accessories for assembling the elements.
Followthe instructions enclosed with the setof elements to assemble the boilerbody.Follow the instructions below toassemble the casing
and control panel.
2. With the body already assembled, in 3 separate boxes containing the Casing, Control panel and Boiler body.
Follow the instructions below to assemble the casing and the control panel.
AIf the boiler body is supplied already
assembled and is delivered from the
factory on a pallet, remove the bolts
1that fasten it to the pallet and
position it for final installation. Then
assemble the various panels.

in force.
FERROLI S.p.A. declines all liability for damage to persons and/or things deriving from the tampering with the appliance by unqualified or
unauthorised persons.
Before performing any cleaning or maintenance operations, disconnect the appliance from the mains power supply using the system switch
and/or the special on-off devices.
3.1 Commissioning
Checksto be performed on firstignition, and afterall maintenance operations that involve the disconnectionof the appliancefrom the systems
or intervention on the safety devices or parts of the boiler:
Before first ignition
Before igniting the boiler for the first time, check that:
athe system is filled at the right pressure and any air has been correctly vented;
bthere are no water or fuel leaks;
cthe electrical power supply is correct;
dall the flues have been installed correctly and not too near to or across any flammable parts;
ethere are no flammable substances near the appliance;
fthe burner is suitably sized for the output of boiler;
gthe water on-off valves are open.
First ignition
After having carried out the preliminary checks, the following ignition operations can be performed:
1Open the fuel on-off valve.
2Set the thermostat 4 (Fig. 1) to the desired value.
3Close the switch upstream from the boiler and switch 5 (Fig. 1) on the control panel.
At this stage, the burner will be ignited and the boiler will start operation.
After first ignition
After first ignition, check that:
1The door of the burner and smokebox are well sealed.
2Theburner isworking correctly.This checkshould beperformedusing the required instruments,following themanufacturer’sinstructions.
3The thermostats are working correctly.
4Water is circulating in the system.
5The flue gas is completely expelled through the flue.
3.2 Adjustments
Adjusting the burner
The efficiency and correct operation of the boiler depend above all on accuracy of the adjustments made to the burner.
Carefully follow the instructions provided by the manufacturer. Two-stage burners must have the first stage adjusted to an output that is no
lower than the minimum rated output of the boiler. The output of the second stage must not be greater than the maximum rated output of the
boiler.
3.3 Shut-down
For brief periods of inactivity, simply use switch 5 (Fig. 1) on the control panel.
For extended periods of inactivity, as well as operating switch 5, the fuel on-off valve must also be closed.
3.4 Maintenance
To ensurethe maximumreliability of theheating system andminimum runningcosts, the boilermust be cleaned regularly,at leastoncea year.
These maintenance operations must be performed by qualified and specialist personnel.
Cleaning the boiler
1Disconnect the power supply to the boiler
2Remove the upper and lower front panel.
3Open the door by unscrewing the knobs.
4Clean the inside of the boiler and the entire flue gas discharge path, using a brush or compressed air.
5Close the door again, and fasten it using the knob.
To clean the burner, refer to the instructions provided by the manufacturer.
