1. OPERATING INSTRUCTIONS
1.1 Introduction
Dear Customer,
Thank you for having chosen the Tempra 30 O, an advanced-concept FERROLI wall-hung boiler featuring
cutting-edge technology, high reliability and constructional quality. Please carefully read this manual
and keep it for future reference.
The Tempra 30 O is a high efficiency heat generator for central heating systems, operating on natural
gas or LPG (the type of gas can be configured at the moment of installation) and managed by an advanced microprocessor-based control system.
The boiler body is made up of a copper heat exchanger, the special shape of which guarantees high
heat exchange efficiency in all operating conditions, and an atmospheric burner featuring electronic
ignition with ionisation flame control.
The boiler is intended for outdoor installation only.
The accessories supplied with the boiler also include a variable-speed pump, expansion vessel, safety
valve, air pressure switch, water pressure switch, temperature sensors and safety thermostat.
The microprocessor-based control system means that the operation of the appliance is almost comple-
tely automatic. The central heating output is automatically regulated by the control system according
to requirements. The domestic hot water output (with external storage installed) is automatically and
continuously controlled to ensure both comfort and economical operation.
The user simply has to set the temperature required inside the home (using the optional, yet recommended room thermostat) or set the system temperature and the required domestic hot water outlet
tem pe ra tu re. The regulation and control system will then ensure optimum operation all year round.
It MUST NOT be used for pool or spa heating.

1.3 Ignition and shut-down
Ignition
• Open the gas cock upstream of the boiler.
• Close or insert any switches or power plugs upstream of the boiler
• Place the main switch “A” in the ON position.
• Place knob “B” in the Winter position and set the room thermostat, if fitted, to the required temperature value. At this point, the burner will ignite and the boiler will start operating automatically,
managed by its control and safety devices.
If, after having correctly performed the ignition operations, the burners do not ignite and the
shut-down warning light is on, wait around 15 seconds, then turn knob A to the RESET position
and release it. The control unit will be reset and will repeat the ignition cycle. If, after a number
of attempts, the burners do not ignite, refer to the paragraph on troubleshooting.
Shut-down
Close the gas cock upstream of the boiler, turn knob “A” to OFF and disconnect the appliance from
the mains power supply.
When the boiler is off the boiler anti-freeze protection is not active.
For extended periods of inactivity during the winter months, in order to avoid damage due to
freezing, all the water should be drained from the boiler, both the domestic hot water and the
central heating system; alternatively, drain only the domestic hot water and place the special
antifreeze fluid in the central heating system.
1.4 Settings
Summer/Winter setting and system temperature control
With knob “B” Fig. 1 in the position of the symbol (Summer), the central heating function is deactivated.
Only the production of domestic hot water is activated (with the optional external hot water cylinder
installed).
With the knob “B” Fig. 1 in the position of the symbol
(Winter), both the central heating function
and domestic hot water are active.
Turning the knob clockwise increases the central heating water temperature, anticlockwise decreases
it. The temperature can be set from a minimum of 35° to a maximum of 85°. It is not recommended,
however, to operate the boiler below 45°.
Setting the ambient temperature (using the optional room thermostat)
Set, using the room thermostat or remote control, the temperature required inside the rooms. Based
on the command from the room thermostat, the boiler is ignited and heats the system water to the set
central heating outlet temperature. When the required temperature inside the rooms is reached, the
boiler switches off.
If no room thermostat or remote control is available, the boiler will maintain the system at the set central
heating outlet temperature.
Domestic hot water temperature control
Set the storage temperature, using knob “D” (supplied in the optional kit).

Before calling the service centre, check that the problem is not due to no gas or mains power
supply.
System water pressure control
The boiler is fitted with a cock for manually filling
the central heating system. The filling pressure when
the system is cold, as read on the boiler hydrometer,
must be around 1.0 bar.
If the pressure drops during operation (due to the
evaporation of the gas dissolved in the water) to a
value lower than the minimum described above, the
User must restore the initial value using the filling
cock. Once the operation is completed, always close
the filling cock.
1.5 Maintenance
It is recommended to have annual maintenance of the heating system performed by qualified personnel, and at least biennial checks on the combustion device. Please refer to Chap. 3.3 in this manual for
further information.
The casing, the control panel and the aesthetic parts of the boiler can be cleaned using a soft and damp
cloth, dipped in soapy water if necessary. Do not use abrasive detergents or solvents.
1.6 Troubleshooting
Any anomalies or operating faults are signalled by the LEDs on the control panel.
The following table lists the faults that may arise due to simple problems that can be resolved by the
user.

2. INSTALLATION
2.1 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 temperature at atmospheric pressure and must
be connected to a central heating and/or hot warm distribution system, according to its characteristics, performance and heating capacity. All other uses are considered improper.
THE APPLIANCE SHALL BE INSTALLED IN ACCORDANCE WITH THE MANUFACTURED'S INSTALLATION INSTRUCTIONS, LOCAL GAS FITTING REGULATIONS, MUNICIPAL BUILDING CODES, WATER
SUPPLY REGULATIONS, ELECTRICAL WIRING REGULATIONS, AS 5601 / AG 601 - GAS INSTALLATIONS AND ANY OTHER RELEVANT STATUTORY REGULATIONS.
Incorrect installation may cause damage to people, animals and things. The manufacturer will not be
held liable in such events.
2.2 Place of installation
The appliance is intended for outdoor installation only.
The place of installation must in any case be free of dust, inflammable objects or materials and corrosive
gases.
The boiler is supplied ready for wall-hung installation. The rear frame of the appliance has a two slots
for fastening it to the wall, using screws with metal wall plugs. The fastening to the wall must provide
stable and effective support of the appliance.
Upon request a metal wall drilling template is available. This is used exclusively to trace the holes for
fastening the appliance onto the wall, and can be reused for more than one appliance.
2.3 Water connections
The heat capacity of the appliance should be established in advance by calculating of the heating requirements of the building according to the standards in force. For correct operation and long-life of
the boiler, the hydraulic system must be suitably proportioned and always fitted with all the accessories
that guarantee regular operation.
In the case where the central heating outlet and inlet pipes follow paths whereby, at some points, pockets of air may form, air vent valves should be installed at such points.
In addition, a drain device should be installed at the lowest point in the system, to allow complete
emptying.
If the boiler is installed at a lower level than the system, a flow-stop valve should be fitted to prevent
the natural circulation of water in the system.
The thermal head between the outlet manifold and the return inlet of the boiler should not exceed
20°C.
Do not use the water pipes as the earth for electrical appliances.
Before installation, carefully clean all the pipes in the system to remove any residues or impurities that
may affect the correct operation of the appliance.
Make the connections to the corresponding fittings, as shown in fig. 3.

Pressure relief valve
Tempra 30 O incorporates a pressure relief valve discharging at 300 kPa.
The discharge of the pressure relief valve must be con nect ed to a collection container, to avoid
water spill ing onto the ground in the event of over-pres sure in the central heating circuit. The
man u fac tur er of the boiler will not be held liable if this warn ing is not heeded, and the discharge
valve in ter venes and floods the room.
Characteristics of the system water
In the case of water with hardness above 25 French degrees, the water should be suitably treated,
to avoid any deposits in the boiler caused by hard water, or corrosion caused by aggressive water. It
should also be remembered that even minor deposits measuring just a few millimetres thick can cause,
due to their low thermal conductivity, significant overheating of the walls of the boiler, with consequent
serious problems.
The water must always be treated in the case of very large systems (with high water capacity) or systems with the frequent inlet of recovered water. If, in these cases, the system needs to be partially or
completely emptied, it must be refilled with treated water.
Filling the boiler and the system
The boiler is fitted with a ball cock for manually filling the central heating system. The filling pressure,
when the system is cold, must be around 1 bar. If the pressure drops during operation (due to the evaporation of the gas dissolved in the water) to a value lower than the minimum described above, the User
must restore the initial value using the filling cock. For correct boiler operation, the pressure, when hot,
must be around 1,5÷2 bar. Once the operation is completed, always close the filling cock.
2.4 Gas connection
Before making the connections, check that the appliance is configured for operation with the
type of fuel available, and carefully clean all the gas pipes in the system, to remove any residues
that may affect the correct operation of the boiler.
The gas connections must be made at gas inlet (see fig. 3 - key 3), with a rigid metal pipe, or a stainless
steel flexible continuous-wall pipe, fitting a gas cock between the system and the boiler. Before installation, mount the threaded adapter ISO 7-1 contained in boiler package, as shown in fig. 3b. Check that
all the gas connections for tightness.
The capacity of the gas counter must be sufficient for the simultaneous use of all the connected appliances.
The diameter of the gas pipe, which leaves the boiler, does not necessarily determine the choice of the
diameter of the pipe used between the appliance and the gas counter; this must be chosen according
to its length and the pressure drop, according to the standards in force.
Do not use the gas pipes as the earth for electrical appliances.
2.5 Electrical connections
Connection to the mains power supply
The boiler should be connected to a single-phase, 240 Volt-50 Hz electrical line.
The electrical safety of the appliance is ensured only when the appliance is correctly connected
to an effective earth system, as prescribed by the safety standards in force. Have professionally
qualified personnel check the efficiency and the rating of the earth system. The manufacturer
is not liable for any damage caused by the appliance not being correctly earthed. In addition,
make sure that the electrical system is adequately rated for the maximum power absorbed by
the appliance, indicated on the boiler rating plate, and in particular that the cross-section of the
wires is suitable for the power absorbed by the appliance.
The boiler is pre-wired and fitted with a cable for connection to the electrical line. The connections to
the mains supply must be made using a fixed connection, featuring a two-pole switch with a contact
