ECO/COMFORT selection
The unit has a function that ensures a high domestic hot water delivery speed and maximum comfort for the user. When
the device is activated (COMFORT mode), the water contained in the boiler is kept hot, therefore ensuring rapid avail-
ability of hot water on opening the tap, without waiting times.
The device can be deactivated by the user (ECO mode) by pressing the eco/comfort button (detail 7 - fig. 1). To acti-
vate the COMFORT mode, press the eco/comfort button (detail 7 - fig. 1) again.
Outside Temperature Compensation (O.T.C)
When the optional external sensor is installed, the control panel display (detail 5 - fig. 1) shows the actual outside tem-
perature detected by the external sensor. In this mode, the heating system temperature is adjusted according to the
outside weather conditions, to ensure the high comfort and energy saving throughout the year. In particular, as the out-
side temperature increases, the system delivery temperature decreases according to a specific "compensation curve"
(fig. 12).
The maximum system delivery temperature can be set with the heating buttons (details 3 & 4 - fig. 1).
The boiler must be regulated at the time of installation by qualified personnel. Possible adjustments can in any case be
made by the user to improve comfort.
Compensation curve and curve offset (Only required if external sensor is installed)
Press the mode button (detail 10 - fig. 1) once to display the actual compensation curve value (fig. 12) which can be
modified with the DHW buttons (details 1 and 2 - fig. 1).
Adjust the required curve from 1 to 10 according to the characteristic (fig. 14).
By setting the curve to 0, sliding temperature adjustment is disabled.
It is recommended that a start point of 20 to 30°C and a flow temperature of 85°C is suitable for the UK (Curve
9 or 10).
fig. 12 - Compensation curve
Press the heating buttons (details 3 and 4 - fig. 1) to access parallel curve offset (fig. 13), modifiable with the DHW but-
tons (details 1 and 2 - fig. 1).
fig. 13 - Parallel curve offset
Press the mode button (detail 10 - fig. 1) again to exit the parallel curve adjustment mode.
If the room temperature is lower than the required value, it is advisable to set a higher order curve and vice versa. Pro-
ceed by increasing or decreasing in steps of one and check the result in the room (fig. 15).

2.2 Place of installation
The combustion circuit is sealed with respect to the
place of installation and therefore the unit can be in-
stalled in any room. However, the place of installation
must be sufficiently ventilated to prevent the creation
of dangerous conditions in case of even slight gas
leaks. This safety regulation is provided for by EEC Di-
rective no. 90/396 for all gas units, including those with
a sealed chamber.
The unit is suitable for operation in a partially protect-
ed place in conformity with EN 297 pr A6, with mini-
mum temperature -5°C. It is advisable to install the
boiler under the slope of a roof, inside a balcony or in
a sheltered recess.
In any case, the place of installation must be free of
dust, flammable materials or objects or corrosive gas-
es.
The boiler is arranged for wall mounting and comes
standard with a hanging bracket. A paper template for
marking the drilling points on the wall is provided in the
box. The wall fixing must ensure stable and effective
support for the generator.
AIf the unit is enclosed in a cabinet or mounted
alongside, a space must be provided for re-
moving the casing and for normal mainte-
nance operations. The minimum
measurements to be respected are given in
fig. 17.
fig. 17 - Minimum distances around the boiler
AMin. 1 cm
BMin. 15 cm
CMin. 30 cm
DMin. 32 cm (via an openable panel)
2.3 Plumbing connections
Important
The heating capacity of the boiler must be previously established by calculating the building's heat requirement accord-
ing to the current regulations. To ensure proper operation and long boiler life, the plumbing system must be adequately
sized and complete with all the necessary accessories, including a room thermostat, a termostatic radiator valve (TRV),
etc. The system flow and return pipes must have a diameter of at least 22 mm for the first 3 m of length from the unit.
If the system delivery and return pipes follow a path where air pockets could form in certain places, it is advisable to
install vent valves at these points. Also, install type "A" drain cocks at the lowest points in the system to allow complete
emptying.
The temperature drop between the delivery manifold and the return to the boiler should not exceed 20 °C.
A flow rate of at least 6 litres/min through the heat exchanger is required. An automatic bypass installed in the boiler
guarantees maintaining of the required flow rate.
BDo not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the heating system pipes to remove any residuals or impurities that could affect
proper operation of the unit (as required by BS 7593 Building regs Doc L).
Carry out the connections to the unit as indicated in fig. 36.
BThe safety valve discharge must be connected to a 15 mm diameter copper pipe descending from the boiler
to run off system water in case of overpressure in the heating circuit. Otherwise, if the discharge valve cuts in
and floods the room, the boiler manufacturer cannot be held liable. The discharge must be run to the outside
of the building to prevent the risk of damage or injury caused by discharged hot water in case of overpressure
in the system.

cod. 3540S060 - 04/2010 (Rev. 00)
Connections to the boiler are to be made in such a way as to ensure that its internal pipes and fittings are free of stress.
If a non-return valve is installed also on the DHW circuit (if provided for), it is necessary to install a safety valve between
the boiler and circuit (with non-return valve at least 3 metres from the boiler) or an expansion tank for domestic use.
Shutoff valve kit
The shutoff valves supplied (see fig. 18) must be installed between the boiler and heating system to allow the boiler to
be isolated from the system if necessary.
For installation, follow the instructions contained in the kit.

FSystem return cock 3/4” - System filling
Replenishing water
It is necessary to provide for replenishing of the water lost by the sealed system. Refer to standard BS6798 for the
methods of filling and replenishing water in sealed systems. There must not be a direct connection between the central
heating system of the boiler and the water mains. For the use of water coming from the water mains and direct pres-
surisation of the system, refer to the local water management by-laws. This connection, if provided for, must be inter-
rupted after use.
The valve installed in the boiler shell is provided with a filling connector.
Reference is made to the provisions contained in the water management by-laws.
Filling system
The boiler is provided with a special filling system. To
fill the system, remove the plugs “G” and install the re-
movable connection tube “E”. Fill the system by turn-
ing both knobs “L“until the pressure gauge reads a
pressure of 1 ÷ 1.5 bar. Close the knobs “L” and re-
move the connection tube “E”.

Water treatment
If treatment of the water is necessary, Ferroli recommends the exclusive use of specific products such as Fernox or
Sentinel to be applied in compliance with the producer's instructions. For more information, please contact:
AIf the boiler is installed in an existing system, it is necessary to remove any unsuitable additives by thoroughly
cleaning the system. Cleaning of all the systems must be carried out in compliance with the provisions of
Standard B.S. 7593.
AIn areas characterised by the presence of hard water, treatment may be necessary to prevent the formation
of encrustations in the boiler.
AMake sure to use the water treatment product in the correct concentration, in compliance with the producer's
instructions.
2.4 Gas connection
BBefore making the connection, ensure that the unit is arranged for operation with the type of fuel available and
carefully clean all the pipes of the gas system to remove any residues that could affect good functioning of the
boiler.
The gas must be connected to the relative connector (see fig. 36) in conformity with current standards, with rigid metal
pipes or with continuous flexible s/steel wall tubing, placing a gas cock between the system and the boiler. Make sure
that all the gas connections are tight. The capacity of the gas meter must be sufficient for the simultaneous use of all
equipment connected to it. The diameter of the gas pipe leaving the boiler does not determine the diameter of the pipe
between the unit and the meter; it must be chosen according to its length and loss of head, in conformity with current
standards.
BDo not use the gas pipes to earth electrical appliances.
2.5 Electrical connections
The unit must be installed in conformity with current national and local regulations.
Connection to the electrical grid
BThe unit's electrical safety is only guaranteed when correctly connected to an efficient earthing system exe-
cuted according to current safety standards. Have the efficiency and suitability of the earthing system checked
by professionally qualified personnel. The manufacturer is not responsible for any damage caused by failure
to earth the system. Also make sure that the electrical system is adequate for the maximum power absorbed
by the unit, as specified on the boiler dataplate.
The boiler is prewired and provided with a Y-cable and plug for connection to the electricity line. The connections to the
grid must be made with a permanent connection and equipped with a bipolar switch whose contacts have a minimum
opening of at least 3 mm, interposing fuses of max. 3A between the boiler and the line. It is important to respect the
polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) in making connections to the electrical
line. During installation or when changing the power cable, the earth wire must be left 2 cm longer than the others.

Horizontal flue installation
1. Define the position for installing the unit.
2. If using standard flue (041049G0) this must be installed level. For extended horizontal flue lengths over 1m a fall of
3 mm per metre of the flue exhaust should be incorporated back to the boiler.
3. Make a hole of diameter 10 - 20 mm greater than the nominal diameter of the concentric pipe used.
4. If necessary, cut the terminal length to size, ensuring that the external pipe protrudes from the wall by between 10
and 60 mm. Remove the cutting burrs.
5. Connect flue to the boiler, positioning the seals correctly. Seal the flue into the wall with silicone or sand + cement
and cover with wall seals provided.
AFlue seals should be lubricated with a silicone type grease to prevent damage (grease not supplied).

Before proceeding with installation make sure the maximum permissible length has not been exceeded, by means of a
simple calculation:
1. Completely establish the layout of the system of split flues, including accessories and outlet terminals.
2. Consult the table 3 and identify the losses in meq (equivalent metres) of every component, according to the instal-
lation position.
3. Check that the sum total of losses is less than or equal to the maximum permissible length in table 2.

Connection to multiple flues or single flues with natural draught
To connect the EXTREMA boiler to a multiple flue or a single flue with natural draught, the flue or chimney must be
expressly designed by professionally qualified technical personnel in conformity with the current standards and regula-
tions.
In particular, flues and chimneys must:
• Be sized according to the method of calculation given in the standard.
• Be tight with respect to the products of combustion, resistant to the fumes and heat and impermeable to condensate.
• Have a circular or square cross-section (some hydraulically equivalent sections are permissible), with a vertical pro-
gression and with no constrictions.
• Have the ducts conveying the hot fumes at a suitable distance or separately from combustible materials.
• Be connected to just one unit per floor, for not more than 6 units (8 if there is a compensation duct or opening).
• Have no mechanical suction devices in the main ducts.
• Be at low pressure, all along their length, in conditions of stationary operation.
• Have at their base a collection chamber for solid materials or condensate, of at least 0.5 m, equipped with an airtight
metal door.

Condensate drain
If possible, the condensate should be conveyed inside an underground drainage system or pipe. For that purpose, use
a pipe of at least 22 mm diameter and a trap with flexible connection preinstalled in the unit to facilitate connection of
the condensate drain pipe.
The pipe must be in glue-joined plastic and not in copper, since the condensate has a pH of 4 (slightly acid).
If the condensate drain pipe cannot be ended on the inside, it is advisable to run it outside as shown in the following
figure.
The pipe sections going to the outside are exposed to the risk of freezing in particularly extreme weather conditions. To
prevent this from occurring, it is advisable to reduce the length of the condensate drain pipes and run them on the inside,
as much as possible, before going to the outside. It may also be necessary to insulate the condensate pipe or apply a
trace heating device to prevent freezing of the condensate.
The pipes outside the building must be in glue-joined plastic with increased diameter of up to 32 or 40 mm with a max-
imum run of 3m for connection to a condensate collection pit or external drain.
If using a condensate collection pit, it must be as indicated in the figure below, or use a specific system (such as Mc
Alpine SOAK1GR) available from the majority of suppliers of products and accessories for plumbing or heating systems.
