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 availability 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 activate 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 temperature 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 outside 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).

2.2 Place of installation
The combustion circuit is sealed with respect to the
place of installation and therefore the unit can be installed 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 Directive no. 90/396 for all gas units, including those with
a sealed chamber.
The unit is suitable for operation in a partially protected place in conformity with EN 297 pr A6, with minimum 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 gases.
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.

2.3 Plumbing connections
Important
The heating capacity of the boiler must be previously established by calculating the building's heat requirement according 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.
Do not use the water system pipes to earth electrical appliances.
B
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.
The safety valve discharge must be connected to a 15 mm diameter copper pipe descending from the boiler
B
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.

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 regulations.
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 progression 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.
2.7 Condensate drain connection
Installation
The boiler has an internal condensate drain trap.
For installation, remove the protection bracket A which will not be used.
Fit the inspection union B and the flexible tube C, pressing it in for approx. 3 cm.
Fill the trap with approx. 0.5 l. of water D and connect the flexible tube to the drainage system or a condensate collection
pit E.

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 maximum 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.

Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault, the display will flash together
with the fault symbol (detail 22 - fig. 1) indicating the fault code (detail 21 - fig. 1).
Certain faults cause permanent boiler shutdowns (marked with the letter “A”): to restore operation, press the RESET
button (detail 8 - fig. 1) for 1 second or RESET on the optional remote timer control if installed; if the boiler fails to start,
it is necessary to firstly eliminate the fault.
other faults (indicated with the letter “F”) cause temporary shutdowns that are automatically reset as soon as the value
returns within the boiler's normal working range.
