If the room temperature is lower than the required value, it is advisable to set a higher
order curve and vice versa. Proceed by increasing or decreasing in steps of one and
check the result in the room.

Adjustments from Remote Timer Control
If the Remote Timer Control (optional) is connected to the boiler, the above ad-
A
justments are managed according to that given in table 1.
Table. 1
Adjustment can be made from the Remote Timer Control menu and the boiler
Heating temperature setting
control panel.
Adjustment can be made from the Remote Timer Control menu and the boiler

demand.
On disabling DHW from the Remote Timer Control menu, the boiler selects
the Economy mode. In this condition, the eco/comfort button (detail 7 - fig. 1)
on the boiler panel is disabled.
Eco/Comfort selection
On enabling DHW from the Remote Timer Control menu, the boiler selects the
Comfort mode. In this condition it is possible select one of the two modes with
the eco/comfort button (detail 7 - fig. 1) on the boiler panel.
Both the Remote Timer Control and the boiler card manage Sliding Tempera-
Sliding Temperature
ture adjustment: the boiler card Sliding Temperature has priority.
System water pressure adjustment
The filling pressure read on the boiler water gauge with the system cold must be approx
1.0 bar. If the system pressure falls to values below minimum, the boiler stops and fault
F37 is displayed. Operate the filling cock (detail 1 - fig. 12) and bring it to the initial value.
Always turn it off it afterwards.
Once the system pressure is restored, the boiler will activate the 300-second air venting
cycle indicated on the display by FH.

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
B
The combustion circuit is sealed with respect to the place of installation,
therefore the unit can be installed in any room. The place of installation
must be adequately ventilated to avoid the creation of dangerous condi-
tions in case of any gas leaks. This safety standard is required by the EEC
Directive no. 2009/142 for all gas units, including those with sealed cham-
ber.
The unit is suitable for indoor installation.
The place of installation must be dry, not exposed to rain, snow or frost, and free of flam-
mable dusts, objects and materials and corrosive gases.
If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
A
vided for removing the casing and for normal maintenance operations.
3.3 Plumbing connections
Important
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.
B
Before installation, carefully clean all the system pipes to remove any residuals
or impurities that could affect proper operation of the unit.
In case of replacement of generators in existing installations, the system must
be completely emptied and cleaned of any sludge and pollutants. For that pur-
pose only use suitable guaranteed products for heating systems (see following
section), that do not harm metals, plastics or rubber. The manufacturer de-
clines any liability for damage caused to the generator by failure to prop-
erly clean the system.
Carry out the relevant connections according to the diagram in fig. 13 and the symbols
on the unit.

Antifreeze system, antifreeze fluids, additives and inhibitors
When necessary, antifreeze fluids, additives and inhibitors can be used only if the man-
ufacturer of such fluids or additives guarantees that they are suitable and do not cause
damage to the exchanger or other components and/or materials of the boiler and system.
Do not use generic antifreeze fluids, additives or inhibitors that are not specific for use in
heating systems and compatible with the materials of the boiler and system.
Water system characteristics
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO
