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. Also, the control pan-
el display (detail 5 - fig. 1) shows the actual room temperature detected by the
Remote Timer Control.
Table. 1
Heating temperature setting Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.
DHW temperature adjustment Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.
Summer/Winter Switchover Summer mode has priority over a possible Remote Timer Control heating
demand.
On disabling DHW from the Remote Timer Control menu, the boiler selects the
Economy mode. In this condition, the button 7 - fig. 1 on the boiler panel is dis-
abled.
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 button 7 - fig. 1 on the boiler panel.
Sliding Temperature Both the Remote Timer Control and the boiler card manage Sliding Temperature
adjustment: of the two, the Sliding Temperature of the boiler card has priority.
System water pressure adjustment
The filling pressure with system cold, read on the display, must be approx. 1.0 bar. If the
system pressure falls to values below minimum, the boiler card will activate fault F37
(fig. 15).

Optional filling cock and vessel kit
An optional kit comprising a DHW expansion vessel and a filling cock is available on re-
quest.
The filling cock must be installed respecting the direction of the arrow.
When installed, operate the filling cock (detail 1 - fig. 16) to bring the system pressure to
a value above 1.0 bar.

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

The boiler unit must be installed in a specific room with ventilation openings to the out-
side as prescribed by current regulations. If there are several burners or suction units
that can work together in the same room, the ventilation openings must be sized for si-
multaneous operation of all the units. The place of installation must be free of flammable
materials or objects, corrosive gases, powders or volatile substances that, conveyed by
the burner fan, can obstruct the internal lines of the burner or the combustion head. The
room must be dry and not exposed to rain, snow or frost.
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

The heating capacity of the unit must be previously established by calculating the build-
ing's heat requirement according to the current regulations. The system must be provid-
ed with all the components for correct and regular operation. It is advisable to install
shutoff valves between the boiler and heating system allowing the boiler to be isolated
from the system if necessary.
The safety valve outlet must be connected to a funnel or
B
collection pipe to prevent 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
manufacturer cannot be held liable.
Do not use the water system pipes to earth electrical ap-
pliances.
Before installation, flush all the pipes of the system thoroughly to remove any residuals
or impurities that could affect proper operation of the unit.
Carry out the relevant connections according to the diagram in cap. 5 and the symbols
given on the unit.
Install on the cold water inlet the safety check valve "A"
B
(see fig. 17) supplied with the boiler. Respect the direction
of the arrow on the valve.
Install on the system delivery the non-return valve "A"
B
(see fig. 18) supplied with the boiler, interposing the gas-
ket "B". Respect the direction of the arrow on the valve.
