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
A
If the Remote Timer Control (optional) is connected to the boiler, the above ad-
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 read by the
Remote Timer Control.
Table. 1
Heating temperature adjustment 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 Remote Timer Control heating demand.
Eco/Comfort selection 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.
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.
Sliding Temperature Both the Remote Timer Control and the boiler card manage Sliding Tem-
perature adjustment: of the two, the boiler card Sliding Temperature has
priority.
System water pressure adjustment
The filling pressure with system cold, read on the boiler water gauge, must be approx.
1.0 bar. If the system pressure falls to values below minimum, the boiler card will activate
fault F37 (fig. 15).
fig. 15 - Low system pressure fault - Filling cock
Operate the filling cock (detail 1 - fig. 15) and bring the system pressure to a value above
1.0 bar.
At the bottom of the boiler there is a pressure gauge (detail 2 - fig. 15) to show the pres-
sure even when there is no power supply.
A
Once the system pressure is restored, the boiler will activate the 120-second
air venting cycle indicated on the display by FH.
At the end of the operation always close the filling cock (detail 1 - fig. 15)

3. BOILER 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 STANDARDS AND LOCAL REGULATIONS AND THE RULES OF PROPER
WORKMANSHIP

3.2 Place of installation

The combustion circuit is sealed with respect to the place of installation, therefore the
unit can be installed in any room. However, the place of installation must be sufficiently
ventilated to prevent the creation of any dangerous conditions in case of even small gas
leaks. This safety precaution is required by EEC Directive no. 90/396 for all gas units,
including those with a so-called sealed chamber.
Therefore the place of installation must be free of dust, flammable materials or objects
or corrosive gases. The room must be dry and not subject to freezing.
The boiler is arranged for wall mounting and comes standard with a hooking bracket. The
wall fixing must ensure stable and effective support for the generator.
A
If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
vided for removing the casing and for normal maintenance operations

3.3 Plumbing connections

Important
5
The heating capacity of the unit must be previously established by calculating the build-
4
ing's heat requirement according to the current regulations. The system must be provid-
3
ed with all the components for correct and regular operation. It is advisable to install on-
2
off valves between the boiler and heating system allowing the boiler to be isolated from
1 the system if necessary.
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-
-20 facturer cannot be held liable.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the pipes of the system to remove any residuals or
impurities that could affect proper operation of the unit.
B
Also, a filter must be installed on the system return piping to prevent impurities
or sludge from the system clogging and damaging the heat generators.
The filter must be installed when replacing generators in existing systems. The
manufacturer declines any liability for damage caused to the generator by fail-
ure to install or inadequate installation of this filter.
Carry out the relevant connections according to the cover diagram and the symbols giv-
en on the unit.
