ATLAS ECO 30 SI UNIT
Adjustments from Remote Timer Control
If the boiler is connected to the Remote Timer Control (optional), the previously
A
described adjustments are managed as described in table 1.
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 possible Remote Timer Control heating
demand.
On disabling DHW from the Remote Timer Control menu, the boiler selects
Economy mode. In this condition, the eco/comfort function from the control
panel is disabled.
Eco/Comfort selection
By enabling DHW from the Remote Timer Control menu, the boiler selects
Comfort mode. In this condition, the eco/comfort function can be selected from
the boiler control panel.
Sliding Temperature Both the Remote Timer Control and the boiler card manage Sliding Tempera-
ture adjustment: Sliding Temperature overrides the boiler card.
System water pressure adjustment
The filling pressure read on the boiler water gauge with the system cold must be approx.
1.0 bar.
Operating the filling cock, bring the system pressure to a value above 1.0 bar.
Always close the filling cock at the end of the operation.

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.
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.
Do not use the water system pipes to earth electrical appliances.
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.
High efficiency circulating pump
For proper operation of the boiler ATLAS ECO 30 SI UNIT, the speed selector (see
fig. 16) must be set to position III.

Characteristics of the water system
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO3), use suitably treated
water in order to avoid possible scaling in the boiler. Treatment must not reduce the hard-
ness to values below 15°F (Decree 236/88 for uses of water intended for human con-
sumption). Treatment of the water used is indispensable in case of very large systems
or with frequent introduction of replenishing water in the system.
Antifreeze system, antifreeze fluids, additives and inhibitors
The boiler is equipped with an antifreeze system that turns on the boiler in heating mode
when the system delivery water temperature falls under 6°C. The device will not come
on if the electricity and/or gas supply to the unit are cut off. If it becomes necessary, it is
permissible to use antifreeze fluid, additives and inhibitors only if the manufacturer of
these fluids or additives guarantees they are suitable for this use and cause no damage
to the heat exchanger or other components and/or materials of the boiler unit and sys-
tem. It is prohibited to use generic antifreeze fluid, additives or inhibitors that are not ex-
pressly suited for use in heating systems and compatible with the materials of the boiler
unit and system.

3.4 Burner connection

The burner is equipped with flexible pipes and a filter for connection to the oil feed line.
Run the flexible pipes out of the back and install the filter as indicated in fig. 17.
fig. 17 - Fuel filter installation
The oil feed circuit must be made according to one of the following diagrams, without ex-
ceeding the pipe lengths (LMAX) given in the table.
