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

ture adjustment: of the two, the Sliding Temperature of the boiler card has prior-
ity.
Water system 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).

ATLAS D ECO COND UNIT
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.
7 6 5
4
B
The safety valve outlet must be connected to a funnel or collection pipe to pre-
3
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-
2
facturer cannot be held liable.
1
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
Circulating pump adjustment with boiler connected to an external hot water stor-
age tank
For proper operation of the boiler ATLAS D ECO COND UNIT with it connected to an external
hot water storage tank, the speed selector (see fig. 16) must be set to position III.
Circulating pump adjustment without a connection to an external hot water storage tank
The factory setting is suitable for all installations; however a different operation strategy
can be set, depending on the characteristics of the system.
