ATLAS D 34 CONDENS K130 UNIT
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).
fig. 15 - Low system pressure fault
Filling cock kit
The boiler is provided with a kit comprising a filling cock.
The 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.

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

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 the safety check valve (supplied with the boiler) on
B
the cold water inlet.
High efficiency hot water tank circulating pump
For proper operation of the boiler ATLAS D 34 CONDENS K130 UNIT, the speed selec-
tor (see fig. 17) must be set to position III.
High efficiency heating circulating pump
The factory setting is suitable for all installations; however a different operation strategy
can be set, depending on the characteristics of the system.

Proportional head

- Proportional Head Dp-v setting (fig. 18)
The circulating pump head will be automatically reduced with the decrease in flow rate
required by the system. This setting is optimum for systems with radiators (2 pipes or sin-
gle pipe) and/or thermostatic valves.
The strong points are the reduction in power consumption with the decrease in system
demand and reduction of noise in radiators and/or thermostatic valves. The operating
range is from min. (1) to max. (7).
- Setting Fixed speed (fig. 19)
The circulating pump does not modulate its power. The operating principle is that of con-
ventional 3-speed circulating pumps (with a reduction in power consumption compared
to them). The operating range goes from speed 1 (I) to speed 3 (III).
Water system characteristics
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.
If water softeners are installed at the boiler cold water in-
B
let, make sure not to reduce the water hardness too
much, as this could cause early deterioration of the mag-
nesium anode in the hot water tank.
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.
