BLUEHELIX PRO C
Antifreeze system, antifreeze fluids, additives and inhibitors
When necessary, antifreeze fluids, additives and inhibitors can be used only if the man-
ufacturer of such fluids or additives guarantees that they are suitable and do not cause
damage to the exchanger or other components and/or materials of the boiler and system.
Do not use generic antifreeze fluids, additives or inhibitors that are not specific for use in
heating systems and compatible with the materials of the boiler and system.
Water system characteristics
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO
water in order to avoid possible scaling in the boiler.
Antifreeze kit for outdoor installation (optional)
In case of installation outdoors in a partially protected place for temperatures lower than
-5°C and down to -15°C, the boiler must be equipped with the antifreeze kit to protect the
tap water circuit and air trap. The kit comprises a thermostat, electric heaters and a heat-
er for the air trap. Connect the kit to the electronic card and install the thermostat and
heaters on the tap water pipes as directed in the instructions attached to the kit.

3.4 Gas connection

B
Before making the connection, ensure that the unit is arranged for oper-
ation with the type of fuel available.
The gas must be connected to the corresponding union (see fig. 14) in
conformity with current regulations, with a rigid metal pipe or with a con-
tinuous flexible s/steel tube, installing a gas cock between the system
and boiler. Make sure that all the gas connections are tight. Otherwise
there may be a risk of fire, explosion or suffocation.

3.5 Electrical connections

IMPORTANT
B
BEFORE CARRYING OUT ANY OPERATION THAT REQUIRES REMOVING
THE CASING, DISCONNECT THE BOILER FROM THE ELECTRIC MAINS
WITH THE MAIN SWITCH.
NEVER TOUCH THE ELECTRICAL COMPONENTS OR CONTACTS WITH
THE MAIN SWITCH TURNED ON! DANGER OF ELECTRIC SHOCK WITH
RISK OF INJURY OR DEATH!
B
The unit must be connected to an efficient grounding system in accordance with
applicable safety regulations. Have the efficiency and suitability of the ground-
ing system checked by professionally qualified personnel; the Manufacturer de-
clines any liability for damage caused by failure to earth the system.
The boiler is prewired and provided with a three-pole cable, without a plug, for
connection to the electric line. The connections to the grid must be made with
a permanent connection and equipped with a bipolar switch whose contacts
have a minimum opening of at least 3 mm, interposing fuses of max. 3A be-
tween the boiler and the line. Make sure to respect the polarities (LINE: brown
wire / NEUTRAL: blue wire / GROUND: yellow-green wire) in the connections
to the electric line.
B
The unit's supply cable MUST NOT BE REPLACED BY THE USER. If the ca-
ble gets damaged, turn the unit off and have the cable replaced only by
professionally qualified personnel. In case of replacement, only use cable
"HAR H05 VV-F" 3x0.75 mm2 with max. external diameter of 8 mm.
Room thermostat (optional)
B
IMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTAGE-FREE
CONTACTS. CONNECTING 230V TO THE ROOM THERMOSTAT TERMI-
NALS WILL PERMANENTLY DAMAGE THE PCB.
When connecting a time control or timer, do not take the power supply for such
devices from their cutoff contacts. Their power supply must be taken with a direct
connection from the mains or with batteries, depending on the type of device.
Accessing the electrical terminal block
The electrical terminal block (fig. 15) can be accessed after removing the front panel (***
'Opening the front panel' on page 44 ***) . The arrangement of the terminals for the var-
ious connections is also given in the wiring diagram in fig. 31.

Important
The unit is "type C" with sealed chamber and forced draught; the air inlet and fume outlet
must be connected to one of the following extraction/suction systems. Before installation,
check and carefully observe the above prescriptions. Also, comply with the provisions
concerning the positioning of wall and/or roof terminals and the minimum distances from
windows, walls, vents, etc.

For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to the figure on the cover. Any horizontal sections of the fume
exhaust must be kept sloping slightly towards the boiler, to prevent possible condensate
from flowing back towards the outside and causing dripping.

THE BOILER MUST BE INSTALLED IN PLACES THAT MEET THE FUNDA-
MENTAL REQUIREMENTS FOR VENTILATION. OTHERWISE THERE IS A
DANGER OF SUFFOCATION OR INTOXICATION.
READ THE INSTALLATION AND MAINTENANCE INSTRUCTIONS BE-
FORE INSTALLING THE UNIT.
