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.
The unit is suitable for indoor installation.
The place of installation must be dry, not exposed to rain, snow or frost, and free of flam-
mable dusts, objects and materials and corrosive gases.
AIf 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
BThe 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.
BBefore installation, carefully wash all the pipes of the system to remove any re-
siduals or impurities that could affect proper operation of the unit.
In case of replacement of generators in existing installations, the system must
be completely emptied and cleaned of any sludge and pollutants. For that pur-
pose only use suitable guaranteed products for heating systems (see next sec-
tion), that do not harm metals, plastics or rubber. The manufacturer declines
any liability for damage caused to the generator by failure to properly
clean the system.
Carry out the relevant connections according to the diagram in fig. 13 and the symbols
on the unit.
fig. 13 - Plumbing connections
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 CaCO3), use suitably treated
water in order to avoid possible scaling in the boiler.
Heating temperature setting
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.
Eco/Comfort selection
On disabling DHW from the Remote Timer Control menu, the
boiler selects the Economy mode. In this condition, the
eco/com-
fort
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 Slid-
ing Temperature adjustment: the boiler card Sliding Temperature
has priority.

Connection to a storage tank for domestic hot water production
The unit's electronic board is arranged for managing an external storage tank for domes-
tic hot water production. Make the plumbing connections according to the diagram of
fig. 14. Make the electrical connections as shown on the wiring diagram in fig. 32. It is
necessary to use the kit code 1KWMA11W. At the next lighting, the boiler's control sys-
tem recognises the presence of the hot water tank probe and is automatically configures
the DHW function, activating the display and relevant controls.

3.4 Gas connection
BBefore making the connection, ensure that the unit is arranged for operation
with the type of fuel available.
The gas must be connected to the relevant connection (see fig. 13) in conformity with the
current standards, using a rigid metal pipe or a continuous surface flexible s/steel tube
and installing a gas cock between the system and boiler. Make sure all the gas connec-
tions are tight.
3.5 Electrical connections
BThe unit must be connected to an efficient earthing system in accordance with
current safety standards. Have the efficiency and suitability of the earthing sys-
tem checked by professionally qualified personnel; the Manufacturer declines
any liability for damage caused by failure to earth the system.
The boiler is prewired and provided with a "Y" type cable (without plug) for con-
nection to the electric line. The connections to the grid must be made with a per-
manent connection and equipped with a bipolar switch whose contacts have a
minimum opening of at least 3 mm, interposing fuses of max. 3A between the
boiler and the line. Make sure to respect the polarities (LINE: brown wire / NEU-
TRAL: blue wire / EARTH: yellow-green wire) in the connections to the electric
line.
BThe unit's power cable must not be replaced by the user. If the cable gets dam-
aged, switch off the unit and have it replaced only by professionally qualified
personnel. In case of replacement, use exclusively “HAR H05 VV-F” 3x0.75
mm2 cable with maximum ext. diameter of 8 mm.
Room thermostat (optional)
BIMPORTANT: 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 de-
vices from their cutoff contacts. Their power supply must be taken with a direct con-
nection 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 51 ***). The layout of the terminals for the various con-
nections is also given in the wiring diagram in fig. 32.

Connection to collective flues
fig. 20 - Examples of connection to flues ( = Air / = Fumes)
Table. 9 - Typology
If the boiler is to be connected BLUEHELIX B 35 to a collective flue or a single flue with
natural draught, the flue or chimney must be expressly designed by professionally qual-
ified technical personnel in conformity with the current regulations and be suitable for
sealed chamber units equipped with fan.
3.7 Condensate drain connection
The boiler has an internal trap for draining condensate. Fit the inspection union Aand
the hose B, pressing it in. Fill the trap with approx. 0.5 l. of water and connect the hose
to the disposal system.
BATTENTION: The unit must never be operated with the trap empty!

4. SERVICE AND MAINTENANCE
4.1 Adjustments
Gas conversion
The unit can operate on Natural Gas or LPG and is factory-set for use with one of these
two gases, as clearly shown on the packing and on the data plate. Whenever a different
gas to that for which the unit is arranged has to be used, a conversion kit will be required,
proceeding as follows:
1. Disconnect the boiler power supply and close the gas cock.
2. Remove the front panel and the panel of the sealed chamber (see fig. 22).
3. Undo the screw and rotate the control panel (see fig. 22).
4. Unscrew the ring Cand Eand remove the gas valve (see fig. 23).
5. Replace nozzle Binserted in the gas pipe with that contained in the conversion kit,
interposing seal D (see fig. 23).
6. Reassemble the valve and check the tightness of the connection.
7. Apply the label, contained in the conversion kit, near the data plate.
8. Refit the front panel.
9. Switch the boiler power on and open the gas cock.
10. Modify the parameter for the type of gas:

TEST mode activation
Press the heating buttons (details 3 and 4 - fig. 1) together for 5 seconds to activate the
TEST mode. The boiler lights at the maximum heating power set as described in the fol-
lowing section.
The heating and DHW symbols (fig. 24) flash on the display; the heating power will ap-
pear alongside.
fig. 24 - TEST mode (heating power = 100%)
Press the heating buttons (details 3 and 4 - fig. 1) to increase or decrease the power
(Min.=0%, Max.=100%).
By pressing the DHW “-” button (detail 1 - fig. 1), boiler output is immediately adjusted
to min. (0%). By pressing the DHW “+” button (detail 2 - fig. 1), boiler output is immedi-
ately adjusted to max. (100%).
If the TEST mode is activated and enough hot water is drawn to activate the DHW mode,
the boiler remains in TEST mode but the 3-way valve goes to DHW.
To deactivate the TEST mode, press the heating buttons (details 3 and 4 - fig. 1) together
for 5 seconds.
The TEST mode is automatically deactivated in any case after 15 minutes or on stopping
of hot water drawing (if enough hot water has been drawn to activate the DHW mode).
Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 4.1). Press the
heating buttons fig. 1 (details 3 and 4 - ) to increase or decrease the power (min. = 00 -
max. = 100). Press the RESET button within 5 seconds and the max. power will remain
that just set. Exit TEST mode (see sec. 4.1).

4.4 Troubleshooting
Diagnostics
In case of operation faults or problems, the display flashes and the fault identification
code appears.
There are faults that cause permanent shutdown (marked with the letter “A”): to restore
operation just press the reset button (detail 6 -fig. 1) for 1 second or RESET on the op-
tional remote timer control if installed; if the boiler fails to start, it is necessary to firstly
eliminate the fault.
Faults marked with the letter “F” cause temporary shutdowns that are automatically reset
as soon as the value returns within the boiler's normal working range.
