EN
For the connection of separate ducts, fit the unit with the following starting accessory:
fig. 18 - Starting accessory for separate ducts
Before proceeding with installation make sure the maximum permissible length has not
been exceeded, by means of a simple calculation:
1. Completely establish the layout of the system of split flues, including accessories
and outlet terminals.
2. Consult table 6 and identify the losses in m
eq
(equivalent metres) of every compo-
nent, according to the installation position.
3. Check that the sum total of losses is less than or equal to the maximum permissible
length in table 5.

fig. 19 - Examples of connection to flues ( = Air / = Fumes)
Table. 7 - Typology
If the boiler is to be connected BLUEHELIX TECH S 45H to a collective flue or a single
flue with natural draught, the flue or chimney must be expressly designed by profession-
ally qualified technical personnel in conformity with the current regulations and be suita-
ble 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 A and
the hose B, pressing it in. Fill the air-trap with approximately 0.5 l. of water and connect
the hose to the disposal system
B
ATTENTION: 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. Remove the front panel (see *** 'Opening the front panel' on page 38 ***).
2. Undo the screw and rotate the control panel (see fig. 21).
3. Unscrew ring C and remove gas pipe A from the gas valve (see fig. 22).
4. Replace nozzle B inserted in the gas pipe with that contained in the conversion kit,
interposing seal D (see fig. 22).
5. Refit gas pipe A and check the tightness of the connection.
6. Apply the label, contained in the conversion kit, near the data plate.
7. Refit the front panel.
8. Modify the parameter for the type of gas:
• put the boiler in standby mode
• press the DHW buttons (details 1 and 2 - fig. 1) for 10 seconds: the display
shows “b01” flashing.
• press the DHW buttons (details 1 or 2 - fig. 1) to set parameter 00 (for operation
with natural gas) or 01 (for operation with LPG).
• press the heating + button (detail 4 - fig. 1) until “b04” flashes on the display.
• press the DHW buttons (details 1 or 2 - fig. 1) to set parameter 200 (for opera-
tion with natural gas) or 190 (for operation with LPG).
• press the heating + button (detail 4 - fig. 1) until “b05” flashes on the display
• press the DHW buttons (details 1 or 2 - fig. 1) to set parameter 200 (for opera-
tion with natural gas) or 190 (for operation with LPG).
• press the DHW buttons (details 1 and 2 - fig. 1) for 10 seconds.
• the boiler will return to standby mode
9. Using a combustion analyser connected to the boiler fume outlet, check that the
CO
2
content in the fumes, with the boiler operating at max. and min. output, matches
that given in the technical data table for the corresponding type of gas.
