Service And Maintenance; Condensate Drain Connection - Ferroli BLUEHELIX 25 K 50 Instrucciones De Uso, Instalación Y Mantenimiento

Before 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 the table 6 and identify the losses in m
ponent, 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.

Type Description
C2X Intake and exhaust in common flue (intake and exhaust in same flue)
C4X Intake and exhaust in common and separate flues , but undergoing similar wind conditions
C8X Exhaust in single or common flue and wall intake
B3X Intake from installation room by means of concentric duct (that encloses the exhaust) and exhaust in
common flue with natural draught
IMPORTANT - THE ROOM MUST BE PROVIDED WITH APPROPRIATE VENTILATION
If the boiler is to be connected BLUEHELIX 25 K 50 to a collective flue or a single flue
with natural draught, the flue or chimney must be expressly designed by professionally
qualified 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 A and
the hose B, pressing it in. Fill the trap with about 0.5 L of water and connect the hose to
the disposal system.

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 39 ***).
2. Undo the screw and rotate the control panel (see fig. 21).
3. Unscrew ring C and remove gas pipe A from the gas cock (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. Reassemble 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 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 content in the fumes, with the boiler operating at max. and min. output, corre-
2
sponds to that given in the technical data table for the corresponding type of gas.
