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 B 32 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 approx. 0.5 l. of water and connect the hose
to the disposal system.

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 (see fig. 24).
3.
Undo the screw and rotate the control panel (see fig. 21).
4.
Unscrew ring C and remove gas pipe A from the gas valve (see fig. 22).
5.
Replace nozzle B inserted in the gas pipe with that contained in the conversion kit,
interposing seal D (see fig. 22).
6.
Refit gas pipe A 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:
