BLUEHELIX TECH S 45H
Proceed in reverse order to refit the front panel. Make sure it is correctly hooked to the
upper fastenings and is correctly positioned at the sides. When tightened, the head of
screw "A" must not be below the lower fold (see fig. 25).

Periodical check
To ensure proper operation of the unit over time, have qualified personnel carry out a
yearly inspection, providing for the following checks:
• The control and safety devices (gas valve, flow meter, thermostats, etc.) must func-
tion correctly
• The fume exhaust circuit must be perfectly efficient
• The sealed chamber must be tight
• The air-fume end piece and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits For possible cleaning
do not use chemical products or wire brushes
• The electrode must be properly positioned and free of scale
• The gas and water systems must be tight.
• The water pressure in the cold water system must be about 1 bar; otherwise, bring
it to that value
• The circulating pump must not be blocked.
• The expansion tank must be filled.
• The gas flow and pressure must correspond to that given in the respective tables
• The condensate evacuation system must be efficient with no leakage or obstruc-
tions
• The trap must be full of water.
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.

Cure
Check the regular gas flow to the
boiler and that the air has been
eliminated from the pipes
Check the wiring of the electrode and
that it is correctly positioned and free
of any deposits
Check the gas valve and replace it if
necessary
Check the gas supply pressure
Check the trap and clean it if
necessary
Check the ionisation electrode wiring
Check the card
Check the correct positioning and
operation of the heating sensor
Check the circulating pump
