1. Partially undo the screws A (see fig. 24).
2. Pull the panel B outwards and release it from the upper fastenings.

Before carrying out any operation inside the boiler, disconnect the power and close the gas cock upstream

fig. 24 - Front panel opening

On this unit, the casing also acts as a sealed chamber. After any operation involving opening the boiler, carefully check the correct refitting of the front panel and its seal.

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 function 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 obstructions
  • 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 optional 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.
