Ignition; Fault Code - Joannes EPOCA 24-29 NS User Manual

IGNITION

Open the gas tap, press the ON button. The burner will ignite automatically (the heating and hot water
functions are set by the manufacturers).
Should the unit fail to ignite there will be another three ignition attempts after which there will be a shutdown
(the display will flash 2 - 02). Press RESET: if the unit still fails to ignite contact the technical assistance service.

FAULT CODE

The boiler control box is equipped with a microprocessor that memorises and signals any faults or shutdowns.
The fault type is indicated by a flashing code.
The meaning of each code is given in the table below:
