If after four ignition attempts (about four min-
utes) the boiler does not function and a code
that precedes the letter E and the writing RE-
SET appear on the LCD display, it indicates
that the safety lock-out has stopped the boiler.
The display background flashes (Fig. 7.13).

Press the reset key on the boiler control panel
15 (Fig. 7.11) to reset its functioning.
For the first lighting up and following mainte-
nance procedures for the gas supply, it may
be necessary to repeat the resetting operation
several times so as to remove the air present
in the pipework.
After five consecutive resetting attempts the
reset button is inhibited. To restore its func-
tion it is necessary to switch the boiler off and
on from the electrical mains, using the fused
spur isolation switch fitted adjacent to the ap-
pliance.
