Reset push button
In order to restart the boiler
when the lockout symbol is
displayed, it will be necessary to
push this button.
Chimney sweeper button
This push button, depressed for
3 seconds, activates the
chimney sweeper function: the
boiler will be forced to operate at
the maximum (or minimum)
capacity, in order to allow the
gas valve adjustment and the
smoke analysis.
When this function is activated,
by pushing this button once, the
boiler will operate at maximum
capacity. The radiator symbol will
be blinking, while the flame
symbol will be permanently
lighted.
By pushing again the button
(when the boiler is set to the
maximum capacity), the boiler will
operate at minimum capacity. The
radiator and the flame symbols,
both, will be blinking.
In order to clear this function
switch OFF and ON the boiler; if
not, the boiler will revert to nor-
mal operation after 15 minutes.
