It is strongly recommended a periodic check
of the pump pressure operation (annually or
better every six months, if the burner opera-
tion is continuous).
If the value is lower than 1 bar, compared to
that one of the initial setting, please check
the cleaning of the pump and line filters.
In case the pressure setting was not restora-
ble, please replace the pump, in order to
guarantee that the pump pressure during the
pre-purge time is at least 3.7 bar.
