EURO-OIL SERIES
TYPE G22 series 09
AUTOMATIC OIL BURNER CONTROL
APPLICATION
SYSTEMS This range of electronic oil burner controls has been
specifically designed for oil burners for non permanent
operation.
The automatic burner controls of this series are suitable for:
− monobloc oil burners
− warm air generators
− steam boilers
− power washers
− kilns
Due to the technical and structural characteristics and to the
variety of models they can be used for the automation of
cookers and oil burner operated appliances for domestic and
industrial applications.
FEATURES
The G22 series 09 oil burner controls, simple wiring and
installation. The main features of this series are following:
− for non permanent operation;
− for one-stage oil burners (single flame);
− prearranged for appliances with pre-heater (see
“CONNECTION DIAGRAMS”);
− maximum heat input according to the European standard
EN 267:1999-09:
- ≤ 30 kg/h (max. ignition safety time 10 seconds)
- > 30 ≤ 100 kg/h (max. ignition safety time 5 seconds)
the pre-purge time has to be set in compliance with
nominal fuel throughput of the burner;
− in accordance with the European standard DIN EN
230:1991-05 concerning monobloc oil burners, safety
control and regulation devices. The DIN registration
number relevant to this series of devices is the following:
5F165/04
− in compliance with the standard DIN 4794 part 2, edition
December 1980 regarding warm air generators WLE
(only version with TV = 20s and TS = 5s);
− operation with flame detector type FC7/FC8;
− two independent safety contacts for oil valve(s) control;
− electrical service life at max load >250.000 operations;
− simple wiring and installation.

Times
- Pre-purge time (TV) 1,5/10/20/30/40 s
- Ignition safety time (TS) 5/10 s
- Dropout time on running flame failure: < 1s
The times given on the burner control label correspond to the
values guaranteed. The actual values slightly differ from the
values given, as prepurge time can be longer and safety time
shorter than their nominal values.
