Various types of control boxes are fitted to the NOL
18-100 High/Low series of burners. This manual
covers the standard models from Satronic and
Landis & Staefa.
The units are designed to provide control and
supervision for atomising oil burners of medium
to large capacity. They are suitable for use on multi-
stage and modulating burners.
For safety reasons, at least one controlled
shutdown must be provided within each 24-hour
period of continuous operation.
