CONSTRUCTION
The components of the control box are fixed on a pressed
frame made of thermohardening material, with high
dielectric resistance. The plastic casing protects the device
from possible damages resulting from crashes, incautious
opening, dust and contact with the external environment.
Flexible unipolar conductors of different sizes connect the
components of the control, except for the flame detection
and prepurge control circuit, which is mounted on a printed
circuit.
OVERALL DIMENSIONS
The overall dimensions of the control box are shown in
Fig.2.

cable holders on its sides; also these accessories can be
supplied on request.
