The pneumatic ratio control sys-
tem controls the gas pressure on
the burner proportionally to the air
pressure and thus maintains a con-
stant air/gas ratio. At the same time,
it acts as a low air pressure protec-
tion device.
The ignition and monitoring of the
individual burners is ensured by
burner control unit BCU 460 with
power module LM..F3.
The centrally checked safety func-
tions such as pre-purge, tightness
test, flow detector and pressure
switch check (gas , gas
