Operating check
Flame monitoring must be checked
for safety as part of initial
commissioning and also after servicing or
if the system has been out of operation for
any significant period of time.
- Start attempt with gas ball valve closed:
the automatic combustion control unit must
switch to gas shortage or malfunction after
the end of the safety period.
Air pressure switch calibration
The air pressure switch is provided for
monitoring the pressure of the
combustion air fan.
Unscrew screws A and B and remove
cover C. After the air and gas setting you
have to calibrate the air switch with the
burner working on the low flame by slowly
turning the relative knob clockwise until the
burner locks out. Read the value and then
decrease it by 15%.
WARNING: the air pressure switch
shall prevent the air pressure to go
below 85% from the adjustment
value in order to prevent the CO in the
fumes to exceed 1% (10000 ppm).
Min gas pressure switch
The gas pressure switch has the function
to check that the gas pressure before the
gas valve does have the minimum
pressure to make the burner running
correctly. Unscrew off and remove cover
M. - Set knob N to a value equal to 60% of
gas nominal feed pressure (i.e. for natural
gas nom. pressure = 20 mbar, set knob to
a value of 12 mbar; for LPG nom. pressure
of G30/G31- 30/37 mbar, set knob to a
value of 18 mbar). Screw up cover M.
