AIR PRESSURE SWITCH
The air pressure switch stops the equipment operation if air pressure
is not at the expected value.
The pressure switch must therefore be adjusted so that it is triggered
to close the NO (normally open) contact when the air pressure in the
burner reaches the set value.
If the air pressure switch does not detect a pressure greater than that
calibrated, the equipment runs through its cycle but does not switch on
the ignition transformer and does not open the gas valves and so the
burner “locks-out”.
To ensure the air pressure switch correct operation, with burner at
the minimum output, increase the adjustment value until reaching the
triggering value which must be followed by the immediate burner lock-
out.
To unblock the burner, press the special pushbutton and return the
pressure switch regulator to a sufficient value in order to measure the
air pressure existing during the pre-ventilation phase.
Adjust the setting of the pressure switch to a level slightly below the
actual air pressure detected in first stage operation. Release the burner
and check that it starts up correctly.
