5.5 FLUE EXHAUST PORTS (SUCTION TYPE MODEL)
On the boiler top there is installewd an outlet socket (60/100) for connection with suction type exhaust pipes .
Two pressure ports allow measuring quality of combustion during the COMBUSTION ANLYSIS mode as well
as 2 pressure taps are provided for pressure switch tests.
5.6. AIR PRESSURE SWITCH (SUCTION CAP TYPE DESIGN)
The boiler is fitted with an air pressure switch to check the vacuum state in suction caps and the extractor
for regular functioning.

25kW: Off =
50Pa/0,50 mbar
On =
60Pa/0,60 mbar


30kW: Off =
74Pa/0,74 mbar
On =
89Pa/0,89 mbar
The pressure tap (-) of the pressure switch is jointed to the pressure tap in the extractor.
The pressure tap (+) is measured directly in the casing of the air pressure switch.
A measurement of Dp is taken during every sequence of ignition. If the read value is correct, the burner can
ignite a flame.
In thepresence of any trouble, faults of 2 types are likely to be found:
6 07 : pressure switch contact closed while extractor is not powered yet.
6 P1 : pressure switch contact remains open while extractor is being energized.
For preventing condensation risks from occuring in the pressure switch tube, a regenerator for
condensate is fitted in the tube.
