Condensate trap

21.1

Function

The condensate trap A in Fig. 89 and Fig. 91 allows the
discharge of the condensate via the condensate drain
pipe avoiding in the mean time the escape of combus-
tion products.
A plastic ball closes the trap outlet in case that the trap
is empty.

The condensate trap is provided with two electrodes.
The electrode B is connected to the ground circuit; the
electrode C is connected to the flame detecting elec-
trode (Fig. 90).

If the drain pipe is plugged or in any case in which the
condensate isn't correctly evacuated, the condensate
level in the trap rises putting in contact the electrodes
thus causing the boiler lock ---out.
