Condensate trap

21.1

Function

The condensate trap A in Fig. 21.1 and Fig. 21.2 allows
the discharge of the condensate via the condensate
drain pipe avoiding in the mean time the escape of
combustion products.
A plastic ball closes the trap outlet in case that the trap
is empty.

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 till it reaches a screw that is in con-
tact with the flame detection circuit thus causing the
boiler lock ---out.
