14 Condensate trap
14.1 Function
The condensate trap
A
in Fig. 14.1 and Fig. 14.3 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 becomes blocked, or condensate can-
not drain, the condensate level it the trap rises until it re-
aches the screw attached to the flame detection elec-
trode, this will cause the boiler lock---out.
