CoNDENSATE TRAP
21.1 function
The condensate trap A in Figure 21.1 and Figure 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.

the condensate level it the trap rises until it reaches the screw at-
tached to the flame detection electrode, this will cause the boiler
lock out.

tually deposit.
