CoNDENSATE TRAP
21 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.

If the drain pipe becomes blocked, or condensate cannot drain,
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.

Unscrew the plug on the bottom of the trap and remove dirt even-
tually deposit.

ty supply before removing any covering or compo-
