14 CONDENSATE TRAP
14 .1 Function
The condensate trap "A" in Figure 14.1 and Figure 14.2 allows
the discharge of the condensate via the condensate drain pipe
avoiding in the mean time the escape of combustion products.
Figure 14 .1
If the drain pipe becomes blocked, or condensate cannot drain,
the condensate level in the trap rises until it affects the flame
detection probe, this will cause the boiler lock-out.
14 .2 Check the cleanness of the trap
The condensate drain pipe "A" (Figure 14.2) does not require any
particular maintenance but just check:
1 That no solid deposits have formed, if so remove them.
2 That the condensate drain piping is not clogged.
To clean the inside of the siphon, remove it and turn it upside
down to remove any dirt (see section "14.3 Removal" on page
34).
