f. Using pliers, release spring clip securing condensate
trap body to the heat exchanger bottom drain
connection.
g. First, pull the trap downwards to release from the
heat exchanger. Second, pull the trap end from left
side jacket panel sealing grommet and remove the
trap from boiler.
h. To reinstall the trap, reverse above steps.
i. If the original condensate overow switch is to
be re-used, follow the appropriate switch removal
steps from Condensate Overow Switch Removal
and Replacement procedure above.

overow switch threads and the switch is properly
oriented relative to the trap body - the arrow molded

proper switch operation. See Figure 47 “Condensate
Overow Switch Orientation” for details.
