Cause
Remedy
¡
The union nut on the combustion tube is
not tightened correctly (after catalyst re-
placement).
¡
The carrier gas supply to the furnace
head or lock is not connected properly
(after catalyst replacement).
¡

tube are defective (heavily deformed) or
not attached (after catalyst replace-
ment).
¡
The FAST connector on the TIC conden-
sate container is leaky.
¡
The connections on the water trap sys-
tems are loose (after water trap replace-
ment or halogen trap maintenance).
¡
Check the screw connections for com-
pleteness and deformations. Tighten as
necessary.

Check the flow with an external mass
flow sensor if possible to confirm the er-
ror.
¡
Inform the service.
