COLLECTION SIPHON
Before starting the boiler you have to fill the
condensate collection siphon in order to avoid fuel
reflux through the siphon.
Fill the condensate collection siphon as follows
(see fig. 5):
› Unscrew the “T” cap from the siphon, fill three
quarters of the the siphon with water and screw
the “T” cap back in;
› Connect the dedicated flexible condensate
draining tube “P” (UNI EN 677) to a waste
disposal system. The condensate can be drained
directly in the sewerage system by inserting an
easily serviceable siphon.
