Cleaning th siphon
Remove the siphon as described below:
 Switch off the electrical supply by turning the system’s main switch to “Off.
 Disconnect the degassing pipe (see figure below)
 Disconnect the condensate drain pipe coming from the exchanger (see
figure below).
 Remove the clip securing the siphon to its manifold (see figure below).
 Remove the siphon from its seat.
 Wash the siphon by circulating water from the connection with the
hose nozzle. IN NO CASE USE METAL OR POINTED TOOLS TO
REMOVE DEPOSITS OR RESIDUES INSIDE AS THEY COULD
DAMAGE ITS COMPONENTS.
b
Do not remove the safety shutter and its sealing gasket as their
presence is intended to prevent the escape of burnt gases into the
environment in the event of no condensation.
 Oncetheoperationshavebeencompleted,reassemblethecomponents
byoperatinginthereverseordertowhatisdescribed,checkingthecorrect
positioningandintegrityofthesealingOR,andreplaceitifnecessary.
