2.7 Condensate drain connection
IMPORTANT
The boiler has an internal trap for draining condensate. Install the hose “B” by pressing it into
place. Before commissioning, fill the trap with approx. 0.5 L of water and connect the hose to the
disposal system.
The connections to the drainage system must be resistant to acid condensation and always allow
the condensate produced by the boiler to drain.
If the condensate drain is not connected to the waste water drainage system, a neutralizer must
be installed.
B
ATTENTION: THE UNIT MUST NEVER BE OPERATED
WITH THE TRAP EMPTY!
OTHERWISE THERE IS DANGER OF SUFFOCATION
DUE TO THE EMISSION OF COMBUSTION FUMES.
THE CONDENSATE DRAIN MUST BE CONNECTED
TO THE DRAINAGE SYSTEM IN SUCH A WAY THAT
THE LIQUID CONTAINED CANNOT FREEZE.
