Danger!
Note that if the boiler is run with an empty
condensate trap there is a danger that fumes
might escape into the room and cause poison-
ing. For this reason, it is important to ensure
that the trap is topped up each time the unit is
cleaned.
• Remove the lower part ( 1 ) of the condensate water
siphon by turning the bayonet catch in anticlockwise
direction.
• Fill the lower part with water until about 10 mm below
the upper edge.
• Refit the lower part of the condensate water siphon.
5.7 Adjusting the pumping capacity
Only in ecoTEC plus:
The capacity of the two-stage pump can be adjusted to
the requirements of the heating system. If needed,
change the setting of the operating mode dependent
pump speed under the diagnosis point “
d.19 ” (see
Section 8.1.2).
5.8 Adjusting the by-pass
The appliances have an adjustable by-pass valve.
The pressure can be adjusted between 170 and 350 mbar.
Approx. 250 mbar is preset (mid-position). The pressure
changes by approx. 10 mbar each time the adjusting
screw is rotated. By turning right, the pressure increases
and turning left decreases it.
