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.
• Clean the siphon part section by rinsing it out with
water.
• Fill the lower part with water until about 10 mm below
the upper edge.
• Fasten the lower part again on the condensate water
siphon.
