ing that a new sealing washer is used and correctly
located. Use the spanner flat at the flexible gas line to

Cleaning the condensation water siphon

Fig. 7.9 Cleaning the condensation water siphon
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.
