approved gas installer. Before beginning the work, the gas shut-off
device and the shut off valves of the hot water should be closed.

10.2 Replace air-vent
A defective air-vent must only be replaced with an original spare
part; this guarantees an optimum de-aering!
Caution!The boiler water has to be drained before dismantling of
the quick-de-aerator, as otherwise water will leak out!
10.3 Condensate siphon
The condensate syphon should be cleaned every one to two years.
For this, loosen the upper screw connection at the siphon and pull
the siphon downwards. Remove the siphon complete with hose out
of the boiler, dismantle and rinse with clean water. Assemble the
siphon in reverse order.
At the same time, the flue gas collecting sump should be checked
for soiling and if needed should be cleaned (rinsed).
