It must be possible to inspect the lining duct.
If condensate from a plastic or stainless steel pipe section can flow back
to an aluminium part in the flue gas outlet, this condensate must be dis
charged via a collector before it reaches the aluminium.
With longer lengths of aluminium flue gas outlet pipes, relatively large
quantities of corrosion products flowing back out of the outlet pipes to
gether with the condensate must be taken into account the first time.
Clean the siphon of the appliance regularly or install an extra conden
sate collector above the unit.
Make sure that the flue gas outlet pipe towards the boiler has a sufficient
gradient (at least 50 mm per metre) and that there is a sufficient conden
sate collector and discharge (at least 1 m before the outlet of the boiler).
The bends used must be larger than 90° to guarantee the gradient and a
good seal on the lip rings.

Condensate drain
Because the flue gases condense in the discharge system, condensed
water develops and must be discharged. As a rule of thumb, we anticipate
a maximum of 1 litre of condensed water per m
3
of natural gas consumed.
In practice, this amounts to:
approx. 17.5 litres of condensate per hour for the MCA 160
