Page 28: Condensate Evacuation
INSTALLER INSTALLER Condensate evacuation Before commissioning, fill the siphon with water up to level “L” in line with the top fitting. TAU N condensing boilers produce a flow of condensate that varies according to operating conditions. The maximum hourly production of condensate is shown in the technical specifica- tions table for each individual model. -

Any curves or sharp bends can lead to the hoses becoming clogged and can therefore prevent proper condensate discharge. If it is necessary to neutralise condensation produced in the chimney, we recommend to connect the condensation drains of boiler and chimney using a tee connector and then get them to the neutraliser inlet.
