If it ever proves necessary to neutralise the condensate
that forms in the flue gas stack, connect the condensate
drain fittings of the boiler and flue gas stack together
using a ‘T’ union and connect the leg of the ‘T’ to the inlet
of the N2 or neutralisation unit.
b
Make sure that you tighten the hose clamps suffi-
ciently.
NEUTRALISATION UNIT TYPE HN2 (WITH PUMP)
HN2 neutralisation units are designed for systems with
boiler condensate drain pits located at a higher level
than the boiler condensate drain fitting.
The pump is controlled by an electrical level switch in
the HN2 neutralisation unit. Refer to the instructions pro-
vided to connect these neutralisation units up electrically.
These units have an electrical protection rating of IP44.

All connecting hoses must be kept as straight and as
short as possible. Any curves or sharp bends can lead
to the hoses becoming clogged and can therefore pre-
vent proper condensate discharge.
NEUTRALISATION UNIT TYPE N2
N2 neutralisation units are designed for systems with boiler
condensate drain pits located at a lower level than the boiler
condensate drain fitting. These neutralisation units do not
require any electrical connections.
The inlet fitting (A) of the N2 neutralisation unit (the lower
fitting) must be connected to the boiler condensate drain
fitting using the flexible hose (C) supplied. This condensate
drain hose is specially made to prevent combustion fumes
escaping into the atmosphere.
The outlet fitting (B) of the neutralisation unit (the top fitting)
must be connected to the boiler room’s waste water drain pit
using another section of flexible hose (not supplied).
b
The boiler room’s condensate drain pit must be located
at a lower level than the fitting (B) on the neutralisation
unit.
