Maintenance And Disposal - Riello N2 Mode D'emploi

Types HN2 - HN3
The inlet fitting (A) of the neutraliser (the lower fitting)
must be connected to the boiler condensate drain fitting
using the outlet hose (C) supplied. This condensate
drain hose is specially made to prevent combustion
fumes escaping into the atmosphere.
The outlet fitting (B) of the neutraliser (the top fitting)
must be connected to the boiler room's waste water drain
pit using another section of flexible hose (not supplied).
b
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 prevent proper condensate discharge.
If it ever proves necessary to neutralise the condensate that forms in the flue gas stack, connect the condensate drain fit-
tings of the boiler and flue gas stack together using a 'T' union and connect the leg of the 'T' to the inlet of the neutraliser.
b
Make sure that you tighten the hose clamps sufficiently.
Maintenance should be performed on the neutraliser at
regular intervals, as needs require (but at least once a
year) based on the characteristics of the installation.
Check the level of the granules in the granulate box. The
minimum level is 15 cm below the top of the box.
The initial charge of neutralisation granules should be
enough to last for at least one season of boiler function-
ing even at the maximum rate of condensate formation.
Avoid topping up the granules or only partly replacing
them.
If deposits form on the surface of the neutraliser, the
granules must be replaced completely.

(*) The height difference the pump can overcome is equiv-

resistance offered by the drain hose.

MAINTENANCE AND DISPOSAL

DISPOSAL
The dolomite granules are filtering material and can be
disposed of as household waste, unless this is forbidden
by national or local regulations.
