Draining the condensate
9
Always maintain a slope “i” of over 3° and ensure
that the diameter of any hose used is greater than
that of the boiler’s own condensate drain pipe .
9
The connection to the waste water drain must be
made in compliance with national and local legi-
slation and standards.
9
Fill the siphon with water before you start up the
boiler to prevent products of combustion escaping
into the room during the first few minutes of boiler
functioning.
9
Condensate from the boiler and from the flue
should be channelled to the same drain point .
9
The surface on which the boiler stands must be
perfectly horizontal and flat over the entire area of
the boiler frame in order to avoid condensate drai-
nage problems.
9
Any condensate neutralisation units deemed ne-
cessary may be connected downstream from the
siphon. Evaluate the neutralisation unit after one
year of operation to estimate the duration of the
neutralisation charge. The total duration of the
charge can be estimated from the level after one
year.
