DRAINING THE CONDENSATE
b
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.
b
The connection to the waste water drain must be
made in compliance with national and local legisla-
tion and standards.
b
Condensate from the boiler and from the flue
stack should be channelled to the same drain
point.
b
The surface on which the boiler stands must be per-
fectly horizontal and flat over the entire area of the
boiler frame in order to avoid condensate drainage
problems.
b
Any condensate neutralisation units deemed nec-
essary may be connected downstream from the
siphon. Evaluate the neutralisation unit after one
year of operation to estimate the duration of the neu-
tralisation charge. The total duration of the charge
can be estimated from the level after one year.
b
It is mandatory to use a condensate trap (see the
r
catalogue).
