DRAINING THE CONDENSATE
ELECTRICAL CONNECTIONS
b
Always maintain a slope “i” of over 3° and ensure
that the diameter of the condensate drain hose is
always greater that of the drain fitting on the boiler .
b
Check and clean the condensate drain siphon and
pipes at least once a year, as instructed in “Cleaning
the condensate drain siphon” section.
b
The connection to the waste water drain pit must be
made in compliance with national and local legislation
and standards.
b
Condensate from the boiler and that from the flue
stack should be channelled to the same drain pit .
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 neces-
sary may be connected downstream from the siphon.
Evaluate the neutralisation unit after one year of opera-
tion to estimate the duration of the neutralisation char-
ge. 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
THERMITAL
catalogue).
