NOTICE
Flue gas accumulation in the heat generator
If the condensate cannot drain off, it will ac
-
cumulate in the boiler / flue gas collector. The
flue gas can no longer be transported away
without any obstruction.
• Always route the condensate drain with a
downwards slope in such a way that the
condensate is always guaranteed to flow
out without any obstruction.
• Check and clean the siphon, neutralisation
unit (if present) and condensate drain at
least 1x a year.
Discharge into the sewer system
!
WARNING
Germ contamination from the sewer system
If the condensate drain comes into contact
with the sewer system (e.g. drain pipe), the
condensate drain and the heat generator can
be contaminated by germs flowing back from
the sewer.
• The condensate drain
must not
come into
direct contact with the drain pipe (distance
min. 20 mm).

WARNING
Flue gas outlet
If there is no water in the siphon, or too little
water, then flue gas can escape through the
condensate drain. The concentration of flue
gas in the air can represent a fatal hazard.
•
Before commissioning, fill the siphon and,
if present, the neutralisation unit with water.
4.4.2 Installation of the siphon and condensate drain
4.4.2.1 Installation of the condensate drain siphon –
sewer system (standard design)
When installing the siphon and condensate
drain, the project engineering guidelines for
condensate drains must be complied with,
1. Screw double nipple (1) and siphon (2) onto the con-
densate drip tray and tighten securely (connection
must be tight!).

2. Establish the connection (3) from the siphon to the
sewer system (on site).
After installation, before commissioning of the
boiler, the following must be carried out:
•
Check condensate flow.
• Check all connections for leaks:
- Double nipple – siphon
- Siphon – sewer system
•
Check condensate outflow.
