1.7.5 Condensate water drain
NOTE!
The condensate water collecting in the gas
boiler and possibly in the flue gas line must be
drained. Local regulations must also be noted.
When shorter aluminium flue-gas systems are used
CAUTION!
If the flue gas adapter is made of aluminium,
the sealing cap (fig. 12, item 1) MUST NOT be
removed.
There is no integrated condensate water outlet in the flue gas
adapter of the aluminium exhaust flue.
The condensate water from the exhaust flue flows via the gas
boiler and into the boiler's odour trap (syphon, see fig. 10).
When longer aluminium flue-gas systems are used
CAUTION!
If the flue gas adapter is made of aluminium,
the sealing cap (fig. 12, item 1) MUST NOT be
removed.
There is no integrated condensate water outlet in the flue gas
adapter of the aluminium exhaust flue.
The condensate water from the exhaust flue flows via the
external condensate water outlet with odour trap
(syphon, see fig. 11).
This additional component is required:
– from 10 m expanded overall length of exhaust flue with
800 Series to boiler size of 24 kW or
– from 5 m expanded overall length of exhaust flue with type
800 – 29, 800 – 43 and 800 – 60.
Subject to modifications resulting from technical improvements !
