Notes on System Integration
Chimney
Exhaust Venting

Condensate Lines

Condensing Boiler
In condensing boilers, residual heat is
extracted from the exhaust gases
through cooling and condensation, and
subsequently fed back into the heating
system. This ensures a high degree of
efficiency and low energy consumption.
Chimney Notes
Exhaust vents must be installed in a
shaft compliant with DIN 18160 / Part 1.
Prior to assembly of any condensing
boiler, always check the exhaust
vent system.
Dimensions shall be applicable to the
use of a polypropylene (PPS) exhaust
system pursuant to DN 110/150 only.
The low exhaust temperatures require
commercially available exhaust vents
applicable to condensing boilers.
Examples:
-
Chimneys resistant to moisture
-
Interior shells resistant to condensate
-
Certified exhaust vents
-
Diameters of connectors (sleeves)
must be taken into consideration for
minimum shaft diameters
Installation example for separate
condensate discharge from exhaust
vent.
Condensate
The connection of the condensate
discharge (behind boiler) must be
sloped into the discharge line. It must
also be protected against freezing.
Exhaust venting via
-
exhaust line certified and checked
according to DIBT (Germany), VKF
(Switzerland), or ÖTZ (Austria)
-
chimney
Conduit pipes and sections must be
-
freely accessible and checkable from
outside the shafts, and must be pro-
tected from freezing;
-
rear ventilated from inside the shafts
Exhaust vents must be
-
resistant to moisture
-
suitable for exhaust temperatures
below 40°C
-
suitable for excessive pressure
Recommendation:
Accessory set: Exhaust vents
Condensate pipes must not be
installed in fixed position.
The condensate is collected in a funnel
and discharged into the sewer system.
Recommendation:
Accessory: Neutralizing device
Comply with work sheet ATV A 251.
DANGER:
Danger of poisoning! If the
siphon is not full of water, or with
open connections, flue gases arising
can put people in mortal danger.
Exhaust Vents
Ventilation / exhaust system
Applicable local regulations must be
complied with when installing the
exhaust system.
The TRIGOL L compact heating center
must be operated with an approved
exhaust system only. Customer
supplied exhaust systems must be
resistant to moisture, corrosion, and
condensate, and must comply with all
static and operational requirements.
The fireplace opening must permit an
unencumbered exiting of the exhaust
gases (fireplace cap is not recom-
mended).
The connection between fireplace and
TRIGON L must be sloped (3%) so
that the accumulating condensate may
flow back from the exhaust pipe. This
connection should have as few bends
as possible. The exhaust vent shall
have inspection openings pursuant to
government regulations. The use of a
room air independent exhaust system
is possible.
Exhaust pipes
Horizontal pipe layout must be avoided
in order to avoid any settling of conden-
sate. You must ensure that the various
components are connected and sealed
tightly.
Any assembly shall use 45° bends.
Vertical parts shall be fastened with
straps.
