Parallel boiler connection
Theboilercomesasstandardwitha
parallelconnectionfortheuegas
outlet and air supply system.
For the air supply opening (1) diameter
andtheuegasoutletconnection(2),
seetablebelow.
Theairsupplychannelcanbe
connected to it, or, if it involves an
“open device” (Drainage category B),
anairlterisrecommended.
Concentric boiler connection
Theboilers60-70-100-120-140canbe
converted into a concentric connection
using the parallel/concentric adapter
100/150 (optional) and carrying out the
following tasks:
- Open and remove the frontal
panel and the top panel (follow the
instruction on page 42.
- Lift the parallel connection.
- Disconnect the main switch 230V
connection and remove it.
- Replace the parallel connection
with parallel concentric adapter.
- Connectandtthemainswitch
230V according to previous
conguration.
The air supply opening has a diameter
of ø150mm.
Theuegasoutletconnectionhasa
diameter of ø100mm.
Theuegasoutlet-/airsupplysystem
is then connected to the concentric
connection component.
Installation
Connections
Air- / ue gas ducts for individual boilers
TheTRIGONLPLUS-boilerscanbe
usedbothinan“open”andin“closed”
system.
Open system
Therequiredcombustionairistaken
from the immediate environment
(boilerroom).Forthispurpose,please
complywiththeapplicableboilerroom
ventilation regulations.
WhenusingboilercategoryB23and
B33asan‘openboiler’,theprotection
degreeoftheboilerwillbeIPX0D
instead of IPX4D.
Anairlteroragridisrecommended
ontheairintakeoftheboiler(available
as an accessory on pages 15-17.
Closed system
Therequiredcombustionairissucked
in from the outside through a channel.
Thisimprovesinstallationpossibilities
withinabuilding.Ingeneral,outsideair
iscleanerthanairfromtheboilerroom.
When the boiler is op erational,
it produces a white plume of
condensation. This condensation
plume is harmless but may cause
some inconvenience, particularly
in the case of wall terminal. As a
result, roof terminals are preferred.
In a closed installation, roof
terminals should be at the same
height preventing ue gas from
being sucked in by the other boiler
(recirculation). Outlets in recesses
and near erected walls may also
bring about ue gas recirculation.
Recirculation has to be prevented at
all times.
For installation in UK please refer to
installation guidance in BS6644 and
IGE UP10.

Fan settings correction
By setting parameter (21-2-4) it is
possibletocompensateforahigher
uegaspressuredi󰀨erence.Itis
required to have a pressure drop
calculationoftheapplieduegas
system.
According the calculated pressure
drop, the correct value for parameter
(21-2-4)hastobechosenfromthe
tablebelow.
For setting parameters see the
