Set-up and installation
C
53
:
– Vertical opening for flue gas outlet
– Opening for supply air inlet into different pressure area possi-
ble.
– Openings must not be installed on opposite walls of the build-
ing
C
63
:
– Connection to a separately approved and marketed flue
gas/supply air system if allowed by national law.
– This allows all other described installation forms to the real-
ised for equipment type C if the conditions of the respective
installation form are met.
– If the dimensions of the system used differ from those
described in this manual (see chap. 4.5.1), a suitable arith-
metical dimensioning verification is required.
– For data on dimensioning calculation, see tab. 15-1.
– Properties and possible applications of the pipe system:
a) Minimum requirements according to chap. 4.5.1 fulfilled
b) Condensate flow into the equipment allowed with single
assignment, not allowed with multiple assignment.
c) Maximum combustion air temperature: 60 °C
d) Maximum allowed flue gas recirculation current under
wind conditions: 10%
C
83
:
– Connection to one or more pieces of equipment to an under-
pressure flue gas system that is part of the building.
– Vertical opening for flue gas outlet
– Air supply feed via associated second pipe
1)
– Opening for supply air inlet into different pressure area possi-
ble.
– Suitable arithmetical dimensioning verification required
because vacuum prevails in the case of the flue gas inlet into
the common air/flue gas system.
– For data on dimensioning calculation, see tab. 15-1.
– Properties and application options of the flue gas system:
a) Minimum requirements according to chap. 4.5.1 fulfilled
(except for pressure class)
b) Condensate flow into the equipment allowed with single
assignment, not allowed with multiple assignment.
C
93
:
– as for C
33
, but
– Connection of the supply air pipe to an existing vertical shaft
(e.g. chimney) that is part of the building.
1)
– The cross-section of this installation shaft must be dimen-
sioned so that the following
minimum distance
must be
maintained
between the external wall of the flue gas line
and the
internal face of the installation shaft
:
– with a rectangular shaft cross-section:
2 cm
– with a round shaft cross-section:
3 cm
.
B
23
:
– Flue gas pipe without flow safeguard - underpressure opera-
tion
– Properties and application options of the flue gas pipe:
a) Minimum requirements according to chap. 4.5.1 fulfilled
– Opening for flue gas outlet to the outside
– Supply air directly from installation room (see chap. 4.2.3)
– If the dimensions of the flue gas pipe differ from those
described in these instructions (see tab. 4-2), a suitable cal-
culated dimensioning verification is required.
– For data on dimensioning calculation, see tab. 15-1.
B
23P
:
– as for B
23
, but underpressure operation
B
33
:
– Connection of more than one piece of equipment to a com-
mon flue gas system (underpressure flue gas shaft)
– Vertical opening for flue gas outlet
– Supply air directly from the installation room (see chap. 4.2.3)
– Suitable arithmetical dimensioning verification required
because vacuum prevails in the case of the flue gas inlet into
the common air/flue gas system.
– For data on dimensioning calculation, see tab. 15-1.
– Parts under overpressure of the connection pipe must be con-
ducted as a concentric pipe system.
B
53
:
– as for B
33
, but connection to associated flue gas pipe
(ROTEX system) including flue gas opening
B
53P
:
– as for B
53
, but overpressure operation
1)
If the air supply pipe was used beforehand as a flue gas pipe or chimney of an
oil or solid fuel furnace, it should be cleaned prior to use as an air supply pipe.
