FA ROTEX GW - 09/2012
4 x Installation
4.2.1 Operation independent of ambient air
Set-up version 1
The ROTEX GW is connected using the concentric LAS
connection line SET GW1 ( 15 50 79.15) to the chimney or an
installation duct.
– The combustible air supply from the outside runs through the
chimney or through an installation shaft.
– The flue gas discharge using a flue gas pipe to the outside
runs through the same shaft as the air supply.
– Minimum distance between flue gas exit and roof ridge:
40 cm.
Set-up version 2
The ROTEX GW is mounted on a wall directly under the roof.
Connection with SET GW2 ( 15 50 79.16).
– The combustible air supply and flue gas discharge run
through a concentric dual pipe.
– The combustible air supply from the outside runs through the
outer ring-shaped gap of the dual tube and the flue gas dis-
charge to the outside runs through the inner tube.
– Minimum distance between flue gas exit and roof surface:
40 cm.
Set-up version 3
The ROTEX GW is not mounted on a wall directly under the roof.
The dual tube for the combustible air supply and flue gas pipe
runs through the roof truss.
– The combustible air supply and the flue gas discharge run
through a concentric dual pipe (as in Installation version 2).
– In the area of the roof truss, the dual pipe for the combustible
air supply and the flue gas duct must be laid through a protec-
tive pipe with sufficient fire resistance or be structurally sepa-
rated from the roof truss.
Set-up version 4
The ROTEX GW is connected using the LAS connection line
SET GW1 ( 15 50 79.15) to the external wall system SET G.
– The combustible air supply from the outside runs through the
ring-shaped gap in the dual pipe, through the outer wall (suc-
tion from below).
– The flue gas discharge to the outside runs through a concen-
tric pipe, through the outer wall and then up to at least 40 cm
over the roof surface. In the external area, the outer air gap
serves as heat insulation for the flue gas pipe.
Set-up version 5
The ROTEX GW is connected to a certified and CE-marked
horizontal wind protection device, that also provides inlet of the
combustion air and outlet of the flue gas to the open air, via
associated concentric connectors.
– The flue gas outlet must be located at least 40 cm above roof
level.
Set-up version 6
Multiple applications: The ROTEX GW is connected to a
certified and CE-marked air-fuelgas system via appropriate
concentric connectors.
– The combustible air supply from the outside runs through the
chimney or through an installation shaft.
– The flue gas discharge using a flue gas pipe to the outside
runs through the same shaft as the air supply.
Several units can be connected to this flue gas line, if
a) calculated evidence is produced that, when the flue gases
enter the common flue gas line there is a negative
pressure (in accordance with EN 13384) and
b) fire propagation between the storeys is prevented by
automatic isolator devices or other verifiable appropriate
measures.
– Minimum distance between flue gas exit and roof ridge at
least 40 cm.
Set-up version 7
The ROTEX GW is connected via associated concentric
connectors to its own or common (as per set-up variant 6)
certified and CE-marked flue gas installation.
– Combustion air inlet from outdoors via the wind protection
device in the external wall. The inlet air connected to this must
be connected adequately close to the associated concentric
connector.
– Flue gas dissipation to the outside using a suitable chimney
or a flue gas line that runs within it. With a multiple occupa-
tion flue gas system the requirements as per set-up vari-
ant 6 apply.
Information for installation in garages
The ROTEX GW is principally suited for installation and operation
within garages.
Requirements:
Requirements:
– Year-round frost free ambient air temperatures,
– Operation independent of ambient air,
– A durable instruction manual placed in a very visible place
near the unit,
– The construction must include a protective device against
mechanical damage (vehicle!) for the entire system (e.g.
bracket or deflector).
– Creation, within the building, of a suitable device to prevent
flammable material being placed on top of the unit housing
(e.g. sheet metal cladding up to the ceiling in the room).
ROTEX recommends the use of the gas condensing
boiler in room-air independent operation with a
concentric flue gas/air inlet. If possible, choose this set-
up!
In the event of limited room-air independent operation
(separate flue gas/ air inlet) and in the event of room-air
dependent operation, the installation room must have a
ventilation opening of at least 150 cm
2
to the outside.
This reduces the overall energy efficiency of the
building in the framework of the European Guideline
2010/31/EU:EPBD.
With equipment erection in residential rooms, only one
of the set up variants 1 to 7 is permissible.
If the wall penetration is at a height of less than a meter
above the ground, ROTEX recommends introducing
the combustion air through a separate intake air pipe
(installation height: about 2 m). W8 ZR, 15 50 79.00
