Chapter 3: Positioning and installation
Installation version 5.
The boiler is located immediately under the
roof. The combustion air and flue gas are
routed through a concentric twin pipe. Flue gas
is expelled to atmosphere through the inner
pipe; combustion air is drawn in through the
outer annular gap. The distance between the
flue gas outlet and the roof area must be at
least 40 cm. Connection with set L (see Fig.
3.4.3).
Installation version 6.
Like installation version 2, but the balanced
flue pipe is routed through the roof structure.
In this area, the balanced flue pipe must be
routed through a protective pipe with
sufficient fire resistance; alternatively it must
be physically separated from the roof
structure.
The ROTEX GasSolarUnit/GasCompactUnit can
also be installed for open flue operation. In
that case, only the inner flue (plastic
connection Ø 80 mm) of the concentric
balanced flue connection is joined to the flue
pipe. In his case, the boiler will draw in
combustion air from the installation room
through the annular gap of the sleeve pipe.
Note: With this version, the installation room
must provide a ventilation aperture of at least
150 cm
2
unrestricted cross-section.
Information regarding the installation
in garages
The ROTEX GasSolarUnit/GasCompactUnit is
generally suitable for installation and
operation in a garage, subject the the
following conditions being met:
- Balanced flue operation in accordance
with the above installation versions
- Fitting a permanent version of the operating
instructions at an easily accessible point
near the boiler
- On-site creation of a protective measure
against mechanical damage (from vehicles,
for example) - e.g. bull bars or deflectors -
for the whole system.
3.2 Installation options
Generally, a balanced flue connection is
required for the ROTEX GasSolarUnit/Gas-
CompactUnit. A concentric balanced flue
DN 80/125 certified for condensing operation
is available (DIBT - certificate Z-7.2-1051,
Z-7.2-3061, Z-7.2-3062).
The GSU/GCU can be installed in 4 different
ways (see Fig. 3.2.2).
Installation version 1.
The chimney or service duct delivery the
combustion air from outside. The flue gas is
routed through the same duct in a certified
flue (ø 80 mm) to above the roof and to
atmosphere. The distance between the flue
gas outlet and the roof ridge must be at least
40 cm. The boiler is connected with the
balanced flue pipe set H or K (see Fig. 3.4.1 to
3.4.3).
Installation version 4.
The boiler is connected with the set H or K
(see Fig. 3.4.1 to 3.4.3) to the external wall set
G.
This concentric pipe is routed through the
external wall to the outside and then at least
40 cm above the roof. For the external part, the
outer air gab acts as thermal insulation for the
flue pipe. The combustion air is drawn from
the outside via the annular gap of the
concentric twin pipe.
If the wall outlet is less than 1 m above ground
level it is recommended to supply the
combustion air through a ventilation pipe at a
height of at least 2 m.

3.1 Delivery
Caution: Risk of tipping
In their delivered condition,
ROTEX GasSolarUnit/Gas-
CompactUnits are top-heavy. Tipping over

damage to the equipment. Handle with
care.
The ROTEX GasSolarUnit/GasCompactUnit is
delivered on a pallet. Any level transport aids,
such as a pallet truck or forklift truck, are
suitable for transporting the unit. The standard
