the delivery pressure at the exhaust pipe
socket of the boiler does not rise above the
specified value (see chapter 3.8)
Therefore, before installing the boiler, check if
these two conditions are complied with or can be
fulfilled.
Local regulations must be taken into account when
connecting to drinking water networks!
3.4
Return flow boost
The return flow temperature must not drop below
65 °C! The position of the return flow connection is
shown in chapter 5.2 (Connections). The return
temperature increase is controlled to 70 °C by the
boiler itself. This requires an
electronic
mixer unit!
A thermal bimetallic cartridge is
NOT
permitted,
otherwise the boiler cannot work properly!
Attention:
Corrosion damage caused by too low return
temperature is not covered by warranty.
The boiler return sensor is already factory-
fitted on the boiler return as a contact sensor.
3.5
Installation, boiler room and
supply air
In the case of fireplaces, the building regulations of
the respective countries apply with regard to the
structural requirements for boiler rooms and their
ventilation. FAVOR Sufficient fresh air supply to the
heating room so that the fresh air required for
operation of all installed firing systems can flow in
and no lack of oxygen occurs to protect the
operator!
To meet this requirement, we recommend a supply
air cross-section of 400 cm2 for all boiler sizes up
to 50 kW. For rectangular openings, the aspect
ratio should not be greater than 1.5:1; for grids, an
appropriate allowance should be made so that the
free cross-section meets the above requirement.
Requirements for an installation / heating
room:
Closed room with ventilation openings that comply
with the respective legal requirements. The room
must have a lockable door which must be kept
permanently closed.
3.6
Installation location
Ensure horizontal alignment. For unhindered
operation and maintenance of the boiler system, it
is essential that at least one side
(A or D)
has a
free passage width of at least
85 cm (see
illustration)
. Sufficient bright electrical lighting
must be provided for the display and safety
devices, the operating instructions and the access
routes. Flammable objects which are not required
for the operation or maintenance of the boiler
system must not be stored in the boiler room or
installation site (observe building and safety
regulations, state building codes!).

Transport tot he boiler room
If a crane is available for transport, the boiler can
be inserted by means of transport hooks and load
chain. Another option is to transport the boiler on
the transport pallet using a forklift truck, making
sure that the forks are long enough to prevent the
boiler from tipping over. If the space is too narrow,
the boiler can easily be transported on rollers on
flat surfaces after dismantling the transport pallet.
If stairs have to be crossed, all doors can be
dismantled (weight saving, see assembly
instructions on page 24). During transport, it is
essential to pay attention to the floor insulation
mounted on the underside so that it is not damaged
or slipped out!
3.7.1
Checks after transport
The following points must be observed after
transport to the boiler room:
Correct position of the combustion chamber
bricks.
The combustion chamber bricks should not be
removed during transport of the boiler.
Attention:
Be careful when handling the combustion chamber
bricks - danger of breakage!
