FA ROTEX A1 BO - 10/2007
3.2.3 Ambient air dependent operation
The oil condensing boiler of series A1 BO can also be connected depending on ambient air. The unit suctions the combustible air
from the installation room through the ring-shaped gap in the enveloping pipe.
Set-up version 2
– Combustion air supply from the installation room.
– The flue gas discharge to the outside runs through the chimney or through an installation shaft (as in set-up version 1).
Set-up version 7
The oil condensing boiler is connected to a ceramic chimney by means of
kit A
or
kit C
.
– Combustion air supply from the installation room.
– The ceramic chimney for the flue gas discharge should be humidity-resistant, as specified in DIN and it must have the
corresponding approval (suitability for overpressure operation).
– If the ceramic chimney for the flue gas discharge does not have an approval for overpressure operation, it must be possible
to prove, through a flue gas calculation, that there is a vacuum in the shaft when the flue gas enters.

Factory setting and output range
Ambient air-dependent operation produces air suction noises which raise the operating noise of the boiler.
To reduce the noise, you can use an air supply noise damper (
15 45 77
).
CAUTION!
Lifting or moving the oil condensing boiler by the panels can damage the unit.
• Only lift the gas condensing boiler using the carrying straps provided for this purpose.
The oil condensing boiler will not function without central control unit. The control unit must be ordered
separately in the required model (operation only allowed with ROTEX control unit).
