Note
It is not possible to set the max. heating output for
type B1GA-11.
A limit can be set on the maximum heating output for
heating mode
. The limit is set via the modulation
range.
Note
The flow rate must be checked before the max. heat-
ing output can be adjusted. Ensure adequate heat
transfer.

Leak test on balanced flue system (annular gap check)
A
Fig. 20
A
Combustion air aperture
For balanced flue systems tested together with the
heat generator, there is no requirement for a tightness
test (overpressure test) during commissioning by the
flue gas inspector.
In this case, we recommend that a simple tightness
test is carried out during system commissioning. For
this, check the CO
2
or O
2
concentration in the combus-
tion air at the annular gap of the balanced flue pipe.
If the CO
2
concentration is less than 0.2 % or the O
2
concentration is greater than 20.6 %, the flue pipe is
deemed to be sufficiently gas-tight.
If actual CO
2
values are greater or O
2
values are lower,
then pressure test the flue pipe with a static pressure
of 200 Pa.
!
Please note
If the test port is not sealed, combustion air is
drawn in from the room.
After the tightness test, re-seal the test port with
the plug.
