Exhaust Measurement
On account of the construction-dependent design of the
exhaust connection (connection nozzle with secondary
air openings), it is not possible to perform a correct ex-
haust analysis in a conventional manner in the exhaust
pipe behind the exhaust connection.
For the performance of the exhaust analysis the sensor
of the exhaust-measurement device must be placed in
the centre of the pipe socket of the heat exchanger.
The measurement sensor is placed through the appro-
priate lateral secondary air opening in the exhaust con-
nection in the existing measurement opening in the pipe
nozzle of the combustion chamber (see drawing below).
