4.6. Gas flue analysis
During the installation the technician is required to analyse the combusted gas. To do this a
portable analyzer fitted with a probe and printer is needed. It is advisable to prepare an
extension pipe in order to avoid damages to the probe, a cause of the high temperature of
the gas (about 400 ° C).
During the setup procedure wizard (described in section 4.1), it is recommended to keep
the engine speed (minimum or maximum) for 2-3 minutes and only then insert the probe for
the acquisition of CO2 and CO values. Wait until the measure has stabilized (about 1
minute).
-
The gas analyzer should be calibrated and checked periodically to make precise
measures.
-
Recommended analyzer: Testo 327-2.
