3.12 ONSITE MEASUREMENT OF THE
COMBUSTION EFFICIENCY
3.12.1 ENABLE THE CALIBRATION
FUNCTION
ATTENTION!
Function reserved exclusively to Authorised Service
Centres.
ATTENTION!
is function is explained in chapter 6 (Generator
control) of the HSCP installation and maintenance
manual.
3.12.2 POSITIONING THE PROBES
In order to determine the combustion eciency, the following meas-
urements must be taken:
- measure the combustion air temperature
- measure the ue gas temperature and content of CO
2
withdrawn from
the hole 2.
Take the specic measurements with the generator at full speed (see
Par. 3.12.1).
All boilers leave the factory calibrated and approved,
nevertheless, if the calibration conditions need to be
changed it is necessary to re-calibrate the gas valve.
ATTENTION!
Remove cap 2, attach the red cap 3 to the ue point 1.
Place the CO
2
analysis probe 4 in the hole on the cap.
Once the measurement has been made, take the cap
out and use the relative cap 2 to close the ue exhaust
point back up.
