3.12.2 - POSITIONING THE SENSORS
To determine the combustion e󰀩ciency
one must make the following measurements:
- measurement of the combustion air temperature
- measurement of the ue gas temperature and content of
CO
2
taken in the relevant hole 2.
Take the measurements with the generator in steady state
conditions (see par. 3.12.1).
ATTENTION!
Remove cap 2, x the red cap 3 to the ue gas
inlet 1. Insert the CO2 analysis sensor 4 in the
cap hole.
Perform the measurement. Remove the cap
and close the ue gas exhaust inlet with the

All boilers leave the factory already calibrated
and tested. However, if the calibration conditions
should be modied, it is necessary to recalibrate
the gas valve.
