Step 8: Adjust MIN Speed
Instructions:
 To adjust the burner for partial load you have to be in the Service programme
in Service point c27/c38 ="Nmax" (!) the value of the MIN speed setting (only
used while measuring the gas exhaust values at partial load!).
 Instructions for adjusting the Service point are similar to those in Step 6.

Step 9: Start burner and measure the gas exhaust values at
MIN speed
Instructions: Start unit and measure gas exhaust values
 When adjusting the convection burners  Start the Convection programme ;
When adjusting the steam generator burners  Start the Steam programme
.
 The burner blower runs at the Start speed. After successful ignition of the
burner, it is automatically decreased to MIN speed.
 Measure the gas exhaust values, after 1 minute read the measured value and
check with the CO
2
value on Chart 5 "Gas exhaust value @ Min “.
 Record the CO
2
and CO values. At a CO value > 500 ppm switch off the unit
and check the cause of the excessive CO value.
