Setting Combustion - CleaverBrooks CFC-500 Operation, Service And Parts Manual

Section 4 — CFC Commissioning

7. Setting Combustion

Note: A Combustion Analyzer is required to properly set up the
Model CFC burner. Do not attempt to fire and adjust the
burner without this equipment.
Note: Ensure boiler is filled with water prior to burner startup.
The burner does not have need of linkages for fuel/air adjustment,
nor is a separate manual-auto switch provided for burner
positioning. All firing rate adjustments are accomplished via the CB
Falcon Control. Setting combustion will require manually
modulating the burner via the CB Falcon from low fire to high fire
two or more times to ensure a consistent air/fuel ratio.
Manual Modulation - use the procedure below to change the burner firing rate manually.
1. On the CB Falcon Operation screen, press the
Firing rate display in the Modulation section.
3. Press <Clear> to clear the current value.
4. Enter the desired RPM setting using the numeric
keypad (refer to Table 4-2, Fan Speed Settings).
5. Press <OK>. The display will return to the Opera-
tion screen and the burner will modulate to the cho-
sen firing rate.
4-22
NOTE: Install the combustion
analyzer probe as close as possi-
ble to the boiler vent connection.
Sampling too far from the boiler
vent can produce false readings
due to air diluting the flue gas.
2. A numeric keypad will appear,
showing the current firing rate.
