SECTION 3 CAL-IOM-2013-1001 OPERATION
3-7
5. Using test  re sheet, enter the rpm value (light o ) in the Manual Firing
Rate box.
6. Once the rpm value is entered, tap OK.
7. Return to the status screen.
8. Turn the local/o /remote switch to the local position.
9. Once burner has started and  ame signal has been veri ed, return to the
Manual Firing Rate box.
10. Increase the  ring rate in 500 rpm increments until high  re rpm value
from the factory test  re sheet is reached.
 At each point, check combustion. CO2/CO should remain constant
throughout  ring range. Monitor inlet gas pressure during combustion.
11. Once the high  re rpm setting is reached, make adjustments on the
gas ratio valve  ow rate to match factory test  re settings. The  ow rate
adjustment requires a 3mm hex wrench.
NOTE:  Turning the screw counterclockwise increases gas  ow; clockwise
decreases gas  ow.
NOTE:  The acceptable combustion range of CO
2 is 8.0% to 9.8%. To
maintain NOx < 20%, set combustion to approximately 8.4% CO
2. Site
-speci c factors may contribute to the determination of the appropriate
combustion range of CO
2, and other combustion parameters.
NOTE:  Combustion changes are made at high and low  re only, as the gas
ratio valve has a 1:1 ratio.
12. Manually decrease the  ring rate by 500 rpm increments. Observe
combustion down to the low  re rpm setting (minimum) on the factory
test  re sheet. If required, low  re combustion may be altered by adjusting
the o set adjustment screw with either a Torx®T40 or a 5mm hex wrench.
NOTE:  Turning the screw counterclockwise decreases gas  ow; clockwise
increases gas  ow.
13. If changes are made (at either high or low  re), recheck the entire range.
14. Before leaving the Firing Rate screen, tap Automatic  ring rate control. Do
not leave the unit in the Manual in Run mode.
