OPERATION
3-7
5. Using test fi re sheet, enter the rpm value (light off ) 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/off /remote switch to the local position.
9. Once burner has started and fl ame signal has been verifi ed, return to the
Manual Firing Rate box.
10. Increase the fi ring rate in 500 rpm increments until high fi re rpm value
from the factory test fi re sheet is reached.
 At each point, check combustion. CO2/CO should remain constant
throughout fi ring range. Monitor inlet gas pressure during combustion.
11. Once the high fi re rpm setting is reached, make adjustments on the
gas ratio valve fl ow rate to match factory test fi re settings. The fl ow rate
adjustment requires a 3mm hex wrench.
NOTE:

Turning the screw counterclockwise increases gas fl ow; clockwise
decreases gas fl 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
-specifi 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 fi re only, as the gas
ratio valve has a 1:1 ratio.
12. Manually decrease the fi ring rate by 500 rpm increments. Observe
combustion down to the low fi re rpm setting (minimum) on the factory
test fi re sheet. If required, low fi re combustion may be altered by adjusting
the off set adjustment screw with either a Torx®T40 or a 5mm hex wrench.
NOTE:  Turning the screw counterclockwise decreases gas fl ow; clockwise
increases gas fl ow.
13. If changes are made (at either high or low fi re), recheck the entire range.
14. Before leaving the Firing Rate screen, tap Automatic fi ring rate control. Do
not leave the unit in the Manual in Run mode.
