c. Using a combustion analyzer with the capability to
read carbon dioxide (CO
2
) and carbon monoxide
(CO), place the probe into the combustion test
port. See Figure 9.2.
d. Manually set the boiler to Maximum power by
entering the System Test Mode. See Appendix C,
Installer Menu.
• Verify that the fan speed indicated is within 30
rpm of the maximum power fan speed in
Table 12.2.
• Verify that the CO and CO
2
emissions are
within the parameters specified in Table 5.4.
e. Manually set the boiler to Low Power by entering
the System Test Mode. See Appendix C, Installer
Menu.
• Verify that the fan speed indicated is within
100 rpm of the Low Power fan speed listed in
Table 12.2.
• Verify that the CO and CO
2
emissions are
within the parameters specified in Table 5.4.
f. If the values in either of these instances falls outside
the parameters listed in Table 5.4, turn off the
boiler and contact your PB Heat representative. For
best results, the value should be set for the middle
of the range (9% for Natural Gas and 10% for
LP Gas).
g. Be sure to set the System Test mode to Off so that
the boiler will modulate correctly in accordance
with the load.
h. After removing the analysis probe from the vent
pipe, insert a PVC or Stainless Steel pipe plug into
the test port. See Figure 9.3.
i. Record the combustion readings on the “Start-up
Combustion Record” in Appendix D. It is very
important to record all of the information
requested on the sheet for follow up and
troubleshooting.
