IX. System Start-up
(continued)
WARNING
Asphyxiation Hazard. If the throttle is very far out of adjustment on the “rich” (counter-clockwise) side,
the boiler burner may be running at 0% excess air or even with air deficiency. Operating the boiler in this
condition may cause property damage, personal injury or loss of life.
Under these conditions most combustion analyzers used in the field will show 0% O
2
and a very high (well
over 1000 ppm) CO. Combustion readings will also appear to be unresponsive to throttle adjustment.
If the boiler appears to operate under these conditions, shut down the boiler and follow instructions in
Paragraph S “Correcting Throttle Screws Mis-Adjustment. Then, use a combustion analyzer to verify and
adjust O
2
(or CO
2
) and CO to values shown in Table 22 for natural gas or Table 23 for LP gas.
