When using as measured O
2
percentage, and CO

:
Where: CO
AFppm
= Carbon monoxide, air-free ppm
CO
ppm
= As-measured combustion gas carbon monoxide ppm
O
2
= Percentage of oxygen in combustion gas, as a percentage
CO
2
= Percentage of carbon dioxide in combustion gas, as a percentage
The model P-5100 does not produce excessive concentrations of CO if adjusted properly.

Fuel Pressure Adjustment
Once the air is adjusted, and if the fuel system and burner appear to be operating correctly,
the fuel pressure may be slightly adjusted to match the measured V
set
voltage with the
required V
set
value. Use
Figure 21
to determine how much to adjust the fuel pressure.
Example:
Required V
set
= 6.83 V
Measured V
set
= 6.5 V
Difference = +0.33 V
