NOTES ON TABLES:
•
Combustion Air Shutter Setting is the position of the air shutter from 0 to 90 degrees.
•
O
2
% is the percentage of oxygen measured in flue products.
•
Manifold Pressure is the gas pressure measured from the pressure tap on the back of the
SKP25 regulating gas valve. (Figure 8 ahead)
•
Minimum Inlet Pressure is the minimum gas supply pressure to the gas train necessary to
obtain the desired flow rate. Inlet supply pressures up to 48 in w.c. are permitted.
