Section 1
• Inches of water column – example: 7”w.c. • Pressure that is lower than 1 P.S.I. • Approximately 28”w.c. in 1 P.S.I. • Commonly used fuel pressures • 7”w.c. – homes and light commercial/industrial facilities • 14”w.c. – commercial/industrial facilities • 56”w.c. – default pressure CT and CTC AMUs are designed to operate at • 140”w.c. – industrial facilities
• Other pressures to note • Booth pressure – Range: - .025”w.c. to +.025”w.c. Usually set around zero • Burner profile pressure – Range: .5”w.c. to .7”w.c. Optimal pressure is .6”w.c. • Burner manifold pressure – Fuel pressure downstream of the valve train going into the burner.
