What is the typical manifold (burner) pressure delivered to a standard residential natural gas appliance?
a.About 11 inches water column
b.About 3.5 inches water column
c.About 2 psi
d.About 14 inches water column
Explanation
A standard natural gas appliance operates at a manifold pressure of about 3.5 inches water column, set by the appliance regulator. Propane appliances by contrast typically run near 10 to 11 inches water column. Manometer readings in inches of water column are how these low pressures are measured and verified.
