What is the manifold pressure of natural gas typically measured in?

The manifold pressure of natural gas is an important measurement, typically indicating the pressure at which natural gas is delivered to appliances from the gas supply system. The correct answer reflects the standard pressure range typically associated with residential gas systems.

Natural gas systems often operate at a pressure that ensures efficient combustion and reliable operation while remaining safe for the appliances that use the gas. The range of 3 to 4 inches of water column (wc) is widely accepted for manifold pressure in residential applications, providing enough pressure for proper appliance functioning without exceeding safety thresholds.

Understanding this range is crucial for technicians to ensure that gas appliances operate effectively and safely, as pressures that are too low can lead to inefficient combustion, while pressures that are too high can pose safety risks or damage the appliances.
