What is the typical pressure from the gas meter to the appliance?

The typical pressure delivered from the gas meter to the appliance is generally around 6 to 7 inches of water column (wc). This pressure range is standard in residential settings and ensures that gas appliances, such as furnaces, stoves, and water heaters, receive an adequate supply of gas to operate efficiently and safely.

This pressure level allows for optimal combustion while preventing issues that could arise from either too low or too high gas pressure. If the pressure is too low, appliances may not ignite or perform correctly, while excessively high pressure could lead to unsafe operating conditions or damage to the appliances.

The selected range accurately reflects the operational norms in many residential setups, making it critical for ensuring that gas appliances function properly and safely. Knowing this range is essential for anyone involved in the installation, maintenance, or certification of gas systems.
