What is the LP gas pressure supplied to the appliance gas valve?

The LP gas pressure supplied to the appliance gas valve is typically in the range of 11-13 inches of water column (WC). This specification is crucial because it ensures that the gas appliance operates safely and efficiently. Proper calibration of the gas pressure is fundamental to the combustion process in gas-fired appliances, allowing for optimal performance and reducing the risk of hazards such as incomplete combustion, which can produce carbon monoxide.

In many gas appliances, maintaining this pressure range helps ensure that the gas mixes appropriately with air for efficient burning, producing adequate heat while minimizing emissions. Operating outside this recommended range can lead to issues such as poor heating performance or increased emissions.

Understanding this pressure specification is essential for technicians and installers to maintain compliance with safety standards and ensure the longevity and reliability of gas appliances.
