What should the LP gas pressure supplied to the gas valve typically be?

The typical LP gas pressure supplied to the gas valve is usually within the range of 11-13 inches of water column (W.C.). This pressure range is essential for ensuring that the gas appliance operates efficiently and safely. The correct pressure allows for optimal combustion, which is crucial for heating systems to function properly. If the pressure is too low, the appliance may not receive enough fuel to operate effectively, leading to poor performance or incomplete combustion. Conversely, if the pressure is excessively high, it can result in flames that are too intense, which may cause damage to the appliance, increase emissions, and pose a safety hazard.

Maintaining the LP gas pressure within this specified range is typically in line with manufacturers' recommendations and regulatory standards, which aim to maximize efficiency and safety in gas-fueled heating applications.
