Question: 1 / 400

For a gas appliance to function properly, it must receive what?

At least the maximum manifold pressure

Exactly the average service pressure

A specified minimum manifold pressure

For a gas appliance to function effectively, it requires a specified minimum manifold pressure. This pressure is critical because it ensures that the appliance operates efficiently and safely. The manifold pressure is the pressure at which the gas is delivered to the appliance's burner. If the pressure falls below this minimum threshold, the appliance may not produce enough flame to function correctly, leading to incomplete combustion, poor performance, and potential safety hazards.

Maintaining the correct manifold pressure is crucial for achieving optimal performance and efficiency in gas appliances. While some situations may allow for operating above the minimum pressure, it is the minimum level that guarantees sufficient gas flow for safe and effective operation. Understanding the specific pressure requirements for different appliances is essential for gas fitters to ensure compliance with safety standards and operational guidelines.
