Why is running pressure important?

Running pressure is crucial because it represents the actual pressure supplied to the burners while the equipment is in operation. This measurement is essential for ensuring that the appliances are functioning efficiently and safely. When the running pressure is within the manufacturer's specified range, it assures the correct mixture of air and gas, which leads to optimal combustion and performance.

If the pressure falls outside the recommended range, it can lead to incomplete combustion, creating inefficiencies, or even unsafe operating conditions. Monitoring running pressure helps technicians determine if the system is operating correctly and if any adjustments or repairs are needed to maintain safe and effective operation. This aspect underlines why the concept of running pressure is central to safe and efficient gas appliance operation.
