Hoses used on the low pressure side of a regulator should not exceed what length when connecting to appliances?

When connecting hoses to appliances on the low pressure side of a regulator, safety and performance are key considerations. The maximum recommended length for these hoses is 72 inches. This limitation is in place to ensure that there is minimal pressure drop, which can occur over longer distances. Longer hoses could potentially compromise the appliance's performance and safety by affecting gas flow and pressure.

Using hoses longer than the recommended length could lead to operational inefficiencies and increased risk of leaks or issues with gas ignition at the appliance. Therefore, adhering to the 72 inches guideline ensures that appliances operate effectively and safely, while also complying with industry standards and regulations.
