What does a clogged vent fitting in a pressure regulator typically cause?

A clogged vent fitting in a pressure regulator typically disrupts the balance of pressure required for proper operation of the gas system. The vent fitting allows excess pressure to escape, helping to regulate and stabilize the flow of gas to the burners. When this vent fitting becomes clogged, it can prevent proper pressure regulation.

This pressure imbalance often leads to insufficient gas flow to the pilot light, particularly when there is an attempt to ignite the burners. If the system cannot supply enough gas or maintain the proper pressure to support combustion, the pilot light may extinguish when the burners try to ignite. Without a steady supply of gas or a stable pressure, the flame cannot remain lit, resulting in the pilot light going out.

This situation highlights the importance of ensuring that vent fittings remain clear and unobstructed, as this will affect the overall operation of gas appliances and their safety. Maintaining these components is crucial for the effective and safe function of commercial kitchen equipment.
