If the pilot light goes out when the burners attempt to ignite, what might be wrong with the pressure regulator?

When the pilot light goes out during the burner ignition process, a clogged vent fitting in the pressure regulator could be a contributing factor. The vent fitting allows the regulator to sense the pressure within the gas system. If it becomes obstructed, the regulator may not function properly, leading to inadequate gas pressure reaching the burners. Therefore, the gas flow may be irregular or insufficient, causing the pilot light to extinguish when the burners are ignited.

Additionally, understanding that the pressure regulator must maintain a consistent pressure to ensure safe and effective operation of the equipment is crucial. If the vent is blocked by grease, it compromises the regulator's ability to perform its duty, which can directly impact the reliability of the pilot light and overall burner function.
