A gas vent must extend through what structure and terminate with what?

A gas vent is required to extend through the roof flashing and must terminate with either a listed cap or a listed roof assembly to ensure proper safety and performance. Termination at the roof flashing is crucial to prevent potential leaks and ensure that combustion gases are safely dispersed away from the building.

Using a listed cap or roof assembly at the termination enhances safety by preventing any entry of water or debris into the vent system while also ensuring that the venting is compliant with established safety standards. Listed components are tested and approved for their intended use, providing peace of mind regarding their reliability in venting applications.

Understanding the components and requirements for gas venting is vital for compliance with NFPA 58, and following these guidelines helps to mitigate risks associated with the release of flammable gases. Proper installation and termination practices not only support operational efficiency but also significantly contribute to overall safety in LPG storage and usage.
