The minimum height that a chimney must extend above the highest connected equipment draft hood outlet is 5 feet. This requirement is established to ensure proper venting of combustion products and to promote effective draft. When the chimney extends sufficiently above the highest draft hood, it helps prevent downdrafts and ensures that combustion gases are expelled efficiently, reducing the risk of backdrafting into the connected appliances.

This 5-foot extension is crucial for maintaining safety and operational efficiency, especially in situations where changes in wind conditions could otherwise interfere with the chimney's ability to vent properly. Proper chimney height is a key factor in ensuring that systems run effectively and safely, and adherence to these height requirements is vital in propane systems.
