Before converting an appliance to a different fuel type, what must be secured?

Before converting an appliance to a different fuel type, securing the code official's approval is crucial because it ensures that all modifications comply with local, state, and national codes, including safety and performance standards. The code official will verify that the conversion meets the applicable mechanical codes and regulations set forth to protect life and property, thus ensuring the safe operation of the appliance. This step also often involves reviewing plans, inspecting the installation, and ensuring that any specific requirements for the new fuel type are met.

While other elements, such as manufacturer's approval, insurance verification, and possibly a building permit, may be necessary in certain contexts, the essential requirement for compliance with mechanical codes specifically focuses on obtaining the approval from the code official to ensure safety and legal adherence.
