Which code governs the installation of propane supply systems in mobile homes?

The installation of propane supply systems in mobile homes is governed by the CSA Z240.4.1 Code. This code specifically addresses the unique requirements and safety measures needed for mobile homes, which are distinct from other gas installations due to their construction, mobility, and the potential environmental factors they face.

The CSA Z240.4.1 Code outlines the standards for the design, installation, and maintenance of propane systems specifically for mobile homes, ensuring that they adhere to safety regulations and are suitable for the specific conditions that mobile homes may encounter.

In contrast, while the National Fuel Gas Code and CSA-B149.1 Code govern broader gas installation requirements, they do not specifically target the intricacies of propane systems in mobile homes. The Ontario Building Code pertains to general building requirements but does not specifically address propane installations in mobile homes. Therefore, those options do not align precisely with the specialized needs for propane supply systems in mobile homes, making CSA Z240.4.1 the correct choice for this context.
