Final answer:
The appropriate code for a mobile home with a propane supply that's been made into a permanent home is the CSA-B149.1 Code for Natural Gas and Propane Installation Code, which prescribes safe installation practices.
Step-by-step explanation:
The code that applies to a mobile home with a propane supply that has been converted to a permanent home site is CSA-B149.1 Code for Natural Gas and Propane Installation Code. While the CSA-Z240 Series Code for Manufactured Homes deals with the structure of mobile homes, and the CSA-B149.2 Code for Propane Storage and Handling is concerned with the propane storage aspect, CSA-B149.1 specifically pertains to the installation of propane systems, making it the correct code for this context. The CSA-C22.1 Canadian Electrical Code would be relevant for the electrical installations within the home but does not directly deal with the propane supply. Applying the correct code ensures that the propane system is installed and operated safely, following national standards, which is crucial especially when propane is utilized in remote locations due to the absence of natural gas infrastructure.
