What must an installer do when converting an appliance from another form of energy to gas?

When converting an appliance from another form of energy to gas, it is vital for the installer to advise the user in writing of the procedures necessary to discontinue the former energy supply. This ensures that the user is fully informed about the steps needed to safely and properly transition to a gas supply. Proper communication in written form helps create a clear record of the process, reduces the risk of misunderstandings, and emphasizes the importance of safety during the conversion process.

Providing a written advisory is crucial not only for the user's understanding but also for compliance with regulations that may govern the conversion process. It can include specific instructions on how to safely disconnect the previous energy source, which is critical to prevent potential hazards such as gas leaks or accidental ignition.

While informing users about legal requirements or verbally explaining the process may be useful, they do not provide the comprehensive clarity and accountability that written instructions afford. Simply installing the new gas supply without notification cannot ensure safety and could lead to non-compliance with established industry standards. Hence, the requirement for written documentation stands as a best practice in gas appliance installations and conversions.
