Final answer:
When converting from one form of energy to another, the installer must advise the user about the steps to eliminate the previous form, offer a warranty for the transition period, and inform them about alternative energy sources.
Step-by-step explanation:
When the installation of an appliance constitutes a conversion from another form of energy, such as oil to gas, the installer must:
- Advise the appliance user during installation about the steps needed to eliminate the previous form of energy.
- Offer a warranty covering the transition period from the old to the new energy source.
- Inform the user about alternative energy sources available for future use.
These steps are important in ensuring the safe and effective transition to the new energy source.
