When converting an appliance from another form of energy to gas, what must the installer do?

In the process of converting an appliance from another form of energy to gas, it is essential for the installer to remove all aspects of the previous installation. This step ensures that any remnants of the old energy source do not pose safety hazards or operational issues. For instance, components specific to the previous energy type, such as electrical systems, oil lines, or specific venting systems designed for solid or liquid fuels, could lead to malfunctions or unsafe conditions if not completely removed before the new gas installation takes place.

By completely removing these aspects, the installer guarantees that the new gas appliance will function correctly, operates safely, and adheres to relevant installation codes and regulations. This thoroughness is crucial for the reliability of the new installation and the safety of the end users. Therefore, completely removing all aspects of the previous installation is fundamental to a successful conversion to gas.
