What are three requirements for gas equipment installed in a residential garage?

The correct choice highlights the important requirements for gas equipment installed in a residential garage, which are designed to ensure safety and compliance with building codes. Equipment must be installed at least 18 inches above the finished floor level to avoid potential damage from vehicles. This height requirement is crucial in preventing leaks and ensuring that any potential ignition source is shielded from ground-level hazards.

Additionally, gas equipment must be protected from vehicles, which typically means using barriers or placing the equipment in a location where it cannot be struck by cars or equipment. This protection is essential for maintaining the integrity of the gas system and reducing the risk of accidents.

Finally, using listed equipment is important because listed equipment has been tested and certified to meet specific safety standards. These standards ensure that the equipment functions safely and effectively in residential settings. Choosing unlisted equipment could lead to safety issues, as those products may not have undergone the same rigorous testing. Thus, the combination of these three requirements ensures compliance with safety codes and reduces the likelihood of accidents in a residential garage setting.
