On propane 2-psi residential systems, the system regulator must be installed within how many metres of the exterior wall if it is installed outdoors?

The correct answer is: 1

Propane 2-psi residential systems use a system regulator to control the pressure of the gas before it enters the house. According to safety regulations, this regulator must be installed within 1 metre of the exterior wall if it is located outside. This distance ensures that the regulator is easily accessible and visible for maintenance and emergency situations. As for the other options, they are incorrect because they are too far of a distance from the exterior wall for proper installation of the regulator. A distance of 2, 3, or 5 metres would make it difficult to inspect and service the regulator, increasing the potential for malfunction and safety hazards. Therefore, option A (1 metre) is the only suitable distance for proper installation of the system regulator.
