How far should discharge from a regulator be from a building?

Explanation:
Discharge from a regulator must be kept away from a building so vented gas doesn’t accumulate near doors, windows, or air intakes. The safety standard is a minimum distance of three feet (about one meter). This keeps any vented propane gas dispersing in open air and away from openings or ignition sources, reducing the risk of gas entering the building or igniting nearby. Choosing a smaller distance than three feet would increase that risk, while a much larger distance, though safer, isn’t required by typical codes for residential propane systems. Therefore, three feet is the correct minimum distance.
