Generated explanation

The cross-sectional drawing traces an underground gas service line to an exterior meter and through the foundation wall into the building. A building line connects to a manifold serving branch lines and risers. One branch rises through the floor to a stove, with a shut off valve and flexible connector at the appliance. Another branch runs across the basement and down a drop line to a boiler, with a shut off valve and a capped sediment trap or drip leg below the appliance connection. The illustration identifies gas piping terminology without highlighting a defect.
