Gas PipingQuestion 257 of 360
When installing CSST, which document must be followed for support spacing, fittings, bonding, and physical protection?
a.Only the plumber's personal preference
b.Only the drain, waste, and vent code
c.Only the electrical code
d.The CSST manufacturer's listed installation instructions together with the adopted fuel gas code
Explanation
CSST is a proprietary listed system, so its manufacturer's installation instructions, along with the adopted fuel gas code, govern support spacing, approved fittings, bonding, and required physical protection such as striker plates. Substituting generic methods can void the listing and create hazards. Keep the manufacturer instructions on site for the inspector.
