Copper propane line thru exterior wall

[Jon mackay]

Is this wall transition allowed or does a protective sleeve need to be in place here?

JM:

Most of the protection provisions apply to passage through plates, studs, and solid walls. If that is metal siding, an argument could be made for a protective sleeve.

Copper.org: Applications: Fuel Gas - Installing Copper Fuel Gas Systems (http://www.copper.org/applications/fuelgas/rg-installing.html)

G2415.5 (404.5) Protection against physical damage. In concealed locations, where piping other than black or galvanized steel is installed through holes or notches in wood studs, joists, rafters or similar members less than 1.5 inches (38 mm) from the nearest edge of the member, the pipe shall be protected by shield plates. Shield plates shall be a minimum of 1/16-inch-thick (1.6 mm) steel, shall cover the area of the pipe where the member is notched or bored and shall extend a minimum of 4 inches (102 mm) above sole plates, below top plates
and to each side of a stud, joist or rafter.

IFGC 404.7 All piping installed outdoors shall be elevated not less than 3.5 inches above ground.> piping installed above ground, outdoors, and installed across the surface of roofs shall be securely supported and located where it will be protected from physical damage. Where passing through an outside wall, the piping shall also be protected against corrosion by coating or wrapping with an inert material. Where piping is encased in a protective pipe sleeve the annular space between the piping and the sleeve shall be sealed.

David, this section that you quote is in reference to installations above roofs.

[David Bell]

No, it is for any above ground piping, and roofs.
