UIDELINES FOR INSTALLATION OF PRO-FLEX

(

CSST) FLEXIBLE GAS PIPING IN OUTDOOR

APPLICATIONS

PRO-FLEX

tubing and fittings meet all performance requirements for outdoor applications and comply with

NSI/AGA-LC1 standards.

n outdoor applications, the external yellow jacketing on

RO-FLEX

hould not be removed. All exposed tubing on

the outside of a structure or located between the ground and a 6 ft height must be protected in a sealed conduit or

eather-tight chase which is routed and secured to avoid mechanical damage.

When buried underground or encased in cement (slabs, foundations, etc.) the tubing must be routed within a plastic

watertight conduit. This nonmetallic conduit is to have an inside diameter 1/2 inch larger than the

PRO-FLEX

tubes

outer diameter. Exposed conduit ends must be sealed to prevent entry of water and debris. Local code authority will

always take precedence. Therefore make sure you check with your local building authority or code authority having

jurisdiction.

Gas Meter Connections:

Gas meters are generally supported by the building structure or by framework brackets independent of the structure.

Do not use

PRO-FLEX

CSST as a direct connection to any meter which must be supported by the piping. On

structure supported meters, accepted practice is to connect the meter outlet to a termination flange mounted on the

exterior wall or to penetrate the exterior wall with a steel pipe and provide a rigid attachment for the meter and

PRO-FLEX

tubing within the building.
