Installation Instructions

• P

ro-Flex

SST can be routed beneath, through and along side floor and ceiling joists. Consideration

must be given to future construction possibilities. Alternate locations could include between supply and

eturn air ducts which also provides protection.

•

Pro-Flex

can be routed inside hollow wall cavities. This is the preferred for vertical sections of piping

rather than horizontal sections. Avoiding horizontal runs through the walls will minimize the need for

striker protection.

• Pro-Flex

can be routed on top of ceiling joists. This is the preferred method of routing in areas where

slab-on-grade construction is prevalent.

•

Pro-Flex

has passed the ANSI/AGA LC- 1, which include testing for suitability for exposure of CSST

piping systems to outdoor environments.

a) OUTDOORS:

Pro-Flex

when installed outdoors, the external yellow jacketing

shall remain intact as much as possible for the given

installation. Any portions of the exposed stainless steel tubing

shall be wrapped with tape or sleeved to prevent later threats by

acids or chloride as cleaning solutions for masonry.

(Note: Self bonding silicone tape is recommended here for its durability.)

b) BURIED or EMBEDDED: Pro-Flex

CSST shall NOT be buried directly in the ground or

directly embedded in concrete (patio slabs, foundations or

walkways) When necessary, to bury or embed CSST, the tubing

shall be routed inside a non-metallic, watertight conduit that has

an inside diameter at least 1/2 inch larger than the O.D. size of

the CSST tubing. The ends of the conduit installed outdoors,

must be sealed at any exposed end to prevent water from

entering. NOTE: No mechanical joint fittings are permitted in the

conduit. (See page: 30)

c) ALONG SIDE A STRUCTURE:

Pro-Flex

when installed along the outside of a structure

(between the ground and a height of 6 ft) in an exposed

condition, the CSST tubing shall be protected from mechanical

damage inside a conduit or chase. A conduit or chase is not

required if the tubing is installed in a location that will not

subject the CSST to mechanical damage.
