Running 40 feet of ward flex

[xchainsz]

What's up guys. I was wondering would you run ward flex outside rather than black iron mainly because of the cost difference? And is it safe?

It is approved to be ran outside, just make sure that it is properly supported as per code requirements. And please don't strip the jacket too far back, just need the first 4 corrugations exposed for the connector (if its yellow). If you're using black ward flex, no more than 5 corrugations exposed.

4.3.6 OUTDOOR INSTALLATIONS

Per CSA/ANSI LC-1 CSA 6.26 WARDFlex® CSST products are approved for installation where exposure to outdoor environments can occur. The following guidelines shall be followed when installing WARDFlex® outdoors to protect tubing and fittings from the effects of weather.

A. The covering shall remain intact as much as practical for the given installation. Any portion of exposed stainless steel shall be wrapped with tape (e.g. PVC, Self Fusing Silicone) or sleeved (e.g. PVC, Polyolefin) to prevent corrosive attack by acid wash or other caustic compounds that may be present. If contact with caustic compounds should occur ensure that all traces are immediately removed to prevent premature corrosion failure.

B. WARDFlex® mechanical joint fittings shall be protected from the effects of weather when used outdoors. After the connection is made to outdoor equipment the fitting assembly shall be wrapped with tape (e.g. PVC, Self Fusing Silicone) or by applying shrink sleeves (e.g. PVC, Polyolefin) around the entire assembly.

C. When installed outdoors between grade and six feet above WARDFlex® must be protected inside non-metallic conduit or installed in a location where it will not be subjected to mechanical damage.

D. When installed in crawl spaces or underneath mobile homes, WARDFlex® shall be installed in accordance with these installation instructions.
