Flexible gas piping OK for exterior?

[bwooddell]

Does anyone know if CSST - the corrugated stainless steel flexible gas line - approved for exterior installation? Thank you in advance!

No code gurus around to help Bryan?

Since I know I have stalkers, I'll post here to see if we can get Bryan some help. Hold on, Bryan. They'll be here shortly, I think.

Thanks Russel - much appreciated. Also appreciate reading all your posts...

What exactly do you mean by exterior installation?.....I know it cannot be buried or touch the ground, but other than being used from Black Iron to say a Barbecue which is fine (appliance connector) I wouldn't know what you mean by exterior.

I used to install this piping and went to all the certification classes for it when I was a fireplace installer. It cannot be buried. Other than that, you can put it anywhere (with proper strapping). It can run along the bottom of the entire house, out the soffits wherever.

Thanks, Shane.

Maybe that was done in a workwoman-like manner. Uh-oh.

Remove the baffle from the dryer vent, also.

Hi Linda...I may be to late for help but I am certain it is not allowed to go thru walls.
Do not know the exact code off hand but would bet I am right.

Piping

Customer owned piping shall be designed and installed in
accordance with the NFGC.

Corrugated Stainless Steel Tubing

Corrugated Stainless Steel Tubing (CSST) is allowed for new
construction, remodeling, and retrofitting applications in residential
and light commercial structures. CSST shall meet the design and
installation requirements set forth in ANSI/AGA LC 1-1993.
CSST is not designed to be used as a flexible gas appliance
connector and shall not be used as a substitute. The use of CSST
as a final connection for permanently installed appliances, such
as water heaters, furnaces, and boilers is allowed. CSST shall
terminate outside of the appliance jacket where the excessive
heat may ignite or damage the protective coating. The use of
CSST as a final connection of movable gas appliances, such as
ranges and clothes dryers, is not allowed.
CSST shall not be installed outdoors and shall not be run
underground unless installed in a sleeve or conduit.

Am I wrong, or did I see somewhere that there was a class action lawsuit concerning CSST?

[Michael R. Boyett]

There have been reports of fires caused by lightning strikes near homes with CSST flexible gas piping. The root cause of these fires has been attributed to either a lack of or inadequate bonding of the CSST which has resulted in arcing damage to the tubing. This problem resulted in a class action law suit involving four CSST manufacturers: Omegaflex (TRACPIPE or COUNTERSTRIKE); Parker-Hannifin Corp. (PARFLEX); Titeflex Corp. (GASTITE); and Wward Manufacturing, Inc. (WARDFLEX). The parties to the suit have signed a Settlement Agreement that provides class members with a partial to full financial reimbursement for either a lightning protection system or upgraded bonding of their existing CSST system. For further information on the Settlement Agreement, visit www.CSSTsettlement.com; call the Administrator at 1-800-420-2916; or write to the CSST Settlement Administrator at P.O. Box 4349, Portland, OR 97208-4349.

CSST is permitted to go through walls unless prohibited by a local ordnance. Don't confuse the appliance connector photo in post #7 with the original question re: CSST. There's a good CSST .pdf installation guide that has been posted before; I'll see if I can locate it.

Yep...here it is, everything you want to know re: CSST: http://www.divshare.com/download/1466610-efc . This is a 3MB, 105 page pdf so it may take some time to load.

Thanks to everyone for their replies/assistance. The GasTite document was very informative and provides the answers I was interested in, at least from the manufacturer specifications. Looks like I will need to check on local requirements as well, since it appears that Chicago does not allow for some of the installation practices approved by the manufacturer (based on the post by Robert Elliott). I am beginning to wonder about this whole concept of being a "generalist" in the home inspection business

My pleasure. My wise ol' grandmother said, "Learn how to get people to respond." I have.
