Gas Flex Line Outside home?!?

[Greg Subick]

I have not seen this done before and need to know if it is improper to install outdoors from a fuel supply line and then up about 40 feet into an attic to supply natural gas for a furnace. While I see this all the time on the interior of a home, I have never seen it outside!?! If it is allowed for exterior use, is there an acceptable length that can be used?

These are the markings I got off the pipe itself:

Gaz Combustible 125G (EHD25) R18545

Sorry, the markings were actually the following:

Gaz Combustible 125G (EHD25) R18545

CSST has to be bonded http://www.csstsafety.com/Images/CSST-Direct-Bonding-Tech-Bulletin.pdf

...and can't be in close proximity to metal building components, ie: ductwork, water pipes, gutters...

The short answer is Yes, CSST can be run outdoors. There are some installation defects though-- read the manufacturer's installation instructions..........

I believe you have gathered incomplete marking data and transcribed it incorrectly from some OLDER "TracPipe (R)", which may or may not have been approved for the US Market ("GaZ Combustible" is the FRENCH marking - "FGP", "Fuel Gas" or "Fuel Gas Pipe" is the U.S. Market required marking). The file number "R18545" is what has lead me to this identification."125G" I believe to be incomplete as well. I would have expected 125GER. There should have been a space between "EHD" and "25". "EHD" is the Equivalent Hydraulic Diameter". I expect you are looking at 3/4" (20 mm) Old TRAC PIPE, pre-2004, and NOT "COUNTER-STRIKE".The fittings should be identification marked as well.This should NOT be installed as it is pictured.

H.G. you are correct all the way around. Sometimes I can't read my own writing. I have done additional research on this and yes, installation is incorrect throughout the exterior and interior. Lots of work to be done on this one!;)

Definitely recommend reading the CSST manual John posted. It's the easiest way to figure out the requirements.
As far as I remember outdoor installation is Ok if done properly. I haven't read the manual for a while but from what I remember, I think there was something about the line being defective if the yellow jacket is gone and the tube is exposed. I could be wrong so read the manual.
Very weird installation, I'm not sure that's something an actual contractor would do.

Thanks for everyone's replies as well as the links that were sent. Very informative and actually, the manuals are quite clear on the installation. As for this house....one word....MESS!
