1.2  LIMITATIONS OF THE GUIDELINES 
is document is intended to aid the professional gas installer in the design, installation and testing of fuel gas piping 
systems using corrugated stainless steel tubing (CSST) for residential housing, commercial and industrial buildings. 
It would be impossible for this guideline to anticipate and cover every possible variation in building configurations, 
construction styles, appliance loads and code restrictions. erefore, there will be applications that will not be covered by 
this guideline. For applications that go beyond the scope of this guideline, the installer should exercise sound engineering 
principles and practices and/or contact Gastite for engineering assistance. 
e techniques outlined within this guideline are recommended practice for generic applications. ese practices must be 
reviewed for compliance with all applicable local fuel gas and building codes. In the event that there is a conflict between 
this guide and local code, the more stringent requirement will take precedence. 
Using components from other flexible gas piping systems other than those specified as part of the FlashShield™ system 
is prohibited and may result in poor system performance and serious bodily injury or property damage. Additional 
information pertaining to gas piping systems is available from your local gas utility or propane supplier. Please visit the 
Gastite web site at www.gastite.com for additional updates and technical bulletins.

printing, Gastite cannot guarantee that the local administrative authority will accept the most recent version of these 
codes. It is the ultimate responsibility of the installer to determine suitability and acceptance of any building component 
including gas piping. Gastite assumes no responsibility for labor or material for installations made without prior 
determination of local code authority acceptance.
