Excessive Flow Valve (EFV):

A valve designed to automatically close or activate when the flow rate of fuel exceeds the valves prescribed flow rate.

Significant Definitions

10

Flashback Arrestor Check Valve :

A device designed to prevent the backflow passage of one gas into the supply system of another gas also preventing the passage of flame into the gas supply system.

Third-Party Agency/Certified/Tested :

The code has now defined who, how and what the material and products are to go through in order to be determined approved and in compliance with this code.

12/2/2014

11

Combustible Material / Assembly

The code has specifically identified combustible material as anything that is not noncombustible. Floors , walls , ceilings having one or

more components in it not defined as noncombustible (Combustible Assembly)

Noncombustible Material:

The code has defined noncombustible material with 3 specific parameters that are required to be met during testing to deem the material noncombustible.

G2415.2 & 404.2 CSST

Lets review some important points aboutCSST.


42


G2415.2 & 404.2 CSST

It is to be bonded as per 2012 IRC G2411.1.1

For exterior installation, the ends of exposed CSST are to be protected.

Special case hardened nail plates are to be used where applicable when subject to damage.

It is to be installed in a water tight, and properly vented sleeve when installed underground.
