Excessive Flow Valve (EFV):
 A valve designed to automatically close
or activate when the flow rate of fuel
exceeds the valves prescribed flow rate.

12/2/2014
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.

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.


If the installation procedures are not know, than
codes states to follow the manufactures installation
instructions.

If the referenced standards and manufactures
installation instructions of a particular material do
not conform to the minimum provisions of this
code, than the code is to be followed and applied.

This section has been added and identifies CSST
piping specifically. CSST shall be installed per the
manufactures installation instructions, the
conditions of its listing and this code.
As in the past the most restrictive requirements
are to be followed. If the code has more
restrictive requirements than a manufacture’s
installation instructions the code overrules and is
to be followed. And vise versa.
