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.
