FireBag Fire Shut Off Valve

Con Edison will be requiring the installation of the TECO FireBag fire shut-off valve for all new MP/HP customer services effective 11/08/2021. The FireBag will be installed between the HOSV and residential/commercial regulators (1”, 1-1/4”, 2”). If a building fire occurs at the HOS, the FireBag fire shut-off valve is designed to shut-off gas to building at ~212 degF preventing gas from feeding the building fire reducing the risks and hazards to emergency response personnel. The FireBag was rigorously tested by the Con Edison R&D Department, Gas Engineering, Fire Alliance , and independently tested by GTI.  
 
Attached is copy of TECO FireBag manufacturer information and installation guidelines.  This information goes over design, installation, and operation of the FireBag.
