Single Residential & Commercial Metering

Utilities supplying natural gas and propane use Firebag® thermal shutoffs to protect residential and commercial dwellings with a level of fire safety previously not available. By installing a FireBag thermal activated shutoff, prior to the gas meter, these utilities protect the safety and property of their customers and first responders in the event of a fire.

FireBag Thermal Activated Shutoffs are available in multiple piping configurations and sizes to accommodate the varying piping requirements of a natural gas or propane system. A recommended FireBag piping orientation and design illustration is highlighted as follows or simply contact your local Firebag distributor for additional information and specifications:

High-pressure Applications

Gas regulators are highly vulnerable in fire conditions. When
exposed to extreme heat, they can fail and release gas under high pressure, intensifying the fire.
To prevent this, it is critical to shut off the gas supply prior to the regulator. For systems with
high-pressure gas supply requiring a regulator, it is recommended to install a FireBag upstream of
the gas regulator in one of the following options:

A. Optional Locations

• Inlet of the shutoff valve (FxM)
• Outlet of the shutoff valve (MxF)
• Inlet of the gas regulator (FxM)
