Multi-Meter Gas Manifold Metering Applications

Natural gas and propane utilities now are able to add thermal shutoff protection to multi-meter installations at residential and commercial buildings, adding a level of fire safety previously unattainable. In addition to installing a FireBag upstream of the gas regulator, various FireBag configurations are available for the multi-meter gas manifolds downstream of the regulator, where each residence or business has its own gas meter. The FireBag configuration and sizes are available to utilities to meet the following installation options.

A. In line with the Manifold
FireBag thermal shutoffs can be installed “prior-to” or “coupled-with” a multi-meter
manifold to provide protection to multiple meters using just one device. Sizes include
1¼”, 1½” and 2″ in Female x Female configurations.

B. In line with the Manifold Nipples to the Meter
Individual Firebag installations place the thermal activated shutoff fittings between the
manifold nipple and inlet to the meter bar. Sizes include 1″, 1¼” and 1½” NPT Female x Male configurations.

C. In line with the Meter Swivels & Nuts (As shown under Low-Pressure Applications)
In line with the meter swivels & nuts using a FireBag Meter Connection Kit, which can easily be installed on a new or existing meter installation. The FireBag Meter Connection Kit utilizes a FireBag fitting accompanied by a BLANK companion fitting.
