Emergency Reserve Header Installation
The Emergency reserve regulator, gauges, transducer,
pressure switch, and header inlet block, and pipe nipple
are included as a pre-assembled unit, loose within the
packaging.
The inlet for the Emergency Reserve bank is located
right above the right liquid bank. Install the pipe nipple
onto the inlet check valve, and then install the pre-
assembled regulator w/ gauges and sensors. If the
length of the provided pipe nipple is insufficient, install
a longer pipe to extend the assembly further away from
the manifold.
Install the Emergency Reserve Header (sold separately)
using the same method described for the left and right
bank header.
Vent Line Plumbing
The pressure relief valves are plumbed together
inside of the Manifold and are connected at a single
point on the top right of the manifold cabinet – the
connection is a ½” FNPT thread.
The vent line must be connected and plumbed by
the contractor in a manner compliant with the latest
version of NFPA 99.
Final Line Sensor & Gauge
Remove the plug in the Source valve and install the
final line sensor and gauge assembly (included).
The pressure switch is adjustable; the default settings
is 20% of the nominal delivery pressure of the gas per
NFPA99.
