Installation
Install the regulator using a straight run of pipe the
same size or larger as the regulator body. Flow
through the regulator body is indicated by the ow 
arrow on the body. If a block valve is required, install a
full ow valve between the regulator and the blanketed 
vessel. For proper operation at low setpoint ranges,
the regulators should be installed with the spring case
pointed down.
