!
Personal injury or equipment damage,
due to bursting of pressure-containing
parts may result if this regulator is
overpressured or is installed where
service conditions could exceed the limits
given in the Specification section and
on the appropriate nameplate, or where
conditions exceed any rating of the
adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices to prevent service conditions
from exceeding those limits. Also, be sure
the installation is in compliance with all
applicable codes and regulations.
Additionally, physical damage to the
regulator could break the pilot off the
main valve, causing personal injury and

property damage due to bursting of
pressure-containing parts. To avoid such
injury and damage, install the regulator in
a safe location.
All Installations
A Type EZL regulator bleeds no gas to atmosphere
during normal operation, thus making the regulator
suitable for installation in pits and other enclosed
locations without elaborate venting systems. This
regulator also can be installed in pits subject to flooding
by venting the pilot spring case above the expected
flood level so that the pilot setting can be referenced to
atmospheric pressure.
1. Only personnel qualified through training and
experience should install, operate, and maintain a
regulator. Before installation, make sure that there
is no damage to, or debris in the regulator. Also,
make sure that all tubing and piping are clean
and unobstructed.
