Personal injury, equipment damage or
leakage due to escaping accumulated
gas or 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 Specifications section and on the
appropriate nameplate or where conditions
exceed any ratings 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.
Additionally, physical damage to the
regulator may result in personal injury
and property damage due to escaping
accumulated gas. To avoid such injury
and damage, install the regulator in a
safe location.
Standard Single-Pilot Regulator
(Figure 3)
Installations
A Type 1098-EGR or Type 1098H-EGR regulator
bleeds no gas to the atmosphere, making it suitable for
installation in pits or other enclosed locations without
elaborate venting systems. This regulator can also be
installed in pits subject to flooding by venting the pilot
spring case above the expected flood level so that the
pilot diaphragm is exposed to atmospheric pressure.
