If the regulator vents gas or a leak
develops in the system, service to the unit
may be required. Failure to correct trouble
could result in a hazardous condition.
Installation, operation and maintenance
procedures performed by unqualifi ed
personnel may result in improper
adjustment and unsafe operation. Either

Introduction
Scope of the Manual
This manual describes and provides instructions
and parts list for Type 1098-EGR or 1098H-EGR
regulator complete with a standard P590 Series
fi lter and either a 6350 Series regulator, a 61 Series
pilot or a Type Y600AM pilot. The Type 1806 check
Types 1098-EGR and 1098H-EGR
W6956
valve is also covered when a 61 Series pilot is used.
Instructions and parts lists for monitoring pilots and
other equipment used with this regulator are found in
separate manuals.
Description
Types 1098-EGR and 1098H-EGR regulators provide
economical and accurate pressure control in a
wide variety of applications: natural gas distribution
systems; fuel gas supply to industrial boilers, furnaces,
ovens and mixers; and large commercial/industrial
establishments such as shopping centers and schools.
They are also used in plant air service and in liquid
service where a slow stroking time (approximately
30 to 90 seconds) is desired on both opening and
closing the main valve.
