Fisher
regulators must be installed,
®
operated, and maintained in accordance
with federal, state, and local codes, rules
and regulations, and Emerson Process
Management Regulator Technologies,
Inc., instructions.
For LP-Gas service, an approved
regulator (such as one listed by U.L.)
should be used. The installation,
in most states, must comply with
NFPA standards.
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.
Call a gas service person to service
the unit. Only a qualified person must
install or service the regulator.

Introduction
Scope of the Manual
This instruction manual provides instructions for
Installation, adjustment, maintenance, and parts
ordering information for Types S201, S201H, S201K,
S202, and S202H gas service regulators.
Description
S201 and S202 Series regulators are typically
installed on industrial and commercial applications.
The Types S202 and S202H regulators contain an
internal relief valve. Units with an "H" or "K" suffix
are similar to the basic regulators but deliver a higher
outlet pressure of 1 to 5 psig (69 mbar to 0,35 bar) and
2 to 10 psig (0,14 to 0,69 bar), respectively.
Specifications
The Specifications section lists the specifications for
the regulators. The following information is stamped
on the regulator at the factory: type number, date of
manufacture, spring range, orifice size, maximum inlet
pressure, maximum operating outlet pressure, and
outlet pressure which may damage regulator parts.
