WARNING
▲
Failure to follow these instructions or
to properly install and maintain this
equipment could result in an explosion
and/or fire causing property damage and
personal injury or death.
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.
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 manual provides instructions for installation,
startup, adjustment and maintenance for Type 114PL
Pressure Reducing System. For pilots maintenance,
instructions and parts list, see Type BSL85 Instruction
Manual, D103711X012.
Product Description
Type 114PL
Type 114PL High-pressure Reducing and Low-flow
System is a battery of three Type BSL85 Pilots (see
Instruction Manual, D103711X012) where two of
them are pneumatically loaded and the third one
is spring-loaded. It is designed for high-pressure
reduction with low-flow conditions.
Type RPE (Electric Heater)
Type RPE can be used together with the Type 114PL.
Type RPE is used for reheating gas supplying
pressure reducing regulator pilots. Type RPE avoids
the inconveniences caused by freezing which
occur during large pressure drops. (See Instruction
Manual, D103694X012).

Principle of Operation
Type 114PL High-pressure Reducing and Low-flow
System uses inlet pressure as the operating medium,
which is reduced through the spring-loaded pilot to
load the pneumatic-loaded pilots’ cases.
When the outlet pressure (Pd) drops, the motorization
pressure (Pm) opens more the nozzles in the
pneumatic-loaded pilots supplying the required flow to
the downstream system.
Any excess motorization pressure on the actuator
diaphragm escapes downstream through the bleed
restriction in the pilot.
When the gas demand in the downstream system has
been satisfied, the outlet pressure (Pd) increases. In
this case, the outlet pressure closes the nozzles in the
pneumatic-loaded pilots until reach the setting value.

service conditions could exceed the
limits given in the characteristics
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 that installation is in compliance
with all applicable code and regulations.
Physical damage to the system can
break the pilot off the main valve,
causing personal injury and property
damage due to bursting of pressurecontaining parts. To avoid such injury
and damage, install the regulator in a

through training and experience should
install, operate and maintain a regulator.

Make sure that all tubing and piping are
clean and unobstructed.
The battery must be installed on
horizontal pipeline. Installation
according to EN 12186 is recommended.
When assembling with adjacent
elements take care not to create
pressure force on the body. The
assembling elements (bolts, O-rings
and flanges) should be compatible with
the geometry and working conditions of
the equipment.
Connect the impulse line keeping a
minimum distance of 4 x D to a straight
run of the outlet pipe.
No modification should be made
to the structure of the equipment
(drilling, grinding, soldering...). It is
recommended to install a servicing
valve on the outlet pipeline to facilitate
adjustments and bleeding off to
the atmosphere.

The equipment should not receive any
type of shock, especially the release
relay. The user should verify or carry out
a protection adapted to the environment.
The action of fire, seismic and lightening
are not taken into consideration in
standard regulators. If required, a
special product selection and/or specific
calculations may be supplied according
to specific requirements.
A regulator may vent some gas to
the atmosphere.
In hazardous or flammable gas service,
vented gas may accumulate, causing
personal injury, death or property
damage due to bursting of pressure
retaining parts.
Vent a regulator in hazardous gas
service to a remote, safe location
away from air intakes or any
hazardous location.
The vent line or stack opening must

General Installation
1. Install the regulator so that the flange connected
to the spring-loaded pilot’s feeding is in the
inlet side.
2. Use gaskets between pipeline and system flanges.
3. Connect the sensing line to the downstream.
Initial Verification
• PM unscrewed
• RM1 open
• RP1 open 3/4 turn
• R1, R2, R3, V1, V2 closed
Start up
1. Slowly open V1 (upstream valve).
2. Slowly open R1 and check the leakage of the pilot
nozzle PM by the absence of pressure rise on the
downstream pressure gauge.
3. Slowly open R2 and check the leakage of the
nozzle of the BPM1 by the absence of pressure
rise on the downstream pressure gauge.
Maintenance
Disassembly
Check the absence of pressure between inlet and
outlet valves.
Recommended Frequency
Every year:
• Disassemble the manometric boxes and nozzles.
• Control O-rings, diaphragms, grease.
Parts Ordering
When corresponding with your local Sales Office
about this regulator, include the type number and all
other pertinent information stamped on the nameplate.
Specify the 11-character part number when ordering
new parts. See Type BSL85 Instruction Manual,
D103711X012, for the parts list.
4. Slowly open R3 and check the leakage of the
BPM2 by the absence of pressure rise on the
downstream pressure gauge.
5. Adjust PM to the required value Pd (read on M1 if
necessary using valve P1).
