properly install and maintain this equipment
could result in an explosion and/or re
causing property damage and personal
injury or death.
Fisher™ electric pilot heater 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 electric pilot heater vents gas or 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.

Product Description
The electric pilot heater Type RPE is used for reheating gas
supplying pressure reducing regulator pilots to avoid the
inconveniences caused by freezing which occurs during
large pressure drops and/or low ambient temperatures.
A “regulator bottom” version exists.
The Type RPE consists of :
• An explosion-proof junction box
• A thermometer pocket containing the heating element and
a probe
INTRODUCTION

.
Note: the electrical terminals 4 and 6 of the thermostat
(key 2) must be shunted to cut off supply in the case of
rupture of the thermal probe (key 5).
Note: the electrical terminals 2 and 3 of the Type RPE
connector block (key 4) must be shunted so that the heating
elements (key 6) are connected in series.
Note: the thermostat (key 2) and the power relay (key 3)
must be protected by 2A fuses (protection against
short-circuit of the heating elements).
Note: the thermostat (key 2) and the power relay (key 3) are
assembled on a symmetrical DIN rail.
Regulator bottom electrical heater
The Type RPE is assembled on the regulator bottom with 4
xing screws M8 x 20.
The Type RPE can be installed in an explosive risk zone.
The thermostat and power relay must be installed in an
non-explosive risk zone.
Pneumatic Connections
The Type RPE is to be installed between the pilot lter and
the pre-expansion relay.

WARNING
!
Personal injury or equipment damage, due
to bursting of pressure-containing part may
result if this device is overpressured or is
installed where 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 the installation is in
compliance with all applicable codes
and regulations.
Additionally, physical damage to the device
can cause personal injury and property
damage due to bursting of pressure
containing parts.
To avoid such injury and damage, a possible
approach could be e.g. install the device in a
safe location.
All interventions on the equipment should
only be performed by qualied and
trained personnel.
COMMISSIONING
WARNING
!
All interventions on the equipment should
only be performed by qualied and
trained personnel.
Preliminary Verications
Thermostat start-up positions
• Temperature range selector (A) - 0/30 °C
• Adjustment of the temperature setting (B) - 30
• Differential selector (C) - 2
Position before commissioning
• Pilot feeding valve
Closed
Commissioning
• Pilot feeding valve
Open slowly
The equipment is commissioned.
The thermometer pocket’s axis is to be
installed vertically.
A support must be used to avoid pressure
force on the regulator’s body.
No modication should be made to the
structure of the equipment (drilling, grinding,
soldering...).
Verify that the inlet side is protected by an
appropriate device(s) to avoid exceeding the
limits of utilization (PS,TS).
Verify that the limits of utilization correspond
to the appropriate operation conditions.
The equipment should not receive any type
of shock.
Fire, seismic and lightning are not taken into
consideration in standard regulators.
If required, a special product selection
and/or specic calculations may be supplied
according to specic requirement.
MAINTENANCE
WARNING
!
To avoid personal injury or property damage
from sudden release of pressure, isolate
the electric pilot heater Type RPE from the
pressure system and release all pressure
from the main valve before performing
maintenance operations.
Servicing Check
Recommended frequency
• Once a year minimum.
Verication
• Probe, heating cartridges.
Replacement
The user should verify or carry out a
protection adapted to the environment.
4
• In case of visible wear and/or tear in these parts,
replace them.
Type RPE
Precautions Before Disassembly
• Close the pilot feeding valve.
• Bleed of the pressure from the heater tube.
• Switch off the power supply.
Disassembly
• Unscrew the junction box’s cover (key 10).
• Unscrew the M3 screw (key 9) and carefully take out the
screw (key 9), the nut (key 8), the washer (key 7) and the
O-ring (key 6).
• Pull out the heating cartridges (key 5) and the probe
(key 4) and check for wear and/or tear.
SPARE PARTS
WARNING
!
If the Type RPE electric pilot heater was on
before this operation, heating cartridges may
be hot. If it is the case, wait until cool off
before doing the maintenance operation.
• If a replacement is needed, unscrew the screw from the
terminal block related to the element to change, take off
the element and put a new one in the same terminals.
Reassembly
• Perform above operations in reverse order.
• Lightly lubricate heating cartridges before putting them
back in the thermometer pocket.

DECLARATION OF CONFORMITY
We declare that the electrical heaters, Type RPE, are aimed to put on the market for usage in explosive atmospheres and that they
apply to the following:
- articles of the directive 2014/34/UE
- norms: • EN 60079-0: 2012
• EN 60079-1: 2014

11 Description
Electric heater type RPE 180 985.
- The heater is to:
- Maintain a minimum temperature in the body of a regulator in ‘ zero flow’ to assist start up.
- Maintain a minimum temperature in the control circuit of a press ure regulator.
- Options:
- Electric pilot heater (with heating pot).
- Regulator bottom electric heater (without heating pot).
The temperature regulation is carried out through a relay, by a pro be HAGER type EK083 and
through a multi-range thermostat HAGER type EK 186 set to max imum 60°C (or equival
The thermowell of the RPE is constantly bathing in the non-flam mable gas. Around the RPE, an
explosive atmosphere may occur, when:
- Opening of a valve,
- Opening of a vent,
- Leakage at a sealed connection.
If the sensor is switched off, the heating elements are switched off.
The RPE can operate in the absence of gas circulation.
The thermowell is be mounted vertically.
Rating: 230 VAC – 280 W- 50/60 Hz
The heater is fitted with a ¾ NPT flameproof cable gland.
