Alert Signals
4Small Benchtop Muffle Thermo Scientific
Alert Signals
Warnings alert you to a possibility of personal injury.
Cautions alert you to a possibility of damage to the equipment.
Notes alert you to pertinent facts and conditions.
Hot surfaces alert you to a possibility of personal injury if you come in contact with a
surface during use or for a period of time after use.
Important Information
Your Thermo Scientific Thermolyne Type FB1300 Model or FB1400 Model Furnace has been
designed with function, reliability and safety in mind. It is your responsibility to install it in
conformance with local electrical codes. For safe operation, please pay attention to the alert signals
throughout the manual.
This manual contains important operating and safety information.
You must carefully read and understand the contents of this manual prior to the use of this furnace. 
If the equipment is used in a manner not specified by the manufacturer, protection provided by the
equipment may be impaired.
Warnings
To avoid electrical shock, this furnace must:
1. Use a properly grounded electrical outlet of correct voltage and current handling capacity.
2. Be disconnected from the power supply prior to maintenance and servicing.
3. Have the door switch operating properly.
To avoid burns, this furnace must:
Caution: Hot Surface - Avoid Contact. To avoid burns, do not touch the exterior or interior surfaces of
this furnace during use or for a period of time after use.
To avoid personal injury:
1. Do not use in the presence of flammable or combustible materials; fire or explosion may result.
This device contains components which may ignite such material.

Warning
Thermo Scientific Small Benchtop Muffle 5
2. Refer servicing to qualified personnel.
3. Always wear safety glasses or a safety shield and high temperature gloves when loading or
unloading the furnace. Long sleeved, fire retardant clothing and a fire retardant apron is also
recommended.
Warning
This warning is presented for compliance with California Proposition 65 and other regulatory agencies
and only applies to the insulation in this product. This product contains refractory ceramic, refractory
ceramic fiber or fiberglass insulation, which can produce respirable dust or fibers during disassembly.
Dust or fibers can cause irritation and can aggravate pre-existing respiratory diseases. Refractory
ceramic and refractory ceramic fibers (after reaching 1000°C) contain crystalline silica, which can cause
lung damage (silicosis). The International Agency for Research on Cancer (IARC) has classified
refractory ceramic fiber and fiberglass as possibly carcinogenic (Group 2B), and crystalline silica as
carcinogenic to humans (Group 1).
The insulating materials can be located in the door, the hearth collar, in the chamber of the product or
under the hot plate top. Tests performed by the manufacturer indicate that there is no risk of exposure
to dust or respirable fibers resulting from operation of this product under normal conditions. However,
there may be a risk of exposure to respirable dust or fibers when repairing or maintaining the insulating
materials, or when otherwise disturbing them in a manner which causes release of dust or fibers. By
using proper handling procedures and protective equipment you can work safely with these insulating
materials and minimize any exposure. Refer to the appropriate Material Safety Data Sheets (MSDS) for
information regarding proper handling and recommended protective equipment. For additional
MSDS copies, or additional information concerning the handling of refractory ceramic products,
please contact the Customer Service Department at 1-800-438-4851.

2 Introduction
Intended Use
8Small Benchtop Muffle Thermo Scientific
Intended Use
The Type FB1300 Model and FB1400 furnaces are general purpose laboratory and heat treating
furnaces. For optimum element life, we recommend observing these temperature ranges: from 100°C
(212°F) to 982°C (1800°F) for continuous use, or from 982°C (1800°F) to 1100°C (2012°F) for
intermittent use. Continuous use is operating the furnace for more than 3 hours and intermittent use is
operating the furnace for less than 3 hours.
The unit consists of a heating chamber and a digital controller.
General Usage
Do not use this product for anything other than its intended usage.
Principles of Operation
The furnace chamber is heated by a single three section resistant heater which is embedded in a
refractory material. The chamber is insulated with ceramic fiber insulation. The temperature is
controlled by an electronic control. The temperature is measured by a thermocouple and is registered
on a digital display. For safety, door switches are incorporated to remove power from the heating
elements when the door is opened. The furnace is supported by the control section which also houses
the electrical connections.

Be sure ambient temperature does not exceed 40°C (104°F). The recommended
ambient temperature is 17°C - 27°C. Ambient above this level may result in damage
to the controller.
Allow at least six inches of space between the furnace, at least 40 inches above the
furnace and any combustible surface. This permits the heat from the furnace case to
escape so as not to create a possible fire hazard.
To avoid electrical shock, this furnace must always use a properly grounded outlet of
correct voltage and current handling capacity.

Site Selection
14 Small Benchtop Muffle Thermo Scientific
Site Selection
Install furnace on a sturdy surface and allow space for ventilation.
Electrical Connections
1. The electrical ratings are located on the specification plate on the back of the furnace. Consult
customer service if your electrical service is different than those listed on the specification plate. Be
sure the front power switch is in the OFF position before connecting the furnace to your electrical
supply.
FB1300 and FB1400 Models
Electrical Conditions for operating the furnaces in the EU:
The furnaces are intended for use at a network supply with a maximum system impedance of Zmaxat
the point of connection, according to EN 61000-3-11 clause 6.2.2. The user has to ensure that the
device is operated on a network supply that meets these requirements. If necessary, the system
impedance can be confirmed by the energy supplier.
The system impedance at the point of connection is typically less than 0.2 Ohm.

To avoid personal injury do not use in the presence of flammable or combustible
chemicals; fire or explosion may result. This device contains components which may
ignite such materials.
Caution: Avoid Contact. To avoid burns, this furnace must not be touched on the
exterior or interior surfaces during use or for a period of time after use.
Always wear safety glasses or a safety shield and high temperature gloves when
loading or unloading the furnace. Long sleeved, fire retardant clothing and a fire
retardant apron is also recommended.
To avoid electrical shock, the door safety switch must be operating properly.
6 Operation, All Models
Power Switch
16 Small Benchtop Muffle Thermo Scientific
Power Switch
Both the ON/OFF power switch and the digital display will illuminate when power is switched ON.
The furnace will begin to heat to its controller's current setpoint. (See the instructions for your type of
controller for information on checking and setting the setpoint.)
Cycle Light shown on the display
The cycle light will illuminate whenever the power is being applied to the heating elements. The cycle
light will turn on and off as the furnace reaches the setpoint.
Door Safety Switch
The door safety switch removes power from the heating elements when the door is opened. Open and
close the door a few times; Note an acoustic click of the switch during opening and closing of the door.
If this condition is not true, consult the Troubleshooting section before proceeding. This check must
be done when the furnace is heating and the cycle light on the display is illuminated.

Eurotherm 3216 Controller Operation
The single setpoint model w/OTP furnace controller is a single setpoint controller, which provides a
single digital display to indicate the current chamber temperature or setpoint temperature.
This temperature controller features sensor break protection, self-tuning capability and over
temperature protection (OTP) with an additional OTP relay device.
Basic Operation
When the controller is turned ON it will perform a short self-test and then display a default page. The
measured value (process value) is found in the upper display and the setpoint is found in the lower
display.
