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.

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.
