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

Introduction
Intended Use
The type 21100 furnaces are small, inexpensive furnaces
ideally suited for school, chemical and industrial laboratories. They are intended for applications requiring temperatures up to 1100°C for manual control bases or temperatures up to 1200°C for the electronic single set point
control bases. See specification sheet for continuous and
intermittent operating temperatures.
General Usage
Do not use this product for anything other than its intended usage.
Principles of Operation
The furnace chamber is heated by heating elements embedded in a refractory material. The tubular chamber is
insulated with a ceramic fiber insulation. The furnace
chamber is supported by the control base which also
houses the electrical connections. Two types of controls
are used:
1. Manual Control - A percentage input control which
compensates for line voltage fluctuation and ambient
temperature changes. The temperature is measured by a
thermocouple and is displayed on a pyrometer.
2. Single Set Point Control - An electronic control which
enables the user to bring the furnace up to a pre-set temperature and hold the temperature.

Use insulated tongs and mittens when loading and un-
loading furnace.
Always wear safety glasses.
Use the proper process tube.
Furnace Loading
Caution
Do not overload your furnace chamber.
Failure to observe this caution could
result in damage to furnace components.
20
Preventative Maintenance
Contamination is a major cause of element failure, therefore, when possible, remove the fume forming material
before heating. (e.g., cleaning cutting oil from tool steel).
Housekeeping is vital to your electric furnace—KEEP IT
CLEAN! Run your furnace up to 871°C empty occasionally to burn off the contamination that may exist on the
insulation and elements. Run for approximately two
hours with the process tube removed.
Element life is reduced somewhat by repeated heating
and cooling. If the furnace is to be used again within a
few hours, it is best to keep it at the operating temperature or at a reduced level such as 260°C.
During normal use the thermocouple in your furnace can
become oxidized and cause inaccurate readings; therefore, we suggest that if you regularly use your furnace
you should change your thermocouple once every
six months to assure the accuracy of your meter
readings.
General Cleaning Instructions
Wipe exterior surfaces with lightly dampened cloth containing mild soap solution.
Preventative Maintenance
Warning
To avoid electrical shock, this furnace
must always be disconnect from the
power supply prior to maintenance and
servicing.

Troubleshooting
WARNING
THIS FURNACE CONTAINS REFRACTORY CERAMIC INSULATION WHICH CAN PRODUCE RESPIRABLE FIBERS AND DUST WHEN HANDLED. THESE FIBERS CAN CAUSE IRRITATION AND CAN AGGRAVATE PRE-EXISTING RESPIRATORY DISEASE. THE INTERNATIONAL AGENCY FOR RESEARCH ON
CANCER (IARC) HAS CLASSIFIED REFRACTORY CERAMIC FIBER AS POSSIBLY CARCINOGENIC.
AFTER SERVICE REFRACTORY CERAMIC FIBER DUST MAY CONTAIN CRYSTALLINE SILICA, WHICH
MAY CAUSE LUNG DAMAGE (SILICOSIS) AND WHICH HAS BEEN CLASSED BY IARC AS APROBABLE
CARCINOGEN.
The refractory ceramic materials are located in the hearth collar and in the chamber of the furnace. Tests performed by the manufacturer indicate that there is no significant risk of exposure to dust or respirable refractory ceramic fiber resulting from operation of the equipment under normal conditions. However, there may be a
risk of exposure to respirable refractory ceramic dust or fiber when repairing or maintaining the insulating materials, or when otherwise disturbing the materials in a manner which causes release of dust or fibers therefrom. Through the use of proper handling procedures you can work safely with these insulating materials and
minimize any exposure. Accordingly, before you repair or replace any insulating materials, or perform any other servicing on this product which could disturb or cause exposure to dust from insulating materials, you
should consult the appropriate Material Safety Data Sheets (MSDS’s) for such products with respect to proper
handling and appropriate protective equipment. For additional MSDS’s, or additional information concerning
the handling of refractory ceramic products, please contact the Customer Service Department of Barnstead
