Please note the following WARNINGS:
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
preexisting 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 Barnstead|Thermolyne
Corporation at 1-800-553-0039.

Intended Use
The FB1300 Model and FB1400 Model furnaces are general purpose laboratory and heat
treating furnaces. For optimum element life,
observe the following temperature ranges:
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 three
straight hours, and intermittent use is operating
the furnace for less than three hours.
The unit consists of a heating chamber and a
digital controller. See Figure 1 for the overall
shape and general features of the unit.
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 a ceramic fiber insulation. The
temperature is controlled by an electronic control which provides one temperature setting.
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 unit which also houses the electrical
connections.

O
PERATION
Page 14
13
• For best results of furnace loading, use
less than two-thirds of any dimension of
the chamber. Maintain a 3/4" clearance
between the load and the sides of the
chamber.
• If you are heating a number of small
parts, spread them throughout the middle two thirds of the chamber.
• Keep objects away from thermocouple.
• Raise your load up off the furnace floor
with small pieces of ceramic or a hearth
plate to promote even heating.
• Use insulated tongs and mittens when
loading and unloading furnace.
• Always wear safety glasses.
Furnace Loading
Caution
Do not overload your furnace
chamber or allow the load to
touch the thermocouple. If the
load is to be heated uniformly, it
should not occupy more than
two-thirds of any dimension of
the chamber. Failure to observe
these cautions could result in
damage to furnace components
and/or load.
Page 15
14
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).
The resistance wire is high-grade nickel-chromium.
Some chemicals, notably sulphur, halogens, and
cyanides, attack this wire at high temperatures, so
avoid spilling these chemicals in the furnace or
heating them any hotter than necessary. The
refractory cement helps to protect the wire, but will
not completely immunize it from damage.
All heating elements must be considered expendable, and replacement is expected; however, reasonable care in their use will greatly extend the service they will give. As the manufacturer has no control over the use or care of the elements, no specific service guarantee can be made.
Housekeeping is vital to your electric furnace—
KEEP IT CLEAN! Run your furnace up to 871°C
(1600°F) empty occasionally to burn off the contamination that may exist on the insulation and elements. Run for approximately two hours with the
door slightly open.
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 (500°F).
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 controller readings.
Clean by wiping the outside case of the unit with a
damp cloth and mild soap solution.
Preventive Maintenance
Warning
Before using any cleaning or
decontamination method
except those recommended
by Barnstead|Thermolyne,
users should check with
Barnstead|Thermolyne that
the proposed method will not
damage the equipment.

6. Remove the back insulation block by
opening the door and gently pushing it
out. Support this insulation block while
removing it, as it is quite soft and easily
crumbled at the edges.
7. Remove bottom cover to obtain access
to terminals.
These steps will expose the heating element
leads and insulating bushings in the bottom
plate of the furnace.
8. Cut the element leads between the element and the terminal block. (There are
two leads.) The element and hearth
plate unit may now be removed by
pushing it straight back out of the furnace. Use care not to damage the
chamber insulation when removing the
hearth plate and element as it can be
reused if it has not been contaminated.
9. Remove the old element lead wire and
power wires from the terminal block,
and save the glass sleeving for reinstallation on the new element leads.
Sleeving must be replaced if cracked or
brittle!
10. New elements are shipped flat to protect them from damage in shipment,
and to save space in storage. They
must be formed before installation.
11. Place the element on a flat surface with
the smooth (exposed element) side up.
Place a board or other straight edge
along one row of notches.
12. Gently bend the element along the
straight edge. The refractory cement
will break along the row of notches.
MAINTENANCE AND SERVICING
Note
The hearth plate contains no
heating coil, and may be saved
for re-installation if it is in good
condition. The hearth plate is
replaceable independent of the
heating element.
Page 19
18
Make the bend 90°, avoiding excessive bending. (The element wires will
be exposed at the corner thus formed.
This will not affect its life or performance.)
13. Bend the other side of the element.
14. Place the hearth plate across the open
end of the ‘’U” shaped element.
15. Slide the element and hearth plate unit
into the chamber, pushing it firmly
against the hearth collar. Use care not
to damage the soft insulation. Remove
any crumbs of insulation that may get
between the unit and the hearth collar.
16. Thread the element leads through the
ceramic bushings. Bend the leads so
they lie close to the refractory plate
and the bottom insulation block. (The
easiest and safest way to do this is to
press the wire flat with a stick or blunt
pusher. Do not use a sharp object or
nick the wire.)
17. Replace the glass sleeving and bend
the lead 3/4 turn around the terminal
screw. Cut off the excess wire.
Replace power wires on top of element lead wires and tighten screw. Do
not cross the wire over itself around
the terminal; this makes it difficult to
keep the connection tight and prevents
good electrical contact. If you have
excess wire, cut it off. Make sure element lead wires are not touching any
other wires.
18. Replace bottom cover of control unit.
