Furnace Loading - Barnstead 47900 Operation Manual

Furnace Loading

Caution
Do not overload your furnace chamber. If
the load is to be heated uniformly, it
should not occupy more than two-thirds
of the furnace chamber. Maintain at least
a 3/4" gap between the load and ele-
ments. Failure to observe this caution
could result in damage to the furnace
components.

Heating Elements
• For best results, use only the center
two-thirds of the furnace chamber.
• If you are heating a number of small
parts, spread them throughout the
center two-thirds of the furnace cham-
ber.
• Keep objects away from the thermo-
couple.
• Use insulated tongs and mittens when
loading and unloading the furnace.
• Always wear safety glasses.
• Never come into contact with the
heating elements. Hitting the ele-
ments with tongs or laying the load
against them will cause the elements
to burn out prematurely.
