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 chamber.
•
Keep objects away from the thermocouple.
•
Use insulated tongs and mittens when load-
ing and unloading the furnace.
•
Always wear safety glasses.
•
Never come into contact with the heating ele-
ments. Hitting the elements with tongs or lay-
ing the load against them will cause the ele-
ments to burn out prematurely.
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.
