Furnace Loading - Barnstead 30400 Operation Manual

Note
Failure to connect the exhaust port to
an appropriate exhaust system will re-
sult in smoke and gases filling the
work area. Without the connection,
gases and smoke will escape around
the door seal and at the rear of the
furnace.
Caution
Do not overload your furnace cham-
ber. If the load is to be heated uniform-
ly it should not occupy more than two-
thirds of the furnace chamber. Failure
to observe this caution could result in
damage to furnace components.

Furnace Loading

• For best results, use only the center two-thirds
of the furnace chamber.
• Use Hearth plate to elevate load when placing
on bottom heating element. This prevents bot-
tom heating element from overheating and burn-
ing out. (Part Numbers PHX1 & PHX2)
• If you are heating a number of small parts,
spread them throughout the center of the fur-
nace chamber.
• Keep objects away from thermocouple.
• Use insulated tongs and mittens when loading
and unloading furnace.
• Always wear safety glasses.
