NOTE
If furnace is to be used regularly, the airline regulator may be left open to 20 psi.
Exhaust tubing hook-up.
NOTE
Appropriate exhaust must be provided to remove smoke and gases produced in an ashing
procedure.
Using accessory stainless steel tubing available from Barnstead/Thermolyne Corporation (part
number AY408X1A) or equal quality 2.5 inch I.D. stainless steel tubing, connect flexible tubing
from vent port at top of furnace case to an appropriate negative pressure exhaust system. This
exhaust system must be capable of handling smoke and gases produced in an ashing procedure.

gases filling the work area. Without the connection, gases and smoke will escape around the
door seal and at the rear of the furnace.
