Location
A furnace of this type is typically installed in a calibration laboratory where
temperature conditions are generally well controlled. Best results will be ob-
tained from this type of environment. Avoid the presence of flammable materi-
als near the furnace. Allow 6 or more inches of air space around the furnace.
Adjust the levelers on the bottom of the furnace to level the furnace and to keep
it from rocking.

Power
The 9116A furnace power requirements are listed in Section 2.1 on page 7. The
furnace is supplied with a 14-gauge, 2-conductor plus ground cable and con-

may be removed at the furnace back panel and another used so long as it is
