temperatures from 400°F (204°C) to 1600°F (871°C) for

continuous use, or temperatures from 1600°F (871°C) to

1832°F (1000°C) for intermittent use.  Continuous use is

operating the furnace for more than 3 hours and intermit-

tent use is operating the furnace for less than 3 hours.

General Usage

Do not use this product for anything other than its intend-

ed usage.

Principles of Operation

The furnace chamber incorporates a heating element that

is embedded into the side walls and top and back of heat-

ing chamber.  The ceramic fiber oval muffle with four

heating surfaces creates even heat distribution within the

chamber.  The temperature is controlled by a micropro-

cessor control with a type K Chromel/Alumel Thermocou-

ple.  A fan is provided in the furnace to provide forced air

cooling for the temperature controller.  A door safety

switch removes power to the heating elements whenever

the furnace door is opened.
