Partial pieces may need to be placed on horizontal slides in the boat. Remove the cap from the end of the tube and place the boat just inside the opening. Use the quartz rod to carefully push the boat to the middle of the furnace tube. Put the cap back on the end of the tube. Do not force it.
Programming is done using three settings for each part of the program.
Controller boxes correspond to the furnace tubes in the same relative position. Holding the arrow keys will increase the speed with which numbers change. Both the up and down arrow keys can be used. Ramp rate is sign-independent. Direction will be automatically set by the difference between previous set temperature and current set temperature.
