DESCRIPTION

 

The 13004 continuous probe conditioning box is designed for use with a continuous furnace. Although many such furnaces are equipped with programmable controls that could conduct probe conditioning on a regular basis, it has been our experience that this programming capability is seldom used.  Existing burnoff systems that are designed to work with a programmable controller cannot be used as "stand alone" systems without significant modification. Further, most cannot provide adequate air for burnoff because they simply switch the output of low flow reference air pumps to the burnoff fitting without regard to adequate flow. The 13004 is also provided with a delay timer to allow the probe signal to return to normal before control is re-established.  Fig. 1 shows the piping and wiring diagram of the 13004.
