Electrical Connections

Insert the probe into the coupling at the base of the large box.  It is important that the probe is inserted at the correct depth to allow proper heating.  There should be between 10.0” and 10.5” between the bottom of the adjustable 1” NPT gland and the end of the probe (see sketch below).

 

 

Once the probe has been inserted into the heater, make the necessary electrical connections at the head of the probe.  Attach the green thermocouple wire from the electrical enclosure box to the thermocouple connection at the head of the probe (Positive (+) = Black; Negative (-) = Red).  The sensor wire should also be attached to the probe  (Positive (+) = Black; Negative (-) = White).

 

This unit has been pre-configured and tested prior to shipment.  To maximize the accuracy and longevity of the Heated Probe, it is recommended that the unit be operated at 1500°F.  It is also possible to configure the HP to match the temperature of your furnace.
