Description

This version of the ESP is the correct part for any model made after 2008. This updated ESP has red wires, as opposed to the previous probes which could have had black, yellow, or white wires. New Circuit boards are now sensing the condition of the differential pressure switch. (FIG 4) 

Notes for ordering replacement parts:

  • If you need a new probe: Order to match your existing probe. Red= #3-20-00844
  • Black, White, or Yellow Probe: Order the black Probe.
  • If you need a new board: Order using the part numbers included here.
  • If installing on a unit with an old probe = Dipswitch #5 “OFF”.
  • With new probe= Dipswitch #5 “ON”.
  • The DVC500 uses two probes, ESP and TCP(temperature control probe). They must be of the same color

    Instructions

    Install Instructions For Heatilator Eco Choice Red Thermister Exhaust Sensing Probe (ESP): 3-20-00844-AMP

    You must be careful not to bend an ESP probe if removing it for maintenance purposes. Bending the sheath of the probe will usually ruin the sensor. Likewise, when cleaning your stove, care should be taken to not bend the sensor when cleaning. Do not send brushes or vacuum tools through the stove blindly. Before cleaning your stove for the first time, find the ESP probe and make sure that it is not going to be in the way when cleaning. If it is, remove it from its mount prior to performing work.


    Using a 1/4" socket, remove the mounting screw and remove the thermocouple from the stove. Trace the wires back to the control board and unplug the wires.
