Vent Sensor Assembly (continued)
Note: Vent Sensor MUST be aligned as shown in fig. 5-4.4 so that Vent Sensor wire
lays in the proper channel of the Heat Exchanger.
Install Vent Sensor onto the Heat Exchanger ensuring that the three (3) screw holes line up and the Vent Sensor
wire is located on the proper side of the Heat Exchanger.
Note: Heat Shield must be located on inside face of Vent Sensor.
Using a #2 cross-tip screwdriver, secure the Vent Sensor to the Heat Exchanger with three (3) screws.
Place the Vent Sensor wire into the channel on the side of the Heat Exchanger ensuring that there is no strain on
the connections at the Vent Sensor end. Lightly re-crimp channel to secure Vent Sensor wire. Be careful not to
damage the wire during this procedure.
Using a 5/16" socket or nut driver, secure the Vent Sensor connector (J5) clip to the Burner Housing with a hex
head bolt. Note: this bolt also secures the Burner Housing to the Heat Exchanger.
Connect the Vent Sensor connector (J5) to the Logic Wiring Harness. Ensure the locking tab is engaged.
