Note: Vent Sensor MUST be aligned as shown in Figure 5.8-5 Vent Sensor

Assembly so that Vent Sensor wire lays in the proper channel of the Heat

Exchanger.

1.

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.

2.

Using a #2 cross-tip screwdriver, secure the Vent Sensor to the Heat Exchanger with

three (3) screws.

3.

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.

4.

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.

5.

Connect the Vent Sensor connector (J5) to the Wiring Harness. Ensure the locking tab is

engaged.
