COMBAT® CTCU UNIT HEATERS INSTALLATION OPERATION AND SERVICE MANUAL

16.5 Flue Fan Vertical Installation (Models 22 - 32)

1. To remove the fan, remove 5 screws securing the fan/ mounting plate to the vent box.

2. To remove the fan from the mounting plate, remove the 2 screws.

3. Refit in reverse order.

4. To change the flue and air intake orientation from back to top, remove the fan/mounting plate as explained in Steps 1 and 2.

5. Rotate the motor 90º counter- clockwise and reinstall the 3 screws.

6. Remove intake and exhaust cover(s) from top of the heater.

7. Rotate the fan, mounting plate and gasket clockwise until the flue adapter lines up with the top hole. Secure with 5 screws.

8. Discard the piece of duct.

9. Install the intake/exhaust cover and install the 3" alum-mylar flex duct (after bending it to a tight radius by hand).

10.Install intake and exhaust cover(s) over the holes on the back of the heater.

11. Ensure sealed joints. Ensure mounting plate orifice is clear and not obstructed.
