Installing the Reznor CD2 Downturn Nozzle Kit involves several steps to ensure safe and effective operation. Here's a general guide. Always consult the specific installation manual provided with your kit for detailed instructions and safety information.

1. Assemble the Downturn Nozzle: Begin by assembling the top and side panels of the downturn nozzle assembly. Use the screws included in the kit to secure the right and left panels to the top panel. Make sure the panel with slotted holes is on the door side of the unit.
2. Option CD3 or CD5 Assembly: If you're installing the CD3 or CD5 option, assemble the second nozzle section now; it will be joined later.
3. Safety First: Before you begin any work, turn OFF both the gas and electrical power supply to the unit heater. Allow sufficient time for the louvers to cool down before proceeding.
4. Remove the Access Door: Loosen the screw lock, open the access door, disconnect the door strap, and remove the door completely.
5. Remove the Face Plate: Remove the face plate assembly by taking out the screws located near the access door slots, the horizontal louvers, and those securing the face plate to the unit.
6. Position the Vertical Louver Frame: For CD4 or CD5 installations, position the vertical louver frame and secure it to the face plate using the provided screws.
7. Connect Nozzle Sections (CD3 or CD5): If you are installing options CD3 or CD5, position the second assembled nozzle section in the outlet of the nozzle already installed. Then, use the screws from the kit to secure the sections together.
8. Attach the Downturn Nozzle to the Face Plate: Mount the downturn nozzle assembly to the face plate by securing the top and side panels to the back of the face plate. Then, slide the nozzle bottom into place and secure the side panels to the face plate.
9. Install the Assembly on the Unit: Align and secure the nozzle and face plate assembly to the front of the unit. Make sure to secure the nozzle blockoff and blockoff panel, re-installing the original screws.
10. Adjust the Louvers: Follow the instructions in the manual to install and adjust the louvers to achieve the desired air throw pattern.
11. Restore Power and Test: Turn the gas and electrical power back ON. Light the heater according to the lighting instructions in the manual. Finally, check that the unit is operating correctly.

Remember to refer to your Reznor CD2 Downturn Nozzle Kit installation manual for all specific details and safety precautions. This ensures a proper and safe installation.
