STAND ALONE INSTALLATION – REAR VENT 
***This installation only applied with the purchase of a duct cover (Model No. CH1120DC). 
Preparation before Installation 
NOTE:  TO AVOID DAMAGE TO YOUR HOOD, PREVENT DEBRIS FROM ENTERING THE 
VENT OPENING. 
-  Decide the location of the venting pipe from the hood to the outside. Refer to Figure 21. 
- A straight, short venting run will allow the hood to perform more efficiently. 
- Try to avoid as many transitions, elbows, and long run as possible. This may reduce 
the performance of the hood. 
- Use duct tape to seal the joints between pipe sections. 
- If necessary, prepare back wall frame with cross framing lumber for secure installation.  
Using references on Table 2 and measurements on page 21-22, decide the level of the 
lumber. Refer to Figure 22. 
Hood Preparation before Installation 
- Temporarily wire the hood to test for proper operation before installing. 
- Peel protective film off the hood and the duct cover (if any). 
- Remove the screws on the vent cover (rear) and cut along the line of the inner vent 
cover (rear) opening.  Refer to Figure 23. 
- Cut the vent cover (rear) opening and reverse to the other side. Refer to Figure 24.
