STAND ALONE INSTALLATION – REAR VENT
***This installation only applied with the purchase of an optional 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.
