accordingly.

Typical duct arrangement countertop series.

To maximize the ventilation performance of the vent

system:

1. Minimize the duct run length and number of

transitions and elbows.

2. Maintain a constant duct size.

3. Seal all joints with duct tape to prevent any leaks.

If needed, install any make up (replacement) air

system in accordance with local building code

requirements. Visit GEAppliances.com for available

makeup air solutions.

• Optional duct arrangement under concrete slab.

PVC duct should be used if installing under a poured

concrete slab.

• Install ductwork so the piece of duct nearest the

downdraft unit slots INTO the next piece of the duct.

Secure the joints with self-tapping screws and apply

duct tape around the joints to ensure an airtight seal.

6. BLOWER TO DUCTWORK ALIGNMENT

In general, the use of flexible ducting is discouraged

because it can cause severely restricted airflow.

However, if the blower outlet and the floor or wall

duct location do NOT align well, then flexible

METAL ducting can be used to adapt to an offset.

Good alignment without use of flexible ducting is best.
