Proper ductwork installation will al-

low ventilator to efficiently move air from

hood to outside the building. Use smooth

galvanized ductwork with a minimum num-

ber of elbows and bends. All joints must be

sealed and run upstream. Ceiling ductwork

should "stub down", cut to length, to mate

with backdraft damper of installed liner (see

illustration).

Ductwork is not provided with hood.

NOTE: It is recommended to have the

range hood on site before determining the

terminal position of the duct 'stub'. Before

measuring, attach backdraft damper to ex-

haust outlet.

NOTES

1. In cold climates, insulate the ductwork

in cold spaces to prevent moisture con-

densation in the winter, which can run

down the ductwork, into the hood be-

low. A thermal break may be required.

2. No screening material on the wall cap

or roof jack. Screens cut airflow by

20%- 50% and should not be used. If a

rodent, or small animal barrier is re-

quired, screen openings should be 1" x

1" minimum.

3. The opening on the wall cap or roof

jack should be wide enough and deep

enough to accept the proper sized duct

and allow the air to flow continuously

and freely. Wall caps and roof jacks

should have a solid, gravity damper

that opens and closes freely with the air

flow.
