SELECTING A VENTILATION SYSTEM

Selecting a Ventilation System

DUCTING CONSIDERATIONS

IMPORTANT NOTE:

Unless used in a recirculating applica-

tion, Wolf ventilation hoods and downdrafts must be vented

to the outside. Use only rigid metal ducting.

Typically, wall-mounted ventilation hoods can be vertical

or horizontal discharge, while wall chimney hoods, island

hoods and hood liners are vertical discharge only. For

some wall hoods, an accessory horizontal discharge kit is

required. In a horizontal discharge application, additional

framework may be needed to accommodate the remote

blower. Wolf downdraft systems have an adjustable dis-

charge that will allow you to negotiate ducting around oor

joists and other obstacles.

Depending on the specic installation, ducting can run

through the roof, external wall or eave. A remote blower can

not be ducted through an eave.

A straight, short duct run with a limited number of elbows

and transitions will allow the hood or downdraft to perform

most efciently. Wolf ventilation hoods will operate most

efciently when the duct run does not exceed 50' (15 m)

in length, 40' (12 m) for downdrafts. To calculate total duct

length, refer to page 10.

ELECTRICAL REQUIREMENTS

All Wolf ventilation products require a separate, grounded

electrical supply. Installation must comply with all applicable

electrical codes.

A ground fault circuit interrupter (GFCI) is not recommended

and may cause interruption of operation.
