Pro Wall Hood Installation 10

Install Ductwork

10" (254) round, rigid metal duct is recommended for pro

ventilation hoods.

A straight, short run is most effective and will ensure

proper operation. For best results, duct run should not

exceed 50'

(15 m). For runs exceeding 50' (15 m), a higher

CFM blower may be required to maintain proper air flow

and performance. A remote blower installed on a short

duct run may increase the potential for noise.

Internal and in-line blowers require a roof or wall cap (not

provided). Connect ductwork to the cap and work back

towards the ventilation hood. Use sheet metal screws and

aluminum tape or high temperature duct tape to seal joints

between ductwork sections.

To reduce the risk of fire, use only metal ductwork.

ll pro ventilation hoods include a backdraft damper in the

transition assembly. Local codes may require the use of an

additional backdraft and/or make-up air damper. Contact

your local HVAC professional for specific requirements.

Backdraft and make-up air dampers are available through

your authorized Wolf dealer. For local dealer information,
