DEC RATIVE H DS

Acustom decorative hood can be created out of wood,

plaster, tile or metal. The shape of the decorative hood is

not critical as long as the hood liner fits completely inside

the hood. The decorative hood and liner must fit together

at the bottom edge in both width and depth. The height of

the hood does not have to match the height of the liner.

Interior dimensions of the decorative hood must exceed

exterior dimensions of the liner. Refer to pages 6–7 for

dimensions of the hood liner.

The lower 3/4"(19) of the 4" (102) reveal is stainless steel

and the rest of the reveal is aluminum. Make sure the

bottom edge of the liner does not extend more than 3/4"

(19) below the decorative hood for a finished look.

BL WER ASSEMBLIES

Wolf pro ventilation hood liners are shipped without the

blower assembly. Internal, in-line and remote blowers are

available through your authorized Wolf dealer. For local

dealer information, visit the find a showroom section of

our website, wolfappliance.com.

The blower will vary in size and is dictated by the cooking

surface, the volume of air that needs to be moved and the

length of the duct run. Refer to ventilation recommenda-

tions in the Wolf design guide.

IMP RTANT N TE: Use only a Wolf blower with the pro

hood liner.

Electrical Requirements

Wolf pro ventilation hood liners require a separate,

grounded 120 V AC, 60 Hz power supply. The service

should have its own 15 amp circuit breaker. Locate the

electrical supply within the shaded area shown in the

installation illustration on the previous page.

IMP RTANT N TE: You must follow all National Electrical

Code regulations. In addition, be aware of local codes and

ordinances when installing your service.

Install Ductwork

IMP RTANT N TE: Pro ventilation hood liners must

exhaust to the outdoors.

Wolf recommends that the ventilation hood be installed

30" (762) to 36" (914) above the countertop. Consult a qual-

ified HVAC engineer for specific ducting applications.

A 10" (254) round duct is recommended for pro ventilation

hood liners. Use only rigid metal ductwork, do not use flex

ducting.

Decide where the ductwork will run between the hood liner

and the outside. Pro hood liners have a vertical discharge.

A straight, short duct run will allow the ventilation hood to

perform most efficiently. Limit the number of elbows and

transitions. The duct run should be no longer than 50'

(15 m). There is a possibility of noise issues, if a remote

blower is used with a short duct run.

Unless you are using a remote blower, a roof or wall cap

must be installed. Connect 10" (254) round metal ductwork

to the cap and work back towards the hood. Use duct

sealing tape to seal joints between ductwork sections.

Pro hood liners have a backdraft damper included in the

transition assembly. Local codes may require the use of an

additional backdraft damper. Contact your local HVAC

professional for specific requirements. In cold weather

installations, a backdraft damper is necessary to minimize

the backflow of cold air into the room.

Local building codes may require the use of make-up air.

Consult your local HVAC professional for specific require-

ments in your area.

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

Wall Framing

1)Layout dimensions of the back of the hood liner on the

wall. Dimensions will vary with the width of the hood

liner. Refer to the illustration and chart on page 7.

2) Using minimum 2" (51) x 4" (102) lumber, construct the

wall framing flush with the wall studs and centered in

the location that the hood liner will be mounted. Proper

structural support is required to accommodate the

weight of the hood liner.

3) Refer to the illustrations below for the location of

mounting holes for pro hood liners and a cross-section

view of a typical installation.

Framing must be fastened together and to ceiling joists

to provide enough structural strength to support the

weight of the hood and internal blower, if applicable.

Hood Liner Preparation

IMP RTANT N TE: For pro ventilation hood liners using

an internal blower, refer to installation instructions

provided with the blower assembly.

1) Remove the filters of the hood liner by pushing each

filter up at the angle it is placed in, then rotate the

bottom of the filter down. Refer to the illustration

below. Remove the center filter first. Gloves should be

worn when handling filters.

2) The hood liner is shipped with the transition attached

upside down in the top of the hood liner. It must be

removed and reinstalled in the proper position. Remove

the blower mounting plate from the hood liner by

removing four nuts from inside the liner. Detach the

transition by removing four shipping screws. Reinstall

the blower mounting plate back onto the liner and

reattach the transition onto the top of the blower

mounting plate. Refer to the illustration on page 11.

3) Attach the transition to existing ductwork with sheet

metal screws and duct sealing tape.

4) If you are installing an in-line or remote blower, drill a

7/8"(22) hole through the wood framing for the conduit.

Refer to in-line and remote blowers on pages 12–13.
