Wolf cooktop wall ventilation hoods are available in the classic stainless steel finish. Cooktop wall hoods are sold as a shell only, internal, in-line and remote blower options are available.
P owerful multi-speed blowers draw odors and smoke into the five-layer mesh filter. Filters remove easily for cleaning. The sculpted classic stainless steel shape not only provides the power you expect from Wolf, but also the beauty you have come to appreciate as well.
This wall mount cooktop hood is 36" (914) wide by 21" (533) deep. It has a telescopic chimney flue that allows you to reach a ceiling height of 8' (2.4 m) to 9' (2.7 m) with a finished look. A flue extension to accommodate 10' (3 m) ceilings is available as a sales accessory.
Wolf cooktop wall hoods are recommended for use with Wolf electric and gas cooktops and integrated modules. For Wolf dual fuel ranges, gas ranges, sealed burner rangetops and gas rangetops, a Pro ventilation hood should be used.

Model CTWH36 Cooktop Wall Hood
I N S T A L L A T I O N N O T E S
Refer to the illustrations and specifications for overall dimensions and installation specifics.
Wolf cooktop wall hoods are recommended for use with Wolf electric and gas cooktops and integrated modules. The hood should be at least as wide as the cooking surface.
IMPORTANT NOTE: Wolf Pro ventilation hoods should be used with Wolf dual fuel ranges, gas ranges, sealed burner rangetops and gas rangetops.
Wolf cooktop wall hoods come with a telescopic chimney flue that allows you to reach a ceiling height of 8' (2.4 m) to 9' (2.7 m) with a finished look. A flue extension to accommodate
10' (3 m) ceilings is available as a sales accessory.
Installation of the cooktop wall hood should be 24" (610) to 30" (762) from the bottom of the hood to the countertop. Follow the dimensions shown in the Installation illustration.
IMPORTANT NOTE: 8' (2.4 m) ceilings will not allow for a 30" (762) maximum height above the countertop. Based on a 36" (914) high countertop, an 8' (2.4 m) ceiling will allow for a maximum height above the countertop of
27 5 / 16 " (694).
Wolf cooktop wall hoods are shipped without a blower assembly. Internal, in-line and remote blower assemblies are available. Blower options also vary with the volume of air that needs to be moved and the length of the duct run. Refer to the charts at the end of this section for ventilation recommendations and blower options.
IMPORTANT NOTE: Install this ventilation hood only with a Wolf blower.
Wolf cooktop wall hoods require a separate, grounded 110/120 V AC, 60 Hz power supply.
The service should have its own 15 amp circuit breaker. Placement of the outlet is not critical, as long as you provide a minimum of 12" (305) of 120 V AC, 60 Hz power cable. Locate electrical within the shaded area shown in the
Installation illustration.
You must follow all National Electrical Code regulations. In addition, be aware of local codes and ordinances when installing your service.
Wolf cooktop wall hoods have an 8" (203) round vertical discharge.
Refer to the installation instructions shipped with each Wolf product for detailed specifications. This information can also be found on our website, wolfappliance.com.

Wolf cooktop wall ventilation hoods come with a telescopic chimney flue that allows you to reach a ceiling height of 8' (2.4 m) to 9' (2.7 m) with a finished look. A flue extension to accommodate 10' (3 m) ceilings is available as a sales accessory.
Installation of the wall hood should be 24" (610) to 30" (762) from the bottom of the hood to the countertop.
IMPORTANT NOTE: 8' (2.4 m) ceilings will not allow for a 30"
(762) maximum height above the countertop. Based on a 36"
(914) high countertop, an 8' (2.4 m) ceiling will allow for a maximum height above the countertop of 27 5 /
16
" (694).
IMPORTANT NOTE: Both sections of the telescopic chimney flue must be installed in order for the chimney to be lifted for service.
To determine placement of the cooktop wall hood, you must calculate the height of the telescopic chimney flue. Refer to the illustration and chart below.
To calculate the height of the telescopic chimney flue:
1) First measure A (total kitchen height from finished floor to finished ceiling height).
2) Next measure B (height from finished floor to countertop).
3) Then determine the minimum C value (distance from countertop to bottom of hood). Refer to the chart for ceiling heights from 8' (2.4 m) to 9' (2.7 m). Dimension C must be greater than 24" (610) and less than 30" (762).
4) To determine the upper flue section height: E=A-(C+B+D) .
IMPORTANT NOTE: If dimension E falls between 0" (0) and
1 /
2
" (13), you will need to modify the flue to affix to the flue attachment brackets. For ease of installation, Wolf recommends that dimension E be no less than 1 /
2

Wolf Ventilation Recommendations
W O L F B L O W E R A S S E M B L I E S
A ventilation system must include a blower assembly. With a few exceptions where internal blowers are included, Wolf ventilation hoods and downdrafts are shipped without the blower assembly. An internal, in-line or remote blower assembly must be selected to accommodate the cooking appliance, CFM requirements and homeowner preferences. Internal, in-line and remote blower assemblies are available as sales accessories through your Wolf dealer.
Wolf internal, in-line and remote blowers are for use with Wolf cooktop hoods, downdraft systems and Pro ventilation hoods and hood liners.
IMPORTANT NOTE: Use only a Wolf blower with all Wolf ventilation products.
Internal blowers are mounted inside the hood canopy or downdraft blower box. In-line blowers are mounted in between the hood and the exterior of the home. Remote blowers can be mounted on the roof or in some cases, on an exterior wall. Refer to the illustrations below for dimensions of Wolf in-line and remote blowers.
Ventilation recommendation charts on the following pages provide minimum CFM recommendations according to the cooking appliance and ventilation system used and blower options for each specific ventilation hood or downdraft.
