Advance planning for chimney hoods—island
Recirculating installation
The ZV850/855 hood is designed to be vented to the outside,
but it can easily be converted for recirculating operation.
Recirculating kits are included for the ZV850/855 hood. These
kits include charcoal filters, a support frame with air deflector
and a vented decorative duct cover
to complete the installation. Kits are
sized for ceiling height.
The ZV925SLSS is designed for either
vented or recirculating operation. All
necessary parts are included.
The ZV1050 is not convertible to
recirculating operation.

This vent hood must use 6" round duct.
• Plan the shortest and straightest route for venting exhaust
to the outdoors.
• Use metal ductwork only.
• For satisfactory performance, duct run should not exceed
100 feet equivalent length for any duct configuration. Refer
to the duct fittings chart in the installation instructions.
• Install a wall cap or roof cap with damper at the exterior
opening. Order the wall or roof cap and any transition
needed in advance.

Stainless steel island hoods
Chimney vent hoods are available in 42" and 36" widths.
• Duct cover accessories to meet ceiling heights are required
for the ZV850 island hood. One accessory must be ordered
with the vent hood.
• The ZV925, ZV850 and ZV855 vent hoods are supplied with a
two-piece decorative duct cover to reach an 8' to 9' ceiling.
An optional duct cover accessory is available for 9'1" to 10'1"
ceiling heights.
• The ZV1050 hood is supplied with a duct cover for an 8'
ceiling height (7'11" to 8'1"). Optional duct cover accessories
are available for 9' and 10' ceiling heights.
• The installation height must be determined in advance for
island chimney hood models.
• All duct cover accessories must be ordered with the vent
hood and be on-site at the time of installation.
• Review the following chart to determine the appropriate
accessory duct cover.
Required duct cover accessories for vented installations
Structural support
These vent hoods are heavy. Adequate structural support
must be provided. Hoods must be secured to cross-framing
positioned between ceiling joists.
• The vent hood and duct cover(s) must be on-site before final
framing and wall finishing. This will help to accurately locate
the ductwork and electrical service.
• Final installation will be much easier if the hood is installed
before the range or cooktop below.
• Mounting templates are provided with the installation
instructions to help accurately position the hood on the
ceiling above the cooking surface.
Electrical requirements
These vent hoods must be supplied with 120V, 60Hz, and
connected to an individual, properly grounded branch circuit
protected by a 15- or 20-amp circuit breaker or time-delay fuse.
• The junction box is located on top of the hood. Route the
wiring as close to the installation as possible through the
ceiling. Refer to the installation instructions for details.
