WARNING! TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK, OR INJURY TO PERSONS
OBSERVE THE FOLLOWING: a) Use this unit only in the manner intended by the
manufacturer. If you have any questions, please contact the manufacturer at
the address or telephone number listed in the warranty. b) Before servicing or
cleaning unit, switch power off at service panel, lock service panel, and lock
the service disconnection means to prevent power from being switched on
accidentally. When the service disconnecting means cannot be locked, securely
fasten a prominent warning device, such as a tag, to the service panel.
CAUTION: For general ventilating use only. Do not use to exhaust hazardous or
explosive materials and vapors.
WARNING! TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE: a) Never leave surface
units unattended at high settings. Boilovers cause smoking and greasy
spillovers that may ignite. Heat oils slowly on low or medium settings. b)
Always turn hood ON when cooking at high heat or when flambeing food (i. e.
Crepes Suzette, Cherries Jubilee, Peppercorn Beef Flambe’).

c) Clean ventilating fans frequently. Grease should not be allowed to
accumulate on fan or filter. d) Use proper pan size. Always use cookware
appropriate for the size of the surface element.
WARNING! TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE
GREASE FIRE, OBSERVING THE FOLLOWING:
a) Smother flames with a close-fitting lid, cookie sheet, or metal tray, then
turn off the burner. Be careful to prevent burns. If the flames do not go out
immediately, evacuate and call the fire department. b) Never pick up a flaming
pan — you may be burned. c) Do not use water, including wet dishcloths or
towels. A violent steam explosion will result. d) Use an extinguisher, only
if:
1. You know you have a Class ABC extinguisher and you already know how to
operate it. 2. The fire is small and contained in the area where it started.
3. The fire department is being called. 4. You can fight the fire with your
back to an exit.
RECOMMENDATIONS:
1.Consult a licensed ventilation contractor or qualified technician for proper
installation of exhaust ducting. Locate the cooking area for minimum cross
drafts-away from doors and windows, when possible.
2.Ducts must be of adequate size and duct runs should be as short as possible.
Where turns are necessary, keep turning radius as large and as smooth as
possible.
3.The ducting must be air tight. Use a minimum of 2 sheet metal screws at
every duct joint. Then, seal the duct joints with high quality duct tape.
4.Do not use this unit with any solid-state speed control device. 5.This unit
must be grounded.
INSTALLATION INSTRUCTIONS
WARNING! TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK, OR INJURY TO PERSONS
OBSERVE THE FOLLOWING:
a) Installation work and electrical wiring must be done by qualified person(s)
in accordance with all applicable codes and standards, including fire-rated
construction codes and standards. b) Sufficient air is needed for proper
combustion and exhausting of gasses through the flue (chimney) of fuel burning
equipment to prevent back drafting. Follow the heating equipment
manufacturer’s guidelines and safety standards such as those published by the
National Fire Protection Association (NFPA) and the American Society for
Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) and the local

PART 1: PLANNING THE INSTALLATION
TRADE-WIND® Designer Series Liners are designed for installation inside custom
hood canopies. Proper installation of the liner is directly related to the
material from which the custom canopy is constructed. A qualified person must
complete the installation of this unit. Because of the large size and weight
of this hood / liner, two installers are recommended. Plan the installation so
that all minimum clearances are met or exceeded. Dimensions shown provide
minimum clearances, unless otherwise specified.
Important: You must provide structural framing and tight backing in the areas
in which you are securing the liner inside your custom canopy. Failure to do
so could distort and damage the liner and void the warranty.
VENTILATION, DUCT SILENCERS, DAMPERS, AND DUCTING
TRADE-WIND® Duct Silencers are available from your local TRADE-WIND® dealer. When planning for installation using a duct silencer, please refer to the Installation Instructions provided with the duct silencer.
Given that most installations are different, a back-draft damper is not provided with this unit. TRADE-WIND® back draft dampers are also available from your local TRADE-WIND® dealer. Always install ventilation products with an approved wall or roof cap. Duct performance is improved by using round, smooth metal duct work instead of rectangular. Do not rely on duct tape alone to seal duct joints. Use sheet metal screws as required to support the duct.
WARNING:
For maximum ventilation performance, the bottom of the hood or liner should be 30 – 36 inches (76. 2 – 91. 4 cm) above the cooking surface (minimum is 24″). This would typically result in the bottom of the hood being 66 – 72 inches (167. 6 – 182. 9 cm) above the floor. These dimensions provide for safe and efficient operation of the hood. Always observe local building codes.
PART 2: SECURING THE LINER
TILE BACKSPLASHES
IMPORTANT: Liners installed immediately above the top edge of tile
backsplashes thicker than 3/4″ should be installed slightly forward–not flush
with the back wall. The back filter bracket of the liner is 1″ deep and tile
installations thicker than this will prevent the filters from being removable.
MOUNTING HOLES
NOTE: DRILLING THROUGH STAINLESS STEEL REQUIRES A TITANIUM BIT. BE CAREFUL NOT
TO DRILL THROUGH FILTER BRACKETS, ELECTRICAL COMPONENTS OR UL LABEL. Because
the TRADE-WIND® VSL Series is designed for various wood hood applications, no
mounting holes have been pre-drilled. This allows the liner to be attached in
most any area of the canopy that has a wood frame support, e. g. , the back,
sides or top. We recommend at least six equally spaced screws per liner–three
screws along the back (top or back side panel) and three screws on the front
top, immediately next to the light bar wall or behind the removable light bar.
Where possible, the screw holes should be drilled into the top of the liner
(instead of the sides or back). This will help prevent distorting the liner
walls in situations where the wood frame is not properly sized to the liner.
Models with internal motors should also have at least one screw centered and
securely in place on each end (side panel) of the liner because of the added
weight.
Neatly measure and mark (left to right and top to bottom) and drill screw
holes through the liner as required to match the wood backing. It is easier to
drill holes from the outside in, by setting the liner on its face (on
cardboard) and drilling from the back side. Secure the liner by driving screws
(by others) tightly into the wood frame. Use washers where necessary.
*When removing the filters, be careful not to scratch the liner by placing the filters, screws, drill bits or drill on the liner’s face. For visual instructions on removing the filters for mounting and other liner questions, check out our YouTube Channel: https://www. youtube. com/channel/UCwVIbi_9hbuIATTYvz43oBA.
CONNECTING TO THE VENT PIPE
The VSL liner comes with a metal start collar welded in place. Attach the
Start Collar to the duct with at least three equally spaced screws. Also apply
duct tape, preferably the metal type.

PART 3: ELECTRICAL CONNECTION
IMPORTANT: COPY THIS PAGE TO YOUR ELECTRICAL INSTALLER.
WARNING:
Ensure that the power supply is disconnected before proceeding. Verify that
the power supply matches the ratings found on the appliance data label before
proceeding. The complete appliance must be properly grounded at all times when
electrical power is applied. Do not ground the appliance with the neutral
(white) house supply wire. A separate ground wire must be utilized. Failure to
complete electrical connections properly may result in damaged or non-
functional systems. Follow instructions carefully to ensure proper
installation.
It is the owner’s responsibility to ensure that a qualified person performs
the electrical connection of this appliance. The electrical installation,
including minimum supply wire size, must comply with the National Electric
Code ANSI/NFPA 701990 (or latest revision) and local codes and ordinances. A
copy of this standard may be obtained from:
National Fire Protection Association, 1 Batterymarch Park, Quincy,
Massachusetts 02269-9101
INSTRUCTIONS: A 15 to 20 amp electrical service is recommended for proper
electrical supply. Before determining, calculate amp ratings based on the
product label found on the liner and the ventilator. Always observe local
building codes. Always use a dedicated circuit. Line load is calculated by
adding the amperage of the halogen lights to the rated amperage of the
ventilator (either in-line or roof top). If the ventilator is rated in watts
rather than amps, divide the watts by 120 and this will give you the amperage
rating. The TRADE-WIND® liner, without the internal motor, is supplied with a
6. 0 amp variable speed fan control. Make sure the rated amperage on the
remote ventilator does not exceed 6. 0 amps (or 700 watts).
CAUTION: The neutral wire (usually white) for the blower/motor must connect to
the same neutral wire that comes
from the electrical panel to the liner.

PART 4: USE AND CARE
CAUTION: The edges of the stainless steel are extremely sharp. To ensure
safety, wear gloves when handling all parts.
WARNING: Do not operate the blower/ventilator system without the filters in
place, or with dirty, grease laden filters.
FILTER REMOVAL:
Each filter has two aluminum cylindrical knobs, one towards the rear and one
towards the front. The front & rear knobs are only for grasping and are
permanently connected to the filter. To remove the filter, grasp the front &
rear knobs, pull the filter towards the front of the hood until the back of
the filter drops down. Grasping the filter, remove it from the front by now
pulling it out of the front channel. For visual instructions on how to remove
the filters, visit our YouTube Channel: https://www. youtube.
com/channel/UCwVIbi_9hbuIATTYvz43oBA.
OPERATING CONTROLS:
Always activate the ventilator when using cooking appliances. For best
performance, turn on the blower a few minutes before starting to cook to
establish an airflow pattern within the room. To use the electronic touch
control, touch the button that corresponds to the desired speed. To turn off
blower, touch the illuminated speed button again. The electronic light control
comes on when touched, touch again for light off.
ENERGY SAVING TIPS:
Eliminate air currents in the liner vicinity by shutting nearby windows and
doors, turning off ceiling fans and adjusting the adjacent heating and air
conditioning outlets if necessary. Place your largest pans on the rear burners
whenever possible. Clean filters and grease laden surfaces often to improve
efficiency. Always use lids on cookware to retain heat and moisture. Minimize
the amount of liquid used to cook food. Select cookware of proper size,
material and construction for the cooking task being performed.
CARE AND CLEANING:
Proper cleaning is necessary to maintain performance and appearance, while
also ensuring safe operation. The frequency of cleaning should be according to
the type and amount of cooking. Best results will be achieved by cleaning
soiled components as soon as possible. Filters must be cleaned regularly.
We recommend washing filters by placing them in the bottom rack of a
dishwasher. Locate the holes on the sides of the filter. Put filter in
dishwasher with holes facing up, so detergent can enter filters. Dry the
filters completely before using again. Rinse and dry with a soft lint-free
cloth. Always wipe stainless steel surfaces with the grain. Never wipe across
the grain. After cleaning, reinstall the filters carefully. Most common
scrubber type pads will scratch the hood.
CAUTION: If a commercially available stainless steel cleaner is used, it is
important to read the labels for chlorine
compounds. Chlorine is a corrosive substance, DO NOT USE. Follow polish
manufacturer’s instructions.
LED LIGHT BULBS:
TRADE-WIND® liners are designed for MR16/GU10 LED light bulbs. They can be
purchased at most home or grocery stores. The bulbs provided with the unit are
3. 5 watt, 350 lumens, and 3000K (warm white color temperature). To remove the
light bulbs, press your palm into the lens face of the bulb and turn a ¼ turn
to the left. The bulb should unlock from its socket, and pop out. If you need
to get more leverage on the bulb, you can purchase a suction cup with a ring
on it at your local hardware store.

EXPLAINING THE REMOTE
The diagram to the left shows all functions of the remote. Push the speed or
light buttons once to turn on; push the same button a second time to turn off.
You can use the “off” button to power off the lights and blower
simultaneously.
The “5 minute delay auto off” button can be pressed when the blower is on at
any speed. The blue light behind the speed button will blink showing that this
feature has been activated. It will continue to blink for 5 minutes and then
the blower will shut off automatically. If you press the “5 minute delay auto
off” button again the blinking on the speed button stops and the blower has
returned to manual mode.
If you would like to mount the remote to any surface near your range, Velcro
pieces have been provided. Peel and stick one piece to back of remote, and the
other to desired surface.
If battery in remote needs replacing, use a CR2025 watch battery. These are
very common and easy to find. To access, look to the bottom end of the remote;
push release to the right, and slide battery tray out.
RANGE OF REMOTE CONTROL
The infrared transmitter at the top of the remote must be pointed in the direction of the electronic control at the right front of your hood or liner. Range distance will vary depending on your installation, but see diagram below for approximate range area.

BEST PRACTICES
VENTING INSTALLATION INSTRUCTIONS FOR RANGE HOODS AND WOOD HOOD LINERS (ALL MODELS)
PERFORMANCE · QUALITY · CUSTOMER SERVICE
REVISED: APRIL 1, 2023
ADDENDUM TO INSTALLATION INSTRUCTIONS
IMPORTANT: Problems caused by the improper installations are not covered by
the manufacturer’s warranty.
IMPORTANT: Undersized and improperly installed duct pipe and/or other
ventilation components will cause
excessive static pressure (air resistance), that may result in rattling,
vibration and air buffeting noises, as well as inadequate ventilation.
1. BUILDING CODES
Kitchen hood/liners should be installed by qualified technicians familiar with
state and local building codes.
2. DUCT PIPE & FITTINGS (ELBOWS, TRANSITIONS, ROOF & WALL CAPS)
a. ) Use round or rectangular rigid metal duct only. Where possible, use round
duct as it creates the least amount of static pressure. IT IS RECOMMENDED THAT
YOU DO NOT USE FLEX DUCT
b. ) All duct sections and fittings, should overlap and be connected with at
least 3 4 equally spaced screws and wrapped tightly with 2 3 layers of
Aluminum Foil Metal Duct Tape. This type of duct tape is more durable than
traditional cloth duct tape. DO NOT USE BUTT JOINTS.
c. ) For best air flow, elbows and pipe size transition fittings should not be
directly connected to one another. Where possible, always include at least 15
inches of straight pipe between fittings.
3. DUCT PIPE & FITTING SIZES (See Duct Sizing Chart and Area Calculations
section on page 3 for more details)
IMPORTANT: The required duct size is indicated by the size of the duct collar
on the hood or liner.
IMPORTANT: No portion of any length of duct pipe or fitting should be smaller
than the duct collar of the hood/liner.
This is very important because any type of restriction anywhere in the
ventilation system will cause increased static pressure (air resistance), that
may result in rattling, vibration and air buffeting noises, as well as
inadequate ventilation.
DUCT RUNS – LENGTH
a. ) Configure the ventilation duct run to be as short and as direct to the
outside as possible. Minimize the number of elbows and transition fittings
used. Complex or long runs should be reviewed by a qualified installer.
b. ) No portion of the ducting should be run so that the exhaust air flows
downward. Since exhaust heat rises, forcing the air to flow downward will
cause increased static pressure. As previously mentioned, improperly installed
duct pipe will cause excessive static pressure (air resistance), that may
result in rattling, vibration and air buffeting noises, as well as inadequate
ventilation.
c. ) Duct runs for 390 CFM hood/liner models should not exceed 20 linear feet
with two 90-degree elbows (or four 45degree elbows), a damper and a roof or
wall cap. Longer runs or additional elbows will result in decreased
ventilation performance. Each 90-degree elbow is the equivalent of 8 linear
feet of duct pipe; each 45-degree elbow is equivalent to 4 linear feet of duct
pipe.
PROVERBS 22:29
9
©2023 TRADE-WIND MANUFACTURING, LLC
d. ) Duct runs for 600 1200 CFM hood/liner models should not exceed 35
linear feet with two 90-degree elbows and two 45-degree elbows, a damper and a
roof or wall cap. Longer runs or additional elbows will result in decreased
ventilation performance. Each 90-degree elbow is the equivalent of 6 linear
feet of duct pipe; each 45-degree elbow is equivalent to 3 linear feet of duct
pipe.
e. ) Always run hood/liner ducts to the outdoors. DO NOT terminate a duct into
an attic, basement, garage, crawl space under a house, a chimney, other
ducting or an enclosed room.
4. DAMPERS
IMPORTANT: DO NOT USE SCREWS TO ATTACH ANY TYPE OF DAMPER AS THE SCREWS MAY
BLOCK THE DAMPER
BLADES.
IMPORTANT: DO NOT USE MORE THAN ONE DAMPER IN THE VENTILATION SYSTEM.
NOTE: Many styles of roof caps and wall caps have built-in dampers. See Roof
Caps and Wall Caps section for more detail. Always use carefully crafted,
tightly wrapped Aluminum Foil Metal Duct Tape on all connections and
physically view and test the damper blades to make certain they are opening
and closing correctly. Make sure that the damper blades do not touch the duct
walls and that there is no debris blocking the free movement of the damper
mechanism. Common things to look for include screws protruding into the
blade’s path, overspray of paint, plaster and insulation. If using rectangular
duct, be sure that all four sides of the duct are on the outside of the
damper’s duct collar or frame. On hood/liner installations designed to
recirculate the exhaust air back into the kitchen, be sure to remove the
aluminum damper blade before attaching the duct to the damper frame.
a. ) 390 CFM Models 390 CFM models have either a 3. 25″ x 10″ rectangular
metal damper attached directly to the hood/liner or a 7″ duct collar that
requires a 7″ damper (sold separately).
b. ) 600 1200 CFM Models 600-1200 CFM models have either an 8″ or 10″ round
duct collar that requires use of a damper with the corresponding dimension
(sold separately).
Damper in Roof Cap or Wall Cap: In ventilation systems utilizing a roof cap or
wall cap with a built-in damper, do not install an additional in-line damper.
Two dampers are unnecessary and will cause increased static pressure (air
resistance), that may result in rattling, vibration and air buffeting noises,
as well as inadequate ventilation.
In-line Damper: In cold weather areas, installing an “in-line” damper may be
the preferred type of installation. This is because in-line dampers installed
just above the perimeter of the heated space (the ceiling) will reduce the
amount of cold air traveling down the duct into the heated space and into the
kitchen through the hood/liner. In-line dampers must be installed so that the
exhaust air-flow will open the butterfly blades.
Horizontal duct runs: The in-line damper must be installed so that the hinge
between the two butterfly blades is vertical–the hinge pin must point up and
down. Otherwise, because of gravity, the damper’s blades will not close and
the damper will not prevent backdrafts.
Vertical duct runs: The in-line damper’s hinge will be horizontal (sideways),
which is correct for vertical duct runs. Gravity will help close the damper
blades after each use.
Upward slanted duct runs: The in-line damper’s hinge must point to the top and
bottom sides of the duct. In his position, gravity will help close the damper
blades after each use. Otherwise, because of gravity, the damper’s blades will
not close and the damper will not prevent backdrafts.
PROVERBS 22:29

5. ROOF CAPS & WALL CAPS
The roof cap or wall cap is the termination point of the venting system that
allows the exhaust air to exit to the outdoors. All sections of this fitting
must have an equal or greater air path area than the hood/liner’s duct collar.
If any section of the roof cap or wall cap is smaller than the hood/liner’s
duct collar, the entire ventilation system will lose performance and the
restriction will cause increased static pressure.
IMPORTANT: Even though the intake side of the roof cap or wall cap may be
properly sized, roof caps or wall caps
with built-in dampers must be made so that when the damper is fully open, the
actual open area of the exit point is equal to or greater than the duct collar
of the hood/liner. Any undersized portion of a roof cap or wall cap will cause
excessive static pressure that may result in rattling, vibration and air
buffeting noises, as well as inadequate ventilation. ROOF CAPS AND WALL CAPS
MUST HAVE AN INTEGRAL BIRD SCREEN.
ROOF CAP DRAWING: RECOMMENDED & NOT RECOMMENDED
No Mushroom Cap Style
No “Goose-Neck” Style
6. ATTACHING DUCT TO HOUSE FRAMEWORK
Only use a shape that looks like the picture shown. Call TRADE-WIND® Customer Service for any questions.
The ventilation system should be attached to the framework in such a manner that the weight of the duct and fittings is supported with no stress on the duct joints, fittings or on the hood/liner. All ducting should be attached so as to avoid any possible duct vibration from being transferred to the house’s framework.
