DO Venting system MUST terminate outside the home.
DO NOT terminate the ductwork in an attic or other enclosed
space.
DO NOT use laundry-type wall caps.
Flexible-type ductwork is NOT recommended.
DO NOT obstruct the flow of combustion and ventilation air.
Failure to follow venting requirements may result in a fire.
A 120 volt, 60 Hz AC-only electrical supply is required on a separate 15 amp fused circuit. A time delay fuse or
circuit breaker is recommended. The fuse must be sized per local codes in accordance with the electrical rating of
this unit as specified on the serial/rating plate located inside the unit near the field wiring compartment. THIS
UNIT MUST BE CONNECTED WITH COPPER WIRE ONLY. Wire sizes must conform to the requirements of the
National Electrical Code, ANSI/NFPA 70 - latest edition, and all local codes and ordinances. Wire size and
connections must conform with the rating of the appliance. Copies of the standard listed above may be obtained
from:
National Fire Protection Association
Batterymarch Park Quincy,
Massachusetts 02169
This appliance should be connected directly to the fused disconnect (or circuit breaker) through flexible,
armored or no metallic sheathed copper cable. Allow some slack in the cable so the appliance can be moved if
servicing is ever necessary. A UL Listed, 1/2” conduit connector must be provided at each end of the power
supply cable (at the appliance and at the junction box).
When making the electrical connection, cut a 1 1/4” hole in the wall. A hole cut through wood must be sanded
until smooth. A hole through metal must have a grommet.
CAUTION: To reduce risk of fire and to properly exhaust air, be sure to duct air outside - Do not vent exhaust air
into spaces within walls or ceilings or into attics, crawl spaces, or garages.
Determine which venting method is best for your application. Ductwork can extend either through the wall or the
roof. The length of the ductwork and the number of elbows should be kept to a minimum to provide efficient
performance. The size of the ductwork should be uniform. Do not install two elbows together. Use duct tape to
seal all joints in the ductwork system. Use caulking to seal exterior wall or floor opening around the cap.
Flexible ductwork is not recommended. Flexible ductwork creates back pressure and air turbulence that can
reduce performance.
Make sure there is proper clearance within the wall or floor for exhaust duct before making cutouts. Do not cut a
joist or stud unless absolutely necessary. If a joist or stud must be cut, then a supporting frame must be
constructed.
To reduce the risk of fire,
use only metal ductwork.

RECOMMENDATIONS AND SUGGESTIONS
Switch off or unplug the appliance from the main supply before carrying out any maintenance work.
Clean and/or replace the filters after the specified time period.
Clean the hood using a damp cloth and a neutral liquid detergent.
The range hood has been designed exclusively for residential use to eliminate kitchen odors.
Never use the hood for purposes other than for which it has been designed.
Never leave high open flames under the hood when it is in operation.
Adjust the flame intensity to direct it onto the bottom of the pan only, making sure that it does not engulf
the sides. Deep fat fryers must be continuously monitored during use: overheated oil can burst into
flames.
The hood should not be used by children or persons not instructed in its correct use.
The manufacturer will not be held liable for any damages resulting from incorrect or improper installation.
Check that the main voltage corresponds to that indicated on the rating plate fixed to the inside of the
hood
The electrical supply must be properly and sufficiently grounded.
Connect the liner to the exhaust duct through a pipe of minimum diameter 8” for 600 cfm models and 10”
for 1200 cfm models. The route of the duct must be as short as possible.
Do not connect the hood to exhaust ducts carrying combustion fumes (boilers, fireplaces, etc.).

Hood comes with liner installed. Carefully remove screws while holding the liner in place so it doesn’t fall forward
and damage your hood. Take liner out for installation of shell by removing the baffle filters and locate the bolts
on the L/R sides holding it in. Once liner is removed, place hood in the location you want it installed in, locate the
studs using a stud finder and secure the hood to the wall with appropriate bolts/lags (mounting hardware not
supplied due to various surface needing different requirements). Holes are provided in staggered design across
the bottom and top mounting bars for flexible mounting options regardless of where your studs are behind the
wall.
Ducting – Rear or Top Vent Options Ducting is brought into the hood from above or through the rear wall with a
90 degree transition (not provided). Measure proper length prior to installing liner and seal properly with duct
tape. Ensure you use 8” duct for 600 cfm models, and 10” duct for 1200 cfm models for the entire duct run, with
equivalent sized roof or wall caps to ensure best performance.
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.

BEST PRACTICES FOR INSTALLATION
Kitchen hood/liners should be installed by qualified technicians familiar with state and local building codes.
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.
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.
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.
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.
(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
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.
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.
Duct runs for 390 CFM hood/liner models should not exceed 20 linear feet with two 90-degree elbows (or
four 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 8 linear feet of duct pipe;
each 45-degree elbow is equivalent to 4 linear feet of duct pipe.
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.

4. DAMPERS
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.
• 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).
• 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 this 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.
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, over spray 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.
