only metal duct work to install raised vents.

f) For general ventilating use

only. Do not use to exhaust hazardous or explosive materials and vapors.

WARNING:

TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK.

WARNING:

Improper grounding can result in a risk of electric shock.

• Consult a qualified electrician if the grounding instructions are not completely understood, or if doubt exists as to whether the appliance is properly grounded.

• Do not use an extension cord. If the power supply cord is too short, have a qualified electrician install an outlet near the appliance.

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”

WARNING:

TO REDUCE THE RISK OF FIRE, ELECTRIC 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.

b) Sufficient air is needed

for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment manufacturer’s guidelines and safety standards such

CAUTION:

To Reduce the Risk of Fire And Electric Shock, Install This Downdraft Ventilation Unit Only with Remote Blower Models Rated Maximum 8 Amp (total of all interconnected remote blowers).

GROUNDING INSTRUCTIONS

• This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet this is properly installed and

grounded.

Electrical Power Supply Requirements

It is the owner ’s responsibility to ensure that the electrical connection of this appliance is performed by a qualified electrician. The electrical installation, including minimum supply wire size and grounding, must be in accordance with the National Electric code ANSI/NFPA 702002* (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

The correct 120VAC, 60Hz, 15A circuit must be supplied for this appliance from a separate, grounded, circuit that is protected by a properly sized circuit breaker or time delay fuse.

Duct Planning

WARNINGS

1. To reduce the risk of fire and to properly exhaust air, ducted fans must be vented to outside. Do not vent exhaust air into spaces within walls, ceilings, attics, crawl spaces or garages.

2. Improper installation, adjustment, alteration, service, or maintenance can cause personal injury or property damage.

3. To reduce the risk of fire, use only ductwork materials deemed acceptable by state, municipal and local codes.

NOTES:

1. Best performance is achieved by using round duct instead of rectangular, especially when elbows are required.

2. If multiple elbows are needed, ensure that there is a minimum of 24” of straight duct between any two elbows.

3. Avoid “S” or “back to back” configurations caused by adjacent elbows.

4. Thermal breaks, such as a short section of non-metallic duct, should be used in areas of extreme cold.

5. A back-draft damper at the duct outlet may also be required.

6. Do not use flexible metal duct.

7. Do not use ductwork that is smaller in cross-sectional area than the recommended size duct.

8. Do not rely on duct tape alone to seal duct joints. Use sheet metal screws as require to support the duct weight.

9. The raised vent and cooking appliance(s) must be removable if service is required.

10. Be certain that the ductwork does not interfere with floor joists or wall studs.

11. It is important to keep a minimum number of turns in the duct run, and to keep the run as short as possible.

12. Do not restrict the air flow by reducing the duct crosssectional areas when making hard joints or squeezing through a tight area.

13. With concrete slab construction, "box-in" the ductwork to prevent it from collapsing when the wet concrete is poured. Also allow room for electrical conduit.

14. Cross-drafts or air currents caused by adjacent open windows or doors, HVAC outlets, ceiling fans, and recessed ceiling lights reduce vent efficiency.

Sample problem:

Given a remote system installation having 20 feet of 3 ¼” x 10” rectangular duct, one (1) 90-degree 3 ¼” x 10” elbow, and one (1) 3 ¼” x 10” to 8” or 10” round transition, would this installation be proper? Solution:

1. Add the total length of straight duct: 20’ (of 3 ¼” x 10”) = 20’.

2. Using Table above, determine the equivalent straight length of all duct fittings: 90-degree 3 ¼” x 10” elbow = 15’. 3 ¼” x 10” to 8” or 10” round transition = 4’.

3. Add (1) and (2) to determine the total equivalent straight length of the complete duct system: 20’ + 15’ + 4’ = 39’ total equivalent straight duct length.

4. For the remote system with 3 ¼” x 10” duct, the maximum allowable total equivalent straight length of duct is 40 feet. Thus, this proposed installation is proper.

After determining that your proposed ductwork meets the maximum duct length requirement, proceed with the location planning.

Higher volumes of air exhausted by the vent system result in better overall removal of smoke and fumes from the kitchen. Longer duct runs and greater numbers of duct transitions reduce air volume, therefore it is extremely important

to keep duct runs as short and straight as possible.

To ensure that your installation meets this requirement, add the actual straight length of duct to the equivalent straight length of all duct fittings to determine the total equivalent straight length of duct. (Refer to the table above, which shows various common duct fittings with their equivalent straight lengths for various common duct sizes). If this total equivalent straight length is less than or equal to the maximum limits specified, then the installation is proper. Consider the duct size that corresponds to the majority of the duct used in the installation.
