• An IVS installed in a custom hood canopy that is constructed with a Dacor IHL series stainless steel hood liner must be installed with the non-combustible material structure a minimum of 30” (76.2 cm) above the appliance cooking surface.
• The IVS must be mounted so that it can be removed if service is required. Make sure that the material around the edge of the cutout, behind the IVS mounting holes, is strong enough to hold the weight of the unit.

Electrical Requirements

WARNING
To reduce the risk of fire and electric shock:

• The electric service to the integrated ventilation system must be installed only by a licensed electrician.
• When installing models IVSR1 and IVSR2, install ONLY the in-line or remote blower models specified in these instructions.
• Install models IVSR1 and IVSR2 only with in-line or remote blowers with a total rated maximum of 8 Amps.

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 (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 ground wire on this appliance must be connected to a grounded, metallic, permanent wiring system or grounding conductor installed by a licensed electrician.
• Do not ground the appliance or appliance wiring to a gas pipeline or to the neutral (white) power supply wire.
• Do not install a fuse in the neutral or ground circuit.
• Connect the IVS directly to an electrical junction box.
• The IVS needs to be hard wired, according to local code, directly to a dedicated three wire grounded, single phase circuit rated at 120 Vac 60 Hz, 15 Amps.

Planning the Duct Work
WARNING

• To reduce the risk of fire and to properly exhaust air, be sure to duct air outside the house or building. Do not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces or garages.
• To prevent combustion by-products, smoke or odors from entering the home and to improve efficiency, tape all duct joints securely.
• Use only duct work deemed acceptable by state, municipal and local codes.
• Range hoods may interrupt the proper flow of smoke and combustion gases from furnaces, gas water heaters and fireplaces. To avoid drawing lethal gases into the home, follow the manufactures recommendation for these devices and consult NFPA and ASHRAE recommendations.
• When installing models IVS1 and IVS2, DO NOT install an additional, external blower to increase the length of the duct run. Even small differences between blower air flow rates can greatly reduce the air draw by the hood.
• When installing models IVSR1 and IVSR2, DO NOT install more than one external blower per duct run to increase the length of the duct run(s). Even small differences between blower air flow rates can greatly reduce the air draw by the hood. Install ONLY the in-line or remote blower models specified in these instructions.

Duct System Design Requirements

• All duct work materials (including screws and duct tape) must be purchased separately by the customer.
• Ducts must be of adequate size and duct runs should be as short and straight as possible. Where turns are necessary, keep the turning radius as large and smooth as possible.

Installation Requirements

• To prevent back-drafts, a damper at the duct outlet may also be required. The IVS comes equipped with a backdraft damper installed in the collar of the unit.

• Make sure duct work does not interfere with floor joists or wall studs.

• The hood exhaust connects to a 8-inch round duct. You can increase the duct size over the duct run if desired.
  To prevent a back draft, never decrease the duct size over the run. If existing duct work is smaller than 8 inches in diameter, remove it and replace it with 8-inch or 10-inch duct work.

• On dual exhaust models, the two 8 inch exhausts may be merged into on 10 inch duct using Dacor transition ATD10.

• Do not rely on tape alone to seal duct joints. Fasten all connections with sheet metal screws and tape all joints with certified silver tape or duct tape. Use sheet metal screws as required to support the duct weight.

• Do not use flexible metal duct.

• Do not use duct work that is smaller in cross-sectional area than 8-inch round duct.

Additional Requirements for Models IVSR1 and IVSR2:
Models IVSR1 and IVSR2 are not equipped with an internal blower. Installation of an in-line or remote blower is required. See the table below for the correct model number.

Calculating the Maximum Duct Run Length
The maximum straight duct length for the hood is determined by the type of duct used. See the chart below.

For each elbow and transition added to the duct work, a certain number of feet must be subtracted from the maximum duct run to compensate for wind resistance. To determine the length the duct work cannot exceed, subtract all of the equivalent lengths of the elbows and transitions listed below from the maximum duct run above.

Duct Work Equivalent Lengths

• The equivalent lengths of roof and wall caps vary with model and configuration.

Duct Work Design Tips
When planning new duct work, always look for the shortest, most direct route to the outside.
Wherever possible, reduce the number of transitions and turns to as few sharp angles as possible. Two staggered 45° angles are better than one 90°.
Keep turns as far away from the hood exhaust as possible, and as much space between bends as possible.
For best performance, use round duct instead of rectangular, especially when elbows are required.
If multiple elbows are used, try to keep a minimum of 24 inches of straight duct between them. Avoid “S” or “back to back” use of adjacent elbows.
In regions where the weather gets extremely cold, use thermal breaks, such as a short section of non-metallic duct, to avoid indoor heat loss. Locate the break as close as possible to the outside pass through point.

Installation Instructions

Installing the IVS
WARNING
To avoid an electric shock hazard, do not connect the wiring harness until after the IVS is installed in the cutout and the duct work is installed.

1. If installing a hood liner (Dacor series IHL) install it before installing the IVS.
2. Remove the filters from the IVS.
3. The IVS comes pre-wired from the factory. Insert the unit into the cutout while routing the wiring harness to the junction box.
4. While holding the IVS in place, attach it to the cutout with screws (not supplied) through the mounting holes around the edge.

Installing the Duct Work
WARNING
During duct installation, make sure there are no obstructions that keep the damper flaps on the top of the IVS from opening.

1. Models IVSR1 and IVSR2 only: Install the remote or in-line blower (see page 5 for specifications) according to the blower installation instructions.
2. Install the duct work starting from the hood working toward the outside vent. Observe the specifications on pages 4 and 5. Fasten all joints with sheet metal screws and seal with duct tape or certified silver tape. The duct work must be air tight. Use a minimum of two (2) sheet metal screws at every duct joint. Seal all duct joints with a high quality duct tape.

Electrical Connection
WARNING

• To avoid electric shock or fire hazard, prior to connecting the electrical wiring to the hood, make sure that power to the IVS power supply line is turned off at the fuse box or circuit breaker panel.
• Improper connection of the hood electrical wiring may create an electric shock or fire hazard and may result in damage to the hoods electrical system.
• Do not ground the hood to the neutral (white) power supply wire. Connect the hood ground wire to a separate, properly grounded wire installed by a licensed electrician.
• Make sure all wire used is capable of handling the total connected load. See page 3.
• If aluminum house supply wiring is used, splice the appliance copper wires to the aluminum house wiring with special connectors designed and agency-certified for this purpose. Follow the connector manufacturer’s recommended procedure carefully.  Improper connection can result in a fire hazard.

1. Models IVSR1 and IVSR2 only: Route the wiring from the in-line or remote blower into the IVS through one of the electrical access holes in the hood. Connect them to the remote blower (REMP) connection terminal as shown below. Match wire colors.
2. Connect the pre-wired, white and green wires to the corresponding black, white and ground (green) wire from the power source wiring. Use wire nut connectors to secure the connections.

Verifying Proper Operation

1. Install the filters.

2. Install the light bulbs.
   • Attach the included suction cup to one of the provided light bulbs.
   • Insert it into one of the light fixtures.
   • Screw it into place and remove the section cup.
   • Repeat for the remaining light fixtures.

3. Verify that the IVS control knobs are in the OFF position (fully counter-clockwise).

4. Turn on the main power supply at the circuit breaker panel or fuse box.

5. Turn the light and fan knobs clockwise and make sure the lights and fans operate properly.

If the hood does not operate properly, follow these troubleshooting steps:

• Verify that power is being supplied to the IVS.
• Check the electrical connections to ensure that the installation has been completed correctly.
• Repeat the above test.
• If the installation still does not work, contact Dacor Distinctive Service at 800-793-0093, extension 2822.
  Do not attempt to repair the unit yourself. Be sure to have all model and serial numbers from the product data labels available when you call.
