PLANNING

This downdraft blower system is designed to be used to exhaust airborne contaminants when cooking with a variety of gas or electric cooktops. It can be mounted in island, peninsula, or conventional wall locations.
This unit can be easily installed following these basic steps:

Cut out the countertop opening.
Mount the unit in the cabinet.
Connect the ductwork and electrical.
Install the cooktop.

INSTALLER: Save this manual for Electrical Inspector and Homeowner to use.
HOMEOWNER: Use and Care Information on Page 5

Note: The high level of air flow of this appliance may affect the gas flame on some types of gas cooktops. This is NORMAL and will cause no harm, but can be corrected by lowering the speed of the blower.

TAKE MEASUREMENTS

Refer to the cooktop installation instructions for dimensions of cooktop, countertop cut-out, and cabinet requirements. The Model 2730 will fit in most 30″ wide cabinets and the Model 2736 will fit in most 36″ wide cabinets. However, it is recommended that oversized cabinets be used for easier installation.
Cooktop depth can vary greatly from one to another. This may cause the fit of these two appliances to be rather tight.

Pay special attention to the areas of potential interference highlighted above. A countertop with (A) a raised lip and/or (B) a backsplash may not allow enough flat countertop for a proper installation. Note that 2″ of flat countertop is required behind cooktop and that 1-3/4″ is necessary between the back edge of the cooktop and the inside of cabinet back.

PLAN THE DUCTWORK

Plan The Ductwork

This downdraft blower system is designed for use with 3″ x 10″ ductwork (can be transitioned to 6″ round). Three different discharge directions are available with side-to-side adjustment for accurate alignment of ductwork.
For best performance: Choose the ducting option which allows the shortest length of ductwork and a minimum number of elbows and transitions. Check location of floor joists, wall studs, electrical wiring or plumbing for possible interference. NOTE: The unit is shipped with the 3″ x 10″ discharge facing DOWN. See “CHANGING BLOWER DIRECTION” on page 3, if necessary.
The system will operate most efficiently when the ductwork does not exceed 40 feet of equivalent duct. The chart, above, shows equivalent feet of elbows and transitions. The number of feet of straight duct plus the equivalent feet of transitions and/or elbows to be used should equal 40 feet or less.

NOTE: The equivalent feet of various roof and wall caps has been taken into consideration. Do not include them in this calculation.

PLAN THE WIRING

The downdraft and exterior blower system draws 4 AMPS and requires a 120 VAC, 60 Hz circuit.
Plan to provide unit with grounded wiring which meets codes:

Note: Installations in which the fit between blower system and cabinet is tight. Consider running the wiring through a adjacent cabinet to prevent sharp bends in wiring.

PREPARATION

CHANGING BLOWER DISCHARGE (Optional)

The blower is shipped with its discharge facing DOWN. Follow these steps ONLY if

the position of the blower discharge needs to be moved so ductwork does not interfere with floor joists, plumbing or wiring below.
it is necessary to rotate the blower discharge to the RIGHT or LEFT.

Place the unit on its back on a table or work surface.

DOWN DISCHARGE – MOVING BLOWER LEFT OR RIGHT

Preparation

Loosen the 4 nuts and 2 clamp channels.
Slide blower to desired position.
Use supplied cover plate to close open space (if any).
Tighten nuts to secure top of blower and use sheet metal screws through bottom flange to secure bottom of blower.

LEFT OR RIGHT DISCHARGE

Remove the 4 nuts and 2 clamp channels.
Carefully lift blower and disconnect motor plug if necessary.
Reposition blower and RECONNECT MOTOR PLUG.
Use supplied cover plate to close open space (if any).
Replace clamp channels and use nuts to secure the blower in its new position.
Use sheet metal screws through bottom flange to secure bottom of blower.

CUT COUNTERTOP OPENING

Lay out and cut the cooktop cut-out far enough FORWARD so downdraft will fit behind it.
Set cooktop in place and slide it as far forward as possible.
Center and square it with edges of countertop
Place the plastic template against the back flange of the cooktop and center it. Trace around template to mark the downdraft opening.
Remove cooktop from countertop.
Cut downdraft opening. Be careful not to chip edges of countertop

MOUNT THE UNIT

Mount The Unit

Set downdraft into opening. Extend leveling brackets to floor of cabinet so downdraft sits straight. (Note: Leveling brackets can be removed and re-attached in other positions. Bottom flange may have to face inward in tight cabinet installations.)
Secure the downdraft to the countertop as follows: Hold the downdraft against the back of countertop cut-out and tightening the 2 mounting screws (one on each end of unit) on underside of countertop. Use a wood shim between screws and underside of granite countertops.
Screw leveling brackets to bottom of cabinet. Tighten screws holding leveling bracket to unit on each side.

INSTALL DUCTWORK

CAUTION – BEFORE CUTTING HOLE IN CABINET FOR DUCTWORK: Check for interference with floor joists, wall studs, electrical wiring or plumbing.
Install Ductwork

Cut hole in cabinet as well as holes in wall or floor as necessary.
Mount the roof or wall cap and work back towards the cabinet, attaching all ductwork, elbows and transitions as previously planned. Tape all ductwork connections to make them secure and air tight.
Connect ductwork (and transition, if required) to downdraft. If necessary, LOOSEN nuts and screws that hold the blower in place, and slide blower left or right to meet ductwork. Retighten screws and nuts.

Note: A 3-1/4″ x 10″ collar is provided for installers who prefer to rivet the ductwork to the unit. This will allow blower to be removed and replaced easily in service situations without disturbing ductwork.

INSTALL ELECTRICAL WIRING

WARNING: To avoid possible electrical shock, personal injury or death – Disconnect electrical power.

Mount a standard wiring box, with 3-pronged receptacle, inside the cabinet. Make sure the downdraft’s power cord can easily reach it.
Run appropriate power cable into cabinet and connect it to receptacle.
Plug the downdraft’s power cord into the outlet

WIRING DIAGRAM

Wiring Diagram

INSTALL COOKTOP

Align the cooktop with the downdraft and fasten cooktop in place.

Note: Accurate alignment of cooktop and downdraft is necessary to ensure that there is no interference when air vent is raised and lowered. There should be a gap of 1/32″-1/16″ between the back of the cooktop and the front of the downdraft cover.

ADJUSTMENT

The downdraft is factory-adjusted for proper operation. However, shipping and handling may affect the position of the activating switch.
To adjust position of activating switch:

WARNING: To avoid possible electrical shock, personal injury or death – Disconnect electrical power.

If downdraft is plugged into electrical outlet, unplug it.
Lift air vent straight up and cock it slightly so it remains in the UP position.
Remove switch cover from right end of air vent.
Loosen the 2 screws holding the switch bracket in place.
Position switch bracket so that activating switch just comes in contact with underside of switch membrane. Tighten screws.
Replace switch cover, gently lower air vent into chimney, and plug in power cord. Re-connect electrical power and check operation.

USE AND CARE

Always turn the downdraft blower on before you begin cooking to establish an air flow in the kitchen. Let the blower run for a few minutes to clean the air after you turn the cooktop off. This will keep the whole kitchen cleaner and brighter.

CONTROLS

Use And Care

Turn the downdraft blower ON by pressing down on the activating switch. The air vent will rise.

The blower can be turned ON or OFF and its speed can be adjusted with the recessed knob on the right side of the air vent.

Turn the downdraft blower OFF by pressing the activating switch again. The air vent will go down and the blower will shut OFF.
Note: For most convenient operation, set the blower to your favorite speed. The blower will come on to this speed whenever the activating switch is pressed and the air vent rises.
