INTRODUCTION GENERAL DESCRIPTION

The complete downdraft system consists of the downdraft, a blower and a transition box if using an Inline or Remote Blower. A recirculation module is also available when ducting to the outside is not preferred or not possible. (See Fig. 1). The blower can be either integral (mounted on the vent intake in the cabinet under the cooktop), an inline (mounted between the kitchen and exterior wall anywhere within the duct line), or a remote (mounted on the roof or outside wall). When a remote or inline blower is used, a duct transition is mounted on the ventilator intake in place of the integral blower to connect the intake to the duct work. The duct transition must be purchased separately.

The integral blower or duct transition can be mounted in different positions on the intake to route ductwork to avoid cabinet, building framing, utilities, etc.

The downdraft system is available in 30inch or 36- inch. Intended for non-professional style cooktops only.

A Recirculation Kit can be purchased separately and used in conjunction with the Integral Blower if ducting to the outside is not a viable option.

Step 1: Plan the installation

Carefully follow the planning procedures listed below (See Figure 2). Sketches are NOT intended to be a replacement for careful planning.

A. Determine whether a remote, inline, or

integral blower will be used. Remote

and inline blower installation requires 4 wires plus a ground wire to run from the downdraft to the blower.

B. Make sure that adequate cabinet and

counter space has been provided and that the intake and blower will be accessible if service is required.

C. Consider that cross drafts created by

adjacent open windows, doors, air conditioning, old heating vents, recessed ceiling lights, and trafﬁc patterns may affect performance.

D. For gas cooktop installations make sure

that a minimum 10 square inch opening is provided in the toe-kick or other cabinet area. Inadequate ventilation of the cabinet below the cooktop may result in ﬂame outage when operating the vent system.

E. Provide for air supply or ”make-up

air” to the room where unit will be installed. If ”make-up air” is not provided, then problems, such as ﬁreplace chimney downdrafts, could result.

F. Investigate potential ductwork routes

and choose the shortest possible route from the unit to an outside wall or to the roof via an inside wall and attic. For guidance, typical ducting installations are shown in ﬁgures 3 through 6. Installation in island locations will require under ﬂoor ducting. Peninsula locations usually require ducting laterally through cabinets or under cabinet toe spaces. Consider potential interferences to ductwork from building framing (ﬂoor joists, wall studs, etc.) and utilities (electrical wiring, water, gas, or sewer lines, etc).

G. Purchase the necessary ductwork as

needed to duct to the outside or purchase separately the downdraft Recirculation Module if ducting to the outside is not a viable option.

• Be certain to avoid interference with gas and electric supply to cooktop.

• Shelving and drawer depths are dependent upon cooktop depth and setback.

DUCTWORK INSTALLATION GUIDELINES

G Ducting should vent directly outdoors

(not into an attic, underneath the house, into the garage or into any enclosed space). A Recirculation Module is available when ducting to the outside is not possible.

G Keep duct runs as short and straight as

possible.

G Duct ﬁttings (elbows and transitions)

reduce air ﬂow efﬁciency.

G Back to back elbows and ”S” turns give

very poor delivery and are not recommended.

G A short straight length of duct at the inlet

of the remote blower gives the best delivery.

G Transition to duct from the integral blo-

wer or remote duct transition as close to the downdraft as is possible. In order of preference, use

1st. 10” round duct 2nd. 8” round duct 3rd. 3-1/4” x 14” duct 4th. 7” round duct 5th. 3 -1/4” x 10” duct 6th. 6” round duct

G The use of ﬂexible metal round duct

should only be used when no other duct ﬁtting exists. Limit use to short lengths and do not crush when making corners.

G Back to back elbows should be avoided.

DUCTWORK INSTALLATION GUIDELINES

G Where local codes permit, plastic pipe

(PVC-schedule 40 pipe or ABS pipe 7” or 8” diameter) can be used in areas of high ground moisture and in slab ﬂoors to eliminate future rusting.

G Use only duct work constructed of mate-

rials that are acceptable by the applicable codes. All duct should be 26 gauge or heavier to minimize ﬂex due to air ﬂow.

G The remote blowers require a 10” or 6”

diameter round duct (depending on model) to match the inlet ring. A transition is necessary from other duct sizes.

G Use sheet metal screws as required to

support the duct weight, and seal all joints with duct tape.

G Be certain that the duct work does not

interfere with ﬂoor joists or wall studs.

G Do not exhaust more than one vent into

a single duct run.

G Cold weather installations should have

an additional backdraft damper installed to minimize backward cold air ﬂow and a nonmetallic thermal break to minimize conduction of outside temperatures as part of the ductwork. The damper should be on the cold air side of the thermal break. The break should be as close as possible to where the ducting enters the heated portion of the house.

G Always use an appropriate roof or wall-

cap with damper. Laundry type wall caps should never be used.

Step 2: Prepare Countertop Cutout

Refer to the cooktop installation instructions for dimensions of cooktop, countertop cutout, and cabinet requirements prior to making any cutouts. Cooktop depth and countertop back-splash depth can vary greatly from one to another. These variations may cause the ﬁt of the downdraft and cooktop to be tight. A countertop (front edge) with a raised lip and/or a wide backsplash (back edge) may not allow enough ﬂat countertop for a proper installation.

Y Check that the cooktop is far enough

forward that the downdraft will ﬁt behind it. Verify all dimensions prior to cutting the countertops.

Use the physical products to conﬁrm cutouts whenever possible.

For all installations verify that all cutouts will clear the inside of the front countertop support rail, and that the cooktop and vent will be centered left to right within the cutout. Also, make certain that the front

and rear cutouts are straight and parallel to the front edge of countertop and the rear backsplash and/or wall. Assure that the side cutouts are square to the front and rear cutouts.

All illustrations and dimensions are based on standard 24” deep by 36” high American style base cabinets with 25” countertops.

When installing laminated or solid surface countertops such as Surell™ and Corian

, be sure to follow the countertop manufacturer’s instructions regarding minimum comer radii, reinforcement of corners, etc.

Note: Check boxes as tasks are completed.

For overhead cabinet and cooktop side clearances consult cooktop Installation Instructions.

Notes

Dimension ”SB” is the minimum distance from the leading edge of the counter to the leading edge of the cutout.

Dimension ”BT” is the thickness of backsplash that provides 1/4” clearance between vent and backsplash. Any backsplash with a curved radius where it meets the counter will require additional clearance. Thicker backsplashes may be used by increasing the counter and cabinet depths.

Set the cooktop into the countertop opening so that the back edge of the cooktop overlaps the leading edge of the downdraft.

Step 3: Prepare Duct Cutouts in Cabinet

Y A. Refer to Figure 8. Drop a plumb-line

from Point ”P” at the rear center of the countertop cutout. Mark this point on the bottom of the cabinet below. Construct two reference lines through this point: one should be parallel to the cabinet front and directly below the rear countertop cutout (Line A-A), and the other (Line B-B) should be at right angles to A-A.

Y B. Using these reference lines as a base

for the measurements, layout the necessary cabinet cutouts needed to implement the planned ductwork route. Where a range of measurements is noted, choose a measurement that allows best clearance from wall studs, ﬂoor joists, utilities, or other obstructions.

Step 3: Prepare Duct Cutouts in Step 3: Cabinet

Y C. Before cutting for ducting, temporarily

set intake and cooktop in place and attach integral blower (or duct transition ﬁtting if a remote or inline blower is installed). Refer to steps 6 and 7. Verify that the duct cutouts as marked will match the hardware installation. Adjust the duct cutout as necessary to match hardware installation.

Y D. Remove temporarily placed hardware

and make cutouts in cabinet to accommodate ductwork installation.

Y E. Make all other cabinet modiﬁcations

needed to provide proper clearances for drawers or removable shelving.

Note: Check boxes as tasks are completed.

Step 4: Install Ductwork (Remote or Inline Blower, If Used)

Y A. Install the ductwork and remote blo-

wer (if used) in accordance with the ductwork routing plan developed in Step 1.

Y B. Make sure that the installation com-

plies with all installations guidelines. Type and length of ducting and lack of makeup air may reduce CFM. Also check that the opening where duct passes through outside wall or roof has been properly ﬂashed and sealed to prevent leakage.

Y C. If using Integral Blower, proceed to

Step 5.

Y D. If using Remote or Inline Blower, refer

to Installation Instructions with that model.

Step 5: Install Electrical Service

Y Check your local building codes for pro-

per method of installation. In the U.S., if there are no applicable local codes, this unit should be installed in accordance with the National Electric Code ANSI/NFPA No. 70, Current Issue. (In Canada, installation must be in accordance with the CAN 1-B149.1 and .2Installation Codes for Gas Burning Appliances and/or local codes).

Y The 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 that is properly installed and grounded.

몇 WARNING – Improper grounding can

result in a risk of electric shock. Only a qualiﬁed electrician, or similarly quali-

ﬁed persons, should make the electrical connections.

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

The receptacle should be located under the countertop so that the 30 inch long power cord from the vent will reach it. See Figure 8.

Y The cord should be routed beneath the

appliance and away from heat generated by the cooktop. Access should not be obstructed by blower, cabinet work, ductwork or electrical/gas utilities for the cooktop. All power for the vent system (including the remote blower, if used) is supplied via the cord to the intake unit. The outlet can usually be extended from another kitchen outlet or have its own circuit from the main service panel.

Do not plug vent cord into receptacle until Step 8.

Step 6: Mount Vent and Cooktop

Y A. Remove grease ﬁlters and any

packing materials from inside the intake.

Y B. Set the vent intake into rear of coun-

tertop opening. Carefully lower it into position so that the ﬂanges on the rear sides and edges fully support the unit hanging from the countertop.

Y C. Hold the unit against the rear of the

countertop opening, and slide the leg brackets down to meet the bottom of cabinet. Check and adjust for plumb, then fasten leg brackets to cabinet with hardware provided.

Note: Check boxes as tasks are completed.

Step 7: Mount Integral Blower or Outlet Duct Transition for Remote or Inline Blower

Integral Blower (see Figures 9 and 11 for

further detail): Y A. Attach blower in front of round

exhaust outlet with 4-6 (depending on conﬁguration) #8 sheetmetal screws.

Y B. Feed cord from blower through strain

relief.

Y C. Secure strain relief with screws. Y D. Attach strain relief to downdraft near

junction box.

Y E. Connect cord to downdraft at 6 pin
