Electrical requirements

IMPORTANT

Observe all governing codes and ordinances. It is the customer's responsibility:

To contact a qualified electrical installer. To assure that the electrical installation is adequate

and in conformance with National Electrical Code, ANSl/NFPA 70 -- latest edition*, or CSA Standards

C22.1-94, Canadian Electrical Code, Part 1 and C22.2 No.0-M91 - latest edition** and all local

codes and ordinances. If codes permit and a separate ground wire is used,

it is recommended that a qualified electrician determine that the ground path is adequate.

Do not ground to a gas pipe. Check with a qualified electrician if you are not sure range hood is properly grounded. Do not have a fuse in the neutral or ground circuit.

IMPORTANT

Save Installation Instructions for electrical inspector's use.

The range hood must be connected with copper wire only.

The range hood should be connected directly to the fused disconnect (or circuit breaker) box through

metal electrical conduit.

Wire sizes must conform to the requirements of the

National Electrical Code ANSI/NFPA 70 -- latest edition*, or CSA Standards C22.1-94, Canadian

Electrical Code Part 1 and C22.2 No. 0-M91 - latest edition** and all local codes and ordinances.

A U.L- or C.S.A.-listed conduit connector must be

provided at each end of the power supply conduit (at the range hood and at the junction box).

iNSTALLING

For the most efficient air flow exhaust, use a straight run or as few elbows as possible.

CAUTION: Vent unit to outside of building, only.

One people isnecessary for installation. On avarage 2 hours are necessary to complete

installation (without considering cut to be done on wall and or on cabinet, installation of ducts,

conduit and electrical connections to the mains).

installation steps: 12 installationsteps are required for both

installationmethods

Wall mount installation steps or in alternative Cabinet installation

The hood is fitted with Screws and Drywall Anchors suitable for most surfaces, consult a

Qualified installer, check if they perfectly fit with your cabinet/wall.

Do not use flex ducting.

TH HOOD

• 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.

• Make up air: Local building codes may require the use of Make-Up Air Systems when using

Ducted Ventilation Systems greater than specified CFM of air movement. The specified CFM varies from locale to locale.

Consult your HVAC professional for specific

requirements in your area.

Typical installation

The height from the countertop to the bottom of the hood is 24" to 30".These hoods are not

recommended to be used over indoor grills.

1. Choose vent options The hood isdesigned ready to be used for vertical discharge as shown below. Note: see also Fig. 1-3-5 for Cabinet preparation.

If desired, the hood can be converted for horizontal discharge as shown below. Note: see also Fig. 2-3-5 for Cabinet and rear wall preparation.

DUCTING Provide a Round Duct having a diameter of 8"

see Figure 2 and Figure 3 for location on cabinet bottom.

install a 1/2" conduit from the service panel long enough to reach the hood once itis installed. Power supply must be rated for 120 V AC, 60

Hz. 15 or 20 A.

TABLE 2. DUCTWORK INSTALLATION GUiDELiNES

For safety reasons, ducting should vent directly outdoors (not into an attic, underneath the house, into the

garage or into any enclosed space).

Keep duct runs as short and straight as possible. Duct fittings (elbows and transitions) reduce air flow efficiency.

Back to back elbows and ,,S"turns give very poor delivery and are not recommended. A short straight length of duct at the inlet of the remote blower gives the best delivery. Transition to duct from the integral blower or remote duct transition as close to the downdraft as is pos-sible.

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

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.

• After having choosen the vent option:

1. Prepare duct and conduit cut outs, see Fig.1,2,3 as needed.

2. Discharge Direction: The hood isshipped ready for vertical discharge.

_i_ WARNING! Before installing remove the knock-out plate

that close the air outlet on the top if is desired to use the range hood for vertical discharge OR the rear outlet if is desired to use the range hood for horizontal discharge. (see also Figure 5).

WARNING!

Once the Knock out plate has been removed, this cannot be reinstalled anymore close the air outlet (see also Figure 5).

To change to horizontal discharge, do the following (see also Figure 4): a. Remove knock-out plate on the rear side of

the hood (see also Figure 5)

b. Remove and keep the 4 screws (2 per side)

that fix blower on top of the hood and release it from keyholes.

c. Rotate the blower 90° and check that pins on

side blower fixing brackets fit into the pre- installing holes.

d. Fix the blower on the rear side with the same

4 screws (see step b).

3. Assembly of the 8" Transition: The transition supplied with the hood mounts to the top or rear of the hood.

Note- Cabinet installation with vertical discharge ONLY: do not installtransition until

hood has been fixed on cabinet. a. Place the transition piece over the hood

exhaust and secure with 4 screws provided (Figure 5).

b. Duct tape connection between transition and

hood.

4. After the hood installation height has been determined draw a horizontal line at a

distance above the cooktop equal to the desired hood installation height plus 7- 11

2". See also Figure6a.

5. Find the centerline of the cooktop. Draw a vertical line along this centerline up to the horizontal line drawn in step 1 and draw a vertical line right and left at a distance of 12-5/8" to determine the mounting location of the mounting hooks shipped with the hood.

6. Fit two mounting hooks on the wall to hang the hood through the provided slots (2 wall anchors+2 hooks + 2 screws 5x35).

7. Run 8" Duct, long enough to reach the transition once the hood has been installed plus

1 1/2" inch to connect ductwork. Fix Duct to transition with screws and seal with

tape.

8. Remove 1 of 2 knockouts and install 1/2" conduit connector in j-box.

9. Hang the hood and adjust its position through the screws on the hooks.

lO.Fix the hood to 4 additional point,2 on upper

side, 2 on lower side (use 4 wall anchors + 4 washers + 4 screws 5x35.

Note: see above if wall mount installation is preferred

Note: distances on Table 3.

4. Find the centerline of the cabinet bottom. Draw a line along this centerline from rear to front of

the cabinet.

5. Draw two lines, one at a K distance from the wall, the other one at a Z distance from the

previous line. Mark 4 points, two along each line at a distance

of half W from the center line, to determine the screw locations.

6. Fit 4 screws on cabinet bottom do not tighten completely but leave a space of about 1/2" from

cabinet bottom surface and head screws.

7. Run 8" Duct, long enough to reach the transition once the hood has been installed plus

1 1/2" inch for connect ductwork.

8. Remove 1 of 2 knockouts and install 1/2" conduit connector in j-box.

9. Hang the hood on screws through side slots provided on hood top. Tighten the four screws. Note: If possible fix the hood on the wall at 4 additional point (2 on upper side, 2 on lower side).

lO.From the inside of the cabinet attach the

transition on upper outlet (vertical discharge - see also ,,Assembly of the 8" Transition" on previous pages)
