• Two peopleare necessary for installation. On average 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).

• 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 location to location

Consult your HVAC professional for specific requirements in your area.

Typical installation

The height from the countertop to the bottom of the hood is 30" to 36". These hoods are not recommended to be used over indoor grills.

1. Choose vent options

The hood is designed to be used for vertical discharge as shown below.

Note: see also Fig. 1-2-3 for Cabinet preparation.

Install a 1/2" conduit from the service panel long enough to reach the hood once it is installed. Power supply must be rated for 120 VAC, 60Hz. 15 or 20A.

DUCT FITTINGS

Use this chart to compute maximum permissable lengths for duct runs to

outdoors.

Note: Do not exceed maximum permissable

equivalent lengths!

Maximum recommended duct

length for these hoods: 150 feet

Flexible ducting: If flexible metal ducting is used, all

the equivalent feet values in the table should be doubled. The flexible

metal duct should be straight and

smooth and extended as much as

possible.

Do NOT use flexible plastic ducting.

Note: Any home ventilation system, such as a ventilation hood, may interrupt the proper flow of combustion air and exhaust required by fireplaces, gas furnaces, gas water heaters and other naturally

vented systems. To minimize the chance of interruption of such naturally vented systems, follow the heating

equipment manufacturer's guidelines and safety standards such as those published by NFPA and ASHRAE.

*Hoods are supplied with a 10"

round transition. A locally supplied transition is required

for other sizes.

Note: Outlet on top of hood is 8-1/8" x 8".

TotalDuct Run

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 to remote duct transition as close as possible.

In order opreference, 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.

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

fixed on cabinet or wall.

a. Place the transition piece over the hood

b. Wrap all joints (metal transition and hood)

with duct tape for an airtight seal.

c. Remove tape holding damper.

Note: see below if cabinet installation ispreferred

3. 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- 1/2". See also Figure 4a.

4. Find the centerline of the cooktop. Draw a vertical line along this centerline up to the hori- zontal line drawn in step 1 and draw a vertical

line right and left at a distance of12-5/8" to

determine the mounting location of the

mounting hooks shipped with the hood.

5. Fit two mounting hooks on the wall to hang the

hood through the provided slots (2 wall

anchors + 2 hooks + 2 screws 5x35).

6. Run 10" 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 withtape.

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

8. Hang the hood and adjust its position through

the screws on the hooks.

9. Fix the hood to 4 additional point, 2 on

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