INSTALLINGTHE COOKTOP

NOTE: If the cooktop is installed in a 36" base

cabinet, the mounting brackets cannot be used

because of the interference with the sides of the cabinet. In this case, the cooktop can be secured to the sides of the cabinet using angle brackets

(not supplied). Remove one screw at the bottom of the cooktop body, on each side, then replace to hold the bracket to the cooktop. Then secure

the brackets to the cabinet sides with the screws provided.

Connect the 9-pin plastic plug from the downdraft unit to the 9-pin plastic socket situated adjacent to the power cord on the cooktop. Secure the metal cover in position over the connection.

GASCONNECTION

Install the supplied pressure regulator and nipple in the gas line as close to the cooktop inlet

as possible, making allowances for

ventilation ducting as necessary.

Make sure the regulator is

installed in the right direction. Install a manual shut-off valve in

the gas line in an easily accessible location, as close to the pipe stub

as possible, making allowances for

the ventilation ducting. Be sure you know how and where to shut off the gas supply to the cooktop.

NOTE: Instead of using solid piping to connect to pressure regulator, an approved flexible

metal appliance connector may be used between the pipe stub and shut-off and the pressure

regulator, if local codes permit.

Appropriate flare union adapters are required at each end of the flexible connector.

Turn on the gas; check for leaks using a liquid leak detector at all joints in the system (the pressure

test nipple is adjacent to the gas inlet pipe on the rear right hand side of the cooktop bottom).

CAUTION: DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.

IMPORTANT-- Disconnect the cooktop and the individual shut-off valve from the gas supply

piping system during any pressure testing of that

system at test pressures greater than 1/2 psig. Isolate the cooktop from the gas supply piping system by dosing the individual manual shut-off

valve to the cooktop during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig.

INSTALLTHE DUCTWORK

Use minimum 26 gauge galvanized or 24 gauge aluminum duct in 6" round or 31/4"x 10" size, or a combination of both. PVC duct should be used

if installing under a poured concrete slab. DO NOT use flexible ducting.

Always use an

appropriate roof or wall cap with damper. Laundry

type wall caps should never be

used. Use the

straightest duct run possible.

For satisfactory

performance the duct run should not exceed

75 ft. or its equivalent length if bends or other various fittings are used. Refer to table of equivalent lengths for various duct configurations.

Install ductwork so that the piece of duct nearest the downdraft unit slots INTO the next piece of duct. Secure all joints with self tapping screws and apply duct tape around the joint to ensure an airtight seal.
