BEFORE YOU BEGIN

Read these instructions completely and carefully.

•IMPORTANT – Save these instructions for local inspector’s use.

•IMPORTANT – Observe all governing codes and ordinances.

•Note to Installer – Be sure to leave these instructions with the Consumer.

•Note to Consumer – Keep these instructions for future reference.

•Skill level – Installation of this appliance requires basic mechanical and electrical skills.

•Completion time – 30 minutes–3 hours

•Proper installation is the responsibility of the installer.

•Product failure due to improper installation is not covered under the Warranty.

FOR YOUR SAFETY:

WARNING – Before beginning the installation, switch power off at service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

OPTIONAL POWER CORD KIT JXHC1

An optional Power Cord Connection Kit, model JXHC1, is available at extra cost from your GE supplier for installation using a standard 3-prong, grounded wall outlet . Follow the Installation Instructions packed with the kit to connect the power cord to the range hood.

DUCTWORK REQUIREMENTS

NOTE: Read the ductwork sections only if you do not have existing ductwork. If you have existing ductwork, skip to the “Damage” section and proceed.

The venting system must exhaust to the outside.

This hood can be vented vertically through upper cabinets or horizontally through an outside wall. Ductwork is not included.

Exhaust connection:

The hood exhaust has been designed to mate with standard 31⁄ 4″ x 10″ rectangular ducting or 7″ diameter round ducting.

If a 6″ round duct is required, a rectangular-to-round transition adaptor must be used*. Do not use less than a 6″ diameter duct.

Maximum duct length:

For satisfactory air movement, the total duct length of a 31⁄ 4″ x 10″ rectangular, 6″ or 7″ diameter round duct should not exceed 65 equivalent feet. See the

WORKSHEET–CALCULATE TOTAL EQUIVALENT DUCTWORK LENGTH section.

NOTE: It is important that ducting be installed using

the most direct route and with as few elbows as possible. This ensures clear venting of exhaust and helps prevent blockages. Also, make sure dampers swing freely and nothing is blocking the ducts.

Elbows, transitions, wall and roofcaps, etc.,

present additional resistance to airflow and are equivalent to a section of straight duct longer than their actual physical size. When calculating the total duct length, add the equivalent lengths of all transitions and adaptors plus the length of all straight duct sections. The charts on the following pages show you how to calculate total equivalent ductwork length using the approximate feet of equivalent length of some typical ducts.

*IMPORTANT: If a rectangular-to-round transition adaptor is used, the bottom corners of the damper will have to be cut to fit, using the tin snips, in order to allow free movement of the damper. Equivalent lengths of duct pieces are based on actual tests and reflect requirements for good venting performance with any hood.
