Safety Information

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

• Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction.
• Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back-drafting. Follow the heating equipment manufacturer's guidelines and safety standards, such as those published by the National Fire Protection Association (NFPA), the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) and the local code authorities. When applicable, install any makeup (replacement) air system in accordance with local building code requirements. Visit GEAppliances.com for available makeup air solutions.
• When cutting or drilling into walls or ceilings, do not damage electrical wiring and other hidden utilities.
• Ducted systems must always be vented to the outdoors.
• Local codes vary. Installation of electrical connections and grounding must comply with applicable codes. In the absence of local codes, the vent should be installed in accordance with National Electrical Code ANSI/NFPA 70-1990 or latest edition.

CAUTION: To reduce risk of fire and to properly exhaust air, be sure to duct air outside—do not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces or garages.

PRODUCT DIMENSIONS AND CLEARANCES

The vent hood must be installed 24" minimum, and 30" maximum above the cooking surface.

NOTE: Installation height should be measured from the cooking surface to the lowest part of the hood.

Diagram Description: A diagram shows a vent hood mounted above a cooking surface. It indicates minimum and maximum installation heights relative to the cooking surface. For electric ranges, the minimum height is 24 inches and the maximum is 30 inches. For gas ranges, the minimum height is 30 inches and the maximum is 36 inches. The diagram also shows a measurement from the bottom of the hood to the ceiling, indicating the need for duct covers for higher ceilings.

PX8DC1SWSS Duct Cover Accessory: This accessory is available for installations with ceiling heights above 9' to 10' and higher. See the table on page 8. The duct cover accessory must be on-site with the hood at the time of installation.

Installation Preparation

DUCTWORK PLANNING

• This hood is designed to be vented vertically through the ceiling. Use locally supplied elbows to vent horizontally through the rear wall.
• Determine the exact location of the vent hood.
• Plan the route for venting exhaust to the outdoors.
• Use the shortest and straightest duct route possible. For satisfactory performance, duct run should not exceed 10' equivalent length for any duct configurations.
• Refer to "Duct Fittings” chart to compute the maximum permissible length for duct runs to the outdoors.
• Use rigid metal ductwork only.
• This vent hood must use a 8" round duct.
• Install the house duct to run horizontally between ceiling joists or straight up through the roof.
• Install a wall or roof cap with damper at the exterior opening. Order the wall or roof cap and any transition and length of duct needed in advance.
• When applicable, install any makeup (replacement) air system in accordance with local building code requirements. Visit GEAppliances.com for available makeup air solutions.

WARNING: TO REDUCE THE RISK OF FIRE, USE ONLY RIGID METAL DUCTWORK.

WALL FRAMING FOR ADEQUATE SUPPORT

• This vent hood is heavy. Adequate structural support must be provided. The hood must be secured to a vertical stud in the wall. See page 9 or 14.
• We strongly recommend that the vent hood with duct cover be on site before final framing and wall finishing. This will also help to accurately locate the ductwork and electrical service.
• Installation will be easier if the vent hood is installed before the cooktop and countertop are installed.

ADVANCE PLANNING

A duct cover accessory may be required for your hood installation depending on ceiling height.
