Installation Preparation - GE PVW1030 Installation Instructions Manual

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 150' 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.

Installation Preparation

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.
