Installation Instructions

ADVANCE PLANNING

Ductwork Planning

•This hood may be vented vertically through upper cabinets, soffit or ceiling. A duct transition piece is supplied for vertical exhaust. Use locally supplied elbows to vent horizontally through the rear wall. See page 13.

•Determine the exact location of the vent hood.

•Use the shortest and straightest duct route possible. For satisfactory performance, duct run should not exceed 100 equivalent length for any duct configurations.

•Refer to “Duct Fittings” chart to compute the maximum permissible length for duct runs to the outdoors.

•Use metal ductwork only.

•A transition piece for 7” round duct is supplied. Use 7” round duct or you may use 3¼” x 12” rectangular.

•Install a wall cap or roof cap with damper at the exterior opening. Order the wall or roof cap and any transition needed in advance.

Kit - JXDW1

Order kit JXDW1 if your installation requires horizontal ducting from the top of the hood through the back wall and:

•You have an 8 ft. ceiling and need to use a JXCH Series Chimney Cover, or

•You have a 12” cabinet or 12” soffit that the hood is to be mounted beneath.

This kit provides a duct transition from 7” round to 3¼” x 10” rectangular for through-the-wall venting.

Wall Framing for Adequate Support

•This vent hood is heavy. Adequate structural support must be provided. The hood must be secured to vertical studs in the wall. See page 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.

DUCT FITTINGS

Follow these guidelines for proper duct sizing in the ducting charts.
