PREPARING THE HOOD
1. Unpack hood and check contents. You should receive:
1 – Filter with built-in light lens
1 – 3-1/4" x 10" damper/duct connector
1 – Installation parts bag, located inside junction box

FILTER
2. Remove junction box cover, EZ1 brackets and parts bag from inside
junction box.
3. Remove top or rear electrical knockout. Install an appropriate strain
relief.
4. Select one of the three types of venting available:
Non-Vented — Remove vent
cover from hood front. Replace
the aluminum filter with a non-
ducted filter (BP57 or R610050
- purchase separately). Go
to "Preparing the Installation
Location".
Rectangular Vented — 3-1/4" x 10" vertical or horizontal. Remove
knockout
for vertical or knockout
damper/duct connector over opening. Go to "Planning Ductwork
Installation".
Round Vented — 7" vertical. Remove knockouts
duct collar. Go to "Planning Ductwork Installation".
PLANNING DUCTWORK
INSTALLATION
This section is for vented hoods only. For non-vented hoods, skip
this section and go to "Preparing the Installation Location".
Begin planning ductwork by deciding where duct will run between hood
and outside. For best performance, use shortest possible duct run and a

minimum number of elbows. There are several choices.
Ducting directly through the wall (for range hoods mounted on an
exterior wall). Shown are two ways to duct through an outside wall. If a
wall cap is used directly off the back of the hood, special care must be
taken to make sure that the damper in the damper/duct connector on
the hood and damper in the wall cap do not interfere with each other
when the hood is operating. This could result in either inadequate air
delivery or back drafts. If this condition does exist, remove the hood
damper flap. Sometimes when using a wall cap, it is easier to duct
vertically and then use an elbow.
Ducting straight up through roof using 3-1/4" x 10" or 7" round duct.
For single story installations.
Ducting between ceiling joists for multi-story installations or through
soffits above cabinets where soffit connects to outside walls.
INSTALLING THE DUCTWORK
THESE INSTRUCTIONS ARE FOR VENTED HOODS ONLY. FOR NON-
VENTED HOODS, SKIP THIS SECTION AND GO TO "INSTALLING
THE RANGE HOOD".
START AT THE EXTERIOR AND RUN DUCTWORK BACK TO THE
RANGE HOOD.
FOR BEST PERFORMANCE OF YOUR RANGE HOOD, USE THE
SHORTEST POSSIBLE DUCT RUN AND A MINIMUM NUMBER OF
ELBOWS.
NEVER VENT A RANGE HOOD INTO AN ATTIC SPACE BECAUSE A
BUILDUP OF GREASE WILL BECOME A FIRE HAZARD.
USE ONLY METAL DUCTWORK (DO NOT USE PLASTIC DUCT).
ASSEMBLE SECURELY SO THAT IN CASE OF A GREASE FIRE
exposing
ON THE RANGE, THE FIRE WILL BE CONTAINED INSIDE METAL
DUCTWORK.
IT IS A GOOD PRACTICE TO TAPE ALL DUCT CONNECTIONS,
MAKING THEM BOTH SECURE AND AIR TIGHT.
1. Follow appropriate directions below for type of ductwork you are
installing.
Wall Cap Discharge: Use saber saw or keyhole saw to cut hole slightly
larger than duct size used so that duct will line up easily with damper/duct
connector on hood. Install casing strips if cap will be installed on siding.
Attach required amount of duct to wall cap and run duct back to hood.
Fasten cap to wall and caulk well. Make sure that enough duct runs into
the room so that the duct will overlap the damper/duct connector when
the hood is installed.
