WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK,
OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
A. Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable codes and
standards, including fire-rated construction. Switch power off at
service panel and lock the service disconnecting means to
prevent power from being switched on accidentally during
installation.
B. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
C. Ducted fans must always be vented to the outdoors.
D. 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 guideline and safety standards such as those
published by the National Fire Protection Association (NFPA), and
the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and local code authorities.

Ducting Do's and Don'ts
NEVER restrict the duct size. The single blower unit (B100) requires 6" round duct or
equivalent (28 square inches), and the dual blower unit (B200) requires 8" round duct or
equivalent (50 square inches). When combining ducts together, the square inch area must
reflect the total square inch area of the ducts being combined. Using
Vent-A-Hood transitions (back page) will ensure proper efficiency.

Do not use flexible or corrugated duct. This type of duct will restrict air flow and reduce
performance. Only use smooth galvanized metal duct. Observe local codes regarding
special duct requirements and placement of duct against combustibles. Make the duct run
as short and as straight as possible with as few turns as possible. Avoid sharp angled
turns. Instead, use smooth gradual turns such as adjustable elbows or 45 degree angled
turns. For duct runs over 20 feet, increase duct diameter by one inch for every ten feet of
duct. A 90 degree elbow is equivalent to 5 feet of duct. Using Vent-A-Hood roof jacks or
wall louvers (back page) will ensure proper efficiency. Air must not be restricted at the end
of duct run. Do not use screen wire or spring loaded doors on wall louvers or roof jacks.
Do not terminate vent into an attic or chimney. Where possible, seal joints with duct tape.
The hood must be ducted unrestricted to the outdoors.

Select an installation method. Method 1 allows the hood and duct cover to be installed together as a single unit.
The final duct connection is made at the ceiling as the hood is attached to the wall. Method 2 allows the duct
cover to be slid into place after the hood is attached to the wall. Caution must be taken when using this method
to prevent scratching the top of the hood or the ceiling.
IF THE HOOD IS TO BE "BACK VENTED", PROCEED DIRECTLY TO STEP 5.
Consult the connection diagrams (on next page) for further details on exhaust outlet placement.
Method 1: Pre.install the duct from the outside of the home to the ceiling over the exhaust outlet of the
hood. The end of the duct should extend 1" below the ceiling.
Method 2: Pre-install the duct from the outside of the home down to the location of the exhaust outlet
on the top of the hood allowing room for the transition (if applicable). If a transition is used,
install duct down to the location of the transition outlet plus 1". This will allow the transition to
engage 1" inside of duct.
Use duct tape to seal all joints. A complete listing of available Vent-A-Hood ducting materials is provided on the
back page of this instruction sheet.
Transition heights are as follows:
Single Blower (B100) :

QNote: Add .5 amp for each halogen bulb. Equivalent CFM refers to the fact that the Magic Lung blower uses centrifugal filtration units,
whereas others use conventional filters. Apply this guideline when comparing blower units made by other manufacturers.
Remove the duct cover from its packaging. Place the duct cover over the top of the hood taking care to align
the single flange on top of the hood between the double flange on the bottom of the duct cover. Press the duct
cover down to engage the flanges. Lift the hood and hold in place on the wall in the location where it will be
installed. Lightly mark the wall with a short horizontal mark along the bottom edge of the hood.
Measure on the wall 9" above the mark made in Step 9 and lightly mark the wall with a level horizontal line.
Measure where the center (left to right) of the hood will be and mark the horizontal line on the wall with a
short vertical centerline.
Remove the screws inside the top of the back of the hood that retain the wood strip recessed in the mounting
channel. Note: Some retaining screws may be located behind the blower(s). Remove the wood mounting strip
from the back of the hood and place the top edge of the strip 1/8" below and parallel to the level horizontal
mark on the wall. Referencing the vertical centerline in Step 10, place the mounting strip so it is centered on
the wall in the space where the hood will be (left to right). Using proper hardware, attach the mounting strip
to at least two wall studs. Drill pilot holes in the strip to prevent splitting.
FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY TO STEP 13.
Note: Wall studs may interfere with back venting installations. Additional framing may be required. It is
necessary to cut duct access hole(s) in the wall prior to installing the hood. To accomplish this, first remove and
set aside the duct cover that was previously installed in Step 9. Hold the hood on the mounting strip by aligning
the channel at the top of the back of the hood over the wood mounting strip on the wall. Place the appropriate
elbow(s) on top of the hood in line with the hood exhaust collar(s). On the wall, trace around the elbow(s).
Remove the hood and elbow(s) from the wall. Cut around the outside of the traced line(s), avoiding wall studs.
Install the duct from the outside of the home to the opening in the wall. Use duct tape to seal joints.
Note: If using Method 1, place the duct cover back onto the top of the hood.
Hang the hood on the mounting strip by aligning the channel at the top of the back of the hood over the wood
mounting strip on the wall. While holding the hood in place, mark locations on the mounting strip through the
two mounting holes in the channel at the top of the hood. Some mounting holes may be located behind the
blower(s). Remove the hood and drill 3/32" pilot holes at the center of the marks in the wood strip to prevent
splitting.
FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE NOT BACK VENTING, PROCEED DIRECTLY TO STEP 15.
Place the appropriate elbow(s) on the top of the hood. Elbow(s) should be placed inside the collar(s) of the
exhaust outlet(s). Use duct tape to seal joints.

(Continued) FOR BACK VENTING APPLICATIONS ONLY. IF YOU ARE NOT BACK VENTING, PROCEED TO STEP 15.
Method 1: Insert the electrical wire from the service panel through the electrical wire clamp on each
motor box. Tighten the wire clamp(s). Lift the hood up to the wall and hang it on the mounting
strip, taking care to properly align the duct connection between the hood and the wall.
Method 2: Lift the hood up to the wall and hang the hood on the mounting strip, taking care to properly
align the duct connection between the hood and the duct in the wall.
Secure the hood to the mounting strip by installing the screws (removed from the strip in Step 10) into the pilot
holes drilled in Step 12.
Method t: Secure the slack in the electrical wire.
Method 2: Insert the electrical wire from the service panel through the electrical wire clamp on each motor
box. Tighten the wire clamp(s). Slide the duct cover between the ceiling and the top of the
hood while aligning the flange on top of the hood between the double flange on the bottom of
the duct cover. Gently slide the duct cover to the wall. Caution must be taken to avoid
scratching the hood or ceiling.
SKIP STEP 15. PROCEED DIRECTLY TO STEP 16.
15) If applicable, install transition inside the exhaust collars and seal with duct tape.
Method 1: Insert the electrical wire from the service panel through the electrical wire clamp on each
motor box. Tighten the wire clamp(s). Cut a piece of duct the length of the duct cover allowing
room for transition on the top of the hood (if applicable). If a transition is used, cut the duct to
reach the transition outlet plus 1". This will allow the transition to engage 1" inside of the duct,
See Page 3 for transition height. One end of the duct must be crimped to fit inside the duct in
the ceiling. Insert non-crimped end over the transition or into the exhaust collar on the top of
the hood and seal with duct tape. Lift the hood into position while aligning the duct connection
between the hood and the duct in the ceiling.
Method 2: Lift the hood up to the wall and hang the hood on the mounting strip, taking care to properly
align duct work or transitions. Duct work and transitions must fit inside the exhaust collar. Use
duct tape to seal all joints.
Secure the hood to the mounting strip by installing the screws (removed from the strip in Step 10) into the pilot
holes drilled in Step 12.
Method 1: Secure the slack in the electrical wire.
Method 2: Insert the electrical wire from the service panel through the electrical wire clamp on each
motor box. Tighten the wire clamp(s). Slide the duct cover between the ceiling and the top
of the hood while aligning the flange on top of the hood between the double flange on the
bottom of the duct cover. Gently slide the duct cover to the wall. Caution must be taken to
avoid scratching the hood or ceiling.
