Before Beginning Installation

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.
WARNING - TO REDUCE THE RISK OF FIRE, USE ONLY METAL

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.

Vent-A-Hood Transition
N/A
VP562 (Optional)

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.

Remove the hood from the packaging and place the back of the hood on the floor or countertop
wall where it will hang.

5)

Remove the blower shield(s) (A) by loosening the two brass screws on the bottom of the shield. Gently close the
back draft dampers from the top side of the hood. To remove the blower housing(s), un-snap the suitcase
latches (B) (one on each side of the housing). The housing(s) should be pulled forward and gently "tipped" to
clear the blower wheels and then out of the hood.

Remove the duct cover from its packaging. Remove and save the screws from the bottom of the duct cover.
Place the duct cover into the top of the hood. Attach the duct cover to the hood with the screws previously
removed. 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.

9)

Measure on the wall 9" above the mark made in Step 8 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.

10)

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 on the upper horizontal line on the wall.
Referencing the vertical centerline in Step 9, 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.

11)

FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY TO STEP 12.
Note: Wall studs may interfere with back venting installations. Additional framing may be required.
It is necessary to cut a duct access hole 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 8. 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.
Place the duct cover back into the top of the hood and reattach to the hood.

12)

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 hood and drill 3132" pilot holes at the center of marks in the wood strip to prevent splitting.

13)

FOR BACK VENTING APPLICATIONS ONLY. IF NOT BACK VENTING, PROCEED DIRECTLY TO STEP 14.
Place the appropriate back vent 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 joint(s).
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 into position while taking care to align the duct connection between the hood and 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. Secure the slack in the electrical wire.
SKIP STEPS 14AND 15. PROCEED DIRECTLYTO

STEP 16.

14)

If applicable, install transition inside the exhaust collars and seal with duct tape. Insert the electrical wire from
the service panel through the electrical wire clamp(s) on each motor box. Tighten the wire clamp(s). Cut a
piece of duct the length of the duct cover allowing room for the 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 heights. 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 top of the hood and
seal with duct tape.

15)

Lift the hood into position while aligning the duct connection between the hood and the duct in the ceiling.
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. Secure the slack in the electrical wire.

16)

Using UL listed wire nuts, attach the "neutral" wire(s) to the white lead(s), the "hot"
and the ground wire(s) to the green lead(s) inside the motor box(es).
