Read All Instructions Thoroughly 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 firerated 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.
E. ASHRAE residential ventilation standard 62.2 limits exhaust fans (total) to
a maximum of 15 CFM per 100 square feet of occupiable space, unless a
back drafting test is performed or make-up air is provided. Consult a local
HVAC engineer for make-up air evaluation.

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 airflow 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 the duct diameter by one inch for every ten feet of duct. A 90 degree
elbow is equal to 5 feet of duct. Using Vent-A-Hood roof jacks or wall louvers (back page) will
ensure proper efficiency. Airflow must not be restricted at the end of the duct run. Do not use
screen wire or spring-loaded doors on wall louvers or roof jacks. Do not terminate venting into
an attic or chimney. Where possible, seal joints with duct tape. The hood must be ducted to the
outdoors without restrictions.

Installation Details
1) Read all instructions thoroughly before beginning installation.
2) When installing a ZTH wall mount hood, it is recommended that the bottom edge of the hood be located no more than 30”
above the cooking surface. Exceeding the recommended maximum mounting height may compromise performance.
Shown with duct cover installed (sold separately).
3) IF THE HOOD IS TO BE “BACK VENTED”, PROCEED DIRECTLY TO STEP 4.
Install the duct(s) from the outside of the home to the ceiling over the exhaust outlet(s) of the hood. The end of the
duct should extend 1” below the ceiling. Consult the connection diagrams (below) for further details on exhaust outlet
placement.
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:
Dual Blower (B200):
8” round duct will connect directly to the exhaust outlet of the hood.
Single and Dual Blower (B100 & B200):
6” round duct will connect directly to the exhaust outlet of the hood;
8” round duct will connect directly to the exhaust outlet of the hood.
Optional 10” round combination transition (VP562, sold separately) is
17 1/2” tall.

4) Remove the hood from its packaging and place the back of the hood on the floor or countertop in front of the wall
where it will hang.
5) Remove the shipping tape that is securing the E-Z Clean shield(s) inside the hood. Remove the E-Z Clean shield(s) by
lightly pulling it toward the front of the hood. Gently close the back draft damper(s) from the top side of the hood. To
remove the blower housing(s), unsnap the suitcase latches (one on each side of the housing). The housing(s) should
be pulled forward and gently “tipped” to clear the blower wheel(s) and then out of the hood.
6) Remove the three screws retaining the blower motor(s). Unplug
and remove the motor(s), taking care not to damage the blower
wheel(s). It is not necessary to remove the blower wheel from
the motor.
Warning: Make sure power is off and locked at the service disconnecting
means on the service panel during installation.
7) Install an appropriate 1/2” UL listed electrical wire clamp through each motor box electrical opening on top of the hood.
Install electrical wiring from the service panel to the hood location for each motor box. Consult the connection diagrams
(on previous page) for further details on electrical placement. Extend wire to the hood. Electrical connection(s) will
occur before the hood is installed on the wall.

• Because the Magic Lung® blower uses centrifugal filtration rather than conventional baffle or mesh filters, the Magic Lung® blower can handle cooking equipment with higher cubic feet per minute (CFM) requirements and can deliver equivalent CFM much more
efficiently than other than other filtration systems. When comparing the Magic Lung® with other blower units made by other manufacturers, use the “Equivalent CFM”.

8) Remove the duct cover from its packaging. Remove and save the screws from the base of the duct cover. Place the
duct cover into the top of the hood and secure it temporarily to the hood with the screws previously removed. Lift the
hood and duct cover assembly and hold it 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) Remove the hood and duct cover assembly from the wall. On the back side of the hood, measure the distance between
the bottom edge of the hood and the top edge of the wood mounting strip. Measure this distance above the horizontal
line 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 upper 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 that is recessed in the mounting
channel. Note: Some retaining screws may be located behind the blowers. Remove the wood mounting strip from the
back of the hood and place the top edge of the strip on the upper, level, horizontal line on the wall. Referencing the
vertical centerline from Step 9, place the mounting strip so it is centered (left to right) on the wall in the space where
the hood will be located. Drill pilot holes in the strip to prevent splitting. Using proper hardware, attach the mounting
strip to at least two wall studs.

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 blowers. Remove hood
and drill 3/32” 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 elbow(s) on the top of the hood. Elbow(s) should be placed with the non-crimped end(s) on the
inside the collar(s) of the exhaust outlet(s). Use duct tape to seal joint(s).
Insert the electrical wire from the service panel into the electrical wire clamp on each motor box. Tighten the wire
clamp(s).
While securing the slack in the wire(s), lift the hood up to the wall and hang the hood on the mounting strip, taking
care to properly align the duct connection(s) between the elbow(s) on the hood and the duct(s) in the wall. Secure the
hood to the mounting strip by installing the screws (previously removed in Step 10) into the pilot holes drilled in Step
12. SKIP STEPS 14 AND 15. PROCEED DIRECTLY TO STEP 16.
14) If applicable, install transition inside the exhaust collars and seal with duct tape. Insert the electrical wire(s) from the
service panel into the electrical wire clamp(s) on each motor box. Tighten the wire clamp(s). Cut a piece of duct for each
outlet of sufficient length to meet the duct(s) in the ceiling allowing room for the transition (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 the
non-crimped end over the transition or into the exhaust collar(s) on top of the hood and seal with duct tape.
15) While securing the slack in the wire(s), lift the hood up to the wall and hang the hood on the mounting strip, taking
care to properly align the duct connection(s) between the hood and the duct(s) in the ceiling. Secure the hood to the
mounting strip by installing the screws (previously removed in Step 10) into the pilot holes drilled in Step 12.
16) From inside the hood, using UL listed wire nuts, attach the “neutral” wire(s) to the white lead(s), the “hot” wire(s) to
the black lead(s), and the ground wire(s) to the green lead(s) inside the motor box(es).
Warning: Do not operate hood without proper ground connection.
17) Plug the motors into the hood and reinstall the blower motors using the three retaining screws that were previously
removed in Step 6.
18) Replace the blower housing(s) and the blower shield(s). Make sure that the dampers open and close smoothly.
19) Refer to the Owner Maintenance Guide Operating Instructions for proper hood operation. Test all blower and light
functions to ensure they are operating properly.
