WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THIS FAN WITH ANY SOLID-STATE CONTROL DEVICE.
WARNING
TO REDUCE THE RISK OF FIRE ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a. Use this unit only in the manner intended by the manufacturer, if you have questions, contact the manufacturer.
b. Before servicing or cleaning unit, switch power off at service panel and lock panel to prevent power from being switched on accidentally.
When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service
panel.
CAUTION
For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors. Take care when using cleaning
agents or detergents. Suitable for use in household cooking area.
WARNING
TO REDUCE THE RISK OF RANGE TOP GREASE FIRE:
a. Never leave surface units unattended at high settings. Boilovers cause smoking and greasy spillovers that may ignite. Heat oils slowly
on low or medium settings.
b. Always turn hood ON when cooking at high heat or when flaming food
c. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
d. Use proper pan size. Always use cookware appropriate for the size of the surface element.
e. Keep fan, filters and grease laden surfaces clean.
f. Use high setting on hood only when necessary.
g. Don’t leave hood unattended when cooking.
h. Always use cookware and utensils appropriate for the type of and amount of food being prepared.
WARNING
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP FIRE, OBSERVE THE FOLLOWING:
a. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS.
If the flames do not go out immediately, EVACUATE AND CALL THE FIRE DEPARTMENT.
b. NEVER PICK UP A FLAMING PAN – You may be burned.
c. DO NOT USE WATER, including wet dishcloths or towels – a violent steam explosion will result.
d. Use an extinguisher ONLY if:
1. You know you have a Class ABC extinguisher, and you already know how to operate it.
2. The fire is small and contained in the area where it started.
3. The fire department is being called.
4. You can fight the fire with your back to an exit
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.
b. Sufficient air is needed for power 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
the local code authorities.
c. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
d. Ducted fans must always vent to the outdoors.
e. If this unit is to be installed over a tub or shower, it must be marked as appropriate for the application and be connected to a GFCL
(Ground Fault Interrupter protected branch circuit).
g. NEVER place a switch where it can be reached from a tub or shower.
h. Make sure the power is off before installing, wiring or maintenancing.

Important Safety Notice

CAUTION
To reduce risk of fire and to properly exhaust air outside - Do not vent exhaust air into spaces within walls, ceilings, attics,
crawl spaces or garages.
WARNING
TO REDUCE THE RISK OF SHOCK, THIS FAN MUST BE INSTALLED WITH AN ISOLATING WALL CONTROL/
SWITCH.
OPERATION
Always leave safety grills and filters in place. Without these components, operating blowers could catch onto hair, fingers
and loose clothing.
*NOTE: Please check www.zephyronline.com or call us for revisions before doing any custom work.
ELECTRICAL REQUIREMENTS
Important:
Observe all governing codes and ordinances.

latest edition* or CSA standards C22.1-94, Canadian Electrical Code, Part 1 and C22.2 No.0-M91 - latest edition** and
all local codes and ordinances.
If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the
ground path is adequate.
Do not ground to a gas pipe.
Check with a qualified electrician if you are not sure the range hood is properly grounded.
Do not have a fuse in the neutral or ground circuit.
*National Fire Protection Association Batterymarch Park, Quincy, Massachusetts 02269
** CSA International 8501 East Pleasant Valley Road, Cleveland, Ohio 44131-5575
This appliance requires a 120V 60Hz electrical supply and connected to an individual properly grounded branch circuit
protected by a 15 or 20 ampere circuit breaker or time delay fuse. Wiring must be 2 wire with ground. Please also refer to
Electrical Diagram on product.
A cable locking connector (not supplied) might also be required by local codes. Check with local requirements, purchase
and install appropriate connector if necessary.

Installation – Ducting Calculation Sheet

6
www.zephyronline.com
DUCTING
A minimum of 6” round or 3-1/4” x 10” rectangular
duct work must be used to maintain maximum air
flow efficiency with the 600 cfm internal blower.
A minimum of 10” to 8” round duct work must be
used with the 1000 cfm external blower.
Always use rigid type metal ducts only. Flexible
ducts could restrict air flow by up to 50%.
Use calculation (on page 5) to compute total
available duct run when using elbows, transitions
and caps.
ALWAYS, when possible, reduce the number or
transitions and turns. If long duct run is required,
increase duct size from 6” to 7 or 8”. If a reducer is
used, install a long reducer instead of a pancake
reducer. Reduce duct size as far away from
opening as possible.
If turns or transitions are required; install as far
away from opening and as far apart, between 2,
as possible.
Minimum mount height between range top and
hood bottom should be no less than 24”.
Maximum mount height should be no higher than
32”.
It is important to install the hood at the proper
mounting height. Hoods mounted too low could
result in heat damage and fire hazard; while hoods
mounted too high will be hard to reach and will
lose its performance and efficiency.
If available, also refer to range manufacturer’s
height clearance requirements and recommended
hood mounting height above range.
Vertical Ducting:
6” round minimum (internal blower)
10” to 8” round minimum (external blower)
Horizontal Ducting:
3-1/4”x10” minimum (internal blower)
No horizontal option available for external blower
DAMAGE-SHIPMENT / INSTALLATION:
• Please fully inspect unit for damage before
installation.
• If the unit is damaged in shipment, return the
unit to the store in which it was bought for
repair or replacement.
• If the unit is damaged by the customer, repair
or replacement is the responsibility of the
customer.
• If the unit is damaged by the installer (if other
than the customer), repair of replacement must
be made by arrangement between customer
and installer.

WARNING FIRE HAZARD
NEVER exhaust air or terminate duct work into spaces between walls, crawl spaces, ceiling, attics or garages.
All exhaust must be ducted to the outside.
Use metal ductwork only.
Fasten all connections with sheet metal screws and tape all joints with certified Silver Tape or Duct Tape.
