applicable codes and standards, including fire-rated construction.
2) When cutting or drilling into wall or ceiling, be careful not to damage electrical wiring or other hidden
utilities.
3) Ducted fans must be vented to the outside.
a) Before servicing or cleaning unit, open the light panel and SWITCH POWER OFF AT SERVICE
PANEL.
b) Clean all grease laden surfaces frequently. To reduce the risk of fire and to disperse air
properly, make sure to vent air outside. DO NOT vent exhaust air into wall spaces, attics, crawl
spaces or garages.
NOTE - This warranty is invalid without an authorized agent’s receipt or if unit is
damaged due to misuse, poor installation, improper use, mistreatment,
negligence or any other circumstances beyond the control of KOBE
RANGE HOODS authorized agents. Any repair carried out without the
supervision of KOBE RANGE HOODS authorized agents will
automatically void the warranty.
- KOBE RANGE HOODS will not be held responsible for any damages to
personal property or real estate or any bodily injuries whether caused
directly or indirectly by the range hood.
WARNING : TO REDUCE THE RISK OF PERSONAL INJURY IN THE EVENT OF A RANGE
TOP GREASE FIRE:
- Keep all fan, baffle/spacer/filter/oil tunnel/oil container and grease-laden surfaces clean. Grease
should not be allowed to accumulate on fan, baffle/spacer/filter/oil tunnel/oil container.

What to Do In The Event Of a Range Top Grease Fire
• SMOTHER FLAMES with a tight fitting lid, cookie sheet, or metal tray, and then turn off the burner.
KEEP FLAMMABLE OR COMBUSTIBLE MATERIAL AWAY FROM FLAMES. If the flames do not
go out immediately, EVACUATE THE AREA AND CALL THE FIRE DEPARTMENT or 911.
• NEVER PICK UP A BURNING PAN – You May Get Burned.
• DO NOT USE WATER, including wet dishcloths or towels – a violent steam blast will result.
• Use an extinguisher ONLY if:
a) You have a Class A, B, C extinguisher and know how to operate it.
b) The fire is small and contained in the area where it started.
c) The fire department has been called.
d) You can fight the fire with your back to an exit.
What to Do If You Smell Gas
- Extinguish any open flame.
- Do not try to turn on the lights or any type of appliance.
- Open all doors and windows to disperse the gas. If you still smell gas, call the Gas Company and
Fire Department right away.
CAUTION
1) For general ventilation use only. Do not use to exhaust hazardous or explosive materials and
vapors.
2) To reduce the risk of fire, use only metal ductwork. Sufficient air is needed for proper combustion
and exhausting of gases through the flue (chimney) to prevent back drafting.
3) 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 code authorities.
4) Activating any switch on may cause ignition or an explosion.
5) Due to the size and weight of this hood, two people installation is recommended.
ELECTRICAL SHOCK HAZARD
–
Can result in serious injury or
death. Disconnect appliance from electric power before servicing.

Preparation Before Installation
NOTE: TO AVOID DAMAGE TO YOUR HOOD, PREVENT
DEBRIS FROM ENTERING THE VENT OPENING.
• Decide the location of the venting pipe from the hood to
the outside. Refer to Figure 1.
• A straight, short vent run will allow the hood to perform
more efficiently.
• Try to avoid as many transitions, elbows, and long run
as possible. This may reduce the performance of the
hood.
• Temporarily wire the hood to test for proper operation
before installing.
• Important: Peel protective film off the hood, if any.
• Use duct tape to seal joints between pipe sections.
CAUTION : If moving the cooking range is
necessary to install the hood, turn off the power in an
electric range at the main electrical box. SHUT OFF
THE GAS BEFORE MOVING A GAS RANGE. And use a
protective covering to protect cooktop and/or
countertop from damage.
