IMPORTANT SAFETY INSTRUCTIONS
- PLEASE READ THIS SECTION CAREFULLY BEFORE INSTALLATION -
WARNING : TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR PERSONAL INJURY,
OBSERVE THE FOLLOWING:
1) Installation and electrical wiring must be done by qualified professionals and in accordance with all
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 void 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

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 MATERIALAWAY FROM FLAMES. If the flames do not go
out immediately, EVACUATE THE AREAAND CALLTHE FIRE DEPARTMENT or 911.
• NEVER PICK UP A BURNING PAN – You May Get Burned.
• DO NOT USE WATER, including wet dishcloths or towels – a steam blast will result.
• Use an extinguisher ONLY if:
a) You have a ClassA, 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 thosepublished
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, installation by 2 persons is recommended.

Disconnect appliance from electric power before servicing. If equipped,
the fluorescent light bulb contains small amounts of mercury, which must

Preparation before Installation
NOTE: TO AVOID DAMAGE TO YOUR HOOD,
PREVENT DEBRIS FROM ENTERING
THE VENT OPENING.
- Decide the location of the vening pipe from the
hood to the outside. (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. If the hood does not
operate, check the circuit breaker or house fuse.
If the hood is still not working, disconnect power
supply and check the continuity of all wire
connections.
- Peel protective film off the hood (if any).
- Use duct tape to seal joints between pipe
sections.
- For installing under the cabinet with recessed
bottom, attach 4-inch wide wood filter strips (not
included) on each side (Figure 2)
- Using reference on Page 19-20 to measure and
create access opening for electrical wires and
exhaust under the cabinet.
Vent option installation

NOT OVER TIGHTEN SCREWS. IT MAY CAUSE
DAMAGE TO THE HOOD.

(Figure 3) Keep 13 screws to install 3-1/4” x
10” exhaust & ven cover.
- Align and secure Top Vent Cover {E} and 3-
1/4” x 10” Exhaust {D} using 14 screws (13
screws taken from 6” exhaust. (Figure 4)
4. For Rear 3-1/4” x 10” vent installation only:
