CAUTION: For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
WARNING — TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
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.
Always turn hood ON when cooking at high heat or when cooking flaming foods.
Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
Use proper pan size. Always use cookware appropriate for the size of the surface element.
WARNING — TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING:
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.
NEVER PICK UP A FLAMING PAN — You may be burned.
DO NOT USE WATER, including wet dishcloths or towels — a violent steam explosion will result. Use an extinguisher ONLY if:
You know you have a Class ABC extinguisher, and you already know how to operate it.
The fire is small and contained in the area where it is started.
The fire department is being called.
You can fight the fire with your back to an exit.

Vented installation

Now start...

With range hood in kitchen.
Slide cardboard or hardboard under range before moving range across floor to prevent damaging floor covering.
Cover countertop, cooktop or set-in range with a thick, protective covering to prevent damaging countertop.
1.Disconnect and move freestanding
range from cabinet opening to provide easier access to upper cabinet and rear wall. Put a thick, protective covering over cooktop, set-in range or countertop to protect from damage or dirt.
2.Determine which venting method
(roof or wall venting or non-venting) you need to use. This range hood is shipped for non-vented installation.
If non-venting (recirculating) installation is desired, follow instructions on Panel D.

Venting requirements

Venting system must terminate to the outside.
Do not terminate the vent in an attic or other enclosed space.
Do not use four-inch laundry-type wall caps.
Do not use plastic vent.
Vent system needed for installation is not included. Wall or roof caps used must have backdraft damper.
Determine which outside venting method needs to be used. NOTE: If a non-vented (recirculating) installation is desired, follow instructions on Panel D.
The length of the vent system and number of elbows should be kept to a minimum to provide efficient performance. The size of the vent system should be uniform. Do Not install two elbows together. Use duct tape to seal all joints in the vent system. Vent system can terminate either through the roof or wall. Use caulking to seal exterior wall or roof opening around exhaust hood. For the most efficient and quiet operation, it is recommended that the range be vented vertically through the roof through 7" round vent system.
Figures 1-4 show common venting methods and what types of materials are needed.
