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.

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.

It is recommended that the wall or roof cap used have a backdraft damper. If it does, remove the damper from the range hood exhaust connection supplied with the hood.

Determine which outside venting method you need to use.

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 hood be vented vertically through the roof using 7" round vent system.

Flexible metal vent is Not recommended. If it is used, calculate each foot of flexible metal vent as two feet of straight metal vent. Flexible metal elbows count twice as much as standard elbows. Use metal ventwork only.

Figures 1-4 show common venting methods and what types of materials are needed.

Figure 4

Recommended vent system lengths for venting an electric indoor grill

Indoor electric grills produce more smoke than normal cooking and require at least 410 CFM to provide adequate ventilation.

Horizontal wall venting

Use maximum of two feet of 3-1/4" x 10" vent with a wall cap and a free discharge area of 66 square inches. There should be no elbows in vent system between range hood and wall cap.

Vertical roof venting

Use maximum of four feet of 3-1/4" x 10" vent terminating with a roof cap and with a free discharge area of at least 66 square inches.

If longer vent system is required, the shortest possible ventwork length should be used to ensure the maximum CFM of air movement for best venting. A transition to round must be used as close to the hood as possible to eliminate the restriction caused by 3-1/4" x 10" vent. 45° elbows should be used instead of 90° elbows wherever possible. A roof cap providing a free area of 113 square inches is recommended.

Check the length of vent system used with lengths given in the chart to make sure vent system length does not exceed static pressure of .25.
