Frequently Asked Questions - NTM302SS NuTone

How do I install the NTM302SS range hood?

Refer to the installation manual. Typically, you need to mount the hood under a cabinet at least 18 inches above the cooktop, connect the ductwork (if vented), and wire to a 120V power source. Ensure the unit is level and securely fastened.

Can I use the hood in recirculating mode?

Yes, the NTM302SS can be used in recirculating mode by installing a charcoal filter (model NTMCHF30). The charcoal filter absorbs odors; it should be replaced every 3-6 months.

How do I clean the grease filter?

The aluminum mesh grease filter is dishwasher safe. Remove it from the hood and wash in hot water with detergent, or place in the dishwasher on a light cycle. Allow to dry completely before reinstalling.

What type of light bulbs does this hood use?

The hood uses two 40W incandescent bulbs with an E12 base (candelabra). You can also use LED replacements of the same size and base type for energy efficiency.

Why is my range hood making a loud noise?

Check if the fan blades are obstructed or if the grease filter is dirty. Also ensure the unit is mounted securely. Loose ductwork or a worn motor bearing can also cause noise. If persistent, consult customer support.

What is the recommended duct size for vented installation?

The recommended duct size is 6 inches round (15.2 cm). Use smooth metal ductwork for best performance and minimize the number of elbows to reduce airflow restriction.

How often should I replace the charcoal filter?

If using recirculating mode, replace the charcoal filter every 3 to 6 months, depending on usage. A saturated filter cannot absorb odors effectively.

Can I install this hood over an island?

The NTM302SS is designed for under-cabinet or wall-mount installation. It is not recommended for island installation unless an island canopy kit is used (check compatibility with NuTone).

How do I reset the filter reminder light?

The NTM302SS does not have a filter reminder light. If your model has one, press and hold the filter reset button for 3 seconds. Otherwise, manually note when filters are cleaned.

What is the warranty on my NuTone range hood?

The NTM302SS comes with a 1-year limited warranty covering parts and labor for defects in material or workmanship. Proof of purchase is required. For service, contact NuTone customer support.

IMPORTANT SAFETY INSTRUCTIONS

⚠ WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSON(S), OBSERVE THE FOLLOWING:

1. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer at the address or telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service panel and lock service disconnecting means 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.
3. Installation work and electrical wiring must be done by qualified personnel in accordance with all applicable codes and standards, including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer's guidelines 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.
5. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
6. Ducted fans must always be vented to the outdoors.
7. Do not use this unit with any solid-state speed control device.
8. To reduce the risk of fire, use only metal ductwork.
9. This unit must be grounded.
10. When performing installation, servicing or cleaning the unit, it is recommended to wear safety glasses and gloves.
11. When applicable local regulations comprises more restrictive installation and/or certification requirements, the aforementioned requirements prevail on those of this document and the installer agrees to conform to these at his own expenses.

TO REDUCE THE RISK OF A 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 foods (i.e.: Crêpes Suzette, Cherries Jubilee, Peppercorn Beef Flambé).
c) Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan, filters or in exhaust ducts.
d) Use proper pan size. Always use cookware appropriate for the size of the surface element.

⚠ WARNING

TO REDUCE THE RISK OF INJURY TO PERSON(S) IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING*:

1. 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.
2. NEVER PICK UP A FLAMING PAN — You may be burned.
3. DO NOT USE WATER, including wet dishcloths or towels — This could cause a violent steam explosion.
4. Use an extinguisher ONLY if:

A. You own a Class ABC extinguisher and you 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.

* Based on "Kitchen Fire Safety Tips" published by NFPA.

CAUTION

1. For indoor use only.
2. For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
3. To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc. off power unit.
4. Your hood motors have a thermal overload which will automatically shut off the motors if it becomes overheated. The motors will restart when it cools down. If the motors continues to shut off and restart, have the hood serviced.
5. The bottom of the hood MUST NOT BE LESS than 26" and at a maximum of 30" above cooktop for best capture of cooking impurities. For a gas range, the bottom of the hood MUST NOT BE LESS than 28" above cooktop.
6. Two installers are recommended because of the size of this hood.
7. To reduce the risk of fire and to properly exhaust air, be sure to duct air outside — Do not exhaust air into spaces within walls or ceiling or into attics, crawl space or garage.
8. Because of the high exhausting capacity of this hood, you should make sure enough air is entering the house to replace exhausted air by opening a window close to or in the kitchen.
9. Please read specification label on product for further information and requirements.
