Broan Range Hoods Fuses Classic Style With Modern Performance

What emerges when performance, durability and tradition are combined into one kitchen ventilation product? The result is the new, expertly crafted WT32 Series of Chimney Hoods, from BROAN®, which is intelligent and
high-performing in its execution and elegant and classic in its traditional Italian-inspired design.
In response to the current economic climate, Broan has created a value-engineered entry-level chimney hood, without sacrificing style and performance. As part of the BROAN Colonne Suite of cooking ventilation products, the WT32 chimney hood is a robust expression of Italian style that pays homage to the classic Roman Architecture. Both striking and simple in design, this range hood gives new meaning to the idea of achievable luxury.
"Modeled after one of our most popular designs, the WT32 chimney hood is perfect for today's upscale residential kitchens," says Brian Wellnitz, marketing manager, kitchen ventilation, Broan-NuTone®. "We are proud to offer our consumers a luxurious, durable, long-lasting product that is more accessible. Featuring modern controls, lighting and automatic heat detection and stunning Italian-inspired craftsmanship, the WT32 Series can adapt to both modern and traditional kitchen designs. As with other Broan range hoods, even with the latest technologically advanced control features, it still remains a very user-friendly ventilation solution.
The new WT32 range hood has a unique four-speed electronic push button control with translucent blue backlit indication that allows the user to easily determine which speed has been selected. Additionally, it includes a delay timer that automatically shuts off the range hood after five minutes to ensure all cooking contaminates have been evacuated from the kitchen and will indicate when it is time to clean the filters.
"In conjunction with the Broan damper, the WT32 series helps decrease indoor air pollution by restoring fresh air in the home every time the chimney hood is used. As indoor air quality is more and more of a concern for homeowners, Broan continues to offer top of the line, stylish range hood options, helping to eliminate unwanted odors and indoor air pollutants to ensure a healthier home. The WT32 chimney hood might derive its style from ancient Rome, but its function and features are distinctly modern," says Wellnitz.
The durable, brushed stainless steel chimney hood models are available in 30-, 36-, 42- or 48-inch widths and a 22-inch depth. The models are equipped with powerful Pro 600 CFM or Super Pro 1,200 CFM blowers engineered for optimal function and whisper-quiet operation.
Additional features of the Broan WT32 Series include:
  • Brilliant halogen cook top lighting: two 50-watt bulbs in the 30- and 36-inch model widths and three in the 42- and 48-inch model widths
  • Dishwasher-safe, quick-release, stainless steel and mesh filters
  • Optional non-ducted recirculation kit available with 30- and 42-inch width hoods when outdoor venting is unavailable
  • The Heat SentryTM system, which automatically detects excessive heat and adjusts blower speed accordingly

What does CFM mean?
CFM is the acronym for Cubic Feet Per Minute - the measure of air volume moved by the fan blower. Choose a fan with a CFM rating appropriate for your room size to ensure adequate ventilation.
What is a Sone, and how is it measured?
A Sone is a measurement of sound in terms of comfortable hearing level for an average listener. The lower the sone value, the more comfortable the listening environment. Sones are not decibels or volume, but rather how sound is "sensed". One sone is the equivalent of a quiet refrigerator.
What is continuous ventilation?
Continuous ventilation provides today?s airtight homes with a relatively constant and controlled lower level of ventilation.
Can I mount fans above my tub and shower?
Most fans are rated for use over a shower or bathtub with a GFCI (Ground Fault Circuit Interrupter).

Can my ceiling fan be surrounded by insulation?
Yes. Bath fans are designed to provide adequate cooling for motors and lighting, as well as products with integral heaters.
Will fans work in wall-mount applications?
Some bath and utility fans may be wall mounted. See the spec matrix for specific models. Improper installation may affect fan life, safety and your warranty.
Will a ceiling fan or wall-mount utility fan serve as a range hood?
No. Range hoods are specifically designed to handle grease and high temperature environments. Ventilation provided by NuTone fans is only a supplement for odor and moisture removal in the kitchen.
What does "static pressure" mean?
Static pressure is the measurement of airflow resistance as it is pushed through ductwork which reduces the effectiveness of the fan. Learn more on the Home Ventilation Institute web site

How long should a bath fan run after a shower is used?
The Home Ventilation Institute recommends that a fan should be left on for 20 minutes more to clear humidity adequately and to ensure moisture and condensation in the fan body or ducting is minimized.
What should I do if I can't wait for moisture to clear, but I don't want a fan to run all day long.
Sensing fans that detect the humidity rise caused by a shower and turn on automatically, when moisture has cleared it turns off. Some wall controls also give you the option of humidity sensing, or timer control. Just set it and forget it.
What are the timer features?
Delay-off timers automatically shut your fan off after a specified time interval. It?s a nice feature in high traffic bathrooms where you may wish to let the fan run to clear moisture adequately. A timer counts down the minutes of fan operation selected by the user.
Where should the exhaust fan be located?
Exhaust fans should be located in or near the shower or tub, and in an enclosed water closet. Keep exhaust points opposite the supply air source to ensure that the fresh air is drawn through the room. Bathroom doors should not be sealed too tightly at the bottom in order to allow "makeup air" to enter the room when the door is closed.

Where is the exhaust outlet on the ventilation fan?
The exhaust outlet is the point where air is discharged through the body of the fan housing into the ductwork. During installation, orient your fan with the exhaust outlet pointing toward the exit vent on your roof or wall to minimize turns in ductwork that impede airflow.
Why do the windows and mirrors fog even when the fan is running?
If windows and mirrors are very cold, condensation can still form on these surfaces. And if your bathroom is sealed tightly, replacement air may not be entering the room fast enough to displace the moist air. Be sure to undercut your door sufficiently to draw fresh air into the room. Fan placement can also be a factor. Your fan should be located far from the replacement air source to ensure the moist air is drawn out first. Finally, too many twists and turns in the ducting will significantly reduce the ability of the blower to remove moist air. Make sure your ductwork is as short and straight as it can be, with gradual turns rather than tight corners where necessary.
Why is water dripping from the grille of the fan?
Dripping water is either condensation (usually due to cold ductwork or improper duct installation), or a problem with the seal on a wall or roof vent. Insulated ductwork can help solve condensation problems, and running the fan longer will ensure moisture is completely removed from the duct. Ductwork should slope down toward a wall vent to direct condensation out of the exterior vent opening rather than back into the fan housing.
Can I install a heater over the bathtub or in a shower?
No. Heaters are not UL Listed (Underwriter's Laboratory) for installation over a bathtub or in a shower.

Can I use an inline or multi-port fan in one large bathroom?
Yes, this works the best for large rooms because you can install the ports over the areas where the ventilation is needed the most (source control). The size of the multi-port would be determined by the size of the room.
Does a duct-free bath fan expel air?
No. A duct-free fan is not a ventilating device. It does not remove air from the room.
What type of exhaust fan is recommended for hot tub areas?
A high CFM rated device is normally recommended for this type of application.
Can I use a smaller diameter duct than what the fan is designed for?
This is not recommended. It will cause the fan to run harder, greatly reducing the CFM performance of the fan and create excess noise.

Can larger diameter ducting be used with my bath fan?
Yes, larger diameters will result in improved performance.
What type of duct is recommended, rigid or flexible?
It is recommended, where possible, to use rigid duct. It has less resistance to air flow and allows the fan to operate much more efficiently. If flexible duct is used, be sure the duct is as straight as possible.
Can I exhaust my fan into my attic instead of out the roof or wall?
Never exhaust air into spaces within walls, ceilings, attics, crawl spaces or garages. The humidity may damage the structure and insulation.
What type of exhaust fan is best for a sauna or hot tub area?
High CFM-rated devices are normally recommended for this type of application.

Can I use a fan in a steam shower?
No. Since these are normally sealed chambers, a vacuum will be created.
Can I vent more than one bath fan out of a roof or wall cap?
No. Always follow the manufacturer's recommended ventilation requirements.

Fixing That Old Attic Fan

Whole house or attic fans are a wonderful thing to have and often replace air conditioning units for people in climates where the evenings are cool in the summer. When the attic fan is working properly, it provides an air exchange for the entire house and encourages breezes to flow freely through the rooms. If the fan has stopped working, you may think you have to call in a repairman, but the job may be simple enough to do yourself.

things you'll need:
Voltage sensor
Extension cord
Electric light
Parts as needed

Identify the problem. This may sound simple enough, but the way you proceed depends heavily on the source of the problem. Many fans have either motor malfunctions or troubles with a thermostat.
Diagnose electrical problems with an extension cord. If your fan plugs into a standard outlet, simply bring an extension cord and a small lamp up to the attic with you. Keep the extension cord plugged into another outlet, plug the fan into it and see what happens. If the fan works, then you've probably got an electrical problem. Try plugging the lamp into the outlet dedicated to the fan; if it doesn't work, you've identified the problem.
Check the thermostat. Many attic fans stop working because of a problem with the thermostat. If your fan has an "off/on" switch that can bypass the thermostat, try that and see if the fan turns on. If it does, you've found the problem. If it doesn't have that option, remove the thermostat to see if the fan still functions. Be sure to disconnect any electricity at this point.
Get the right parts for the job. If you've diagnosed a motor or thermostat problem, you should be able to get the parts at
Replace the parts. Once you've got the parts, you can easily follow the manufacturer's instructions for replacing the problem part.

Remember that your fan is an electrical appliance. Use every precaution when dealing with electrical items and turn off the electricity from the circuit breaker whenever you are working on them. Check your paperwork for a warranty before you begin your repair. Your fan's problem may be covered and you may get a free replacement part, service or even a new fan if yours is still covered. Check your prices; sometimes it's cheaper and easier to replace the fan than it is to repair it.

While doing it yourself is very satisfying, you don't want to pay more for the parts than you would to get a brand new fan.If your problem is within the electrical system of your house and you don't have experience with wiring, seek professional help. Electrical work can be tricky and dangerous and if you feel you are in over your head, you probably are
