Frequently Asked Questions


Every family has different cooking and food prep rituals, so we have compiled this list of questions we get every day hoping they help answer questions you may have and to help you decide which range hood is best for your home.

If you have any additional questions, please call us at (877) 901 5530.

 

What are some things to consider as I shop for a range hood?

THE SIZE OF YOUR COOKTOP: Measure it. Your range hood needs to cover the entirety of your range’s cooktop.

COOKTOP GAS OR ELECTRIC: Gas requires better ventilation due to the fact you are burning fuel.

THE AMOUNT OF TIME YOU SPEND COOKING AND THE WAY YOU USE YOUR COOKTOP: Do you "can" or "bottle" foods? Do you use "stock pots" in your meal preparation?

WHERE THE EXHAUST FROM YOUR HOOD WILL GO: Do you have ductwork to allow the air to be pushed out of your home, or will you need a recirculating or ductless range hood?

WHERE YOUR RANGE IS LOCATED: There are lots of options to fit your individual needs. There are wall hoods, island hoods, under cabinet hoods.

THE HOOD STYLE: There are lots of options here as well. You will find everything from contemporary hoods with a sleek modern look, stainless steel hoods, glass hoods, artisan or custom hoods with blower inserts. Do you prefer a touch panel or knobs you can push and turn?



HOODS


What size range hood do I need?

INDOOR: We recommend when you purchase a hood for indoor use they should be one size larger than your cooktop size (overlapping the cooktop by 3 to 6 inches on each side). For example, if your cooktop size is 30”, the ideal hood size is 36” or larger.

OUTDOOR: Hoods used for grilling outdoors should be 2 sizes larger than the cooking surface (overlapping the cooktop by 6 to 12 inches on each side). For example, if your cooktop is 30”, the ideal hood is 42” – 54”.


What does "CFM" mean?

A range hood’s power is measured in CFMs or "Cubic Feet per Minute." The larger the number, the more air the hood will remove.

Generally, the rule for a GAS cooktop is, for every 10,000 BTU your gas stove generates you will need 100 CFM. Example 60,000 BTU's = 600 CFM.

For an ELECTRIC stove, the CFM is estimated according to the size of the stove. You need 100 CFM for every 10" of stove width, so if your stove/cooktop is 36" then you will need at least 360 CFM.


How tall does my chimney need to be?

INDOOR: For indoor hoods, it depends on the height of your ceiling. All of our chimney style range hoods are telescoping, making the height adjustable. Most of our unaltered hoods accommodate 8-9’ ceilings. If your ceiling is taller, in most cases, an extension can be added to your hood for up to 12’ ceilings. For shorter ceilings, we offer custom cuts to get the perfect fit. Contact us to check the minimum chimney height on a hood or to see the lowest it can be cut down to.

If your hood can’t be vented through the ceiling (if you live in an apartment or condo), you may want to consider a ventless or ductless hood. This type of hood filters the air with a charcoal filter and recirculates it instead of redirecting the air to the outside.

OUTDOOR: It depends on the height of your outdoor structure. Most of our unaltered hoods accommodate 8-9’ structures. However, because we recommend a higher mounting clearance, some of our models will accommodate a taller outdoor structure. If you need additional chimney than what's provided, an extension can be added to your hood for up to 12’ ceilings. For shorter clearances, we offer custom cuts to get the perfect fit. Note: If you are using your hood outdoors, it must be sheltered in some way.


How high should my range hood be mounted?

INDOOR: If cooking indoors, we recommend allowing 28-36” between the bottom of the hood and your cooking surface. Less than 28” from the cooktop will put the heat too close to the electrical components, and more than 36” from the cooktop will start to decrease the efficiency of your hood. Adjust your hood anywhere within the 28-36” range to bring it to the desired eye level. The average height is 32” above the cooking surface.

OUTDOOR: We suggest you mount your outdoor hood no closer than 36” from your cooking surface. Outdoor grilling radiates intense heat, so the distance from the cooking surface should be farther than recommended for indoor cooking to prevent damage to the hood. The average outdoor mounting height is 36-42” above the cooking surface.


What is the difference between a ducted and ductless hood?

Ducted hoods vent outside of the home through the ceiling or a wall and are preferred to ductless models because impurities, odors, and pollutants from cooking ar expelled from the home entirely. They remove the air to the outside of the house through "ductwork" this ductwork is normally 6"-10". Additionally, ducted range hoods do not use or need charcoal filters saving the owner from having to buy and replace those filters. High BTU gas cooking equipment should always be ducted to the outside of the home.

Fully ducted range hoods are preferred but this is not always possible. Often called a "re-circulating range hood” a ductless hood will filter the air from cooking through carbon or charcoal filters removing grease and odors and return the air back into the kitchen area. While non-ducted filters trap some of the pollutants and odors from cooking, the smoke, humidity, and heat all re-circulate back into the home. If the filters are not replaced with regularity, eventually the ability of ductless hoods to catch pollutants becomes compromised and impurities will just be spread around the home.


Which is better, a ducted or ductless hood?

A ducted range hood is ideal if you have that option. Ductless hoods are a great alternative in other circumstances, such as if you live in an apartment or condo without access through the ceiling directly above your stove. While duct-free filters trap grease and odors from normal cooking, the humidity and heat will be re-circulated back into the home. Ductless charcoal filters must be replaced regularly (after 120 hours of cooking, or every 3-6 months) to continue to protect your home from impurities. We have several convertible hoods which can easily be installed as ductless or ducted, depending on your needs.

You must have a ducted hood in your home if you require a professional level hood with a high CFM.


How do I know if I need a professional level hood?

You’ll need to consider a hood with a higher CFM if you:

- frequently do a lot of frying or wok  style cooking

- grill on your range top (indoors or outdoors)

- cook ethnic, spicy, or fishy foods

- mount your hood outdoors

- have a range top with very high BTUs

- have an extra long run of ducting (especially with 90-degree bends)

- position your hood especially high over the range top (over 36”)

- want to keep the noise level down by choosing an extra powerful hood but running it at a lower setting


What is a sone and how is it measured?

A sone is a recognized unit of loudness and describes the sound output of your hood. The lower the sone value, the quieter the hood.

One sone is approximately the equivalent of a quiet refrigerator. Sone levels are the lowest when your hood is set to the lowest speed, and increase incrementally with each speed. Typically, the sone level is measured at maximum hood speed or CFM. Sones are a linear measure like inches. Doubling the sone value is equivalent to doubling the loudness.


Can I replace an over the range microwave with a range hood?

Yes. Whether your microwave blower is ductless or ducted, you can replace it with a range hood to ventilate your cooking area.

What is a "convertible" range hood?

A convertible hood is one that can be either ducted or ductless. In order to be a ductless hood, you either need an under cabinet conversion kit and/or charcoal filters. If you have any questions about your hood's ability to convert, call us (877) 901-5530. The charcoal filters needed for a ductless hood may need to be purchased separately.

I have a custom hood in my kitchen, does Proline Range Hoods sell hood inserts?

Yes. Proline Range Hoods does provide a number of inserts and blowers for custom hoods.

Does Proline Range Hoods design and build custom hoods?

Yes and no. We don't design and build custom hoods for customers from scratch, but we have a number of customizable artisan hoods that you can customize the finish of. We also provide a number of blower inserts designed to accommodate the ventilation needs of custom work done by other designers and manufacturers as well.

What inserts are available for a custom range hood?

All the inserts are designed for use with custom hoods or cabinetry. Proline offers the largest line of custom inserts in the industry. They will work in indoor and outdoor kitchens and lanais. If you don't see what you are looking for, please give us a call at (877) 901-5530. We can help you find the right insert to suit your kitchen!

How do you measure for an under cabinet range hood?

Measure the distance from the top of the range to the bottom of the hood. We recommend allowing 28-36” between the bottom of the hood and your cooking surface. You will want to make sure that you buy an under cabinet or wall mount range hood that, when fully installed, the bottom of the unit will be at least 28-36 inches above your cooktop. If you take the distance from your cook surface to the bottom of the cabinet and subtract the recommended 36 inches, and again subtracting the recommended 28 inches and you will be left with a distance range that your hood can be.


Installation and Ducting


Does my new range hood come with a transition?

We supply a courtesy transition piece with most of our models. Double check with us by calling (877) 901-5530.

Are Proline Range Hoods plug-in or hardwired?

Most Proline Range Hoods are just plugged into a standard 3 prong 110v/60hz grounded outlet. The only model that doesn’t come with a plug is our Hurricane model. It is meant to be hardwired directly into your home’s electrical system. If your range hood comes with a plug and you'd like to hardwire it, you can simply have an electrician do so.

Can I use an elbow in my ducting?

Yes. You'll simply need to make sure there is at least 18" of straight ductwork from the top of the unit before any elbows. You'll also need at least 18" of ductwork between elbows. Please note that every elbow you apply to your ducting will subtract 5' from your total duct run allowance.

Why can't I put an elbow on top of the hood?

Placing an elbow directly on top of your range hood will choke the airflow. It won't allow enough space for the air to flow properly and your Proline Range Hood will not perform as it should.

How long is the power cord?

The cord that comes with your hood is 4 feet.

Will my range hood work over my grill?

Yes. Make sure for every 10,000 BTU your grill generates your hood has 100 CFM. Example 60,000 BTU's = 600 CFM. **Recirculating hoods should not be used outdoors.


Can I return an extension I purchased?

Unfortunately, we do not accept returns of extensions or customizations of any kind.


How far can I run my ductwork?

You want the ductwork as short as possible with as few bends as possible. The farther the exhaust air has to travel and the more it changes direction, the more air pressure builds up in the ductwork and the effective CFM is reduced.


Why would I need a hood extension?

All of our chimney style range hoods are telescoping, making the height adjustable. Depending on the model as well as your ceiling height, you may need to purchase an extension.


Can I duct the range hood into my attic or crawl space?

No. You should never exhaust air into walls, ceilings, attics, crawl spaces or garages. The fumes and humidity collecting in those spaces will create issues for your home and family.

What type of ducting is best for proper ventilation?

Range hoods should be vented using metal ductwork. Smooth ducting is better than flexible or ribbed. This is because smooth straight ducting won't diminish or restrict the airflow as much as flexible ductwork will. That also needs to be taken into consideration when thinking or planning to add elbows to your ductwork.

Don't ever use 4" dryer duct or any plastic ducting on a range hood installation. The minimum size duct allowed on most range hoods is 3 ¼" by 10" which is equivalent to 6" round. More powerful hoods require even larger duct sizes up to 10" round. When remodeling, changing hoods, or cooking equipment, do not reduce the ductwork size to less than the size specified for the range hood. Decreasing the duct size restricts the performance and decreases the unit's longevity.

How far can I run my ductwork to exhaust my hood?

For maximum performance keep the ductwork as short and straight as possible. The maximum recommended duct run cannot exceed 30'. While 45° elbows are better than 90° elbows, please keep in mind that every elbow you apply to your ductwork will take 5' from your total duct allowance. If in doubt, consult a qualified designer/installer knowledgeable in ventilation, or call us and talk with one of our Customer Support Group (877) 901-5530.

My ceiling height is taller than most kitchens. What do I do about ventilation?

Custom chimney extensions are available for chimney style range hoods for up to 12' ceilings. If your ceiling is higher than 12', you may need to look into having your extension fabricated locally.


FILTERS



What are the different types of filters?

All of our hoods come with either a stainless steel baffle filter or an aluminum mesh filter. Both are dishwasher safe for easy cleaning.

If your hood will use ductless venting, you’ll need a charcoal filter in addition to either stainless steel or aluminum filters. This charcoal filter will cleanse the air in your home of grease and odors from cooking.

 


CFM



What is CFM?

CFM stands for cubic feet per minute of exhausting air flow. The CFM of your hood indicates the max power available when the hood is running at full speed.


What determines the CFM I need for my range hood?

The CFM you need will depend on several factors:

- the type and output of your cooktop

- your cooking style

- the size of the hood

- the length and configuration of your ductwork

Every situation is different, but it’s always better to have too much CFM than not enough. With a higher CFM, a greater amount of air is exhausted, which means it is cleaned faster.
If in doubt, consult a qualified designer/installer knowledgeable in ventilation, or give us a call and talk with one of our Customer Support Group (877) 901-5530.


How do I calculate the CFM requirements for my range top?

ELECTRIC: If you have an electric range top, the CFM is estimated according to the size of the stove. You’ll need 100 CFM per ever 10” width. For example, if your stove is 36” wide, you’ll need 360 CFM.
If you have an electric deep fat fryer, you will need to treat it as a gas stove top.

INDOOR: A good rule-of-thumb for gas ranges and grills is to divide the total BTUs by 100. For example, if your grill or gas range has a total of 30,000 BTU available, it will require a 300 CFM or higher rated hood.


Outdoor: Make sure for every 10,000 BTU your grill generates your hood has 100 CFM. Example 60,000 BTU's = 600 CFM. **Recirculating hoods should not be used outdoors.


What is considered a professional level CFM?

A hood with a CFM of 900 or higher is considered high output, or professional level hood.



Care and Maintenance of your Proline Range Hood


What's the best way to clean my range hood?

Use warm water and mild soap in the direction of the polish lines regularly to clean the outside of your range hood.
Rinse well with clear clean water and wipe dry immediately. For additional shine, you can apply a little coconut oil.
Don't use harsh or abrasive cleaning agents on your hood.


How often should I clean my range hood’s filters?

The steel baffle filters and aluminum mesh filters are completely dishwasher safe for easy cleaning. Clean them approximately every two weeks to a month depending on usage. Wash more often if your cooking style generates greater grease like frying foods or wok cooking. You cannot clean/wash the non-ducted carbon filters; they must be replaced.


How often should I replace my range hood’s filters?

With normal average cooking, you should replace your charcoal filters every three (3) to six (6) months, or if the air around the cooktop stops smelling clean when in use.


What kind of warranty comes with my Proline range hood?

All of our hoods come with a 3-year limited warranty. The first year we cover both parts and labor, while the second and third year we cover replacement parts only.
