What the Home Ventilation Institute(HVI) has to say about range hoods

PS31 SP Textured Black

 

Kitchen Range Hoods:

A kitchen range hood must move more air than a bathroom fan. about 50 to 140 L/s (100 to 300cfm) as a minimum. As a result, they are noisier, with the lowest rating about 4.5 sones, although they can be

relatively quiet on low speed.
The most useful units have a low noise rating, an energy-efficient fan, fluorescent lights, sound
insulation, anti-vibration mounts and duct connections. For heavy duty use, select non-corrosive
materials such as aluminum or stainless steel. High quality hoods may have heat sensors and a
safety shut-off.
Kitchen exhaust systems should discharge outdoors. Recirculating range hoods rely on filters to
capture some odours and grease. The filters are generally made of carbon which must be
replaced frequently to be effective. Grease will coat carbon, making it ineffective. With
recirculating fans, cooking moisture and odours will usually remain in the house.

Positioning:

Range hoods are most effective when they extend out over the stove surface and are close to the
stove top. Island units are less effective than wall units.

Cleaning:

Range hoods usually have washable, aluminum-mesh grease filters. Better quality filters have a
smaller diameter mesh over a larger surface area and can be cleaned in the dishwasher.

Fire:

There is always the possibility of a grease fire with a kitchen range hood exhaust. Smooth metal
ducting, preferably galvanized steel, is safer in a fire than lighter assemblies.

Installation:

Install fans and exhaust systems so they make the least possible noise, vibrate as little as possible
and leak as little air as possible.
Anti-vibration pads or foam tape can isolate the fan housing from wood joists and drywall. You
can wrap fan housings and some duct sections in rubber or vinyl noise barrier mats.
DuctsInstall exhaust systems according to the building code and manufacturer's recommendations.
Straight, short duct runs, with few turns, will result in the highest fan flow

Basic builder version under cabinet hood

A common situation we come across is new homes with the basic builder version under cabinet hood. Consumers mostly say the following:

• Its noisy
• It doesn't capture the smoke or vapour
• Its difficult to keep clean
• Grease accumulates on the cabinets around the range hood

Why do these problems exist:

• Builders are under pressure to keep costs as tight as possible - unless you request otherwise and pay for it they will install the most financially economical range hood they can
• The range hood has a $5 blower installed that probably draws between 100cfm and 300cfm
• The grease filters are aluminum mesh that has large holes in them - low density of mesh - saves money
• A combination of poor cfm/suction power and filters results in these problems

Here's your typical builder version range hood filter

Here's a picture of your typical 3 speed rocker switch under cabinet builder version range hood:

Dont get me wrong - i am not knocking these range hoods or the builders - i am merely pointing out that you get what you pay for.

So how do you resolve this issue as a home owner.

• Find out what duct size has been used and what type of ducting has been used
• Once you know this you can decide to use the existing duct work for a new range hood or modify this ducting to that which is suitable for the cfm your range requires which in turn drives the cfm capability of range hood you should have
• Establish the width available for a new range hood
• How high must the new range hood be to ensure that gap between the range and range hood is 30" to 34"
• Will there be unfinished cabinetry if you remove the existing range hood
• Research the market for an under cabinet range hood that will do the following
• Have adequate cfm for your range
• Requires a duct size that you can accomodate
• Is of course the correct width and height and depth to cover the heat elements on the range

Below features of a range hood solution we typically offer clients with the above situation:

Does your range hood perform as well as it should

Here are a few of the typical issues that consumes encounter with their range hoods and a brief look at why these issues may exist:

Problem = NOISY RANGE HOOD
Result = You don't use the range hood and the grease, vapors are spreading through your home

• The ducting is restricted
• This could be as a result of a back draft damper flap that is jammed in place creating back pressure on the blower - like all things in nature the blower responds and pushes back by increasing its effort
• The ducting is to small for the range hood blower
• Same situation as above - the rangehood blower works harder to get push the air out
• Filters are blocked - usually the case with mesh filters where the grease has congealed and the air cannot pass through easily
• Clean the venthood filters - if they are dishwasher safe - dishwasher otherwise by hand with a powerful detergent
• A cheap motor - as with most things in this world there are varying degrees of quality and a badly balanced and cheaply built range hood blower will make a great deal of mechanical noise

Problem =SMOKE AND COOKING FUMES ARE NOT BEING SUCKED IN BY THE RANGE HOOD
Result = Grease, vapors and odors spread through your home

• Blocked filters as above - this very rarely happens with baffle filters, it mostly happens with mesh filters
• Clean the filters
• The range hood blower system is under powered relative to the stove or range - in ventilation terms it is not drawing sufficient cfm(cubic feet per minute of air) to handle the volume of smoke or vapor being created by the range - very often happens over ranges with bbq's or griddles.
• Not much you can do except change the range hood blower - this has other implications - is the range hood ducting large enough to cope with the increased cfm - there is a correlation between cfm and range hood duct size - see other posts on this blog
• The capture area formed by the range hood does not cover the burners - when hot vapor rises it expands outwards like a funnel - if the range hood doesnt at least cover the burners you will have this problem
• Not much you can do again except a mjor reno and replace the range hood so that it covers the burners.
• A case in point - we were called to a consumers house who had a 48" wide by 27" deep wolf range with bbq - the client loved to bbq. However the hood above the range was only 14" deep - it was/is a beautiful 72" wide custom cabinet mantel hood. This was a big problem - not only are there no inserts on the market that are around 14" shallow by 48" wide there just is not the coverage - we came up with a solution for them - we bulit a custom 14" deep by 72" wide custom insert with baffle filters and only had baffle filters over the 48" space - we then added a 1000cfm external blower to the mix which creates a huge amount of negative air pressure through the filters - not a 100% solution but pretty close - most of the bbq work must be done at the back of the bbq. Picture doesn't show the whole story but there it is.

• Maybe you have a microwavehood - these typically suck in the air and then blow it back into the room - these are called re-circulating hoods - not much to say about these that is positive.

If you have any questions or live with these problems feel free to contact us - we provide advice and suggestions free of charge.

Remote range hoods blowers

Remote range hood blowers – also referred to as external or inline blowers

The majority of range hoods have the blower located inside of the range hood itself – internal blowers.

Internal Blower

Typically a remote blower is called for when a high cfm unit is required because the stove or range dictates it – link to blower sizing.

Exterior blowers are installed either on the roof or an external wall. Installing an external blower directly behind the range hood has limited value in reducing range hood noise – ideally there should be a bend in the duct run between the range hood and the exterior blower and it should be at least 10 feet distant from the range hood.

Inline blowers are installed in the duct run – as far down the end of the duct run as possible. These are a great option for efficiency and noise abatement provided an inline silencer is used – the inline range hood duct silencer works in very much the same way as a car muffler does. An important element in inline blower installation is to ensure the ducting is well secured to eliminate duct vibration.

Inline Blower

Remote range hood blowers are more efficient than interior blowers purely because it is easier to pull air (as a result of creating negative air pressure in the duct) than it is to push air – this of course pre-supposes that the duct sizing is correct.

Due to structural restrictions, such as a range hood being on an internal wall it is not possible to vent directly outside with a short duct run and less than 2 elbows – no matter what size blower is recommended for the stove it is recommended that a remote blower be used – the reason being of you have a complex and long duct run an internal blower will be very noisy even on the lowest speed setting because today’s high efficiency actually pick up their work rate when they sense high static pressure in the duct run – resistance. This then of course leads to duct size issues – the beauty of remote blowers is that they typically require smaller duct sizes than an equivalent cfm internal blower

What you need to know to install range hood ducting

Firstly we need to understand a critical element in range hood ducting – static pressure in the kitchen hood duct configuration

Follow this link to the author for additional useful range hood installation information

Static Pressure:
Inside every duct, there is a constant pressure being exerted at any point from all directions. When a range hood fan moves air through the duct, the air counters resistance from this pressure which is known as static pressure. Thus, kitchen venthood fan has to have the ability to overcome the static pressure in a duct so as to effectively duct stale air to the outside of your home. This can be done by calculating the equivalent duct length of any duct for the range hood ducting.

Calculating Equivalent Duct Length (EDL):
Simply measuring the length of a duct is not enough to know how much static pressure an exhaust fan has to overcome. Ducts may have one or more elbows, turns, or wall caps which add to the static pressure in a duct. Thus, you have to calculate the equivalent duct run and not the actual duct run so as to size an exhaust fan properly.

The static pressure in any duct run differs according to the material of the duct, number of elbows and turns, exterior wall cap and wall jacks etc. Listed below are the standard values for different duct components.

• Smooth metal duct:
• Actual duct length x 1 (eg. 3ft of duct = 3EDL

• Flex aluminum duct: Actual duct length x 1.25 (for 4”diameter duct)
• Actual duct length x 1.50 (for 6”diameter duct)

• Insulated flex duct: Actual duct length x 1.50 (for 4”diameter duct)
• Actual duct length x 2.00 (for 6”diameter duct)

• Wall caps/roof caps/back draft dampers: 30 feet for each cap (for 4”diameter duct)
• 40 feet for each cap (for 6”diameter duct)

      

• Elbows and turns: 15 feet for each (for 4”diameter duct)
• 20 feet for each (for 6”diameter duct)

For example assuming 6” ducting for the kitchen range hood:

 A rule of thumb is that a duct run for a range hood should not exceed 100EDL


Using the above values, you can calculate the equivalent straight duct length that an exhaust fan has to overcome so as to push stale air outside your home and counter static pressure effectively.

Range Hood Terminology

Common Range Hood Terms

A very common term used in ventilation is cfm – cubic feet per minute – this typically measures the volume of air that the hood can process in 1 minute and is an important metric in sizing the ventilation to your particular cooking environment.make up air. In the North of our great continent our new homes are almost 100% airtight – we make them so to keep drafts out. In the middle of winter everything is shut tight – we are cooking up a feast and we have our hood fan running on maximum and its sucking out 600cfm – that is 600 cubic feet of air every single minute – if our home is airtight where is the replacement air coming from – there is only one place it can come from and that is the exhaust pipes used by our furnaces, water tanks and fireplaces that are working at expelling carbon dioxide and a ton of other lethal gases – the result is that we fill our house up with poisonous gases – there have actually been a few deaths from this. The only way to combat this and still keep our beloved kitchen ventilation is to install a make up air system – a system that replaces the air in a controlled fashion as the range hood sucks it out. This is a pretty complex area and can also get very costly. There is no real regulation on this yet but authorities have set cfm limits that can be used in certain areas – typically very low at that – this is very frustrating for a ventilation person because we must match the cfm to the cooking equipment and if we can’t get enough cfm our whole effort at kitchen ventilation will be futile.More ventilation terminology- British Thermal Units – this is a measure of the heat output of the cooking appliances.Canopy – The decorative exterior of the system – sometimes referred to as a shell and can also be a wooden or stone canopy – see liner below



Duct or Ducting – The pipework that the collected is expelled throughExternal Blower - A blower unit that is mounted on the outside of the home.


Inline blower – a blower that is installed between the range hood and the outside – typically in the duct run

Liner or Insert - A non decorative range hood that is installed into the underside of a decorative wooden canopyInternal Blower – A blower that is inside the range hood canopy.

You may also hear of a term static pressure – very basically this is like horse power but the measuring and applying it gets pretty complex and is therefore mostly ignored.

Standard range hoods are available in widths of 24, 30, 36, 42, and 48 inches. For normal cooking needs, select a size that will as a minimum match or closely approximate the area taken up by the burners. (With high-performance cooking equipment, the manufacturer may recommend some overlap, perhaps 3 inches or more on each side.)

In deciding how powerful a fan you will need in the range hood, consider three things: the amount of cooking, the type of cooking generally done in the kitchen and the power(know as btu - British thermal unit - a measure of energy for gas or watts for electric) delivered by the cook top. The more frying and steaming that is likely to occur, the higher the cfm (cubic feet of air per minute) you will want handled. Fortunately the ventilation industry has developed a rule of thumb for cfm required - 1cfm for every 100btu's of cook top output - this can be calculated, by looking up in the owner’s manual for your particular cook top, the given btu's of each burner/cooking spot and add them ALL together - this presupposes the worst case ventilation scenario - all burners are on at the same time and running on the highest setting.

Finally we have a relatively new term –

BTU

How high should the range hood be installed

What height do you need?

Determining the proper height for your rangehood is a simple matter as long as you know the height of your ceiling.  Let say for example that your ceilings are 9ft high, that’s 108 inches.  You would then take the total 108 inches and deduct 36 inches for the height of your range leaving you 72 inches.  Then you will need to determine how high you would like your range hood off of your cooktop.  Modern-Aire recommends hanging your vent hood 30-34 inches above the cooking surface for optimal performance, so let’s just say that you have decided to hang it 33 inches above the cooking surface. You have 72 inches remaining, so deduct the 33 inches for the distance between your cooking surface and the bottom of your range hood and you now have a total hood height of 39 inches.

Wooden Range Hood Canopy Insert

This wooden range hood canopy - otherwise known as a mantel hood - posed some challenges as it was only 14" deep and 72" wide and was over a 27" deep by 48" wide professional range with a griddle and the client BBQ's extensively indoors during the cold Ontario winters. The challenge comes in that ideally there should be full coverage over the burners otherwise any cooking that took place on the front of the stove would not be captured by the hood.

We therefore needed to maximize the suction over the immediate cooking surface and accomplished this by placing flat panels on either side of the range hood capture area where the baffle filters where placed. Suction was achieved with a variable speed 1000cm external range hood blower. Lighting is dimmable halogen range hood lighting.
