Ways To Install A Ductless Range Hood

Step 1: Plan ahead when installing a ductless hood

When you start cutting against the wall, you can’t accurately put that wall together – not easy anyway. Therefore, it is paramount that you choose where your piping can operate. For the entire pipe run, you can have huge rivets along the way – in addition, if you caught cord or other wiring, piping can run through that area. You will need to look for another way for it. Ideally, the ducts should run unobstructed to the outside of your house.

You also can let it through the wall or out to the ceiling, which we will discuss below. 

Step 2: Decide the position to install your range hood

The first thing you should do before installing a hood you need to do is answer the question: Should we vent the hood through the wall or on the roof? The position of your range will probably decide this. If you choose where you operate the pipeline, the path with least resistance is what? The shortest path to the outside is blocked by a wire or an obstacle is what ?

Some hoods can be installed with a kind of duct. Island hoods have to vent through your ceiling, while wall-mounted hood can be vented through the wall or ceiling, depending on your kitchen design. 

Step 3: Get measurements

Determine the height of your ductless hood and install a hood between 28 ”and 36” above your stove.

After deciding on your model on how to install and where to install the ductless hood, measure the height and length of your ductless range hood. Mark the wall measurement you selected in step 2.

Mark your screw hole measurements or the mounting points of your ductless hood. Mark the center and two points mounted on cardboard. 

Then you have this dimension, take a big piece of cardboards and fold it with the hood’s back. Crafting hood on your cardboard and mark two mounting points and the center. 

Afterward, cut the contour of your hood. When done, put a cardboard sign on your wall that says the upper part of the hood.

And the last thing is drilling through the wall of cardboard where you marked the mounting points. Let’s drill into the screw head because that’s where the screw will be in the hood.

Step 4:Use hard pipes

To make the most of your hood, install it with hard piping. The material is more durable than the hose, which will easily cause matters for you during your first year of use.

Keep an 18 ”space between your elbows.

Some of the next tips concentrate on maximizing the effectiveness of your duct hood. Allow 18 ”straight pipes to operate between each elbow to decrease internal resistance of your ductwork.

When the elbows narrow the distance from each other, grease can accumulate in the joints, reducing the hood’s efficiency. Additionally, each elbow has additional drag in the duct system, so the atmosphere slowed.

Actually, it may not take place completely outside of your home that could lead to reverse drafting. Reverse retraction happens when there lacks power to transfer the air in your kitchen to outside. As a consequence, cooking smoke seeps back into your kitchen, instead of escaping outside of your house. 

The elbow must be longer than 18 ”from the hood

It is vital to gaps between the elbow as well as from top to elbow hood first. Otherwise, a large amount of grease will accumulate in the elbow joint over time and greatly reduce the hood’s efficiency. 

Employ no more than two twisted segments.

To ensure the hood runs as effectively as possible, use less than two elbows in your duct system. More than two bends are simply subject to too much drag and the atmosphere will not flow easily to the outside.

In idea, as long as you keep your hood filters, there is no need to clean your hood pipes. Two elbows or more negatively influence the flow of air, further straining the engine of your hood. Grease can build up and you may pay for duct maintenance. 

Plumbing cleaning is a professional area that can be very expensive. If you follow these tips settings, your hood will be in good form. 

Step 5: Apply the latch and screws for hanging hood

Drill two latches and then screwed into the hole you created. This will allow you to hang the range hood against the wall. 

Step 6: Use your studs to drill the support screws

When the hood has been mounted already, lift it up to find the position of the studs you marked them in step 3. Then, you can use the two grab screws to drill into the hood’s back. Check out that your hood is flat. Now you are installing chimneys. 

Step 7: Locate you will connect the mains to the hood

You need an outlet placed on the ceiling, so you can drill a hole to thread the power cord then plug through the ceiling for plugging into the hood. 4 ‘cord is included with all hoods so remember when making your installation. 

Step 8: Install a chimney bracket for attaching the top of the chimney

A chimney holder will be included with your hood. This piece will attach to the back of your chimney piece by drilling through two holes in the rack. Similar to step 3, you’ll want the size of the brackets and note the center of gravity. 

Marking on the frame indicates the central point so you can align the frame with the central point on the ceiling marked. Then, using a pencil mark the screw holes in the wall. 

Next to the previous step is drilling two accessories of sheetrock and then drilling holes into the sheetrock anchor of the accessories there.

This will anchor the mounting bracket to the wall to your chimney. Now, screwing the bracket to the wall. 

Step 9: Install the chimney

Get the protective plastic debris out of the chimney and paste some pieces of paper on which you will slide the pieces into and out. This will avoid scratching of stainless steel while you’re adjusting the chimney during installation.

To measure the length of the chimney, measure the gap between the head of the hood and the ceiling. Then adjust the pieces of your chimney to fit this length and paste the inside to the pieces and move around. Then attach the chimney above the hood.

It will be anchored by four screws on the side of the chimney: two screws above and below the two screws. The top screws will attach to the mounting bracket and the bottom will secure to the side of the hood. 

Step 10: Check out the range hood.

When the chimney of the range has been installed, the hood in position and the power has been connected, check the range hood. If the hood is not enabled, please check that the machine has been properly plugged in and is not loose connection inside the range hood. 

Step 11: Installation of a damper

A damper looks like the roof flap in that it maintains dirt and debris out of your duct. The major difference between the reverse shaft damper and the cap is that the reverse shaft damper has been inside the duct system.

The regulator not only prevents debris from coming out, but also avoids back stretching. In other means, it prevents air remount and return pipes in your house. The reverse damper is basically a stainless steel vent which opens while the range hood is running to let air to escape and closes once your hood is off. 

What Is A Ductless Range Hood? How It Works?

A cooker hood is an increasingly important kitchen appliance in every one of our lives. It has the ability to absorb the smell of food in the kitchen, bringing fresh air to the whole room.

Not only that, the hood also becomes one of the kitchen equipment that contributes to a modern, sophisticated and luxurious kitchen.

But installing a hood is always not easy, because it depends on many factors. Factors determining the type of hood installation.

And one of the cases when installing a hood is the type of installing a hood without an exhaust pipe (also known as: a hood without an exhaust pipe).

Reality has shown: when affected by factors such as: limited kitchen space or design in the architect’s planning, we have to choose the hoods that do not need a drain exhaust to the outside (the hood does not need a drain), however, we are not really assured.

You may be worried: do not know if it is any different from installing a hood with a drain or not?

Or how does it work? Is it effective or not? All of them are in the following section of the article.

The cleaning mechanism of the hood

As you know, there are many types of hoods on the market, but there are still only 2 ways to clean the smell of food in the kitchen:

Method 1

Use the “recirculating air filtration” mode without the need for exhaust pipes. Accordingly, the gas will pass through the steel filter to filter out grease and other foreign objects or dust and be sucked into the machine.

The smell and smoke substances will be filtered by screens (made from activated carbon) and filtered and released into the air (this gas has been filtered before being released into the environment).

 Method 2

It is the use of the exhaust pipe to allow the air in the kitchen to escape. In this way, the hood will work on a mechanism: suck the air and push it directly out of the kitchen.

With this way, you usually do not need to use activated carbon to filter clean anymore and the machine will suck well.

So: “What models of hoods are currently not using a drain?”

In fact, almost all types of hoods have both a recirculating air filter and use an exhaust pipe to the outside.

However, it also depends on economic costs and architectural conditions of your family to decide whether to use or not. Of course, each hood will have a different design so the charcoal deodorizing it is also a little different. 

Advantages And Disadvantages Of The Hood Without An Escape Tube?

When we install a hood without a drain, it gives us outstanding advantages and limitations that we need to consider:


The hood without exhaust pipes will be more compact and save kitchen space, and at the same time the kitchen will become delicate with high aesthetics, without having to chisel the wall to install the exhaust pipe.

The hood is very strong, the ability to quickly clean the air, cool the kitchen (because when installed, the hood needs the exhaust pipe to bring hot air out of the kitchen).


 When installing a hood without a drain, you will have to regularly change charcoal (every 6 – 12 months) while the cost of replacing activated carbon briquettes is not cheap at all (depending on the company).

Although a hood that needs a drain has many great advantages, it still has certain limitations such as: need to chisel the wall – this will lose the aesthetic of the kitchen space.

In particular, the initial cost to buy air ducts is very large, they will not be appropriate if your kitchen area is too small.

But in terms of hood efficiency, Nam Duong Kitchen will encourage you to use the hood with the exhaust to the kitchen so that the kitchen is always clean, fresh and not hot.

However, if your kitchen is in an apartment room with a small area, you should use built-in hoods: deep in the kitchen cabinet, compact, aesthetic and maximum saving of kitchen space. .

Then, you can use the recirculating air filter mode, not using the exhaust to clean.

In addition, in case your kitchen is in the villa and the kitchen is located in the middle of the house, you are required to use an independent hood (island hood) to use it.

When buying a hood, it is better to choose a model with an adjustable power range, which will give the opportunity for better control of its operation. In addition, it is worth noting that the hood parameters must correspond to or not be less than the size of the stove and oven.

It is worth knowing that a small kitchen does not need a hood with maximum capacity, because, the larger the capacity, the more noise it will cause during operation. By far the most optimal performance for the power of this device is considered for a capacity of about 300-600 cubic meters per hour.


The ductless kitchen hood contains two filter options: Coal, its function is to clean the air of smoke, soot, burning, odors and smoke.

Grease, designed for the purification of the air of fats.
