How to install a chimney pipe in a wood-burning stove through a wall?

Install your wood stove fireplace pipe through the wall only if you have no other alternative, because the stove will burn better the longer the fireplace stays inside the hot house, as it will have a better air flow and generate less creosote. You should also use a “Class A” chimney pipe which is rated for 2,100 degrees Fahrenheit (1,148 degrees Celsius) and approved to pass through walls, as this will save your home in the event of a fire. Keep reading to learn how to properly install your fireplace through the wall.


  1. Determine where the chimney will exit the wall and cut a hole that corresponds to the diameter of the chimney.
  2. Insert the supplied wall thimble or radiation shield into the hole and clamp or screw it into place. Put silicone putty on the joint between the wall and the shield or thimble.
  3. Attach the required horizontal chimney length to the clean stand and insert it through the wall inside the house. The fireplace should extend into the room at least four inches (10.16 cm). Put the pipe extension between the stove and the chimney and attach it with the screws provided.
  4. Insert a vertical section of the fireplace into the bracket and adjust the top section to the outside of the house with a wall bracket. Keep the fireplace at least 2 inches (5.08 cm) from the wall.
  5. Add additional chimney sections as necessary and adjust to the wall at least every 8 feet (2.44 m). Align the vertical seams so that the screw holes are aligned. Screw the sections together. The chimney should extend at least 3 feet (0.91 m) beyond the roof and be at least 2 feet (0.61 m) higher than anything within 10 feet (3.05 m).
  6. Engage the rain cover on top of the chimney and tighten it with the screws provided.


Tips and warnings

  • You can attach your fireplace to match the exterior of your home, but be sure to keep a 2-inch (5.08 cm) space between the fireplace and any flammable material.
  • Do not enclose the base of the clean support and do not fill the enclosure with insulation.
  • Check your fireplace at least every two months during the heating season to keep track of the creosote buildup.


How to clean the bricks of the fireplace

Chimney bricks are able to withstand high temperatures without much maintenance. After years of fire, the bricks can get dirty with the soot of charcoal from burned firewood. Too much soot can cause too much smoke in the chimney, which produces carbon monoxide dangerous for poisoning. Clean the bricks before starting each season.


  1. Mix 1 ounce (30 ml) of liquid soap with plenty of table salt in a bucket. Mix it with a little water to make a thick paste.
  2. Spread the pasta on the bricks of the fireplace and let it sit and dry for at least 10 minutes.
  3. Rub the paste on the bricks with a hard chimney brush.
  4. Rinse the bricks with a little warm water to remove the salt residue and prevent salt marks from forming on the bricks.

How to build the lintel of the stove

Continuing with this manual, it is time to build the hood, the lintel and attach a smoke oven to the flue.

Previously we built the home and detailed the function of the angled walls, the construction of the lung and collinear. In the upper part we formed the throat, to which we gave 14 cm (two more than normal), then we will install a balanced shot of sheet to ensure a good combustion and a proper evacuation of the gases produced by this.

The walls are still fresh, they gave form to the half point of mouth, and in this step that we will give construction to the lintel we must have particular attention in not excessively damaging when placing the bricks. Excessive fatigue on the base could cause the brick work to fall out. If you have doubts or are insecure, let it dry a couple of days more. But if you are careful then

For the lintel we will use the bricks supported by rope (regard sardine) separated if not less than 2 cm and we will locate them united by their faces, the objective is that in this part we have a ledge that will serve to support, because its destiny is to the height of elbow 1.10 cm and will be part of the projected rustic decoration and we will use it to support the pots that we will later introduce to the oven.

If this stove is designed for the incorporation of a smoker oven, if it is not interested in this part, it is advisable to give its construction by reinforcing the structure that means this way of lifting the wall.

This ledge will make us beam, so the reign of the joints should be made with sand and Portland, while the views will continue with the same we use to settle so that it does not change the color of finish that we are giving to the bag.

We will see half of the brick, in the photo above it is seen how the previous part that integrated the wall of the hood with reinforced mixture was filled and the front will be continued with common mortar, this part is critical in the decoration, as it is one of the pairs that stand out in this design, for which we should devote a good effort in your bag, it is convenient to place a board under the bricks while filling the joints to facilitate the task. It would also be good at this moment of the execution to discard the sponge that we had been using and start again with a new one.

In this part we decided to cover the smoke chamber with veneered bricks, as it seemed neater than leaving the plaster of the wall, in passing we ensure that unwanted leaks do not originate and leave the work of the house totally independent of the structure of the house.

Another aspect that we found interesting, as we are going to hang meat here for smoking is more convenient to clean even in this part could cover the interior with tiles or ceramics, this will depend on the taste of each one, we will do the work by bolting the bricks of the smoke chamber.

If it were for heating, exclusively, we should rethink the lateral lining, since the heat delivery to the next room will be less when installing this brick wall.


Continuing with the bell, which is the part that follows the lintel, whose principle is to act as a smoke absorber and as a channel to the pipeline, we will raise 4 courses the first two will close the triangle while the others will be decoration and they will be the base of the furnace, as you may have noticed we have not used irons.

This is because the way to place the bricks means the points generate a self-supporting mechanics that give great resistance to the chimney, for example the weight of the mouth of the chimney is distributed across the arch to the side walls of the chimney. In the same way, the flue of the chimney will support them in an arch that will be the door of the furnace which will distribute that enormous weight towards the side, transferring its weight just on the sides of the hearth.

These first two courses should be placed as far back as possible, this is to get the ledge to gain the largest possible useful surface, and at the same time get the closure of the bell, this is that the triangle will close us little by little until the pipeline.

To achieve this closing effect, it is convenient to install a wooden or metal reinforcement, where the bricks are supported as we are closing the courses inwards, in the drawing it is better detailed. The stick prevents the wood from sticking and facilitates the removal of the same after setting by the mouth of the home, as we see this passes without problems through the throat, try to try before installing it out below or otherwise we must leave it installed and it will burn when we light the fireplace.-

The next two courses will be the base of the furnace mouth or, failing that, the base of the bell roof where we will then continue the pipeline. To solve the integration of the cover to the set without using concrete or iron, we have run the last two bricks out, 3 cm per time, with this we get two tabs to finish closing the bell. We will use these tabs and the front wall of the fume duct to place the bricks as shown in the cutting plane above. If by this time it is not understood well do not worry because later the pictures will give you a clearer journey.

Undoubtedly one of the most important challenges of this brick stove is not to incorporate iron armor (rods) or concrete, even lower the Portland cement consumption as much as possible, as this will deteriorate quickly with heat, instead if using a large amount of hydrated lime for brick seating. This allowed us to substantially lower the costs of the work and assures us an ecological demolition.

Detail of the lung, seen from above before constructing the duct, in which we can see how the base of it tilts back forming an the object of which is that the remains of fall on this wall and can be cleaned by introducing a by the throat.

The photo above shows the work practically finished, we only have to connect the chimney pipe with the exterior and test the stove after the walls had dried enough, it is convenient not to force the drying and allow the humidity escape by evaporation of the own shot before using it intensively.

How to Build Brick Chimney

In winter, there is nothing more enjoyable than enjoying a good fire around the fireplace and as I am from town and I love the warmth of the fireplace we have decided to make one in the cottage.

As the house is very small inside, the chimney we will guide it all to the outside of the house, so that the interior does not occupy anything and even in the summer-spring season, when not used can be hidden.

Well, as I mentioned both the hood and the smoke pipe I have built them from the outside. We started raising the desired measures for the chimney which at first are 80 centimeters deep by 100 centimeters but then with the inner lining of refractory bricks these measures will be reduced.

Iron rods are placed on the base where the walls will be mounted to reinforce the start, although the base is already concrete and is a stable surface.

For the first row, bricks of different sizes are used to save the unevenness of the concrete floor.

Now we have the base level and it is easier to go placing the next rows of bricks. I have used bricks 7 centimeters thick forming a double wall with a small air chamber to avoid, as much as possible, the loss of heat and since the budget I have is not very high and I cannot use special materials too expensive.

We reach the desired height with the first brick wall, then the smoke pipe will take a pyramidal shape to the headboard or chimney cap.

The first brick wall is cemented to make it stronger, faster and cover possible holes.

The air chamber remaining between the two walls can be filled with expanded clay, for example, to increase the insulation.

The opening of the chimney is proceeded from the inside, so the debris will fall directly to the base and serve as a fill to increase to reach the desired level.

The area of ​​the fireplace that houses the fire is called “home”, is one of the fundamental parts of the chimney and therefore is very important the choice of materials to be made. In this case I have chosen refractory brick. It can also be; Refractory ceramics, cast iron or steel sheet. After we have paved the rubble we have covered them with dry gravel and then we have added another layer of concrete.

The mission of the bard 1 is to prevent the direct descent of the cold air, which weighs more than the hot one and therefore goes down and could produce smoke plasters into the interior of the house, which is why the bard 2 must of being below 1 and to the same perpendicular vertically speaking so that the cold air does not go down directly. In this way the cold air, let’s say it is entertaining and leaves the warm air that is produced in the “home” that goes up through the smoke ducts. To make this design I have based on the fireplace that I have at home that has a very similar system. I will try to put a video when I turn it on for the first time to see how the fumes come out.

The interior walls are covered with refractory brick 3 centimeters thick.

Once finished outside the “home” we are preparing to build what will be the chimney which in turn does the function of the smoke ducts, since the chimney does not have any metal tube to expel the fumes.

While in the interior, we are covering and finishing the edges of the walls with refractory brick.

Also in the fire zone are placed the refractory bricks.

Top between the fire zone and the front that is slightly higher than the inside.

Before plugging the chimney with the chimney, we will put insulating material on top of the bards to better withstand the heat, then proceed to cover the cork with a good layer of plaster so that there is no danger of burning.

We go with the elaboration of the bell. At the top of the roof we have helped two rods to place the wire, which will guide us, at the appropriate distance, that is, in order to leave, in this case, a smoke outlet of 30×30 centimeters more or less.

In the image you can get to appreciate the wires as they will help to form the bell in pyramidal form.

While the inside is already practically finished.

When it is completely in line with the wall, the chimney is a bit bland, as it does not have the typical wood over it nor some pillars on the sides. So we decided to decorate it a bit by placing a cement frame around it.

The desired contour is marked with a pencil and then the paint is bitten so that the cement grabs the wall.

It is filled with cement (a thickness of about 2 centimeters) around the contour, or to the eye, or we can help with slats of the desired thickness as a guide.

In the image you can see the thickness of the layer of cement applied to make the frame of the chimney.

If you do not like it to be just a straight line frame, you can help with some tool such as a knife, spoon, etc. to mold the cement.

In this case I carry a tool that is used in the plaster.

You have to work the cement when it is firm but before it completely shrinks.

This is the way more or less, failing to clean the remains of cement and re-paint the parts that previously had cement.

While, on the outside, we continue with the construction of the bell and placing the bricks with the proper inclination marked by the wires and the wall guides.

As I go up the rows of brick I am wearing plaster on the inside of the bell. Gypsum withstands heat better than cement.

I had to break part of the roof to continue with the chimney. Normally it is recommended that the chimney overhang the roof, as long as they are reasonable measures.

We have finished with the bell, it is time to start with the cap, cap or headboard, whose purpose is to facilitate the exit of fumes and prevent rainwater from entering. I have cut 110mm diameter pvc tubes and filled them with concrete to be used as pillars of this mini-roof. As a base I have used two pieces of porcelain left over from a friend.

Slopes are formed to place the slanted tile with a blown brick to prevent water from soaking the walls of the headboard.

The tiles are distributed and placed seated in cement they do not move .

This is the finished interior and a side view of the fireplace in which you can appreciate that it does not occupy space inside the dwelling.

Here are the photos of the bards from within. One of the bards is superimposed on the bards that start from the fire zone, maintaining a hole 10cm high by 90cm long for the smoke to rise upwards.

How to build an outdoor fireplace, step by step

Now that the cold seasons begin many of us start dreaming of chimneys, which serve to warm up, to create atmosphere, to cook … there is no doubt that both inside and outside the houses, chimneys are an important part of the homes that can afford them. There are chimneys that are bought ready-made and installed, but we can also make them by ourselves, especially outdoor ones.

An outdoor fireplace is ideal to enjoy more of the patio or the garden during the fall and winter, as it provides the necessary warmth to make the fresh atmosphere more pleasant. The construction of a chimney not as complicated as it may seem at first glance, is simple and can be done by following some basic rules, we will see how to build a simple fireplace in a few steps .

  1. The first thing is to choose the place where we want to place the fireplace, it must be away from things that can burn, cables and pipes, in the fireplace we are going to make fire, we must be very aware of this and always avoid the risk of fire.
  2. Once the place has been chosen, we clean it and mark the area, we can paint with chalk, for example, what the chimney will occupy, and then excavate a bit in that area and thus be able to place a solid base.
  3. Once the excavation in the ground, which does not have to be too deep, we must build the base , which can be made with cement or other resistant material, taking care that it is smooth and even in level.
  4. The following is the construction of the walls , we will make them with bricks, each brick should be placed next to another without leaving space between them, using high temperature resistant cement to join them together, we are placing rows of bricks, on them cement and more bricks and with the same cement we cover the holes that may remain.
  5. There are different ways for chimneys, if we want something simple we go directly to step 7, if we want the most conventional way, we should pay special attention to the front of the chimney. When building the walls in the front , we must leave an open space about two feet wide or so, depending on the size of the fireplace, that area must be covered with material of great resistance to fire, there are special bricks for that.
  6. Something fundamental in the traditional chimneys is also the exit of fumes, to solve it a pipe is inserted in the opening of the chimney in the superior part, when placing the bricks of the walls, we narrow the cabin, until we reach the upper part, the narrowest part in which we will fix the tube with cement, once the tube is fixed, we continue placing the bricks around it.
  7. Now, if we look for something simpler, we can forget the two previous steps to do something like what we see in the image of this article, a chimney of the simplest , its advantage is that it is easier to build and same time is just as functional as the others, but the smoke outlet is not as controlled, that is its drawback, here there is no front hole or tube to place, only walls with space in the center to place the wood and light the fire , on top of it you can place a grill if you want to cook over coals ..
  8. Once the structure is finished, in any of the cases, it is only necessary to decorate the exterior of the chimney to the taste, that is already a matter of the imagination of each one, for example, we can place some stone around, finally there is to take the wood, light the fire and check if the smoke outlet works properly.
  9. Finally, those who are not very handy, do not despair, if this seems too complicated or you are not for the work … I remind you that you can also buy the fireplace already made and simply limit to install it.

How to build a fireplace

There are many types of chimneys, but the ones that we associate universally with that name are the French chimneys. These chimneys require a complex masonry job that not everyone is able to tackle. Therefore we recommend that you consult a builder before undertaking this type of work if you do not have previous experience.

These chimneys are available in various sizes and formats, we can choose the one that best suits the room in which we are going to locate it.

We can use different materials to build the chimney: stone, slab or refractory brick, block, etc. These chimneys are regularized and their interior shape is not necessarily reflected on the outside, as the finish can hide the masonry behind wooden or plastered partitions.

Prefabricated draft regulators can be used, which are lined with refractory brick. At the top of the shot is a ledge that deflects the descending shots of the chimney.

When the exposed masonry is left, it is saved in finish and this allows to leave the brick wall completely seen. To harmonize, the remaining walls of the room will be revoked or covered, in this way the fireplace takes center stage.

How to make the fireplace:

First of all, we must define the location of the chimney, since its optimal functioning depends on it. It must be placed on a wall from which the heat is dispersed over as large a surface as possible.

If the chimney is located on an interior wall, we can also see the brick on the other side of the wall, creating a rustic decorative effect and also, the heat is better used.

For a French fireplace to function properly, the height of the fireplace opening must not exceed 84cm. It is usual to use prefabricated draft regulators with metallic grooves, which have better draft because they are smoother than those made of brick.

The smoke shelf of the draft regulator should be between 15 and 30cm deep with a smooth and concave surface. The chimney of the chimney should have a size according to the size of the chimney.

To build the chimney, we mark the area where it will be located on the ground and begin to place the bricks, forming the chimney box.

The floor is formed on a layer of refractory mortar, where the bricks or slabs are applied. It is possible to give it any shape you want. The placement of the floor is done from the outside inwards so that the cuts are at the bottom.

When the floor is dry, we lined the interior walls with refractory brick.

The extractor hood will be made with partition brick or tongue and groove. The wall of the hood is inclined at 45º and has a cone shape, up to the height where it connects with the chimney pipe. The hood is left to dry at least one day before applying the coating.

How to build a fireplace in the patio of the house

Thinking about a chimney when looking for a solution to counteract the cold during the winter season is an excellent option, since these in addition to maintaining the air conditioning inside the home perfectly, also comes to offer a striking style as this fills of beauty, elegance and originality to the space where it is installed, rapidly increasing its purchasing and aesthetic value.

Anyone can have a fireplace because they can even be made by the same people, mainly those directed to the patio or the garden, because they offer a much more pleasant fresh environment. To build one of these structures does not require much work or materials, the only thing that is required is to follow each of the steps that will allow creating a simple and at the same time beautiful outdoor fireplace.

The first step is the space where the chimney will be located, avoiding being near pipes, cables and things that may burn. After having the perfect space you should draw with a chalk the dimensions that the fireplace will occupy to take it as a reference when carrying out the excavations.

Subsequently the base must be built, for this you can make use of cement or a super resistant material, taking into account that it must be level and completely smooth. Then you must build the walls for it must use bricks, where each must be placed next to each other, the cement to be used must be very resistant, and must be at high temperature so that it can join each. The placement of the bricks should be in rows, where between one row and another should be placed cement and at the same time should be covering the gaps that may remain.

It should be made four walls that carry a space in the center, to decorate this structure you can use your imagination and interact with different materials such as decoration with stones that is spectacular.

How to build a construction chimney

When the house exists and you want to build a construction chimney, it will have to be located under a smoke outlet, shunt, that allows the smoke and carbon monoxide to go outside and that the outside oxygen enters to help combustion and that the indoor air is not contaminated, in the case that that smoke outlet does not exist, it will have to be located with the proper licenses and permits.

Resolved the location of the shunt, the draft of the chimney should have the appropriate section, proportional and calculated to the volume where combustion is going to be carried out and the length to be traversed until the exit of the gases and in addition the shunt should have a cusp that allows the air to come in clean and smoke out smoothly, so that it does not allow the dirty air to come back in through the draft and thus have a gas inhalation problem.

The fireplace can be installed free of wall or attached to it. The material with which the chimney forms must be refractory, that is to say that it supports the high temperatures that are formed and to which all the materials in contact are going to be submitted.

The materials usually have an RF card, usually come as RF-index, it will be a number that indicates the average fire resistance of the material or training in concrete, in minutes, for example RF-120. The hearth will be installed and over it the cladding and the hood, the rock wool will help to isolate the walls of the hood and then attach to the outside plasterboard plates, the joints will be treated and the whole chimney will form a perfect and unique composition. All the areas to which the chimney is attached should be perfectly insulated and conditioned for heat and fire.

The chimneys can be of open or closed home, the closed home is less romantic and aesthetic, but it is certainly safer and with greater calorific and distribution power.

Fundamentals for the construction of a fireplace

A fireplace is a nice addition for any home. It is an attractive center for a main hall and can add value to the house. The construction of a fireplace in the home is a great DIY project, and knowing the basics for its construction can save you time and money.


Find an ideal location for the fireplace in your house. If you are using generic plans for the construction of the fireplace make sure it will fit in the location you have chosen. Mark the place of the fireplace on the wall. You will have three main components: the home, the combustion chamber and the hood. The home protects the floor from the heat of the fire, the combustion chamber will surround the fire and the hood is a decorative piece that is built around the chimney.

Size of the fireplace

When taking initial measurements, it is essential that the depth of the chimney from front to back be two thirds of the height of the chimney. Therefore, a chimney that is 60 inches (152.4 cm) high must be 40 inches (101.6 cm) deep. This is to ensure that the smoke from the fire can be expelled through the flue, the pipe that carries the smoke outside the house. Make sure the area where the home will be located is level and check it constantly during construction.


Choose a hood design that complements the design of your home. There are many prefabricated homes that you can buy and you are free to make your own design. There are several styles that include rectangular openings, arched openings, corners (when a chimney is built in a corner and can be accessed from two sides), and a U-shaped opening, where the chimney is exposed on three sides. Choose the right hood for your design.

The Benefits of a Rustic Fireplace

There is nothing better than being cold and being able to curl up next to a fire with a good blanket and the company of loved ones. If you want to integrate a chimney into the decoration of your home, do not hesitate to do so because the warmth and the feeling of well-being that they bring will be unmatched.

In addition to these two advantages is a heat source allowing you to use natural heat in addition to the radiators in the room that you install. To ensure heat for a few hours or days, you will need a place to leave logs or coal next to the fireplace so you don’t have to go outside to find material to source the heat.

Enhancing a room with chimneys therefore has an endless number of advantages. A rustic type is a decorative option depending on the style of your house. In rural homes or those located in the mountains this choice is the perfect solution. In addition, you can make the chimney the size you want and with features to your liking.

You must install a protective glass to prevent the flames from going outside. This glass will be of a special type that does not allow the material to overheat avoiding contact burns. In addition, it allows to remove the heat in such a way to create a pleasant and well-heated room.
