Chimney spark arrestor installed

Also, it can be difficult when a part seems to do the same function as another part. Then you realize it ends up being called another name.

Learning what each individual part actually does makes it much easier to see the importance of each part. You can also see the functions that make parts different from each other. Many people tend to confuse chimney caps with spark arrestors. This is because they both sit on top of the chimney. However, not all chimney caps are equipped with the mesh metal siding that spark arrestors must have.

So now we would like to explain the differences to you. Spark arrestors keep sparks and embers from landing on the roof or on combustible material on the ground to start a fire. Chimney spark arrestors generally consist of double layers of metal mesh. This mesh can catch embers, yet still allow gases and smoke to exit the chimney.

See What is the purpose of a Spark Arrestor. The metal meshing on a chimney spark arrestor is great to prevent birds, squirrels, raccoons, and other wild animals from being able to get into the chimney to nest.

Without this type of protection on your chimney, these critters can enter your flue to cause problems in your chimney and could even become trapped.

A chimney cap covers the top of the flue. This is to keep water from rain, ice, and snow out of your home. The Chimney Safety Institute of America recommends it as the most economical way of preventing chimney water leaks. A standard chimney cap typically does not have mesh metal sides.

This relationship is described in the table below. The principle of operation of such a device as a spark catcher is quite simple. Moreover, absolutely all varieties of these devices for chimneys work the same way:. The spark arrester can be of any kind, but all types of devices operate equally. If necessary, you can always buy a ready-made device and mount it on a chimney, however, many owners are accustomed to independently improve their home.

Making a spark catcher yourself is very simple:. The simplest option that can be made at home is the device represented by a plug for a pipe with holes drilled in it. It is worth remembering that if you decide to make such a spark arrester, you must first take care of choosing the diameter of the plug.

The plug, from which the spark catcher will be made in the future, must have a cross section greater than the diameter of the chimney. This is necessary in order to be able to put such a simple device on a chimney without special problems. The implementation of such a device is not difficult, however, there are some difficulties that are associated with the size and number of holes in the plug.

Incorrect calculation of these indicators can lead to a decrease in draft in the structure. In addition, there is one more minus of using such a cylindrical device - during operation it is covered with soot, resulting in an unpleasant odor from the furnace.

If sparks in the chimney occur too often or in large quantities, you should pay attention to its draft. If the thrust is too strong, it is worth reducing it, then this problem should disappear. The second simple option that can replace a full-fledged spark arrestor is a metal mesh, which is fixed with a special clamp on a chimney.

The disadvantages of this product include:. When making a spark arrestor with your own hands, you should choose a dome shape, such a device will be effective. Mounting a dome-shaped grid at the end of the chimney. The domed mesh is considered the most effective device among alternatives to high-grade spark catchers. In order to assemble a spark arrester on a chimney pipe at home, you will need the following list of tools:. For the manufacture of this device, it is recommended to select steel that has anti-corrosion properties.

The thickness of the wire rods should be as small as possible. The smaller the thickness of the rods, the longer it takes for the network to clog with soot. Tap them on the grid - this will relieve stress from the metal and it can be bent without any problems. The thickness of the rods for the spark arrester mesh must be at least 1 mm. For the correct installation of such a device, the dimensions of its cross section must be selected in accordance with the same indicator of the chimney.

The easiest way to install a spark arrestor is to insert it inside the chimney without any additional fasteners. However, this method is not particularly reliable.

The operation of the spark arrester requires regular preventive cleaning of its mesh from soot, so it is installed in such a way that the device can be easily removed at any time. It is strictly forbidden to weld the device to the chimney - the structure must in all cases be removable. Even if your roof is made of non-combustible materials, there is a danger that sparks flying out of the chimney will fall on objects and buildings that are located in your yard and ignite them.

Therefore, the installation of a spark arrester is recommended in all cases without exception. Stainless steel corrugation for the installation of the chimney: rules for selection and installation.
