The types of chimneys and their features
Chimney for the bath there are two types - external and internal. The advantage of an external chimney is safety by reducing the risk of fire. This chimney is easy to mount their own hands and fix. The main disadvantage of constructions - heat losses due to the release pipe outside.
The internal arrangement is more dangerous - it increases the risk of fire and has a complex device. In this case, all of the heat is concentrated in the bath due to the lack of contact with the street. Internal chimney is the preferred option for those who do not want to spend large sums for heating
The structure of the chimney
The chimney comprises a number of nodes, each of which has its own task. chimney design depends on the furnace, which is used in the bath. To include the following main components:
- headroom (does not spark falls on the roof and prevents flooding of drainage in the rain);
- Flash Wizard seal;
- double pipe insulation;
- Ceiling assembly;
- iron pipe.
Masonry structures require frequent cleaning and maintenance.
Construction of the so-called "Sandwich" tubes are easier to handle and assemble. They are double-tubes with the insulating layer in the form of asbestos. The advantages of the sandwich include energy efficiency and ease.
Laying chimney
Installation of the pipeline consists of three main stages:
- The preform holes to remove the tube;
- Attaching a security box;
- Mounting the chimney.
holes billet
When laying pipes inside the bath is done holes in the ceiling or in the roof construction. Exterior chimney requires one hole - in the wall next to the stove. Designated openings are sheathed by metal sheets (thickness: about 0.5 mm). Sheets are responsible for fire safety. The holes have a square cross-section area 4,5h4,5 centimeters.
Production crashbox
Protective box plays an adapter function for the conduit. When you create a box you need to follow this procedure:
1. take the two metal sheets and cut them in the hole for the pipes in the middle;
2. do box of four sheets such as by welding;
3. warm box using mineral wool from basalt and covered with a layer of metal foil;
4. attached to the roof of the protective metal apron (sold as a finished product);
5. set transitions between the ceiling box and fasten it with screws.
The box is only required for the "sandwich" tubes. Brick chimney construction is not necessary, as they heat up more slowly.
installation of chimney
Installing an internal chimney involves the following procedure:
1. piercing sites for attachment of the pipe;
2. attaching 1st level from furnace 50 centimeters in length to the wall by means of metal fasteners;
3. removal of the 2nd level to the metal box (if the oven is not positioned under the ceiling hole, you need to use the knee);
4. falling asleep expanded clay boxes;
5. assembling the fungus in the upper part of the tube (fungus can be bought ready to do his or sheet metal and tin).
The outer chimney is going on a similar technique, but with the only difference - in the first place to Install the knee wall. Then, the basic construction is established.
