Regardless of the selected chimney species, it will includein its membership the following components:

  • pipe for exhaust fumes;
  • pass tube;
  • adapter to connect the chimney to the spigot of the boiler;
  • clamps and mounting brackets;
  • telescopic tube;
  • tee with hose for the condensate drain;
  • challenges;
  • tip in the form of a cone.

different materials can be used for the manufacture of chimney.Check out the features of the most common solutions and make your choice.

Judged objectively, the chimney of the brick it's not even past, and the century before last.Such fume collection system has a complicated structure and requires significant time, labor and financial costs for the resettlement.

addition, the chimney of the brick will give way to a modern "fellows" for a variety of relevant indicators.

Design "sandwich" type of pipe is considered one of the most effective and appropriate ones fume collection devices.

Today, manufacturers offer a huge range of chimneys.Among their advantages is necessary, first of all, mention resistance to abrasion and various mechanical stresses.

Directly "sandwich" has a very simple structure.It consists of two differing diameter pipes, one inserted into the other.To fill the gap between these pipes most commonly used non-flammable basalt wool.

modern version with excellent performance and presentable design.It is made on a "pipe in pipe".Designed for use with gas-fired boilers, combustion chamber which is made on the closed type.In this type of equipment for gas combustion air intake is taken from the street, not from the heated room.

The principle of the coaxial chimney

The principle of coaxial flue

air supply is carried out by an external pipe laid through the outer wall of the structure.Smoke with impurities derived through the inner tube.Such an apparatus is advantageous by the fact that it eliminates the need for additional installation of the ventilation system.

In addition, a specific form of coaxial chimney eliminates the possibility of condensation on its walls, which is particularly important in heating systems, which operate on gas fuel.

Ceramic chimney

Ceramic chimney

It is a reliable, simple, fireproof, easy to install and affordable design.Its structure is extremely simple.This chimney is a ceramic tube wrapped with insulation material (usually mineral wool) and placed in a sheath of expanded clay.

Regardless of the selected chimney varieties, improvement of the design must comply with a number of important requirements.

requirements fume collection design

Recommended placement options chimney

  1. maximum allowable slope areas dymotvodyaschey design - 30 degrees.
  2. length of branches in the parties can not exceed 100 cm.
  3. fume collection system should be made without ledges.
  4. cross-sections are excluded.
  5. Max knees - 3.
  6. Allowable radius - not less than the diameter of the pipe used to drain the smoke.
  7. On turns you need to install the auditing hatch to clear the condensation fluids and cleaning systems.
  8. If the chimney is constructed of rectangular shape, the width of one side should not exceed the width of the second 2-fold, ie,it is impossible that the article has been stretched look.
  9. the bottom of the tube is necessary to arrange drip and audit.
  10. not allowed even insignificant deflections of structural elements.
  11. When building the chimney one link design should be worn for a second at least 0.5 pipe diameter.
  12. presence of gaps between the structural elements under a ban.
  13. in sections passing chimney walls and ceilings can be no joints.
  14. combination of all elements of the system should be as dense as possible.
  15. The minimum slope of the fume collection tube in the direction of the heater - 0.01 degrees.
  16. inner walls of the pipe should be as smooth, rough, highly undesirable.
  17. total length of the horizontal portion of the chimney can not be more than 300 cm for construction of houses and 600 cm for the erection of buildings.
  18. Minimum distance between the tube and the surfaces of the combustible materials - 250 mm, non-flammable - 50 mm.
  19. At the intersections chimney walls and ceilings need to make quality insulation.

    The height of the chimney to a gas boiler

    height of the chimney to a gas boiler

Special attention is given to the requirements height fume collection tube with respect to the ridge of the roof structure.Thus, the chimney should be moved outside the site of the wind backwater and mounted at such a height:

  • if the horizontal separation from the ridge exceeds 300 cm - above the imaginary line drawn down from the roof ridge to the horizon under desyatigradusny bias;
  • if the chimney is removed from the ridge at 150-300 cm - on a single level with the ridge;
  • if the horizontal distancing does not exceed 150 cm - not less than two feet from the ridge of the roof.

chimney must rise above the adjacent portion of the roof of at least 50 cm. If the roof is flat (combined), this figure should be increased to 200 cm.

distance from the ridge to the chimney, m height of the chimney to a gas boilerwith respect to the ridge, m
Up to 1,5 0,5
1,5-3 level
& gt; 3 holding an imaginary line at an angle of 10 degrees to the horizontal bottom, on a par with that line

How to install the chimney sandwich

order of arrangement of the chimney will be considered by the example of sandwich constructionssystem of pipes.This is the most optimal and flexible solution.There are 2 methods of assembling such a structure: in the house and outside.Explore both options and choose the right.

sixth step. Building up the chimney by connecting new units to achieve the desired length.Calling the planned height, set on the tube tip is conical.It will protect the system from rain and wind.To fix the pipe to the wall structure using the brackets.Step placement of fixing elements must not be less than 200 cm.

seventh step. strengthens all joints structure with clamps.Contractible their wire or bolts.

eighth step. stained chimney special heat-resistant paint composition.It will provide adequate protection against rust material.

begins with preparation:

  • envisage in the ceiling and the roof openings for pipes;
  • checking the labels with dimensions of pipe, making an opening for the chimney.

Next deal directly with the chimney installation.

first step .Connect the adapter to the transition conduit unit.

second step. Install a tee and an audit.

third step. start to build up the chimney.

carry out the work if necessary with the use of so-calledknees.At the intersections of overlapping tube use special protective tube.

fourth step. puts on a sheet of stainless steel chimney.Pre hole in the sheet is cut slightly longer than the diameter of the pipe.This list must be on both sides of each slab.

Insulation fume collection design

At the points of contact elements of the fume collection pipes with flammable materials necessary to build a reliable thermal insulation.To ensure it cover the entrance pipe basalt wool with a foiled layer.Fixing the insulation is performed using fire resistant mastic.Additionally Lay the mineral wool around the perimeter of each opening in the partitions and ceilings.

At the end of installation actions always check the tightness of the system each seam.For this enough to put on the seams of a simple soap solution.The appearance of bubbles indicates the tightness of the system.Correct any problems found in the shortest possible time.
