Installation of stainless steel chimneys

Chimneys stainless steel are best suited for setting their own hands.For this work to handle even the ignorant in the furnace actually a man, as all that was required of him - ready to connect the components of the design by the designer type.Of course, there is in this case some of the nuances that affect the efficiency and durability of pipes.In this article, you'll learn all about how to properly collect the chimneys made of stainless steel with their hands.

design features

stainless steel flues are shorter and the second name - "sandwich chimneys."Just as in the case of sandwich panels is the name due to the peculiarities construction pipes - they are made of several layers.The inner layer is made of stainless steel, so that condensate arising during operation of the furnace or boiler, the pipe is not destroyed prematurely.Behind it is warmer, not allowing the smoke to cool down too quickly (when hot smoke sharply to face the cold outside air, condensation occurs).As thermal insulation typically use basalt incombustible material (mineral wool).The outer layer is made of stainless or galvanized steel (budget embodiment) which imparts structural strength.

Such a device makes it possible to successfully maximize output flue gases and soot, because the inner layer of stainless steel endures extreme temperature changes, and its smooth surface does not retain the soot particles.The latter is very pleasant to those who decided to replace the brick chimney steel - it will have to be cleaned much less often.

Advantages of stainless steel chimney:

1. Can be installed at any time of the year.
2. elementary operation and maintenance - as the inner loop does not contribute to the accumulation of carbon, enough to clean the chimney once a year.
3. In case of failure of any segment, there is no need to dismantle the entire structure - you can disconnect and replace a faulty section.
4. Due to the low weight of the chimney does not require the construction of additional foundation under the stove, in the case of brick products.
5. There are variants of chimneys for all types of fuel: coal, wood, gas, oil.By installing one or another form, should know that it will most effectively remove smoke only in the case of a furnace firebox suitable raw material.
6. To produce contours in metal alloy, titanium is often added for strength.In commercially available heat-resistant tube with a wall thickness of 1 mm that can withstand temperatures up to 600C.
7. Durability design is determined by its quality.Good stainless steel pipe for the chimney will last 20-30 years.

course, one pipe for installation is not enough - need a lot of hardware and fasteners (brackets, auditing, adapters, tees, elbows, collars, rosette, etc.).More details about the structure of the stainless steel chimneys and installation described in the video below:

upper part of the chimney must necessarily be tapered and have a spark arrester, voppler termogribok or at least to protect the roof from the fire, and that precipitation does not get inside.Insulation sandwich chimney allows you to display them on an external wall of the building, but if you can, it is better to skip it inside the house to reduce heat loss.

Types of metal chimneys

Going into the hardware store, you will see several varieties of chimneys.They are not only cost, but also the structure and purpose.The above products have two walls, between which a heater.These pipes are suitable for installation in fireplaces, boilers, gas appliances and stoves.

are also available and inexpensive single-wall pipe.In them there is no heater, so about any insulating ability can be no question.These products are intended for the repair of a segment of metal chimney, create connections in brick chimneys and structural reinforcement.

There is a third view - the most expensive.Coaxial pipe appeared on the market relatively recently and immediately demonstrated its effectiveness.They have an unusual structure - the pipe of larger diameter pipe placed less.After one out smoke from the furnace through the other enters into the fresh air and maintains intense burning.Coaxial flues allow you to do more than stand-alone heaters and are used in cases when the combustion fuel is needed a constant supply of oxygen.

pipe joining method

to connect the chimney sandwich of stainless steel using standard parts, however mounting methods may vary depending on the desired result.

There are two methods of docking elements of the chimney sandwich:

1. As smoke - this method guarantees the protection of the interior of the house against the penetration of carbon monoxide.It is often used when installing heating equipment in the bath or a residential building.It is important to insulate all joints quality, otherwise condensation will soak the insulation.
2. condensate - this technique allows you to create the conditions under which formed due to the extreme temperatures condensate directionally flowed through the pipe down.With this method of assembly of the upper segment of the inner tube lead into the lower socket, and the resulting water flowing from above can not hurt a heater.However, the smoke can get into the house, if there is at least one small opening.

In the first case, the chimney may be affected by condensation, in the second - there is a risk of carbon monoxide poison gas, so what do you choose?If you build the chimney inside the house, it is better to give preference to the method of "the smoke" if in the back room - "Condensate".However, in both cases, pay special attention to sealing of seams.

Installing chimney

Dimensions chimney made of stainless steel depends on the size of the building and the required traction.The standard length of one segment may be 50 cm or 100 cm. Installation of the stove start from the bottom and gradually move up, inserting one element to another.However, many experts recommend exactly the opposite effect - to collect the chimney from the top down, starting with the roof.This will in the event of failure to disassemble the entire structure, and easy to remove the defective part and replace it with a new one.

Each segment has a narrowed end - it should go into the wide end of the following items.All units must be installed so that accumulates on the walls of the condensate can freely flow down and does not linger in the joints.

Useful trick: two pipes to connect quality, pull the inner loop one of them is 15 cm, then paste it into another tube, and then fasten the outer contours.Each promazhte joint sealant and strengthen a steel clamp.The sealant should be special - the usual simply will finish off the heat as soon as the furnace.

How to bring out the chimney

first step in the derivation of the chimney to the outside wall of the building should take care of its stability.Sudden gusts of wind, hail or accidental shock can be fatal trouble, threatening to leave the house without heat.To avoid this, the chimney should be securely fastened.To do this, use a variety of mounting brackets, which are fixed to the wall of the chimney every 1.5-2 m.

If the design involves the installation of a tee or eviction, these details should also be attached to the wall.They will keep the chimney vertically, will not allow its collapse and will remove some of the load from the connecting elements.At the same time between the chimney and the wall must withstand a short distance - otstupok.To calculate the value of otstupka, you must take into account the thickness of the wall of the heating equipment, the nature of the furnace (open / closed), the degree of flammability decorative materials walls.Here's an example: let's say, the thickness of the walls of the oven with a closed combustion chamber is 65 mm, and it is exposed to the outside wall of fire.In this case, the safe distance is equal to a minimum of 50 cm. If the oven has thicker walls, for example, 120 mm and stands near the brick non-incendive wall indentation can be reduced by up to 20 cm.

If you need to install the chimney inside the boxor between two walls, on the outside of the wall should be done two window openings of 150 cm².One window should be located on the ground floor, the other - closer to roof.

floors Passage

If you run the chimney inside the house, sooner or later you hit the ceiling between floors.How to be in this case?To bring out the pipe through the ceiling, you need to make a special box with a hole in the middle.In this box, insert the pipe diameter slightly larger diameter of the chimney.The thickness of the box should exceed the slab thickness is 7 cm on each side.

The main purpose of this box - overlapping protection against ignition.During operation of the furnace chimney it can become hot to 100C and more, creating a fire hazard, so you definitely need to be insulated.The box must be carefully secured in the ceiling and connected with the pipe.Socket inside must be intact (without joints, different from the temperature extremes they disperse quickly).

When you set the box in the ceiling, pipe must be qualitatively isolate.It is better to use a special mineral wool mats with a foiled coating that reflects heat.These mats are covered with refractory mastic and are not afraid of high temperatures.The hole in the roof does not hurt paved with such mats for reliability.

Removing the chimney on the roof

So installing a chimney made of stainless steel is nearing completion, but there is still a very important point - the removal of the pipe on the roof.This can be done using a special link - cutting of roof.Cutting should be selected in accordance with the angle of the roof ramps.

How is the removal of the chimney:

1. Using a marker make the marks on the inner surface of the roof.The diameter of the future holes should be slightly larger than the diameter chimney (a few millimeters).
2. Cut through the hole in the roof, alternately cutting through and removing each layer of roofing pie.Do not even try to cut all in one fell swoop - the result will not be happy.
3. Inside the hole, place a steel pipe to insulate roofing layers.
4. Inside to attach the roof of the steel sheet with a hole for the chimney in the middle.
5. Output pipe to the outside and set on top of roof butchering.
6. mount on top of cutting the required number of units.
7. At the very end, attach an umbrella or a spark arrester to protect the pipe from the rain and the roof - from the fire.

Important: Where pipe passes inside the roof of cake, should not be the joints!

Useful tips

Chimneys stainless steel are the new generation of the product and successfully replace the massive brick structure.And though they sometimes cost more than the price of the installation even ceramic chimney, the benefit becomes noticeable after a few months of operation.For example, steel chimneys need to be cleaned less often and less broken, and if it happens, you can just buy a new segment and replace it quickly, without dismantling the entire riser.

And to use the chimney was even longer and more comfortable, we have prepared some useful tips:

1. When it is time to clean the go ahead from the top, after making sure that the flue is not blocked (bird could over the summer twist in it's nest,attacking leaves, etc.).
2. If the chimney is clogged anything, do not try to remove the blockage, and simply push it to the nearest of the audit.Audit - a special mounting elements are mounted in several locations along the entire length of the chimney.They accumulate debris falling from above.Before cleaning all revisions must be closed.
3. soot buy a special brush whose diameter should be slightly larger than the diameter of the chimney.Ruff work first, and when the soot settles, clean audit tanks.
4. To clean the chimney as rarely as possible, try not to use the stove softwood.It contains resins which are deposited on the inside walls of the pipes and form stubborn dirt.The same thing happens if the stove to heat the raw wood.
5. is not recommended to burn in the "home" of the furnace household garbage - use for this old metal barrel on the street.
6. To prevent occasionally throw in a little aspen wood stove - burned quickly, they provide a powerful high flame burns soot inside the chimney.

Installation of stainless steel chimneys is not so difficult, if correct pick up a tube and know how to handle them.Use the tips in this article and all you get!
