We determine the place to conclude the pipe through the roof

How to withdraw the pipe through the roof - Turn-based action

Given the basic rules of the device chimney system, the exhaust pipe, installed on the roof should be as close to the junction of two roofs rays.Right on the "ridge" can not mount a conclusion, since the beam is nesushey roof structure and the interference is unacceptable in terms of strength.But the pipe height can be any, the main thing - to 50cm above the upper line of the arch.

To flue pipe, installed on the roof of the house for a long time served and did not spoil the overall look of the house, you must take the following steps:

• correctly identify the place of exit of the pipe through the roof;
• spend preparing the roof frame;
• make a hole in the roof of the required diameter;
• install pipe;
• insulated chimney out of the roof the roof.

For the definition of the place for the outlet pipe from the roof we have said before, so the order will be examined with the following steps.

Preparing roof frame

Without prejudice to the design of the roof frame is not enough.Step by step perform the following steps:

• from one closest to the exit point of the rafters, at a distance of 50cm diameter of the pipe plus, install another parallel to the original, truss leg.
• using plumb project the rafters in the attic floor, he measured one and a half meters from the perpendicular, define the place where the pipe will be in the center;
• from a central point back down a distance equal to the radius of the chimney plus 25 cm, and at this point, set the upper beam, perpendicular Roof coverings.;
• likewise to locate the bottom of the beam

box for the pipe on the roof, additional set of roof beams, chimney must be greater than the diameter of 50 cm. Follow the rules of fire safety rules, directly abutting the surface of the chimney to the roof, it is strictly prohibited.

drill a hole in the roof

After installing the boxes need to make a hole in it for passage of the pipe through the roof the roof.For this purpose, at the four corners through drill holes on the perimeter established by the beams.Next, we determine the output side of the border with the vernal roof on the square of the drilled holes.Now, the roof can be opened in order to remove part of it.This operation can be done in two ways:

• first - using the grinder or jigsaw to cut the inner perimeter of the box;
• second - to carry out the cuts diagonally.

Selection process for the removal of the roof depends on the material being cut.

Install pipe on the roof

proceed to the installation itself chimney After the cut roofing material:

• turn down outside the outer layer of the roof and insulation - inside the box and fasten it to the beams;
• inserted into the resulting hole chimney from the attic, and fasten it to the "baffle";
• on the surface of the pipe is applied a heat-insulating material layer and fix the screws on the clamps;
• from the attic of the box cover with asbestos or metal sheet and fall asleep in it a non-combustible insulation, such as expanded clay.

Sealing To seal the abutting pipe to the roof, use the kit already assembled for this work.On the external part of the chimney cap is put on, which is called "apron", and secured to the roof on the screws.For chimneys round and square form "apron" is also different.Node abutting the roof to the tube sealed using heat-resistant sealant.
