For some reason, believe that the chimney – it is just a pvc pipe fitting or a pex pipe. But first, this pipe must be connected to the exit flue pipe stove (fireplace, tankless water heaters). Suddenly it turns out that it is directed horizontally. Immediately there is a problem changing the direction of the chimney: we need something vertical. Here come to the aid of a knee or tees. (At the tee, in contrast to the knee, if it provides an element of cleaning – removable cup at the bottom or any other element of the audit – just easier to clean the flue channel.)
Let’s tee found a pipe. But they also need co-members among themselves. And not just as tightly, so that the smoke does not take place at the junction. Therefore, they should just come together.
Go ahead. Suppose the chimney must pass through the second floor. But the pot is set so that the exit flue channel prevents some beam. It must be circumvented. Again the need to change the direction of the chimney. Easy! There is a knee at different angles of rotation, such as the knee angle of 45 °. They turned the smoke channel, skirted the obstacle to continue. Or here it is, the overlap of the second floor – wood! How through him to the pipe, which roam the hot flue gases? After all, maybe to flash. To do this, there are special bushing tubes of greater diameter. Cut a hole in the ceiling, put a tube passage, isolate and carry out the chimney. And to pass on the second floor and exit to the roof, take the next pass pipe. But even at the desired angle. Just keep in mind that the purpose of fire safety in places of passage through the ceiling of his chimney pipe must not have joints with the other pipe. If it turns out that the standard pipes are not allow to pass this place without the dock, do not worry. All thought! The set of modular chimney pipe must be smaller length. For example, a length of 1 m, and 50 or 25 cm first becoming a short tube, and then with a long tube quietly pass overlap.And do not forget that the chimney needs a skilled care. At least twice per heating season should be the cleaning. And now we present excerpts from building codes to the flue (DBN V.2.5-20 2001 “???????? ?????????? normalization of Canada”):
# The combustion gases from domestic gas devices, furnaces and other gas equipment, construction which provides combustion gases up the chimney should be carried out on each device, unit or furnace to a separate channel (chimney). Existing homes are allowed to join a chimney is not more than two water heaters or heating furnaces located in the same or different floors of the house, provided the input of the combustion products up the chimney at different levels, not closer than 0,5 m apart.
# Non-adherence to the flue heating device, which does not operate continuously at a sufficient section of the chimney, which is determined by calculations.
