Finally we need to communicate the chimney flue with the outside but first let’s review some parts of this manual:
Construction of the base: Explain how the coil chamber is built to take advantage of the heat of the home’s floor
Construction of the reflecting walls and Lung: These are the ones that give form to the combustion chamber and serve to reflect the radiation of the flames to the outside of the mouth.
Installation of the oven and bell closing: Here the lung was closed by means of a bell and on the
The same oven was installed that will serve in this example for the smoking of porcine products Identification of shooting problems: This is an annex which has a video describing how to solve problems of excessive or inefficient shooting, for the latter it is advisable to raise the shot or the installation of a weather vane.
Finally in this manual we will give construction of the smoke flue and provide a plan of measures of the stove, but this is only for guidance, our desire is not for the user to build a replica as is, so we give measurement relationships and suggestions and possible defects to be taken into account, in any case the plan as it was built this barbecue chimney contains the measurements and has been proven by identifying a defect of excessive draft, for which a record or valve of shot will be installed also known as balance.
In the above image, the oven can be seen, which is optionally constructed and the mouth of the oven can be closed with bricks located on the edge. Now the construction of the pipeline that will transport the combustion gases is not complicated, you only need to raise the 33 x 33 cm square to the ceiling.
They may choose other ways to take the duct outside, in this case we prefer the straightway, and it is to cross the earthenware or roof plate as is the case directly on the duct.
When we have a second plant or a complex fall, this is that if we make the hole could be at risk of large water leaks, we will choose to install an elbow and take the exit by the wall instead of the roof. In our case the slope of the roof is 7% and long to the chimney of 2.5 meters, although there may be a risk that the chimney represents rainwater and occasional leak, we expect that the zinc plate we cut has no joints, then we crossed the same medium of the sheet of 1.10 meters generating a hole of 33 x 33 we left enough space for the water to evacuate the sides.
At the time we lift the pipe we will the inside and outside this will allow us in the future a comfortable cleaning of the soot, because like any stove is very advisable to call the chimney sweep before the winter period begins, fire may occur in the shot if this It contains a lot of carbon crust adhering.
To prevent the water from entering the interior, in metal ceilings the sheet is bent as shown in the drawing in such a way that it acts as a dam. In this way, before falling inward, it discards the channels towards the ends. To cut the hole we use an angle grinder without removing the sheet from the ceiling, but keep in mind that it must coincide perfectly with the rise of the shot. To mark the edges of the square we drill with drill from below, helping with a level so that the hole serves as a guide for where to cut.
When the roof is made of concrete, we will proceed in the same way, marking with a drill and making a cut in the lower part of the tile with grinder and Widia disc. in the center, where the conduit will pass, we will make a hole with a drill, and then from the roof with allude of a short cold and we will enlarge the first hole created by the drill hole. We will leave the cut of the earthenware irons for the end, for safety reasons.
To elevate the pipe to lead with the help of a lapis we will draw its contour on the wall and this will serve as a guide, as usual we will the exterior while growing the courses, as seen in the part where the sky created a brick flange, this is to hide the juncture of same with the chimney and we avoid the installation of joint or half pipe, because the plaster sheet supports the eyelash that remains in sight.
The upper part seems very obvious to dealer, because it consists of elevating the pipe to the outside and it is completely different for each roof, vastly recommended to exceed 70 cm any wall or parapet that could repair the perfect evacuation of gases of combustion, in this installation metal stoves are better explained.
