range hoods are familiar to everyone, and they are often used in life. When installing a range hood, the exhaust pipe is indispensable, because the householder who doesn't know much about the installation doesn't know how to do it. So what should we pay attention to when installing the flue of the range hood? Let's take a look at the installation method and installation precautions of the flue of the range hood with everyone!

installation method of flue of range hood

1. Installation requirements of exhaust pipe of range hood: the distance from the exhaust outlet to the machine body should not be too long, and the turning radius should be as large as possible with few turns, otherwise the smoke exhaust effect will be affected. The smoke exhaust pipe extends out of the outdoor or into the cold air suction flue, and the interface should be tight, so there is no need to discharge the exhaust gas into the hot flue.

2. Fixing the hose of the range hood is actually not so complicated. We only need a few steps to install the hose of the range hood, and we will not have the phenomenon of backward wind if we bend it at a 91-degree angle. However, in general, the air outlet is drilled with a hole of 111, and it is best to pull it out with a hard pipe of 111, then install it outside the wall with a 91-degree elbow, and finally use a large and small head inside to convert and fix the hose.

3. If your house itself is designed with an exhaust pipe, you don't have to worry about the problem of downdraft. The real estate developer has considered it when designing. Just put the exhaust pipe in the pre-designed exhaust pipe, and then let the carpenter on the ceiling try to fix it.

4. The distance from the exhaust outlet to the machine body should not be too long, and the turning radius should be as large as possible with few turns, otherwise the smoke exhaust effect will be affected. The smoke exhaust pipe extends out of the outdoor or into the cold air suction flue, and the interface should be tight, so there is no need to discharge the exhaust gas into the hot flue. The air outlet pipe should not be too long, preferably not more than 2 meters, and the bending should be reduced as much as possible to avoid multiple 91-degree bends, otherwise it will affect the oil smoke absorption effect.

5. Fixing the hose of the range hood is actually not so complicated. We only need a few steps to install the hose of the range hood, and we will not have the phenomenon of backward wind if we bend it at a 91-degree angle.

Precautions for installation of fume hood flue

1. After fixing the fume hood hose, we need to know about the installation of the fume hood hose. Let's introduce the installation of the fume hood hose. First, insert one end of the smoke exhaust pipe of the range hood into the notch between the inner and outer rings of the check valve outlet, and then fasten it with screws. The other end of that range hood directly extend into the outdoor through the reserved hole.

2. If the smoke exhaust pipe of the range hood leads into the public flue, it must be connected with the smoke return check valve of the public flue and sealed. If the smoke is discharged to the outside of the wall, it is suggested to install blinds outside the smoke exhaust pipe to avoid reinjection. If the smoke exhaust pipe of the range hood goes to the flue, do not insert the smoke exhaust pipe too deep to increase the smoke exhaust resistance. If it leads to the outside, make sure that the smoke exhaust nozzle protrudes 75px.

3. The exhaust pipe of the range hood should not be too long, preferably not more than 2 meters, and the bending should be minimized to avoid multiple 91-degree bends, otherwise it will affect the oil smoke absorption effect. The exhaust pipe extends out of the outdoor or into the public cold air suction flue, and the interface should be tight, and it is not allowed to discharge the exhaust gas into the hot flue.

when installing the exhaust pipe of the range hood, many details need to be considered by everyone. Of course, how to install it correctly also needs to be known by everyone. The above is the installation method and installation precautions of the flue of the range hood introduced by Xiaobian, which ends here.
