How to install the range hood-how to fix the range hood tube

Fixing the range hood hose is actually not that complicated. We only need a few steps to install and install the range hood hose, and we have to bend down at a 91-degree angle so that there will be no backward wind phenomenon; 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.

If your house is designed with an exhaust pipe, you don't have to worry about the problem of downdraft. Real estate developers have 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.

How to install the range hood-how to install the range hood tube

Installation method: insert one end of the smoke exhaust tube into the notch between the inner and outer rings of the check valve outlet and fasten it with screws. The other end directly extends into the outdoor through the reserved hole. If the smoke exhaust pipe is connected to 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. Smoke exhaust pipes are generally 15 cm and 18 cm in diameter, but now the market is popular with 15 cm. It's convenient to keep the hole small and then expand it. It's not difficult to make it smaller when it's big, but it's easy to smell if it's not well sealed.

note: if the smoke is discharged to the flue for * * *, 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. The smoke exhaust pipe extends out of the outdoor or into the public cold air suction flue, and the interface should be tight. It is not allowed to discharge the exhaust gas into the hot flue. The shorter the pipe of the range hood, the better. If the pipe is pulled longer, after the range hood is turned off, there will be a lot of oil fume in the pipe that can't be discharged and then poured back indoors.

the installation requirements of the smoke exhaust pipe require that 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.
