How to install a range hood - how to fix the range hood pipe

Fixing the range hood hose is actually not that complicated. We only need a few steps to install it. We need to bend the hood hose down at a 90-degree angle to avoid backdraft; however, the exhaust vents are generally drilled with 110 holes. It is best to use a 110 hard pipe to pull it out and then Use a 90-degree elbow to install it on the outside of the wall, and finally use a small and large head inside to switch and fix the hose.

If your house is designed with an exhaust pipe, you don’t have to worry about the backdraft problem. The real estate developer has already considered it during the design. You just need to put the air pipe into the pre-designed exhaust pipe. That's it, then just let the carpenter on the ceiling find a way to fix it.

How to install a range hood - how to install a range hood pipe

To install, insert one end of the exhaust pipe into the inner and outer rings of the air outlet of the check valve slot and tighten with screws. The other end extends directly into the outdoors through the reserved hole. If the exhaust pipe is connected to a public flue, it must be connected with a public flue smoke return check valve and sealed. If the smoke is exhausted outside the wall, it is recommended to install shutters outside the smoke exhaust pipe to avoid backflow. The diameter of smoke exhaust pipes is generally 15 cm and 18 cm, but now the popular ones in the market are 15 cm. It is convenient to leave the hole small and then expand it, and it is not difficult to change it to a smaller one if it is too big. However, if the sealing is not good, it will easily return the smell.

Note: if the smoke reaches the special flue, do not insert the smoke pipe too deep to increase the smoke exhaust resistance. If it leads to the outdoors, the exhaust pipe must extend 75px. The exhaust pipe extends outdoors or leads into a public cold air suction flue. The interface must be tight and exhaust gas is not allowed to be discharged into the hot flue. The shorter the range hood pipe, the better. If the pipe is stretched longer, after the range hood is turned off, a lot of oil smoke will accumulate in the pipe and cannot be discharged, and then pour back into the room.

Requirements for the installation of smoke exhaust pipes: the distance from the exhaust outlet to the machine body should not be too long, the turning radius should be as large as possible and there should be fewer turns, otherwise the smoke exhaust effect will be affected. The exhaust pipe extends outdoors or leads into a special cold air suction flue. The interface should be tight so that the exhaust gas does not need to be discharged into the hot flue. The air outlet pipe should not be too long, preferably no more than 2 meters, and bends should be minimized and multiple 90-degree bends should be avoided, otherwise it will affect the effect of smoking smoke.
