Installation method of the exhaust pipe of the range hood:

1. Insert one end of the exhaust pipe 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.

2. If the smoke is discharged to the flue for * * *, don't 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 3cm.

3. The smoke exhaust pipe 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.

Extended information:

The range hood, also known as the range hood, is a kitchen appliance for purifying the kitchen environment. It is installed above the kitchen stove, which can quickly pump away the waste burned by the stove and the oil fume harmful to human body generated in the cooking process, and discharge it outdoors, thus reducing pollution, purifying the air, and having the functions of anti-virus and anti-explosion.

In the early days, the smoke exhaust in family kitchens was done by exhaust fans. Although the exhaust fan can remove most of the oil fume in the kitchen, it is unable to solve the pollution of the oil fume produced in cooking to the whole kitchen. The oil fume produced in cooking contains many substances harmful to human body. If people work in a room full of oil fume for a long time, it will lead to many diseases.
