Installation method of the exhaust pipe of the range hood:

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. 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.

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. The 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.
