1. Before tiling the kitchen, check for voids or cracks around the kitchen flue opening yourself. Kitchen walls, including the flue, should be screened before tiling to ensure that the wall tiles adhere to the wall. The walls of the flue are usually thin, so when using screws or expanding plugs to fix the metal mesh, it is important to avoid breaking the flue, otherwise, after tiling, the smoke will come out of the flue and run down the gaps.

2. In the range hood and flue between the appropriate location to add a good sealing function of the wind tunnel gates, gates in the role of the power to automatically open, automatically closed when not in use, can isolate the flue in the odor into the kitchen.

3. Purchase a hood that prevents the return of air to ensure that smoke is discharged from the flue in one direction, rather than from the flue back into the room. After the exhaust pipe is installed, use glue to seal the gap between the exhaust pipe and the flue to prevent future smoke.
