The installation of flue check valve to note:
Be sure to keep 1, deputy flue
Each kitchen has the flue, flue is divided into main at the same time, throughout the building, the main flue and flue is relatively independent. General lampblack is first to the deputy flue in the home, and then through the diaphragm plates into the main flue, which can ensure household lampblack is isolated. And if the vice flue connected directly to the main flue, will be due to low pressure DaoYan or smoke.
2, the construction should pay attention to details
First, select the smoke lampblack machine installation location is important. Pipes as short as possible. Some owners have to beautiful, pull the pipe is longer, as a result, after turn off lampblack machine, pipe will gather many lampblack not to go out, then fell back to the room. In addition, in order not to damage the original main flue, and the opening direction can not optional change, be sure to play inside the vice flue.

First before the window or wall to open hole must be with the approval of the property; Secondly, pay attention to safety problems, generally is the metal material at the end of the exhaust pipe, if the open hole is too small, metal heat transfer may make glass crack, and pedestrians, and pipe lead to out of the window, the strong north wind to blow will cause lampblack flow backward. Best will go down the pipe after pipe out, this can also avoid the rain rain water into the pipe, and the windshield on the outside.
4, non-return valve frequently replaced
If have deputy flue to dismantle, or need to prevent DaoYan effect is better, then use the flue check valve.

However, after install the check valve to regular cleaning, otherwise it will make the check valve is open, lose their effect, and the best flue check valve replaced every two years or so.
