Is there a direction for using a flame arrester on a stove?

Flame arresters have a direction; they come equipped with arrows on their bodies to indicate the flow direction!

Flame arresters are divided into vent flame arresters and pipeline flame arresters, both of which have a directionality. 1) Vent flame arresters: Installed on the vent pipes of storage tanks (or tank cars), they serve to prevent external flames from entering the tanks (or tank cars). They are available in end-mounted types and standard types. End-type: One end is open to the atmosphere; to prevent dust and rainwater from entering the flame arrester, a weatherproof cap that opens under temperature control is installed on the top. The pipe-end type vent flame arrester is of explosion suppression type. Standard type: Connected to pipes at both ends, and in communication with the atmosphere through the downstream pipe. They are divided into flame arrestant types and detonation arrestant types. (2) Pipe flame arrester: Installed in a closed pipeline system to prevent flames at one end of the system from spreading to the other end. They are divided into flame arrestant types and detonation arrestant types.

1 The flame arrester should be installed near the ignition source and have a directional orientation. 2 The vent flame arrester should be installed as close as possible to the end of the pipeline, while also taking into account ease of maintenance. Generally, a pipe-end type vent flame arrester is used ； If a standard vent flame arrester is chosen, it is necessary to take into account the influence of the piping length and shape of the pipe connected downstream from the arrester on the selection of its performance type (either for preventing combustion or for preventing detonation), and to determine the specifications of the standard vent flame arrester based on the conditions of the medium and the installation environment. 3 When installing pipe blast and deflagration arrestors, it is important to ensure that their \"detonation wave absorbers\" are facing the direction where detonations may occur; otherwise, they will lose their ability to prevent detonations. 4 The connection between the flame arrester and the pipeline is generally by flange, while smaller-diameter pipelines use threaded connections

The direction for using a flame arrester on a stove is specified, with arrows usually indicated on it.

Flame arrestors have a direction; they should be installed as indicated by the arrows
