To detect gases lighter than air (such as methane and ammonia), a fixed gas detector should be installed at a higher position, and a conical collector should be used.

To detect gases heavier than air (such as butane and sulfur dioxide), the detector should be installed at a lower position.

Consider the possible behavior of escaping gas under the action of natural and pressurized airflow. Install the detector in the ventilation duct when appropriate.
