Page 12: Installation
Installation Installation The device should be installed where gas leaks are expected. The installation position depends on the gas density, either in the upper area of the room under the ceiling for gases lighter than air or close to the ground for gases heavier than air. Also consider how air movement may affect the ability of the device to detect gas. - Page 13 Installation Wall or Pipe Mounting For pipe mounting a pipe mounting kit is necessary (→ chapter 8.6 "Pipe Mounting Kit"). Install the Backplate Use the two keyhole slots for attaching the mounting plate to the wall. Use 6mm diameter screws and suitable plugs.
