Installation
Choose the correct place to install the device. The detector must be placed inside the room where gas
consuming devices have been installed i.e gas cooker, water heaters, gas burners. The detector must be
placed form 1m up to 4m away of these devices. Choose a wall position not far than 30cm of the floor. The
detector must be installed in a position which is away from openings, doors etc.
Avoid positions in the direct air flow of an air-condition. Do not place the detector above kitchen sinks, near
pit ventilators, near pits itself near ventilation fans. Avoid also places with high alcohol, ammonia, cleaning
and shining liquid, solvent concentration. Avoid places with intense use of spray. Exposing the detector to
such contaminants for a short or long period can seriously defect the sensitivity. Do not place the detector
in any outdoor position. Do not install the device in places where humidity or temperature exceeds the
operating limits as shown in the characteristics table.
Unscrew the safety screw in the bottom of the device and remove the front cover. Place the remaining to
the position you have already chosen, mark the correct hole positions in the wall and screw the two screws
carefully.
The detector can drive safety valves of the following types:
Safety Valve N.O. ~230VAC
Safety Valve N.O. 12VDC
Safety Valve N.C. ~230VAC
Safety Valve N.C. 12VDC
For each different safety valve type or power source a different wiring connection is needed.
