INSTRUCTIONS FOR USE
Choosing the mounting place
It depends from the relative weight of the detected gas. For LPG detection
must be mounted within 30cm from the ceiling.
CAUTION:
This gas detector indicates the presence of gas to the sensor, but gas can be found
in other areas where it can not be detected. This gas detector is used to detect gas
regardless of the source of the issue. It is not suitable to detect smoke, fire or other
gases. Gas detectors intended for use only in closed spaces. Do not use outdoors.

GAS DETECTOR FOR LPG
Avoid to install gas detector in the position in which its normal operation could
be compromised:
- directly over the cooking stoves;
- in an area where the temperature may drop below -10°C or exceed + 40°C;
- directly above a sink;
- in an enclosed space (e.g. in a cupboard or behind a curtain);
- next to a door or window;
- next to an extractor fan;
- where dirt and dust may block the sensor;
- in a damp or humid location.
Do not use the following substances near to the device:
- solvents and diluents;
- alcohol, fuels;
- silicones products and colors;
- perfumes;
- cleaning detergents;
- spray products.
INSTALLATION:
Install the unit in a controlled area on a carrier or directly on the wall.
To install the gas detector:
- Use the mounting holes and through 2 mounting screws and dowels secure unit.
- Open the plastic housing of the appliance by pressing the pin in the bottom of the
vessel and the subsequent lifting of the lid.

Choosing the type of electromagnetic valve
CD34 can command either normally open or normally closed valve. You can
change the working mode with moving the jumper switch.
-To set Normally closed valve place the jumper to NC-C
-To set Normally open valve place jumper to C-NO
WARNING:
-Installation and wiring of gas detector must be made by qualified technician
with compliance with the current standards.
-Before wiring this gas detector turn mains power off.
-To ensure correct operation periodic functional check is advisable. In order to
check the proper efficiency of the device sensor a specific test gas bottle must
be used (code Tecnogas 553445). Any other method for testing, such as the use
of cigarette lighters or flammable substances can lead to wrong conclusions
and damage the sensor.
WARNING in case of alarm:
-Extinguish all fire sources.
-Stop gas supply by closing main gas valve.
-Do not turn on or off any electrical devices.
-Open doors and windows to increase ventilation.
When alarm stops it is necessary to find gas leaking cause. If alarm persists and
CD34 the leak can not be found, vacate the premise and immediately inform the gas
emergency service.
