Gas detector installation instructions
First identify whether the gas to be detected is heavier or lighter than air.
»
Example of gas heavier than air: LPG. Gases lighter than air: natural gas.
Decide the installation height of the detector according to the weight of the
detected gas:
• If the gas is heavier than air, install the gas detector at 0.3 - 1.0 m height
from the floor, and up to 1.5 m away from the gas source.
• If the gas is lighter than air, install the gas detector at 0.3 - 1.0 m down
from the ceiling, and up to 1.5 m away from the gas source.
Power the gas detector to a 230V source. A short beep will be heard
»
immediately.
For the next 180 seconds (sensor priming period), the 3 LEDs (red, yellow
»
and green) will light alternately.
After this priming time, the green LED will remain lit. The detector is now
»
in normal operating condition.
In the event of an alarm, the red LED will often flash accompanied by a
»
continuous sound. If the detector is connected to a solenoid valve, it will
send an electrical pulse to it. The solenoid valve will shut off the gas flow. To
interrupt the alarm, unplug the detector or wait until the concentration of
the gas that triggered the alarm decreases (see Safety warnings, page 9).
In case of error, the yellow LED will remain constantly lit. Remove and
»
reinsert the detector into the outlet. If the error persists, call a specialist
service center.
Instructions for installing and connecting the solenoid valve
• The solenoid valve must only be installed by qualified personnel.
• The solenoid valve must be installed after the main internal gas valve.
• The solenoid valve must be installed in the direction of the gas flow, marked
on the solenoid valve. The coil must not be mounted face down. The
solenoid valve can be installed horizontally or vertically.
• The solenoid control wires must be connected correctly. The white thread
is positive and the black thread is negative. An incorrect connection can
lead to a short circuit.
• Reverse polarity and incorrect voltage can damage the solenoid valve.
