Wall Mounted Combustible C6H6 HCN Carbon Dioxide Alarm
Fix the appliance on the wall at a horizontal distance as 2~4m from the cooker or gas source;
●LPG:Fix it within 0.3 meters above the ground;
●Natural Gas:Fix it within 0.3 meters below the Roof
Such location should be avoided:
◆Near the windows or passage with strong wind,
◆Water fog and drop or such moist place;
◆Easy polluted or high tem environment near Oven,
