Installation matters
1. Select an appropriate location for the detection of natural gas and install it on the low dry ceiling at 0 --1,0 meters, close to the gas source, but away from the gas source radius I.5 meters;
2. Fix the mounting plate in the selected position with mounting screws, insert the detector and check whether it is firm;
3, the family should also pay attention to the installation, not being too close to gas appliance installation position, so as not to probe been baking stove flame, cannot install where big lampblack, lest cause false alarms or lead to probe into the pores of the air intake, thus affect the sensitivity of the detector, also cannot be installed on the exhaust fan, doors and Windows with strong and bathroom water vapor.
