This
product is an indoor combustion gas detector with high
stability , hereinafter called detector, used for combustion gas
leak detection. It uses highly stable semiconductor gas sensor
with features of stable performance and low drift of
sensitivity. When it senses combustion gas leak that reaches
the set alarm level, it will give out alarm sound with red LED
flashing. The detector is applied in indoor places where
combustion gas leaks possibly happen.

First
identify
your
gas
heavier
or
lighter
than air
.
Heavier
gases: LPG etc. Lighter gases: natural gas, marsh
gas, artificial coal gas etc.
2.
Choose a suitable installing position according to gas
specific gravity. Detecting heavier gases, installation
height 0.3-1.0m from floor , semi-diameter to gas source
<1.5m; Detecting lighter gases, installation height 0.3-
1.0m from ceiling, semi-diameter to gas source < 1.5m
(refer to the following image).

3. Fix the attached base into a wall firmly with screws
and hang the detector.
4. Do not make it close to gas stoves when installing at home
in case it is roasted by flame. Neither places with heavy oil
or smoke that may cause false alarms or block the gas
convection holes and influence the detector sensitivity.
Also it is can not be installed near to exhaust fans,
windows, doors, and places with great vapor in bathrooms.
5. Connect the wires correctly according to the wire harness
