• Commonly occurring materials like: cleaning detergent, washing powder, serpentine, paraffin, gasoline, vapours of
gases, cleaning fluids, polishes, paints, cooking operation, etc. which may affect the reliability of this gas leakage detec-
tor. So, please keep the unit far away from the above materials.
LOCATING THE GAS ALARM
The MTG-3000H Gas Leakage Alarm is intended for indoor use in dry rooms where gas leakage might happen. It is im-
portant that the alarm signal can be easily heard in case of gas leakage. For detecting natural gas, the alarm should be
installed 15-30 cm below the ceiling and the maximum distance away from the furnace or gas appliances is 6 metres.
Make sure that the mains socket for connection of the 12V DC mains adapter is located max. 2m away from the instal-
lation position of the gas alarm. For detecting LPG, the alarm should be installed 15-30 cm above the floor and the max-
imum distance away from the furnace or gas appliances is 4 metres. The recommended areas are kitchen, garage or
recreational vehicle.
Areas to be avoided include the following:
• Situations where the temperature may fall below -10oC or rise above 40oC
• Do not locate Gas Leakage Alarm in turbulent air from fans, doors, windows, etc.
• Humid areas such as bathrooms, shower rooms where the relative humidity may exceed 95%
• Outside buildings, e.g. to guard open crates of bottled gas.
• Enclosed areas (e.g. in cupboards or behind curtains), which could prevent the alarm from responding in the event of
a gas leak.
• Areas in which dust or dirt can clog the sensor.
• Directly next to an oven, washbasin or drain.

Installation for LPG
• Electricity must be turned off at system supply before beginning installation to prevent electrical shock or equipment
damage.
• Having established the mounting location ensures that there in no electrical wiring orpipe work in the area adjacent to
the mounting surface.
• Take the mounting bracket and mark the two mounting holes locations.
• Drill holes in the positions marked.
• Insert wall plugs into the drilled holes.
• Screw mounting bracket to mounting surface. DO NOT OVER TIGHTEN.
• Plug in the connector of the 12V DC power source/ the transformer to alarm jack. When connected direct from a 12V
DC battery, a switch can be installed between the battery and the Gas Alarm.
• Connect the Gas Alarm to the mounting bracket by sliding on it.
• Connect the transformer to a 230V socket outlet. The Gas Alarm sounds within 5 seconds (self-test).
• When it stops, the green LED should light, and the Gas Alarm is ready for use.
• If you are uncertain which type of gas you use or you have problems installing the gas alarm you must have the alarm
installed by a suitably qualified person.
THE APPARATUS SHOULD BE INSTALLED BY A COMPETENT PERSON.
OPERATING THE GAS ALARM
Once the Gas Alarm has been installed a GREEN indicator light (LED) is on, and the Gas Alarm conducts a sound test it-
self, while the RED indicator light (LED) will be flashing quickly. After a few seconds, the Gas Alarm will be muted and
then reset into normally mode after this period. Then the Gas Alarm is ready for use. If gas is detected the unit will emit
a load pulsating alarm and a RED indicator light (LED) will flash until the gas concentration in the air decreased to a cer-
tain level. This will happen before any risk explosion.
If the power supply of 12V DC to the alarm has been disconnected, and then re-established, the alarm will conduct a
self-test again. This function ensures the Gas Alarm is in proper operation when in use.
TESTING THE GAS LEAKAGE ALARM
It is recommended that you test your gas alarm once a week to ensure the detector is working correctly.
Instruction on the use of any test method supplied with the apparatus and a warning on false conclusions that may be
drawn from the application of other methods, such as gas lighters, flammable vapours, etc.
Use gas from a cigarette lighter, and let it spread around the sensor which is situated at the grills in the left bottom side.
A loud pulsating alarm should sound and a RED flashing indicator light (LED) can be seen to indicate the correct func-
tion. The Gas Alarm will stop automatically when the air around the sensor is clean from gas. Test your Gas Alarm fre-
quently to insure proper operation.
CAUTION WHEN A GAS LEAKAGE OCCURS, THERE IS A POSSIBILITY OF SMELLING GAS PRIOR TO THE APPARATUS GIV-
ING AN ALARM.
WHEN ALARM OCCURRED
Keep calm, and carry out the following actions, not necessarily in the order given:
• Extinguish any naked flames, burning tobacco or candles etc. immediately.
• When the alarm signals are given under normal conditions, shut off the main gas tap, bottle valve, or leaking source
and open windows and doors for perfect ventilation.
• Do not switch any electrical devices (light switch, torch, door bell, telephone, intercom, or other electric consumers)
on or off.
• Touching electric switches is inhibited. Only a little spark could cause explosion.
• If leaking gas is indicated constantly or repeatedly, please contact your energy provider. Do not use the telephone or
any other electrical device near or around the gas leak to notify the provider.
If the alarm continues to operate, even after an alarm resetting action where appropriate, and the cause of the leak is
not apparent and/or cannot be corrected, vacate the premises and IMMEDIATELY NOTIFY the gas supplier and/or the gas
emergency 24h-service in order that the installation may be tested and made safe, and any necessary repair carried
out.
Description
If the alarm stops or a latching alarm is reset according to the instructions of the manufacturer and the reason for the
alarm having operated is identified, (for example a gas tap switched on with the burner unlit), after stopping the gas re-
lease and ensuring that all appliances are turned off, the main gas supply may be reinstated.
MAINTAINING YOUR GAS ALARM
Clean your gas leakage alarm regularly to prevent dust build up. This can be done using a vacuum cleaner with the
brush attachment. Clean gently around the front grilled section and sides.
If the alarm fails to operate currently, please send back to the address of manufacturer shown on the back labe l of the
detector.
REPLACEMENT PROCEDURE
With this gas alarm, after using for 5 years from the manufacturing date, the user should disconnect the electrical power

WHEN FAULT LAMP ON
The device carries out a self-checking routine for your safety. Possible errors are displayed by the FAULT LAMP flashing
and a coincident beeping noise from the device. This fault indicator may also be triggered by problem inside the device.
If a fault is indicated you must check first:
• Whether the ambient temperature is outside the specified range (-10°C to +40°C.
• Whether chemicals present in the air may have caused the fault, e.g. a high concentration of acid or alcohol. If this
cannot be confirmed, then try the device in another room. If no fault is indicated there then the problem lies in the sur-
roundings.
If the fault indicator is still active then the problem lies within the device itself:
• The gas alarm has suffered internal damage.
• The gas alarm has been used for approximately 5 years.
Then, it should be replaced.
