Customer Reviews For The New Cosmos Natural Gas Detector - ML-310

Gas detectors should be installed in all rooms where a gas leak may occur or a gas appliance is located. Examples are a kitchen (gas leaks from gas ovens and cook tops), laundry (gas leaks from a gas clothes dryer), and furnace area (gas leaks from furnace burners or boilers). However, do not install closer than 10 feet (3 meters) from gas appliance to avoid false readings. It is possible that gas leaks may migrate along pipes so consideration should be given to place gas detectors in multiple rooms. Gas detectors should be located between 4 to 12 inches (0.1 to 0.3 meters) from the ceiling. Air movement around the detector must not be impeded by items hanging from the ceiling or near the ceiling such as curtains, drapes, ceiling fans. The detector should not be installed in the peak of a cathedral ceiling.

1. Open the battery cover on the back of the detector.
2. This cover slides out of place. To open, place both thumbs on the back of the battery cover where the battery cover hooks snap into place.
3. Push down where the battery cover snaps into place with your thumbs and slide the cover out. Some force is required.
4. Connect the included lithium battery by inserting the battery harness connector into the product.
5. Do NOT remove the plastic wrap surrounding the battery pack.
6. The battery connector has a large notch on it that faces up when installed correctly. There is only one way in which the connector can be installed. A small portion of the connector will be exposed when connected properly. You should hear it click into place.
7. After connecting the battery, place the battery with the labels facing down and the battery wires wrapping around the top side of the battery pack. For the best fit, it is recommended to have the negative (-) terminals face toward the outer edge of the detector.

If at any time your natural gas detector's alarm sounds or if you ever smell or hear a natural gas leak:

• Evacuate immediately and take others with you.
• Do not use a phone; light a match; turn on or off lights, flashlights, or appliances; start a car; or do anything else that could create a spark or flame and cause the gas to ignite or explode.
• Call 911 once you are safely outside the premises. You can report leaks anonymously.
• Do not re-enter the premises until told to do so by authorities.

In the event of a gas leak, you may smell natural gas before the natural gas detector's alarm is activated. Whether or not the unit's alarm is sounding, if you smell gas, act fast. Report the leak once you are safely outside.

Once you have determined the proper location for your detector, follow these steps to activate the device:

1. Open the see through battery door on the back of the gas detector by pushing down and away from the left side of the door. The door should slide out and to the right, away from the device.
2. Connect the included lithium battery pack by inserting the battery harness connector into the back of the device. Once the lithium battery is connected, the gas detector's green LED (power) will flash for 1 second.
3. After connecting the battery, insert the pack and connector harness inside the battery compartment and slide back on the battery door.
4. After the battery is plugged in, the detector will enter an initialization period for approximately 30 seconds. A "Beep" will sound after this 30 second period and the detector will begin monitoring.
5. After the 30 second initialization period, press and hold the Test Switch for more than 3 seconds to test the alarm.
6. Congratulations! Your device is ready to detect natural gas and can now be safely mounted.

• Smell - A distinctive, strong odor similar to rotten eggs
• See - A white cloud, mist, fog, bubbles in standing water, blowing dust, or vegetation that appears to be dead or dying for no reason
• Hear - Roaring, hissing, or whistling

The ML-310 detector is easily wall mounted with only one screw, no bracket necessary. Tools you will need: Drill with 3/16" or 5mm drill bit, Phillips head screwdriver & hammer.

1. Choose a location on the wall between 4 inches (0.1 meters) to 12 inches (0.3 meters) from the ceiling. Align the detector against the wall and make a mark in the mounting tab of the detector where you will drill the mounting hole.
2. Use a 3/16" (5 mm) drill bit to drill the mounting hole.
3. Insert the plastic screw anchor into the mounting hole until it is flush with the wall. If necessary, tap it gently with a hammer.
4. Tighten the screw into the anchor until the screwhead is about 3/16 inch (5 mm) away from the wall, leaving enough space for the Mounting Tab.
5. Hang the Mounting Tab on the screw.
6. Lightly tighten the screw to secure the detector.
7. Press and hold the Test Switch for more than 3 seconds to test the alarm.

The natural gas detector was designed to be as low maintenance as possible. If the unit begins to sound its low battery signal - a single intermittent chirp - contact New Cosmos Electric Co. at 1-847-749-3064 to obtain a replacement battery; these batteries are not available in stores.

The manufacturer recommends testing the unit at least once a week and cleaning the unit once a month by gently vacuuming the outside of the unit; do not use water, cleaning, and maintenance.

The natural gas detector is a safety device that monitors the air in the area where the unit is installed in your home. If the unit detects a potential natural gas leak in that area, it will beep loudly (similar to a smoke detector) and provide the following audible alarm: "Danger. Gas-leak explosion risk. Evacuate, then call 911."

Yes. Since the unit is powered by an internal battery, the natural gas detector should continue to function during a power outage.

No, the natural gas detector will only detect the presence of natural gas in the area where the unit is installed. It will not detect fire, heat, smoke or the presence of any other gases, including carbon monoxide (CO).

No, the natural gas detector will only monitor the air in the area where the unit is installed. Natural gas leaks could be present in other areas and/or on other floors of your home or building without reaching the natural gas detector. As such, the unit's alarm may not sound in the event of a natural gas leak in a remote part of your home or building. Doors or the obstructions may also affect the rate at which natural gas reaches the natural gas detector. You should install separate gas detectors as needed in other areas of your home where natural gas appliances are used.

No, the natural gas detector's alarm may not be heard in all rooms or situations. Since the natural gas detector is installed in a limited area of your home or building - such as the kitchen, for example - people sleeping or awake in other rooms or on other floors may not hear the unit's alarm in the event of a natural gas leak. People may not hear the alarm if the sound is at a distance and/or blocked by closed doors and/or other obstructions. Noise from traffic, stereos, radios, televisions, air conditioners, appliances, or other sources may also prevent people from hearing the unit. The unit's alarm is not intended for people who are hearing impaired.
