Natural gas leaks can source from any faulty gas appliance such as an oven, cook top, dryer, furnace, etc. They might also come from old or damaged pipes inside the home. It is important to install a natural gas alarm in each of these areas where a gas appliance is located. Learn more here

The lower explosive limit (or LEL) refers to the lowest concentration (by percentage) of a gas that is capable of producing a flash of fire in the presence of an ignition source. For methane, the LEL is 5% volume in air, which corresponds to 100% LEL. The natural gas alarm is designed to sound off when detecting methane concentrations as low as 10% LEL, or 0.5% volume in air.

There should be a gas alarm installed in every room that has a gas appliance (i.e. gas water heater, gas dryer, gas oven, etc.) Early detection of natural gas leaks is important to saving lives and preventing property damage. Learn more here

A natural gas alarm should be installed indoors in any room that has a gas-fueled appliance. This can include a stove, furnace, water heater, gas fireplace, or a gas dryer. It should be installed on the wall, within 12 inches from the ceiling. Although it is important to install natural gas alarms in rooms where gas appliances exist, it is recommended that a natural gas alarm be placed as far away from these appliances as possible, preferably more than 10 feet (3 meters) away. This should help reduce "unwanted" nuisance alarms, which can occur if a natural gas alarm is placed directly next to a gas source. Learn more here

A natural gas alarm should not be installed in the peak of a cathedral ceiling. Natural gas detectors should not be installed directly above or near sources of water or humidity such as a sink, cooktop, dishwasher or shower. Natural gas alarms should not be installed in a damp or very humid location, such as a bathroom. They should not be installed next to a door or window, a ventilation fan, a room return, or an HVAC duct. They should not be installed in an area where the temperature will drop below 32°F (0°C) or exceed 122°F (50°C). The natural gas alarm should not be installed in an area that is dusty or dirty, or where organic solvents and silicone vapors exist. The natural gas detector should not be installed outside.
