General description & intended use

DANGER
If you smell natural gas, evacuate the area right away, then call 911 or your gas utility. Do not wait for the alarm to sound.

DANGER
This Gas Alarm is designed to act as a continuous monitor of natural gas that reaches the sensor. This detector should not be used as a short-term testing device to perform a one-time check for the presence of natural gas, as starting the device in the presence of natural gas may cause an explosion.

This Gas Alarm detects natural gas. Natural gas is a fossil fuel that is primarily made up of methane. It is commonly used for cooking, home heating, and water heating. Natural as is typically supplied through the main utility line connected to your home. It is a highly flammable chemical compound. Although it happens rarely, a natural gas leak can sometimes occur inside the home. This can be dangerous because it increases the risk of explosion and fire.
This product is intended to detect natural gas that is not detected by smell. Natural gas is typically odorless and colorless unless your supplier treats it with a chemical to make it smell. Individuals with a diminished sense of smell may not be able to detect even treated natural gas. If you are not sure which gas your home uses, contact your utility company.
When this product detects natural gas at a concentration of greater than or equal to 10% LEL for methane, it is designed to beep 4 times and state “Danger – gas leak explosion  risk – evacuate, then call 911” followed by an additional 4 beeps and state “Peligro – riesgo de explosión for Fuga de gas – evacuar, luego llama al 911.”
It is possible that you may smell natural gas before the alarm is activated.
If you do smell natural gas, do not wait for the alarm to sound. Evacuate right away, then call 911.
This Gas Alarm is designed to act as a continuous monitor of natural gas that reaches the sensor. This Gas Alarm should not be used as a short-term testing device to perform a one-time check for the presence of natural gas, as starting the device in the presence of natural gas may cause an explosion.

Gas Alarm parts

Installing the Gas Alarm

Selecting Gas Alarm location
WARNING

• Installation in an improper location can affect the sensitive electronic components in this device.
• Improper placement can prevent the detection of natural gas.
• Improper placement can prevent you from hearing the alarm. Install in a location where you can hear the alarm sound loudly from all sleeping areas.
• Place out of reach of children. Under no circumstances should children be allowed to handle this device.
  Gas Alarms 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 cooktops),  laundry (gas leaks from a gas clothes dryer), and furnace area (gas leaks from furnace burners or boilers). It is possible that gas leaks may migrate along pipes so consideration should be given to placing Gas Alarms in multiple rooms. Consider placing a Gas Alarm in each bedroom where the occupant closes the door while sleeping.
  Although it is important to install Gas Alarms in rooms where gas appliances exist, it is recommended the Gas Alarm be placed as far from these appliances as possible,  preferably more than 10 feet (3 meters) away. The placement recommendations are intended to keep these Gas Alarms at a reasonable distance from a gas source, and thus reduce “unwanted” alarms, which can occur if a Gas Alarm is placed directly next to a gas source.
  Avoid placing the Gas Alarm near a cooking appliance or cooktop hood. If you must do so, install at least 5 feet (1.5 meters) from the cooking appliance or cooktop hood because cooking vapors or grease may contaminate the Gas Alarm.

The product should be insta

• Between 4 to 12 inches (0.1 to 0.3 meters) from the ceiling.
• In an area where it will not be impeded by items hanging from or near the ceiling such as curtains, drapes, ceiling fans.
• At least 5 feet (1.5 meters) from the cooking appliance or cooktop hood.
• At least 10 feet (3 meters) from gas appliances.

The product should NOT be installed:

• In the peak of a cathedral ceiling.
• Directly above or near sources of water or humidity such as a sink, cooktop, dishwasher, or shower.
• Next to a door or window.
• Next to a ventilation fan.
• Near a room return or HVAC duct.
• In an area where the temperature will drop below 32°F (0°C) or exceed 122°F (50°C).
•  In an area where organic solvents or silicone vapors exist.
• In a damp or very humid location, such as a bathroom.
