DANGER

Make sure that the following are observed when a gas 

alarm sounds. There may be a risk of explosion.

Leave the building immediately, opening doors and windows as you leave.  

Take others with you.  If you are outside when you smell the gas, leave the 

area immediately.

 

Avoid causing a spark, which might cause the gas to explode:

1.  Do not remove the connector from the lithium battery

2.  Do not light a match or smoke.

3.  Do not turn appliances or lights on or off.

TEL: (847)749-3064

Find a phone away from the area and immediately call 911 and/or your 

natural gas utility.  You can report leaks anonymously.  Always call to 

report the problem.  Do not assume someone else will do it.

 

Do not re-enter the area until the source of the leak is found and corrected.  

Follow directions from utility employees or emergency responders who are 

on site.

How to Install

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.  

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 6 to 12 inches (0.15 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. 

 Wall Mounting

Tools you will need:Drill with 3/16” or 5mm drill bit,Phillips head 

screwdriver, hammer.

1. Choose a location on the wall between 6 inches (0.15 meters) to 12 

inches (0.3 meters) from the ceiling.  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 fl ush 

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. 

Drill a hole

Insert the plastic screw anchor

Fix the screw temporarily

5.  Hang the Mounting Tab on the screw.

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.

Where This Alarm Should Not Be Installed

 In a small enclosed space.

 Directly above or near sources of water or humidity such as a sink, 

cooktop, dishwasher or bathroom.

 Although it is important to install detectors in rooms were gas 

appliances exist, it is recommended the detector 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 

detectors at a reasonable distance from a gas source, and thus reduce 

“unwanted” alarms. Unwanted alarms can occur if a detector is placed 

directly next to a gas source. 

 If you must install the detector near a cooking appliance or cooktop 

hood, install at least 5 feet (1.5 meters) from appliance because cooking 

vapors or grease may contaminate the detector. 

 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 that is dusty or dirty.

 In an area where organic solvents exist.

 In a damp or very humid location.

Disposal

When disposing of this product, do so in accordance with local laws and 

regulations.

Also, remove the lithium battery when disposing.

WARNING

portion does not short.

  Such a short may cause heat generation, an explosion, or ignition to 

occur.

 

Any of these may result in injury or fi re.
