• Good ventilation is recommended when household cleaning supplies or similar contaminants
are used.
• Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient
conditions, such as:

Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/
humid air with extended periods between cycles).

Negative pressure differential resulting from the use of exhaust fans.

Simultaneous operation of several fuel-burning appliances competing for limited internal air.

Vent pipe connections vibrating loose from clothes dryers, furnaces or water heaters.

Obstructions in or unconventional vent pipe designs which can amplify the above situations.
HOW TO INSTALL THIS CO AND GAS ALARM
IMPORTANT: Read all instructions before using this product.
1. Determine the best location for your CO and Gas Alarm.
2. Your alarm is equipped to be mounted as a direct plug-in unit. The unit can be plugged directly
into a wall outlet.
3. Activate the 9 Volt battery. Remove and discard the pull tab. Make sure the battery door is closed
and latched.
4. The green power LED should be on continuously. It may take up to 3 minutes for the alarm to
begin monitoring for CO and gas.
5. Test the alarm following installation and weekly thereafter.
NOTE: For your convenience, we provide separate labels for the French-language product markings.
If you choose to utilize those markings, remove the label from the backing and apply it to the alarm.
Carefully align the label in the appropriate space and press firmly to ensure the label permanently
adheres to the alarm.
WHAT YOU SHOULD DO IF THE ALARM SOUNDS
Never disconnect your CO and Gas Alarm to silence an alarm. The alarm will automatically sense
when the level of CO and natural gas in the air falls below the danger level. You should stay outside
the residence in fresh air until the alarm is silenced. When the alarm sounds, do not stand too close
to the alarm. The sound produced by the alarm is loud because it is designed to awaken a person in
an emergency. Prolonged exposure to the alarm at a close distance may be harmful to your hearing.
Two self-adhesive labels have been provided with instructions indicating what to do if the alarm
sounds. Add the phone numbers of your emergency services provider and a qualified technician to
each label. Place one of the labels in a visible area next to the alarm and place the other label near
a source of fresh air which will be used as a gathering place if the alarm sounds.

READ CAREFULLY.
THIS UNIT IS SEALED. THE ALARM COVER IS NOT REMOVABLE !
Leave your CO and Gas Alarm plugged in year-round. CO and gas problems can occur any
time during the year and this alarm can only alert you if it is plugged in and receiving power.
This Alarm i s intended for use in a standard, unswitched 120VAC wall outlet. It is not intended for
use in extension cords, power strips or outlets controlled by a switch or dimmer. These may not
provide continuous power to the unit. When fully powered, it samples the air continuously. A microchip
inside the unit stores each reading and remembers the levels it has been exposed to over time. The
unit goes into alarm mode when it has been exposed to a "critical" level.
• Test the alarm once a week. If the alarm ever fails to test correctly, have it replaced immediately.
If the alarm is not working properly, it cannot alert you to a problem.
• This combination CO and Natural Gas Alarm is intended for residential use and is not suitable for
use in hazardous locations as defined in the National Electrical Code.
• This unit must be powered by a 24 hour circuit. Be sure the circuit cannot be turned off by a
switch, dimmer or ground fault circuit interrupter (GFCI). Failure to connect this unit to a 24 hour
circuit may prevent it from providing constant protection.
• This alarm must have AC or battery power to operate. If AC power fails and the battery is dead or
missing, the alarm cannot operate.
• The alarm will check for the presence of gas at the sensor less frequently when powered by the
backup battery. Gas could be present during the period between checks without going into alarm,
especially during a condition that results in a rapid buildup of gas.
• This product is intended for use in ordinary indoor locations or family living units. It is not designed
to measure CO levels in compliance with Occupational Safety and Health Administration (OSHA)
commercial or industrial standards. Individuals with medical conditions which may make them
more sensitive to carbon monoxide may consider using warning devices which provide audible
and visual signals for carbon monoxide concentrations under 30 ppm. For additional information
on carbon monoxide and your medical condition, contact your physician.
