A CO Alarm is an excellent means of protection. It monitors the air and
sounds a loud alarm before Carbon Monoxide levels become threatening
for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home appliances.

Clean chimneys and flues yearly. Keep them free of debris, leaves, and

nests for proper air flow. Also, have a professional check for rust and

corr
air movement and cause backdrafting. Never “cap” or cover a chimney
in any way that would block air flow.
Test and maintain all fuel-burning equipment annually. Many local gas

or oil companies and HVAC companies offer appliance inspections for
a nominal fee.
Make regular visual inspections of all fuel-burning appliances. Check

appliances for excessive rust and scaling. Also check the flame on the

available on all fuel-burning appliances. Make sure appliances are
vented to the outside. Do not grill or barbecue indoors, or in garages

Check the house or garage on the other side of shared wall.

PREPARE YOUR ALARM LABELS
Find the pair of self-adhesive labels included with this Smoke/CO Alarm.
• On each label write in the phone number of your emergency responder
(like 911) and a qualified appliance technician.
• Place one label near the Smoke/CO Alarm, and the other label in the

NOTE: A qualified appliance technician is defined as “a person, firm,
corporation, or company that either in person or through a representative, is
engaged in and responsible for the installation, testing, servicing, or replacement of heating, ventilation, air conditioning (HVAC) equipment, combustion
appliances and equipment, and/or gas fireplaces or other decorative combustion equipment.”
