Any appliance that burns natural gas, propane gas, fuel oil, wood or coal is capable of pro-
ducing carbon monoxide (CO). Carbon Monoxide (CO) is a gas which is odorless, colorless
and tasteless but is very toxic. CO is lighter than air and thus may travel throughout the
building.
BRIEF EXPOSURE TO HIGH CONCENTRATIONS OF CO, OR
PROLONGED EXPOSURE TO LESSER AMOUNTS OF CO MAY
RESULT IN CARBON MONOXIDE POISONING. EXPOSURE CAN BE
FATAL AND EXPOSURE TO HIGH CONCENTRATIONS MAY RESULT
IN THE SUDDEN ONSET OF SYMPTOMS INCLUDING
Symptoms of CO poisoning include the following:
The symptoms of CO poisoning are often confused with those of infl uenza, and the highest
incidence of poisoning occurs at the onset of cold weather or during fl u season.
A victim may not experience any symptoms, only one symptom, or a few symptoms.
Suspect the presence of carbon monoxide if symptoms tend to disappear when you
leave your home.
The following signs may indicate the presence of carbon monoxide:
• Hot gasses from appliance, venting system pipes or chimney, escaping into the living
space.
• Flames coming out around the appliance.
• Yellow colored fl ames in the appliance.
• Stale or smelly air.
• The presence of soot or carbon in or around the appliance.
• Very high unexplained humidity inside the building.
If any of the symptoms of CO occur, or if any of the signs of carbon monoxide are
present, VACATE THE PREMISES IMMEDIATELY AND CONTACT A QUALIFIED
HEATING SERVICE COMPANY OR THE GAS COMPANY OR THE FIRE
DEPARTMENT.
ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM
WORK ON YOUR BIASI RIVA COMBI BOILER.
