Biasi Riva Combi Installation & Operation Instructions page 7

Any appliance that burns natural gas, propane gas, fuel oil, wood or coal is capable of
producing 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:
dizziness
headache
nausea
The symptoms of CO poisoning are often confused with those of influenza, and the
highest incidence of poisoning occurs at the onset of cold weather or during flu 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 flames in the appliance.
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.
