RIVA ADVANCE USER MANUAL 5
WARNING
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 EXPO-
SURE TO LESSER AMOUNTS OF CO MAY RESULT IN CARBON MONOXIDE POISON-
ING. EXPOSURE CAN BE FATAL AND EXPOSURE TO HIGH CONCENTRATIONS MAY
RESULT IN THE SUDDEN ONSET OF SYMPTOMS INCLUDING UNCONSCIOUSNESS.
Symptoms of CO poisoning include the following:
dizziness vision problems shortness of breath
headache loss of muscle control unclear thinking
nausea weakness unconsciousness
The symptoms of CO poisoning are often confused with those of inuenza, and the highest
incidence of poisoning occurs at the onset of cold weather or during 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 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 ADVANCE SV BOILER.

1. General Information
2. Technical Information (M210.32 CV)
The Riva Advance SV is a high efciency condensing, wall mounted gas boiler which provides
central heat. The boiler features a gas valve which modulates the energy input from 32,000
BTU/h to 125,000 BTU/h. The boiler is shipped fully assembled. All units are pressure and
combustion tested at the factory prior to shipping.
Key Features:
• Wall mountable - saving valuable oor
space.
• Several ue options available
• Electronic spark ignition
• Safety ow switch - positioned on the
main circuit, which monitors the ow and
protects the main heat exchanger from
thermal shock should there be a lack of
water in the system.
• Frost protection - contains an integral frost
protection system to prevent frost dam-
age which can occur in areas susceptible
to very cold weather conditions.
• Boiler operation recognition system -
should the boiler not be used for longer
than 24 hours, it then performs a con-
trolled system test to ensuring the motor-
ized components within the boiler do not
become inoperable due to lack of use.
• Gas valve modulation - the gas input
modulates based off central heating tem-
perature to within ± 2 ºF
• Diagnostic information system equipped
with three LED diagnostic lights for quick
error assessment.
