Dear Customer:
Thank you for buying a Biasi Riva Advance SV.
The Riva Advance SV is a high efficiency condensing, wall mounted gas boiler which provides
central heat supply water.
We realize that it is not possible to answer all questions about the Riva Advance SV system in
this manual. Reading this installation manual does not make the reader an expert in all aspects
of installation and operation, and does not replace the need for a qualified, licensed heating
contractor. We urge you to contact your installing contractor or distributor if you are in question
about any aspect of your boiler’s performance. Our main concern is that you are satisfied with
your boiler and its performance. We require that your contractor complete efficiency tests using
instruments.
The external controls and accessories listed in this manual (excluding those supplied inside
the boiler) are intended to serve as guidelines rather than specific recommendations. We realize that other makes and models of such devices are available and can be used as successfully as those we specify. The installing contractor is the best judge of a system’s specific
requirements, as well as the local availability of certain makes and models of controls and
accessories. The preceding does not apply, however, to the equipment that comes with every
boiler, such as the overheat control and pressure relief valves. The installation of the specific devices supplied with every boiler is absolutely necessary to the safe operation of
the boiler and protection of the heating system.
All BIASI wall hung boilers are built in accordance with the ASME boiler and pressure vessel
code, and bear the “H” stamp. The Entire range of applications for the Riva Advance SV has
been tested to standard CSA 4.9 and is CSA compliant.
This Riva Advance SV has a 2 year warranty, a copy of which is provided with the boiler.
Please be sure to return the warranty registration card as the warranty will be void without your
boiler’s serial numbers (located on the ratings label affixed to the boiler), date of installation
and the name of your installer being on record in our files.
Thank you for purchasing our Riva Advance SV. If you have questions or comments, please
don’t hesitate to contact us immediately. Our goal is 100% customer satisfaction.

WARNING
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
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 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.
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.

1. General Information
The Riva Advance SV is a high efficiency condensing, wall mounted gas boiler which provides
central heat. The boiler features a gas valve which modulates the energy input from 41.000
BTU/h to 116.000 BTU/h. The boiler is shipped fully assembled with the components listed on
page 10. All units are pressure and combustion tested at the factory prior to shipping.
Key Features:
• Wall mountable - saving valuable floor
space.
• Several flue options available
• Electronic spark ignition
• Safety flow switch - positioned on the
main circuit, which monitors the flow 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 damage 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 controlled system test to ensuring the motorized components within the boiler do not
become inoperable due to lack of use.
• Gas valve modulation - the gas input
modulates based off central heating temperature to within ± 2 ºF.
• Diagnostic information system equipped
with three LED diagnostic lights for quick
error assessment.

9. Venting
The Riva Advance SV is a mechanical draft, side wall vented boiler. There are two side wall
flue options available – separate and coaxial. The coaxial option has one configuration shown
on the next page. The separate option has two possible configurations shown on the following pages. There is also a vertical roof venting option. Regardless of what vent kit is installed,
they should all conform to the Provisions for combustion and ventilation air in accordance
with section 5.3, Air for Combustion and Ventilation, of the National Fuel Gas Code,
ANSI Z223.1, or Sections 7.2, 7.3 or 7.4 of CAN/CGA B149, Installation Codes, or applicable provisions of the local building codes.
If the Biasi Riva Advance SV replaces a boiler that was attached to a common vent system, the
common venting system is likely to be too large for proper venting of the appliances remaining
connected to it. To ensure the remaining appliances will function properly, the test procedure
below should be followed:
At the time of removal of an existing boiler, the following steps shall be followed with each
appliance remaining connected to the common venting system placed in operation, while the
other appliances remaining connected to the common venting system are not in operation.
(a) Seal any unused openings in the common venting system.
(b) Visually inspect the venting system for proper size and horizontal pitch and determine
there is no blockage or restriction, leakage, corrosion and other deficiencies which could
cause an unsafe condition.
(c) Insofar as is practical, close all building doors and windows and all doors between the
space in which the appliances remaining connected to the common venting system are
located and other spaces of the building. Turn on clothes dryers and any appliance not
connected to the common venting system. Turn on any exhaust fans, such as range
hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate
a summer exhaust fan. Close fireplace dampers.
(d) Place in operation the appliance being inspected. Follow the lighting instructions. Adjust
thermostat so appliance will operate continuously.
(e) Test for spillage at the draft hood relief opening after 5 minutes of main burner operation.
Use the flame of a match or candle, or smoke from a cigarette, cigar or pipe.
(f) After it has been determined that each appliance remaining connected to the common
venting system properly vents when tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other gas-burning appliance to their previous
condition of use.” (g) Any improper operation of the common venting system should be
corrected so the installation conforms with the National Fuel Gas Code, ANSI Z223.1
and/or CAN/CGA B149, Installation Codes. When resizing any portion of the common
venting system, the common venting system should be resized to approach the minimum size as determined using the appropriate tables in Part 11 of the National Fuel Gas
Code, ANSI Z223.1 and/or CAN/CGA B149, Installation Codes.

9.1 Fitting the flue system:
In general, it has to be taken in consideration that the horizontal sections of the flue
pipe must have an horizontal sloping not less than 1.5 degree (0.3 in per ft) towards the
boiler.
In the standard horizontal flue kit the flue pipe is angled within the air duct therefore the air duct
must be horizontally installed.
If one or more extensions have to be used they must be adequately supported so that there
is no sag in the flue pipe and a minimum fall of 1.5 degree (0.3 in per ft) over the whole length
towards the boiler is ensured.
9.2 Choice of flue:
The following flue kits are available for connecting to the boiler:
A

towards the floor and cap to form a sediment trap (E). Install a shut off valve (A) before the tee
with sediment trap and a union after the tee before the combination gas valve (D).
When installing the boiler, make sure a pipe compound resistant to the action of liquefied petroleum is used. Check piping for leaks. Always check leaks with a water and soap solution.
The boiler and its gas connection must be leak tested before placing the boiler in operation.
The boiler and its individual shut-off valve must be disconnected from the gas supply piping
system during any pressure test in excess of ½ psi (3.5 kPa).

The hydraulic specification in Fig 13.1 represent the pressure (available head for the
central heating system) as a function of the flow rate. The pressure loss due to the internal piping in the boiler has already been substracted.
When determining proper piping of the heating system, verify that the internal boiler circulator
will overcome the head loss of the system at the designed flow rate using the graph above.
If the internal circulator is adequate, direct system piping can be utilized. See section 14 page
48 for suggested direct supply/return piping.
If the internal circulator is inadequate, a secondary circulator must be utilized. See sections 14
for suggested primary/secondary piping.
13.2 Expansion vessels:
The height difference between the C.h. PRV (1 on page 10) and the highest point in the system
may be 23 ft at most. For greater differences, increase the pre-load pressure in the C.h. expansion vessel (25 on page 11) and the system when cold, by 0.1 bar for additional 3.3 ft. For
systems with volumes greater than 39 gallons (154 L), an additional expansion vessel must
be provided.
RIVA ADVANCE SV MANUAL

14.Piping
All external piping components are to be supplied by the installer. It is very important to use a
primary secondary piping scheme when an external circulator will be used. Also, when the boiler
is piped in a primary secondary manner, it is necessary to use the central heating flow restrictor
supplied with the boiler. The flow restrictor ensures there will be enough back pressure to make
the central heating flow switch in a low head loss piping system like primary secondary.
Installation of flow restrictor: The flow restrictor is installed inside the pipe tail
that attaches to the boiler. Place the flow restrictor into the gasket for the central heating supply
pipe tail. Place the gasket on the pipe tail so the
flow restrictor seats into the pipe tail. Then install
the pipe tail onto the boiler.
There are two methods for accomplishing a primary secondary piping system. The first is to
use two closely spaced tees for the boiler supply and return. An example is shown below in
Figure 14.1. The run legs should be sized so that there is no excessive head loss on the external circulator that is installed. In most circumstances 1 ¼” piping will be the best choice. When
the boiler is piped in this way, the external circulator will not have any hydraulic effect on the
Riva Advance SV. This is essential to ensure that the flow switch will operate properly.

15.1 For proper system operation, make
sure that:
• System filling and top ups will be done
using softened water to reduce the total
hardness. The water must also be conditioned in order to keep the pH within the
foreseen threshold in order to prevent
corrosion (see the following table).
• Both for new systems as well as when
replacing, the system must have efficient
systems that eliminate air and impurities
up to 5 μm (for ex: Y filters, micro impurity
separators and micro air bubble separators);
• Avoid draining system water during ordinary maintenance, even apparently insignificant quantities: for example, when
cleaning the filters, provide the system
with suitable shut-off valves;
• Always analyze the system water before
opening the communication between the
new generator and the system in order
to determine if the parameters of the water indicate the need to completely drain
the system, to use the water already
contained in the system or to chemically
wash the system, using mains water with
the addition of detergent, when it is suspected that the system could be dirty or
particularly blocked, and the next time
new water is loaded. If the analysis of a
sample of the water that will be used for
loading the system shows the following
values, the system can be used. Otherwise, an inhibitor must be used.
9,6 < pH < 10,5
Ca++ + Mg++ : <0,5 °F
OH + 1/2 CO3 : de 5 à 15 °F
P2O5 : de 10 à 30 mg/l
Na2SO3 : de 20 à 50 mg/l
If the system water is also in contact with aluminum, a pH value <8.5 is required.
