Dear Customer:
Thank you for buying a Biasi Riva Combi Boiler System.
The Riva Combi is a high efficiency, non-condensing, wall mounted gas boiler which
provides central heat and domestic hot water.
We realize that it is not possible to answer all questions about the Riva Combi boiler
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 Combi
has been tested to standard CSA 4.9 and is CSA compliant.
This Riva Combi 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.

DANGER
RIVA COMBI USER MANUAL - REV A 5

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.
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.
• Stale or smelly air.
• The presence of soot or carbon in or
around the appliance.
• Very high unexplained humidity inside
the building.

5. Instructions For Use
5.1 Warnings:
• In order to guarantee safety and correct operation, it is essential that all the tests are
carried out by a competent and responsible licensed service person before lighting up
the boiler.
• The tests are described in the installation, operation and service instructions manual in
Section 15 Commissioning.
• Ensure that the Central Heating circuit is regularly filled with water (even if the boiler is
only used for d.h.w. supply) checking that the pressure indicated on the temperature
and pressure gauge (4 on figure 3.2) is not lower than 1 bar (14.5 psi) as shown on
figure 5.1.
• If the pressure reading on the pressure gauge is below 1 bar (14.5 psi), then the
system will require filling. An automatic filling valve is normally provided by the installer
for this purpose.
• If you are in any doubt regarding this procedure you are advised to contact your
Installer or an Approved Service Person.
• This appliance is provided with a built in anti-freeze system that operates the boiler
when the temperature is below 41 °F
• Therefore, when the boiler is not lit or used in cold weather, with consequent risk of
freezing do not switch off the boiler at the circuit breaker or close the gas inlet
cock.
• When you expect not to use the boiler for a long period follow the instructions given in
section 5.6 on page 15.
5.2 Refilling procedure:
• Isolate the boiler from the electrical
supply at the circuit breaker.
• The boiler should have been installed
with an automatic fill valve, external to
the unit. Open the cold water supply
to the automatic fill valve.
• The pressure should be 1 – 1,5 bar
(14.5 – 22 psi).
• The automatic fill valve should
maintain this pressure, but not exceed
it.
0 42
31
Figure 5.1
Air introduced into the boiler during this filling process will vent through the automatic air
purger fitted to the boiler. You may also find it necessary to vent air from your heating
circuit using the installed vents, however be aware that excessive venting will cause the
pressure in the system to drop. Always ensure that the pressure gauge is set at the
required pressure.

is adjustable from a minimum of
about 100 °F to a maximum of about
176 °F (Figure 5.5), by turning the
knob 8
2 Adjustment of the boiler temperature
alters the gas flow at the burner
according to the thermal demand in
the system. So it is usual to see the
burner lit at the minimum level for
more or less long periods.
3 Adjustment of central heating. output
on the boiler is automatic. The
greatest output is factory pre-set,
however, it can be reduced
according to actual system
requirements; this does not affect
the maximum output in d.h.w.
operation. These adjustments must
be carried out by a qualified person;
therefore we advise you to contact
your installer or Service Agent.
Figure 5.5
RIVA COMBI USER MANUAL – REV A 13

5. Instructions For Use Cont.
Adjustment:
• In order to achieve optimal settings for
economy and comfort, we recommend
adjusting the operating temperature of
the central heating water according to
the outside temperature, positioning
the knob as in figure 5.6
• Your installer may have installed
aditional energy saving equipment
and will be able to recommend the
most suitable adjustment for your
system.
• The temperature and pressure gauge
(Fig. 5.1 on page 12) will allow you to
check that the set temperature is
obtained.
Lower than
23 °F
From 41 to 59 °F Between 23
and 41 °F
Figura 5.6
5.5 Domestic Hot Water Temperature:
• The temperature of the domestic hot
water (d.h.w.) leaving the boiler can
be varied from 100 °F to a maximum
of about 140 °F (Figure 5.7), by
turning the knob 8.
• The adjustment system integrated
within the boiler automatically controls
the flow of gas to the burner in order
to keep the temperature of d.h.w.
delivered constant, between the limits
of maximum and minimum output.
• Where the demand is at a low level or
with the temperature set to the
minimum, it is normal to see a cycle of
lighting and extinguishing of the
burner when running.

Figure 5.7
Adjustment:
• It is advisable to adjust the d.h.w.
temperature to a level commensurate
with the demand, minimising the need
to mix with cold water. In this way, the
automatic control facilities will be fully
exploited.
• Where the amount of limescale
present in the water may be
particularly great not exceeding the
position in Fig. 5.8 of the d.h.w.
temperature control knob 8, minimises
annoying incidences of scale deposits
and clogging.
• However it is advisable to install a
small water treatment device or
softener. With such a device you
should avoid periodic descaling.

service instructions manual in the maintenance section .
RIVA COMBI USER MANUAL – REV A 15

6. Useful Advice
6.1 Central Heating:
• For reasonably economical service
install a room thermostat.
• Never shut off the radiator in the area
where the room thermostat is
installed.
• If a radiator (or a convector) does not
heat up, check that no air is present in
it and that its valve is open.
• If the ambient temperature is too high,
do not alter the radiator valves.
Reduce the central heating
temperature instead by means of the
room thermostat and the knob (7 in
Fig. 6.1).
7
Figure 6.1
6.2 Frost Protection:
• The built in antifreeze system and any additional system protect the boiler from
possible damages due to the icing.
• This system doesn’t guarantee the protection of the whole central heating system.
• In the case that the external temperature may be lower than 32°F it is suggested to
leave the system running setting the room thermostat at a low temperature.
• When the boiler is completely switched off for a long period, it is recommended to
empty completely both central heating and domestic hot water circuits.
6.3 Periodic Maintenance:
• For efficient and continuous operation of the boiler, it is advisable to arrange
maintenance and cleaning by an Authorised Service Person, at least once a year.
• During the service, the most important components of the boiler will be inspected and
cleaned. This service can be part of a maintenance contract.
In particular, you are advised to have the following checks carried out:
• primary heat exchanger;
• magnesium anode;
• burner;
• exhaust fume duct and flue;
• pressurization of the expansion vessels;
• filling up of the central heating circuit;
• bleeding of air from the central heating system;
• general check of the appliance’s operation.
RIVA COMBI USER MANUAL – REV A 16

6. Useful Advice Cont.
6.4 External Cleaning:
• Before performing any cleaning, disconnect the appliance from the electrical mains,
using the dedicated circuit breaker or serviceman’s switch located adjacent to the
appliance.
• To clean the external panels, use a cloth soaked in soapy water. Do not use solvents,
abrasive powders or sponges.
• Do not carry out cleaning of the appliance and/or its parts with readily flammable
substances (for example petrol, alcohols, naphtha, etc.).
6.5 Operational Faults:
If the lock-out signal lamp comes on:
• This indicates that the safety lock-out
5 (Fig. 6.2) has stopped the boiler
• To re-start the boiler, it is necessary to
turn the function selector 7 in the
position and then press the boiler
reset button 6 (Fig. 6.2).
• For the first light up and following
maintenance procedures for the gas
supply, it may be necessary to repeat
the resetting operation several times
so as to remove the air present in the
pipework.
6
5
7
Figure 6.2
If noises due to air bubbles are heard during operation:
• You should check that the pressure on the temperature and pressure gauge(Fig. 5.1 on
page 12) is not below the correct setting.
• If required, fill up the system correctly, as described in the section 5.2 of this manual.
• Bleed any air present in the radiators, if necessary.
If the pressure on the temperature and pressure gauge (Figure 5.1 on page 12) has
gone down:
• It is necessary to fill up the appliance with water again, so as to raise the pressure to an
adequate level as described in the section 5.2 of this manual.
• If filling up with water has to be done very frequent, have the system checked for leaks.
If water comes out of the pressure relief valve 11 in Fig. 6.3:
• Check on the temperature and pressure gauge (page 12) that the pressure in the
central heating circuit is not close to 3 bars (43.5 psi). In this case, temperature rise in
the circuit can cause the pressure relief valve to open.
• So that this does not happen and to decrease the pressure to a normal value, it is
advisable to vent some of the water in the appliance through the bleed valves present
in the heating system.
RIVA COMBI USER MANUAL – REV A 17

6. Useful Advice Cont.
If water comes out of the storage tank pressure relief valve 10 in Fig. 6.3:
• This means that the pressure in the
domestic hot water circuit is more
than 8 bars (115 psi).
• To avoid this situation, it is advisable
to install a pressure reducing device
upstream of the domestic hot water
inlet valve.
• The pressure in the domestic hot
circuit should be lower than 8 bars
(115 psi).
10 11
Figure 6.3
If water should occasionally leak from the boiler:
• Close the cocks connected to the inlet gas pipe and to the domestic cold water inlet
pipe under the boiler and call an Authorised Service Person.
In case of problems other than those mentioned here, switch off the boiler, as
described in Section 5.6 on page 15 and call a competent and responsible service
person.
