Dear Customer:
Thank you for buying a Biasi Riva FP Boiler System.
The Riva FP 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 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 re-
alize that other makes and models of such devices are available and can be used as suc-
cessfully 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 spe-
cific 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 FP has been tested
to standard CSA 4.9 and is CSA compliant.
This Riva boiler 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 FP boiler. If you have questions or comments,
please don’t hesitate to contact us immediately. Our goal is 100% customer satisfaction.

RIVA FP 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 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 SER-
VICE COMPANY OR THE GAS COMPANY OR THE FIRE DEPARTMENT.
ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM WORK
ON YOUR BIASI RIVA FP BOILER.

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 Sec-
tion 15 Commissioning.
• Ensure that the Central Heating circuit is regularly filled with water checking that the pres-
sure 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 pur-
pose.
• If you are in any doubt regarding this procedure you are advised to contact your In-
staller 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 sec-
tion 5.6 on page 14.
5.2 Refilling procedure:
• Isolate the boiler from the electrical sup-
ply 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 auto-
matic 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.
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.

5. Instructions For Use Cont.
5.3 Lighting/Operating Instructions:
Warnings: Do not attempt to start the boiler unless all cleanout doors are secured and
sealed. Do not attempt to light the burner by hand.
1 Check that the cocks connected to the
gas inlet pipe and to the supply cold wa-
ter inlet pipe (see section 3.3 for pipes)
are open.
2 Turn on the electricity supply to the boiler,
switching on the circuit breaker. The appli-
ance operation light A (figure 5.2) will flash
every 4 seconds (stand-by condition).

The appliance operation light A will flash
every 2 seconds (operating boiler).
4 If the appliance will not operate, follow
the extinguishing instructions on page 14
and call your service technician or gas
supplier.
5.4 Central Heating Circuit Temperature:
1 The output temperature of c.h. water is
adjustable from a minimum of about 100
°F to a maximum of about 176 °F (Figure
5.3), by turning the knob B
2 Adjustment of the boiler temperature al-
ters 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 mini-
mum level for more or less long periods.
3 Adjustment of central heating. output on
the boiler is automatic. The greatest out-
put is factory pre-set, however, it can be
reduced according to actual system re-
quirements. These adjustments must be
carried out by a qualified person; there-
fore we advise you to contact your install-
er or Service Agent.
Figure 5.3

RIVA FP USER MANUAL 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 5.4
• Your installer may have installed addi-
tional 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 9) will allow you to check that
the set temperature is obtained.
Figure 5.4
5.5 Extinguishing Instructions:
• To turn the boiler off set the function se-
lector C to the position shown in the Fig-
ure 5.5.
• The appliance operation light A (figure5.2)
will flash every 4 seconds (stand-by
mode).

at the circuit panel of boiler serviceman’s
switch.
Figure 5.5
When you expect not to use the boiler for a long period:
• Switch off the electricity supply to the boiler, by means of the circuit breaker;
• Shut off the gas supply cock connected to the gas inlet pipe and the cock connected to the
supply cold water inlet pipe (see section 3.3 for pipes)
• Empty the water circuit, if necessary, as shown in the installation, operation and service
instructions manual in the maintenance section.

14 RIVA FP USER MANUAL
5. Instructions For Use Cont.
5.6 Domestic hot water temperature:
The temperature of the domestic hot water coming out from the boiler can be regulated from a
minimum of approximately 95° F to a maximum of approximately 131° F by turning the control
shown in fig. 5.6
Figure 5.6
Figure 5.7
Adjustment of the d.h.w. temperature is completely separate from that of the c.h. circuit.
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.
Regulate the domestic hot water temperature to a value suitable for your requirements.
Reduce the need to mix the hot water with cold water.
In this way, you will appreciate the characteristics of automatic regulation.
If the water is particularly hard, we recommend regulating the boiler at a temperature lower
than 120° F fig.
In these cases, we nevertheless recommend the installation of a water-softener on the domes-
tic hot water system.
If the maximum flow rate of the domestic hot water is too high for a sufficient temperature to be
reached, it is advisable to have a suitable flow rate limiter installed by an Authorised Assistance
Technician.

RIVA FP USER MANUAL 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 (C in Fig. 6.1).
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 central heating circuit.
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;
• burner;
• exhaust fume duct and flue;
• pressurization of the expansion vessel;
• filling up of the central heating circuit;
• bleeding of air from the central heating system;
• general check of the appliance’s operation.

16 RIVA FP USER MANUAL
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, abra-
sive powders or sponges.
• Do not carry out cleaning of the appliance and/or its parts with readily flammable substanc-
es (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 1
(Fig. 6.2) has stopped the boiler
• To re-start the boiler, it is necessary to
turn the function selector B in the position
and then press the boiler reset button
2 (Fig. 6.2).
• For the first light up and following main-
tenance 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.
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 9) 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 9) 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.

RIVA FP USER MANUAL 17
6. Useful Advice Cont.
If water comes out of the pressure relief valve pipe 3 in Fig. 6.3:
• Check on the temperature and pressure
gauge (figure 5.1 on page 9) 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 de-
crease 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.
Figure 6.3
If water should occasionally leak from the boiler:
• Close the cocks connected to the inlet gas pipe and to the supply 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 5.5 on page 15 and call a competent and responsible service person.
