2 RIVA ADVANCE COMBI MANUAL

Dear Customer:

Thank you for buying a Biasi Riva Advance Combi.

The Riva Advance Combi is a high efciency 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 Combi 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 qualied, 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 satised with your boiler and its performance. We require that your contractor complete

efciency 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 specic 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 specic 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 specic 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 Combi

has been tested to standard ANSI Z21.13/CSA 4.9 and is CSA compliant.

This Riva Advance 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 afxed to the boiler), date of installation

and the name of your installer being on record in our les.

Thank you for purchasing our Riva Advance Combi. If you have questions or comments, please

don’t hesitate to contact us immediately. Our goal is 100% customer satisfaction.

WARNING

Boiler is certied as an indoor appliance. Do not install boiler outdoors or locate where it will

be exposed to freezing temperatures.

— Do not store or use gasoline or other ammable vapors and liquids in the

vicinity of this or any other appliance.

— WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electric switch; do not use any phone in your building.

• Immediately call your gas supplier from a neighbor’s phone. Follow the

gas supplier’s instructions.

• If you can not reach your gas supplier call the re department.

— Installation and service must be performed by a qualied installer, service

agency or the gas supplier.

WARNING: If the information in this manual is not followed

exactly, a re or explosion may result causing property

damage, personal injury or loss of life.

DANGER

Caution: Do not store or use ammable materials, chemicals or ammable liquids,

especially gasoline, in the vicinity of this heating appliance.

Caution: Should overheating occur or the gas supply fail to shut off, do not turn off

or disconnect the electrical supply to the pump. Instead, shut off the gas supply at a

location external to the appliance.

Caution: Do not use this boiler if any part has been under water. Immediately call

a qualied service technician to inspect the boiler and to replace any part of the

control system and any gas control which has been under water.

6 RIVA ADVANCE COMBI MANUAL

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 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 COMBI.

1. General Information

2. Technical Information (M210.32 CM)

The Riva Advance Combi 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 with the components

listed on pages 10-11. 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 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.
