specific requirements, as well as the local availability of certain makes an mo els of controls

an accessories. The prece ing oes not apply, however, to the equipment that comes with

every boiler, such as the overheat control an 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.

DANGER

Riva Plus Manual 7

Any appliance that burns natural gas, propane gas, fuel oil, woo or coal is capable of

pro ucing carbon monoxi e (CO). Carbon Monoxi e (CO) is a gas which is o orless,

colorless an tasteless but is very toxic. CO is lighter than air an thus may travel

throughout the buil ing.

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 inclu e the following:

izziness vision problems shortness of breath

hea ache loss of muscle control unclear thinking

nausea weakness unconsciousness

The symptoms of CO poisoning are often confuse with those of influenza, an the

highest inci ence of poisoning occurs at the onset of col weather or uring 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 in icate the presence of carbon monoxi e:

If any of the symptoms of CO occur, or if any of the signs of carbon monoxi e 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

Riva Plus Manual 9

The Riva Plus is a high efficiency con ensing, wall mounte gas boiler which provi es central

heat. The boiler features a gas valve which mo ulates the energy input from

49476 BTU/h to 116008 BTU/h. The boiler is shippe fully assemble with the components

liste on page 11. All units are pressure an combustion teste at the factory prior to

shipping.

Key Features:

• Wall mountable - saving valuable

floor space.

• Several flue options available

• Electronic spark ignition

• Safety flow switch - positione on

the main circuit, which monitors the

flow an protects the main heat

exchanger from thermal shock

shoul there be a lack of water in

the system.

• Frost protection - contains an

integral frost protection system to

prevent frost amage which can

occur in areas susceptible to very

col weather con itions.

• Boiler operation recognition system

- shoul the boiler not be use for

longer than 24 hours, it then

performs a controlle system test

to ensuring the motorize

components within the boiler o not

become inoperable ue to lack of

use.

• Gas valve mo ulation - the gas

input mo ulates base off central

heating temperature to within ± 2 ºF

• Diagnostic information system

equippe with three LED iagnostic

lights for quick error assessment
