Riva Plus Manual
9
The Riva Plus 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
49476 BTU/h to 116008 BTU/h. The boiler is shipped fully assembled with the components
listed on page 11. 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
