The Riva Combi is a high efficiency, non-condensing, wall mounted gas boiler which provides
central heat and domestic hot water. The boiler features a gas valve which modulates the energy
input from 44,000 BTU/h to 108,000 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 and
domestic hot water temperature to within ±
2 ºF
• Diagnostic information system equipped
with three LED diagnostic lights for quick
error assessment.
