1. General Information

The Riva Heat Only is a high efficiency, non-condensing, wall mounted gas boiler which provides central heat. 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 temperature to within ± 2 ºF

Diagnostic information system equipped with three LED diagnostic lights for quick error assessment.
