Introduction

The Biasi Riva OV 18 and Riva OV 30
effiency condensing, fully automatic, wall
mounted gas appliances suitable for room
sealed applications and for use with Natural gas
(G20) only. They are designed for use with either
sealed or open vented central heating systems.
The appliances incorporate a microprocessor
based, fully modulating pre-mix air/gas ratio
control system with direct burner ignition, which
provides a modulated heat output to central
heating (CH) demand.
The heat exchanger is constructed from
stainless steel, and there is the option for routing
the flow and return connections either via top or
bottom connections.
The appliances may be used with any certified
mains voltage room thermostat, and can operate
without the need for an automatic bypass valve,
however if thermostatic radiator valves are
installed it is recommended that one radiator is
fitted with lockshield valves, (normally in the
bathroom), to allow the pump overrun facility to
operate correctly.
