PRODUCT DESCRIPTION
RESIDENCE COLONNA CONDENS
boilers are high effi-
ciency, low temperature boilers for the production of hot
water for central heating and domestic hot water systems.
They incorporate a 130 litre storage cylinder.
RESIDENCE COLONNA CONDENS
boilers incorporate
a low water content, low pressure drop, compact, mono-
bloc, aluminium heat exchanger, and a premixed micro-
flame burner controlled by an electronic control panel,
all enclosed within a robust free-standing casing. They
feature sealed combustion chambers and, depending on
what flue accessories are fitted, can be classed as B23P,
B53P, C13, C23, C33, C43, C53, C63 or C83 appliances.
The fan extracts flue gases and aspirates comburent
air from outdoors, and is continuously controlled by the
electronic control card.
The characteristics of the heat exchanger and burner
ensure an excellent level of performance.
The combustion chamber and the heat exchange area are
designed to keep temperature low over the burner sur-
face, thus minimising emissions, maximising combustion
efficiency and improving ignition reliability.
RESIDENCE
COLONNA CONDENS
boilers come complete with safe-
ty valves, vent and bleed valve, expansion vessels, drain
cocks, system fill cock and pumps for the central heating
circuit, storage cylinder.
More than one high or low temperature zone can be
heated, with the addition of the relevant multi-zone acces-
sories. See the
r
catalogue for details.
- autodiagnostics with display of error codes
- microprocessor control and display of NTC sensor
continuity
- 3-way valve anti-block function, activated automatically
after 24 hours from last movement
- pump anti-block function, activated automatically for 30
seconds, 24 hours after last pump cycle
- pressure transducer to prevent ignition in case of low
water pressure (with error display)
- flue gas temperature sensor to shut down the burner if
flue gas temperature exceeds the safety threshold
- condensate drain siphon with float system to prevent
the escape of fumes
- condensate level sensor to shut down the burner if the
condensate level in the heat exchanger exceeds the
safety threshold
- first level of frost protection (for indoor systems) func-
tional even with the boiler in standby, activated when
water temperature drops below 7°C
- Maximum temperature thermostat to detect overheating

b
The intervention of a safety device indicates a
potentially dangerous malfunction in the system,
and means that you must contact
r
’s Technical
Assistance Service immediately.
a
Never start the boiler up even for a short period if
the safety devices are not functioning correctly or
have been tampered with.
b
Safety devices must only be replaced by
r
’s
Technical Assistance Service using original spare parts.
Always check that the boiler is functioning correctly after
any repairs.
RESIDENCE COLONNA CONDENS
boilers are equipped with the following main safety devices:
