PRODUCT DESCRIPTION
SUNDAY 30/130 B
condensing boilers are high efficiency,
low temperature boilers for the production of hot water
for central heating, and also for domestic hot water in
conjunction with a 137 litre storage cylinder.
SUNDAY
30/130 B
boilers incorporate a low water content, low
pressure drop, compact, monobloc, aluminium heat
exchanger, and a premixed microflame 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 surface,
thus minimising emissions, maximising combustion effi-
ciency and improving ignition reliability.

boilers come complete with safety valves, vent valves,
expansion vessels, drain cocks, system fill cocks and
pumps for the central heating circuit and storage cylinder.
In their basic configuration, these boiler can serve one
direct (high temperature) central heating circuit and
one mixed (low temperature) circuit via a temperature
controlled mixer valve. A further low temperature circuit
can be served with the addition of the relevant multi-zone
accessories. See the 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 .
The main technical characteristics of

and ensure the safety of the entire system (with error
display requiring reset by OFF-RESET button).
- 3 bar central heating circuit safety valve.
- 8 bar domestic hot water circuit safety valve.
b
The intervention of a safety device indicates a
potentially dangerous malfunction in the system,
and means that you must contact the 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 the Technical
Assistance Service using original spare parts.
Always check that the boiler is functioning correctly after
any repairs.
The boiler is fitted with the following safety devices:
