INSIEME CONDENS
boilers are high efficiency, oil fuelled
condensing boilers. “B” models are designed for heating
only. “BK” models come with a 120 litre vitrified storage
cylinder and are designed for combined heating and do-
mestic hot water production.
These boilers may be used as type “C” boilers if fitted
with a specific accessory kit to extend the comburent air
inlet to draw in air from outside the room where they are
installed.
The single stage jet burner is fitted with a fuel oil pre-heat-
er to ensure dependable functioning under all conditions.
The most important technical features of these boilers are:
- The combustion chamber and heat exchange system
are specially designed and shaped to achieve the best
possible volume to surface area ratio.
- The primary heat exchanger features vitrified steel
pipes and wave turbulators to recover and transfer a
large proportion of the thermal energy carried by the
combustion fumes.
- The secondary heat exchanger is made from AISI 904L
stainless steel and recovers latent heat from the flue
gases, boosting efficiency to up to 101.4 % (50°C –
30°C range).
- The horizontal vitrified storage cylinder incorporates a
vertical primary heat exchanger coil.
The exclusively designed heat exchange unit and sec-
ondary exchanger are insulated by ultra-efficient high
density glass wool. The controls and safety devices of the
electromechanical control panel conform to all applicable
technical and safety standards.
A specific accessory kit is available to control a high tem-
perature central heating circuit. Additional controllers can
also be added to manage additional direct/mixed circuits
or to integrate the boiler with
r
solar water heating
systems.
PRODuCT DESCRIPTION
SAFETY DEVICES
INSIEME CONDENS
boilers are equipped with the following safety devices:
-
A safety thermostat
that forces the boiler to perform
a safety shutdown if temperature exceeds the safety
threshold (110°C).
-
A flue gas thermostat
in the bottom of the secondary
heat exchanger that signals an error if flue gas tempera-
ture exceeds 90°C.
-
A burner safety system:
The oil burner is equipped
with an electronic controller that monitors the correct
functioning of the selected program. In the event of an
error, this controller displays a burner lockout signal on
the control panel.
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.
You may attempt to restart the boiler after a short delay
(see preparing for initial start-up).
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. Refer to the spare parts catalogue supplied
with the boiler.
Always check that the boiler is functioning correctly after
any repairs.
