CUENOD burner technology:
NC.4R - NC.4 - NC.6 - NC.9.
Rising to users' expectations.
Having acquired a wealth of experience
through our work with professionals in
the field, we have produced a new
generation of burners that combine
improved performance, precision and
reliability.
These burners are designed,
developed and built in compliance with
European Standards EN 267 for
burners and EN 29002 (ISO 9002) for
manufacture.
CUENOD burners are manufactured in
compliance with the quality assurance
certificate AFAQ ISO 9002.
Burner ventilation: NC.4R NC.4 - NC.6 - NC.9:
the RHP® system.
Modern boiler technology and a
significant number of older generators
led us to create a new ventilation
system to enable burners to adapt to all
situations.
The air-flow system of burners
equipped with the High Performance
Recycling (RHP®) system patented by
CUNEOD allows:
combustion stabilization during
• faster
startup,
• reduced boiler clogging,
• reduced pollution emission,
quiet operation (isolated
• extremely
air flow system),
sensitivity to fluctuations in
• reduced
chimney draw,
output between 90% and
• thermal
93%, depending on the type of
boiler.
Performance is further enhanced
through the use of an independent air
valve that cuts off draw when the
burner is turned off, irrespective of the
position.
The RHP® system and advanced air
register placed on the discharge ensure
continuous high pressure.

A significant reduction of successive

All controls and displays are grouped
together on the control panel to provide
easy access.
➀ Air flow adjustment.
The air register is designed to enable
linear adjustment:
the air flow is proportional to the
included angle and the 180° adjustment
range provides increased accuracy.
➁ Combustion head adjustment.
The position of the baffle in relation to
the end piece is shown by a micrometric
value on the control panel.
This feature has been patented by
CUENOD.
Settings values can easily be read
during maintenance.

Operating Data Memorization.
Burners are equipped with an
innovative operating system that may
be consulted at any time.
The system provides two types of data:
1 - "Instantaneous" information
- Burner startup cycle
- Power supply measurement
- Flame signal measurement.
2 - "Stored" information
- Burner operation data, including
total operating time
- Conditions of use procedures.
This information, available in real time,
can be exported and referenced using a
laptop computer running CUENOCOM
software. The information can then be
sent to the operating system to facilitate
maintenance.
