delivery. These instructions should be
displayed in a prominent location at the
point of installation of the heat generator,
They should include the address and
telephone number of the nearest customer
service centre.

Important information
The NC29 and NC36GX207/8A burners
are designed for the low-pollutant
combustion of natural gas and propane
gas. The design and function of the
burners meet standard EN 676. They are
suitable for use with all heat generators
complying with standard EN 303 or for use
by hot air generators complying with
standard DIN 4794 or DIN 30697 within
their respective performance range. Any
other type of application requires the
approval of CUENOD.
Installation, start-up and maintenance
must only be carried out by authorised
specialists and all applicable guidelines
and regulations must be complied with.
Burner description
The NC29 and NC36GX207/8A burners
are 2-stage, fully automatic, monoblock
type burners. The special design of the
combustion head enables combustion with
low levels of nitrogen oxide and increased
output. Class 3 type-approval in
accordance with EN676 certifies that the
lowest emission values have been
achieved and means that the national
environmental regulations have been met
AT: KFA 1995, FAV 1997
CH: LRV 2005
DE: 1.BImSChV
Emissions values may differ, depending on
combustion chamber dimensions,
combustion chamber load and the firing
system (three-pass boilers, boilers with
reverse firing). For specifying warranty
values, the conditions for the measuring
equipment, tolerances and humidity must
be observed.
Packaging
The burner is supplied packaged in two
boxes on a pallet:
- Burner housing with operating
instructions, wiring diagram.
- Burner head with flange seal and
securing screws.
- Compact gas train with integrated filter
The following standards should be
observed in order to ensure safe,
environmentally sound and energy-
efficient operation:
EN 226
Connection of fuel oil and forced-draught
gas burners to a heat generator
EN 60335-1, -102
Safety of electrical equipment for domestic
use
Gas lines
When installing the gas lines and trains,
the general directives and guidelines, as
well as the following national regulations,
must be observed:
CH: - G1 instruction text from SSIGE
- EKAS form no. 1942,
liquefied gas directive, part 2
- Cantonal authority guidelines (e.g.
directives for the pilot valve)
DE: - DVGW-TVR/TRGI
Installation location
The burner must not be used in rooms with
aggressive vapours (e.g. hair spray,
tetrachloroethylene, carbon tetrachloride),
high levels of dust or high air humidity (e.g.
laundry rooms).
If no connection to an air exhaust system is
provided for the air supply, there must be a
supply air inlet measuring:
DE: up to 50 kW: 150 cm
2
per additional kW: : + 2.0 cm
2
CH: QF [kW] x 6= ...cm
2
; but at least
150 cm
2
.
Variations may arise as a result of local
regulations.
