Nefit ProLine NxT HRC 24/CW4
All gas technical measurements for GAD have been performed by Bosch Thermotechniek under their lab
acknowledgment with Kiwa. Spot-checks tests have been witnessed by a Kiwa Test Engineer
The Bosch test results are not part of the Kiwa ISO/EN 17025 accredited test report, although the Bosch
test results can be determined as equal to the EN 17025 level. The Bosch test results are used for verifying
to show compliance to the essential requirements of the GAD (2009/142/EC). The Bosch test results can
be found in folder B_suppliers information, test results manufacturer.
The appliances have also been tested on gas group K according Dutch regulation NTA 8837:2012. Not all
gas technical tests have been performed. See folder B_suppliers information, test results manufacturer for
justification of adjusted test program.
The EMC and electrical safety tests were performed by Kiwa on the ProLine NxT HRC 24/CW3. The
ProLine NxT HRC 24/CW3 and ProLine NxT HRC 24/CW4 are almost identical. The appliances only differ
in maximal DHW load and DHW flow limiter. On these aspects the HRC24/CW3 is representative for the
HRC24/CW4 as well. The electrical safety and EMC test reports are therefore valid for both appliances.
The determination of the maximum flue gas length has been performed by Muelink & Grol and was
witnessed by Kiwa. Used instruments are under calibration of Kiwa. The M&G test results can be found in
folder B_suppliers information, test results manufacturer and are not part of the Kiwa ISO/EN 17025
accredited test report.
The Proline NxT is equipped with a back flow valve which enables it to be connected to overpressure flue
systems, just like its predecessor ProLine I. The back flow valve is identical to the one used in the ProLine I
CW5, only the angle of the housing changed 10°. The back flow valve was tested by Bosch according the
DVGW G635 standard.
A 24 hour overpressure CLV test has been performed by Bosch Thermotechniek to see whether an unsafe
situation with the appliance can occur. Condensation was formed in the housing of the gas boiler, but this
did not lead to an unsafe condition. The test has been witnessed by Kiwa.
Bosch decided to use the same flue gas and air intake duct diameters for CLV systems for the ProLine NxT
as for the ProLine I. The ProLine NxT uses higher fan speeds than the ProLine I. Thus the flue pressure is
higher at a 5% reduced load. Because of that longer flue lengths can be used for CLV systems with the
ProLine NxT. The ProLine I was already approved for CLV systems by DVGW (see CE certificate
ProLine I). Kiwa checked and concluded that in the installation manual for CLV systems of the Proline I and
ProLine NxT the same flue gas/air intake diameters are used.
See folder B_suppliers information, CLV flue systems data and measurements for the test results and
further data.
Bosch Thermotechniek has made an analysis for justification of the use of plastic flue gas material which
has not been tested according EN14471. The justification for its use can be found in folder B_suppliers
information, justification plastic flue gas material.
Measurements according tapping cycle S and M with the EN13203-2 method have been carried out by
Bosch Thermotechniek. The test results can be found in folder B_suppliers information, test results
manufacturer and are not part of the Kiwa ISO/EN 17025 accredited test report.
The Gaskeur test report number is 131101861GK.
Based on the product(s) information the test plan is not subject to any special interpretations or
modifications.
