European foreword
This document (EN 17175:2019) has been prepared by Technical Committee CEN/TC 180
“Decentralized gas heating”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by month year of DOP, and conflicting national standards
shall be withdrawn at the latest by month year of DOW.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 416-1:2009, EN 416-2:2006 and EN 777-4:2009.
In comparison with the previous editions, the following technical modifications have been made:
— aspects of safety and energy efficiency of appliances are brought together;
— incorporation recent state of art of overhead radiant strips heaters and multi-burner continuous
radiant tube heater systems;
— unique and more detailed description of method to determine radiant factor;
— incorporating terms and calculation scheme of Ecodesign Regulation (EU) No. 2015/1188;
— minimum requirements of an optional flue gas heat exchanger.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

1 Scope
This document specifies the requirements and test methods for the construction, safety, classification,
marking and efficiency of non-domestic gas-fired overhead radiant strips heaters and multi-burner
continuous radiant tube heater systems (referred to in the body of the text as the “system”) with each
burner unit under the control of an automatic burner control system.
For radiant strip heaters incorporating a single burner, this standard is applicable to Type B , B , B ,
22 23 52
B , C , C , C , C C and C appliances intended for use in other than domestic dwellings, in which
53 12 13 32 33 52 53
the supply of combustion air and/or the evacuation of the products of combustion is achieved by
mechanical means.
For multi-burner continuous radiant tube heater systems this standard is applicable to type B , B , and
22 52
C appliances intended for use in other than domestic dwellings, in which the supply of combustion air
52
and/or the evacuation of the products of combustion is achieved by mechanical means.
This document also includes appliances incorporating a secondary heat exchanger in the flue system.
This document is not applicable to:
a) appliances designed for use in domestic dwelling;
b) outdoor appliances;
c) radiant strip heaters where the heat input is in excess of 300 KW (based on the net calorific value
of the appropriate reference test gas);
d) continuous radiant tube heater systems where the heat input of any individual burner unit is in
excess of 70 kW (based on the net calorific value of the appropriate reference test gas);
e) appliances having combustion products evacuation ducts that are non-metallic in the flue system –
except ducts downstream of a possible additional condensing exhaust gas heat exchanger.
In addition, for heater systems incorporating multiple tube heaters this standard is not applicable to:
f) appliances that are designed for continuous condensation within the flue system under normal
operating conditions – except downstream a possible additional exhaust gas heat exchanger.
This document is applicable to appliances which are intended to be type tested.
