CEN/TC 180/WG 3 - Non-domestic, indirect gas-fired air heaters

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 B22, B23, B52, B53, C12, C13, C32, C33 C52 and C53 appliances intended for use in other than domestic dwellings, in which 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 B22, B52, and C52 appliances intended for use in other than domestic dwellings, in which the supply of combustion air and/or the evacuation of the products of combustion is achieved by mechanical means.
This standard also includes appliances incorporating a secondary heat exchanger in the flue system.
This standard 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 standard is applicable to appliances which are intended to be type tested.

This European Standard specifies the requirements and test methods for the construction, safety, classification and marking of non-domestic gas-fired overhead radiant tube systems incorporating two or more burner units with each burner under the control of an automatic burner control system, and operated by a single fan providing a single flue outlet, called system H and referred to in the body of the text as the “system”.
This standard is applicable to Type B52 systems (see 4.3) intended for use in other than domestic dwellings, in which the supply of combustion air and the evacuation of the products of combustion is achieved by mechanical means. This standard is applicable only to such systems that have fully pre-mixed gas/air burners.
This standard is not applicable to:
a)   systems designed for use in domestic dwellings;
b)   outdoor systems;
c)   systems of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference test gas);
d)   systems having a draught diverter;
e)   systems that are designed for continuous condensation within the flue system under normal operating conditions;
f)   systems having combustion products evacuation ducts that are non-metallic.
This standard is applicable to systems which are intended to be type tested. It also includes requirements concerning the evaluation of conformity, including factory production control, but these requirements only apply to POCEDs and their associated terminals.
NOTE   Requirements for systems which are not intended to be type tested would need to be subject to further consideration.
Requirements concerning the rational use of energy have not been included in this European Standard.

This ENV specifies the requirements and test method C for the rational use of energy of a non-domestic gas-fired overhead radiant tube heater incorporating a single burner, or of a non-domestic gas-fired fixed overhead luminous radiant heater, referred to in the body of the text as an "appliance", with a reference surface as defined in 3.1.

This ENV contains the requirements and test method B for the rational energy saving of radiant heaters and plaque heaters for commercial and industrial application described in the following text as "heaters" with a defined radiant reference level, defined in paragraph 3.
