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.
