DIN EN 13278:2014-03

This European Standard specifies the requirements and test methods for the construction, safety, marking and rational use of energy of open fronted gas-fired independent space heaters with and without a fan to assist with the transportation of flue gases. Although the fan may be mounted outdoors, this standard only covers appliances where the body of the appliance is indoors. This standard applies to types B11AS, B11BS, B14AS, and B14BS open fronted gas-fired independent space heating appliances that incorporate an atmospheric burner, that are connected directly to an open flue or to a device to evacuate the products of combustion (open-flued appliances), that have a nominal heat input not exceeding 20 kW (based on the net calorific value) and that are delivered with the gas-carrying components, burner (s), combustion chamber and heat exchanger fully assembled.
