The glass on the Arte 3RL-80h-4s can be easily opened in the traditional way for easier cleaning on the inside. 4S: Printed black silhouette edge on the glass on 4 sides. The insert is clean-burning and tested according to the Norwegian special requirements (NS 3059). The Spartherm Varia AS-3RLh fireplace insert has an energy label of A+ and a nominal output of 8.4 kW.
