Built in appliances are installed in accordance with the instructions. Other heating appliances and other combined appliances are placed in a test corner as follows:
– Appliances normally placed on a floor or table in use, are placed on the floor as near to the walls as possible;
– Appliances normally fixed to a wall are fixed to one of the walls, as near to the other wall and floor or ceiling as is likely to occur, taking into account the instruction;
– Appliances normally fixed to a ceiling are fixed to the ceiling as near to the walls as is likely to occur, taking into account in the instructions.
Dull black-painted plywood approximately 20 mm thick is used for the test corner, the supports and for the installation of built-in appliances.
Thermocouples having wires with a diameter not exceeding 0.3 mm are considered to be fine-wire thermocouples. Thermocouples used for determining the temperature rise of the surface of walls, ceiling and floor of the test corner are attached to the back of small blackened disks of copper or brass, 15 mm in diameter and 1 mm thick. The front of the disk is flush with the surface of the board.
