Your attention is drawn to the requirement that those parts, which have been protected by the manufacturer or his agent, are not to be adjusted by the installer. These appliances are to be installed with sufficient ventilation to prevent the occurrence of unacceptable concentrations of substances harmful to health in the room in which they are installed. Before Installation Before commencing installation, remove all packaging materials from the appliance. It is suggested that any protective film adhering to the stainless steel panels should be left on until installation is completed. BUT THIS MUST BE REMOVED BEFORE COMMISSIONING OR OPERATING THE APPLIANCE. Check appliance Data Plate (located at the top rear of the appliance) to ensure appliance is correct for local gas supply. Note: - During installation, always employ accepted standards of gas fitting and National Water Council practices. Positioning and levelling: 1) Place steamer in position, allowing a minimum of 125mm (5 ) at the sides and 160mm (6 ) at rear for connection of gas and water supplies and ensure that there is a minimum distance of 1 Metre between the top of the appliance and any overhead ceiling or overhanging shelf. A minimum distance of 1 Metre must be allowed at the front of the appliance for door opening and unloading of food from the cooking compartment. Ensure that position of installation is free from draughts. 2) Using a spirit level, check the steamer is level in two planes. 3) If necessary, use levelling feet to bring appliance level. Turn anti-clockwise to lower or clockwise to raise appliance. Manual Part No: MV1 Gas Steamer - 8
