gas, oil, wood or coal-operated heaters, continuous flow heaters or water heaters) obtain combustion air from the room in which they are installed and discharge the exhaust gases into the open through an exhaust gas system (e. a chimney). FD The numbers can be found on the rating plate inside the appliance (to do this, remove the metal-mesh grease filter). Enter the numbers in the above box so that you can easily find them when required. Installation Mortal danger, risk of intoxication! Due to combustion gases sucked back in. Never operate the appliance in the exhaust air mode at the same time as a room air-dependent heat-producing appliance unless an adequate supply of fresh air is ensured. 2 In combination with an activated vapour extractor hood, room air is extracted from the kitchen and neighbouring rooms - a partial vacuum is produced if not enough fresh air is supplied. Toxic gases from the chimney or the extraction shaft are sucked backed into the living space. Risk of injury, risk of damage! from objects falling on the appliance. Never place objects on the appliance. Risk of fire, risk of burns! if gas hotplates not covered with cooking utensils. Always use gas hotplates with appropriate cooking utensils. Regulate flame to ensure that it does not lick over the cooking utensil. Risk of burns, risk of damage! if several gas hotplates are operated simultaneously. Never operate two gas hotplates simultaneously on the highest flame for longer than 15 minutes. The housing will become very hot due to the intense heat. Note: One large burner of more than 5 kW (Wok) is equivalent to the power of two gas burners. Risk of fire! Adequate incoming air must therefore always be ensured. An incoming/exhaust air wall box alone will not ensure compliance with the limit...
