7.3 Maintenance Works on gas components and electrical installation may only be carried out by authorised personnel. We recommend to contact your Dometic Service Centre. EN 1949 stipulates that the appliance´s gas equipment and it’s associated fume system must be inspected after installation and a certificate issued. Afterwards a qualified technician must inspect according to EN 1949 every two years and a certificate issued. It is the user’s responsibily to arrange for inspections after purchase.
8.0 INSTALLATION GUIDE On installation of the appliance, the technical and administrative regulations of the country in which the vehicle will first be used must be adhered to. Otherwise the refrigerator must be installed as described in these instructions. In Europe, for example, gas appliances, cable laying, installation of gas cylinders, as well as approval and checking for leaks must comply with EN 1949 for liquid gas units in vehicles. 8.
8.1.2 Rear installation causesatan unfavourable installaIfRear the installation refrigerator often is mounted the rear of the vehicle tion arrangement, as ideal ventilation cannot always be unit. assured (e.g. the lower ventilation grille is covered by the bumper or the rear lights of the vehicle!) (Fig. 4). The maximum cooling performance of the aggregate is actually not available. Fig.3 Another variant of the rear installation is the side installation of the ventilation grilles (fig. 5).
8.3 Draught-free installation Refrigerators in motorhomes, caravans or other vehicles must be installed in a draftproof manner (EN 1949). This means that the combustion air for the burner is not taken from the living area and that exhaust fumes are prevented from entering the living area . In no case, use sealing material or foam, in order to build in the fridge draught-free.
If the cavity between the caravan wall and the refrigerator is sealed so that fumes cannot penetrate the living area it is possible to vent the flue gas directly through the upper grille without using the aluminium flue pipe. The waste gases escape to the outside through the upper grill of the ventilation. Do not use any kind of aluminium flue pipe (e.g. T-piece) to lead the flue gas out. The flues of the oven escape to the outside through the roof ventilator.
