  • Page 2: Stove Operation

    Technical information Stove operation The 88DU is a safe diesel stove with no open fl ame. The stove is equipped with a single burner which burns either diesel oil or light furnace oil. The stove takes the air needed for the burning process from the boat and discharges the resultant smoke with a combustion air blower.

  • Page 3: Things To Note When Selecting The Installation Location

    Moreover, the stove should not be installed on top of a refrigerator. The stove will heat its surroundings and thus decrease the power of the refrigerator. We recommend that the device be installed by an authorised Wallas service shop. Things to note when installing pipes, hoses and cables Power cables and fuel hoses must be protected in locations where they are sus- ceptible to mechanical damage due to sharp edges or heat.

    88DU Installation Fastening the device Place the stove in the installation cut-out and attach the iron fasteners (3) with the screws (5) to the rivet nuts at the ends. After this, install the cover plug (8) on the end of the screw and tighten the iron fasteners against the table with the screw (6).
  • Page 7 88DU Installation Installation of the fl ue gas pipe Measure the length of the fl ue gas and exhaust pipe from the device to the gas lead-through. Remember to add the required length for the swan neck section. Cut the fl ue gas pipe 30–50 mm longer than the exhaust pipe. This way the pipe will stay in place in the gas lead-through more fi...

  • Page 8: Electrical Connections

    88DU Installation ELECTRICAL CONNECTIONS Things to note about the connections The device uses 12V direct current voltage. To minimise current losses, make the power cable as short as possible and avoid jointing. The cross-sectional area of the cable is dependent on the length of the power cord. See table 1. The cross- sectional area of the cable must be consistent all the way from the stove to the battery.

  • Page 9: Electrical Connections Of The Device

    88DU Installation Electrical connections of the device 12V direct current system Connect the red wire of the power cord to the plus terminal of the battery and the black or blue wire to the minus terminal. A 15 A main fuse must be installed near the battery on the red plus wire of the power cord.

  • Page 10: Fuel Connections

    88DU Installation FUEL CONNECTIONS Things to note about the connections The standard length of the fuel hose is 4 m (max 8 m). Cut the fuel hose to a length suitable for installation. The lift height of the pump should be less than 2 m; preferably 0.5 – 1 m.

    88DU Installation Tank-external fi lters Filters can be installed in a ø5 or ø6 mm plastic or ’’ metal pipe. Ensure that the fuel pipes are clean before installing the fi lter. There must be no debris or impurities between the pump and the fi lter as they will clog the pump. The fi lter type must be selected according to the operating conditions and country-specifi...
  • Page 14 88DU Installation Installation instructions for Solenoid valve 30012 (accessory) The solenoid valve (30012) prevents the tank from emptying in case the fuel line breaks. The fuel fi lter should be installed before the solenoid valve. In a fuel hose with a T branch, the solenoid valve must function with both connect- ed devices.

  • Page 15: Selecting The Fuel

    88DU Installation Selecting the fuel When selecting the fuel type, take note of the temperature limits of each particular fuel. The limit values provided here are to be treated as guidelines. Confi rm the actual temperature limits from the fuel supplier.

  • Page 17 88DU Installation SPECIFIC INSTRUCTIONS FOR INDIVIDUAL LEAD-THROUGHS 2467 Side lead-through A side lead-through is installed in the side of the boat or in the transom. In sail boats it is recommended to install it in the transom. The installation always requires a so-called swan neck piece.
  • Page 18 88DU Installation 3468 General lead-through You can install the general lead-through in a position of your choice, but ideally the lead-through is installed in a position which allows it to function optimally. 1. If the lead-through is installed in the side of the boat or a deck structure, it should be slightly inclined towards the stern so that the outer surface of the lead-through will be cooled by the thermal current going through it as well as the wind.
  • Page 19 88DU Installation 2460 Closable lead-through The cap of the closable lead-through must be detached for installation and seal maintenance by pressing the spring indicated by the arrow in with, for instance, a screwdriver. Take care not to let the screwdriver slip as the spring is very stiff. Hold the cap with your other hand when pressing in the spring.
  • Page 20 88DU Installation Insulation kit for a metal-hulled boat An insulation kit must be used to insulate the lead-through from the boat’s metal hull. The insulation kit insulates the fl ue gas lead-through and the device from each other. In fault situations the electric circuit runs between the metal hull and the device.
