Abstract: A Grill-Unit is described, preferably for charcoal burning, with a coal duct with a vertical U cross sectional form and lateral air vents, a grease trap tray inserted into the ducts' outer walls, with tapering guide walls rising upward from the ducts' outer walls to form a cover. The upper portion of the cover has vertical air trap walls, which form a grid conduit upon the base of which the grating is located. The main points are, that two parallel with one another extended coal ducts (3) are arranged at the bottom of the Grill-Unit, and that both coal ducts sit in between a vertical back wall (1) and a removable front wall (20) parallel to the vertical wall. By removing the front wall during operation of the unit, access to the inner portion of the unit is possible if desired, for example the grease trap tray (11) may be emptied, spices and sauces may be brought in, and as well the coals may be stirred about, since they are also layed out in the coal duct box-form, in a special design.
