PURPOSE:To provide a catalyst case which can be adapted for any type of combustion units by a method wherein fitting part for the ignition unit is arranged at one belt-like piece of the fitting hardwares and longitudinal holes to be engaged with -shaped projections of a main body of the catalyst case are made in the other belt-like piece. CONSTITUTION:In order to assemble a fitting hardware 1 with a main body 2 of a case, at first a catalyst 11 is fixed to the main body 2 of the catalyst case. At this time, it is the simplest process to place and fix the catalyst on the projections 4 of the catalyst case. Then, the fitting hardwares 1 are fixed. The fitting hardwares 1 are inserted in such a way as they are in parallel with T-shaped projections 3 of the main body 2 of the catalyst case and then they are rotated by a degree of 90 deg.. With this arrangement, the pieces 6 having longitudinal holes 9 of the fitting hardwares are fitted inconcave parts 5 of the T-shaped projections 3 and can be moved in a direction of arrow X, however, they may not be out of the main body. With this arrangement, the position of the fitting holes 10 for the top plate can be varied freely, resulting in that the catalyst case can be fixed to any types of petroleum stoves. |
