<p>A support mechanism of the electric resistance in the heater/boiler which consists of the cap (2), FIG. 4.,the tubular bolt (7), which is fastened at the center of the cap (2) around the opening (3) in such away that it nestles outside the cord (or rim) (X). The rubber flange (10) is placed on the cord (X), the metal flange (4) with the electric resistance (5) and the magnesium rod (6) on the rubber flange. Then the externally threaded tubular nut is manually screwed into the internally threaded bolt until the lower surface of the of the tubular nut touches the metal surface of the electric resistance (4). In turn, a metal rod is inserted into the opening and the tubular nut is turned until it tightens completely the metal flange (4) of the electric resistance with the rubber flange (10). In ths way we have secured the electric resistance and at the same time we have hermetically closed the opening (3) of the cap (2) of the heater/boiler (1).</p> |
