<p>The radiator has a rectangular frame with a front plate (1), side plates(11) and a back plate leaving the top and bottom open. There is an electric heater within the casing formed by the frame and the controls can be mounted on the front plate. The open top and bottom are completed by grilles(4). The grilles are made in sections of shorter length than the length of the whole radiator. Several sections are put together longitudinally to form the complete run of grille. This enables a small number of standard grilles to be used for a series of radiators of different sizes.</p> |
