The minimum height from the base of the appliance to the underside of combustible materials used to construct a utility shelf in this fashion is shown in the Table in Figure 9. The appliance should be mounted on a fully supported base extending the full width and depth of the unit. The appliance may be located onornearconventional constructionmaterials. However, if installed on combustible materials, such as carpeting, vinyl tile, etc., a metal or woodbarriercoveringtheentirebottomsurface must be used. MANUFACTURED HOME REQUIREMENTS This appliance may be installed in an aftermarket permanently located, manufactured home (USA only) or mobile home, where not prohibited by local codes. Cet appareil peut etre installe dans un maisonprefabriquee (E.-U. seulement) ou mobile deja installee a demeure si les reglements locaux le permettent.
