9 WARNING
Risk of fire
Grease deposits in the grease filter may catch
fire. The specified safety distances must be
observed in order to prevent an accumulation of
heat. Observe the specifications for your
cooking appliance. If gas and electric cooktops
are operated together, the largest specified
distance applies.
Only one side of the appliance may be installed
directly next to a high-sided unit or a wall. The
distance between the appliance and wall or
high-sided unit must be at least 2" (50 mm).
The minimum distance between the supporting
surface for the cooking equipment on the hob and the
lowest part of the range hood must be not less than
30 " (760 mm) from electric cookers and 30 "

If the instructions for installation for the gas hob
specify a greater distance, this must be adhered to.
