The igniter is located directly below the hopper in the centre of the cooker, and to access the igniter, the convection blower must be removed from its bracket.
On freestanding cookers, the convection blower is located on the right side of the cooker, facing the front.
On built-in cookers, the convection blower is located on the left side.
The positions of the blower mounting screws are also slightly different: one is in a vertical position and the other is in a horizontal position.
