it should have 2 or 3 screws at the bottom of the front panel. depending on the model you may also need to remove some along the top of the back mounting bracket.DO NOT REMOVE THE SCREWS AT THE TOP ON THE SIDES UNTIL ALL BRICKS ARE REMOVED.
this will allow the front panel lift up a little and come away.
this give access to another panel with maybe 8 screws around the edge. 5 or 6 along the top and more at the sides.this panel then lifts up slightly and comes away.
now you have access to the front row of blocks. remove them to get access to the elements. to remove the back row of blocks you need to loosen either: the screw, in the middle of the connector, holding the element in place. this only lets it move a little so be careful.
or:the top screws, of the connector, holding the element. this lets you remove the element. screws can be tight so hold the connector, its ceramic so breaks easily.
have fun!....and mind the sharp edges of the panels
