polgara, you should be able to follow the igniter leads from the back all the way to the igniter (sorta dead center of the unit, a few inches up from the bottom). Its screwed in there, so a bit of "lefty loosey" turning and hopefully it just falls out into your hand. Occasionally the threads are stripped and what seems very simple turns into some banging, swearing, a lil more banging and a good pull. The blower is something else all together, you may want to start a different thread for that.
