There were three screws to remove the igniter assy out of the way, then I used a 1/4" three foot long copper tube attached to a shop blow gun and simply fed a few inches of it up the flue and blew it out. That beat the hell out of removing the fridge into the trailer kitchen and manually pulling the baffle up and out to clean.
