Dont know if this is standard on all modern stoves or not. I have the PE Super 27. It has the removable piece of angle iron ( with holes in it ) along the front of the stove. (I think its the manifold) It eventually gets alot of ashes built up under there. Was wondering if the hole ever needs cleaned out and if it does, how would one go about doing that. Not having any prob's, just curious for future reference...Thanky much
