I saw where another member needed to know how to access the gas assembly for LP conversion. On mine, it was difficult to figure out since there is no access panel. You have to take the top panel off (two screws in the back). Then remove the four screws on the plastic top front control panel, lean outward and bump in the center to release the fixed clips. Then you can remove the door (two screws) and the door keeper (two screws) the oposing side door screws (two) and the two screws at the bottom inside door circle. at this point there are as I recall, four screws at the top that you can get to after the control panel has been moved aside. After removing all these you can lift the front panel up and off. Take care with the assembly, not to break the igniter. You can first remove the screw in the rear panel to release the gas pipe, then remove screws to allow removal of the gas assembly to give access to change the conversion orfice and regulator pin parts. This was by far the most difficult change out that I've seen. Once you have done it, it is much easier to put back together.
