Have to remove the glass cover, logs, grate and burner. The pilot assy has RTV silicone on around the whole for the tubes/wires. Make sure you have some high heat red or copper RTV silicon sealant before hand. Get it at a local auto parts store.
Turn off the gas, remove the front control panel...like the louvers....lifts off tan gs. NOTE: notice the wire colors n locations...take pic with phone. Disconnect the 2-tubes, 3 wires, 2 screws holding the assy in in the firebox. NOTE: the holes which items feed through into the firebox (pic). Since you are replacing them, just use wire cutters n cut the ends off...easier to pullout. Then you can remove the old RTV sealant. NOTE: Careful bending the tubes...they are fragile....if you crimp them, they are no good. Install the new assy feeding the tubes and wire through the same holes. Screw the assy in place. Now you see why you have the burner removed.....so you can reapply RTV sealant. NOTE: If you have some nitrile disposable gloves they are nice for this....so you do not have sealant all over your hands....hard to get off. Connect everything back together as your pics show. Test the unit before replacing the logs or grate. Then finish reassembly.

1. Turn off gas to unit,

5. I wore mechanic gloves and long sleeve shirt when remov ing and installing the assembly.
6. Also I used high temp caulk to replace the caulk the I removed, available at the Auto Parts store
(wear nitrite gloves when reapplying) let dry for 24hrs
7. Reinstalled, made all connections, tested gas line with soapy water for leaks.
8. Fired unit up and is working fine.
Note: On my unit their are numerous sheet metal screws with sharp points that will cut you, that is why the gloves and shirt.
