There should be a couple of screws holding the pilot bracket to the bottom of the stove. Use a 1/4' drive - magnetic is best - to remove the screws. Gently lift the entire pilot bracket assembly upwards far enough to access the retainer nut for the t-pile. You may have some difficulty removing the t-pile from the plate it sits in, because they sometimes distort. I can't emphasize enough that you have to be gentle. The pilot tube is thin-walled & can fracture easily. If you must, loosen the pilot tube from the underside, as well as the thermocouple. Disconnect the the electrical connections of the t-pile at the valve terminal block. Once you get the t-pile out of the bracket, pull the wires up through the hole in the bottom of the stove. Install the t-pile & feed the wires back down thru the hole & gently reposition the bracket assembly in position, reconnecting the pilot tube & the t-couple if you removed them. Apply a goob of RTV to the hole where you fed the wiring thru. Reattach the screws - this is where the magnetic tip is REALLY handy - retaining the bracket to the stove & reconnect the wires to the terminal block. Light er up & see if she works.
