. Enter the full model number from the oven rim inside the drawer. The installation guide will walk you through the conversion. However, it is recommended that a qualified technician (for LP, if going to LP) do the conversion. Most LP companies will have someone who can perform the conversion. The conversion kit should have come with the documentation for the range.
I've found one model of Super Capacity 465 with the model number SF325PEEQ0. The documentation is here: http://shared.whirlpoolcorp.com/product_literature/search_results.jsp?form_state=literatureSearch&context=&siteCd=WHRCOM&form_state=literatureSearch&searchTerm=SF325PEEQ0
The steps: Make sure the power cord is disconnected, the gas supply is turned off and the grates and burner bases are removed from the top burners. Open the broiler door and locate the regulator, remove the cap from the regulator and turn it over so that LP is visible. Reinstall the cap. Do not remove the regulator. Move the range out from the countertop (about 4") if it is in place. Slide a putty knife carefully between the cooktop and the oven compartment to locate one of the clips on the side 2 3/8" back from the front of the range. While gently lifting up on the cooktop surface, push in on the clip. Repeat on the other side. Prop up the cooktop and remove the Venturi plates. Then remove one orifice at a time from the cooktop, use a 3/8" combination wrench. Replace with the same colored orifice from the kit. Lower the cooktop and reinstall all of the burner bases and other parts. In the oven, use a 1/2" combination wrench to tighten the orifice hood down to the pin (2 to 2 1/2 turns). Do not overtighten. Finish installing the range except for sliding it into the final position and then check the burners. You may need to adjust the air shutter for each burner. With the burners off, remove the knobs. Open the oven door and remove three screws from the manifold panel. Pull the panel down and away from the range. With a small screwdriver, adjust the air shutters for each burner (clockwise to let in more air, counterclockwise to reduce the air). Replace the manifold and then the control knobs and check the burners. Start the oven heating and check the burner for it. There is another air shutter next to the regulator; adjust if needed.
I hope this helps.
