This was remove and replace of burner valve on a rangetop stove. Removed front pannel of stove. Removed lower panel support. Removed ignition/spark material/peice (slides right off). Unscrewed valve form underneath through access hole, and unscrewed gas connection on top. Removed and eplaced with new valve and reassembled everything in order. Fairly straight forward.
change over from Natural Gas to LP and install cooktop from Electric to gas
removed old electric cooktop and install gas line and gas cooktop and change from natural gas to LP remove and replace orifice with new ones from kit, my cooktop called for 2 black orifices in the two small burners but did not come in the parts kit that I orded so I used 2 red orifices and it seems to work just fine.
