You need to replace the burner orifices and change the gas presssure regulator, then adjust the air shutters on the burners to get a bright blue flame with minimum yellow tipping. The orifice hole size differs for the surface burners and the oven/broiler burners. One of the part numbers is 255887, and the price is $9.50. You'll need to ask which one this is, as the other(s) are'nt shown at www.repairclinic.com.
