Luke S Newport Beach , CA September 13, 2016 Appliance: General Electric Gas Range ZGU385LSM1SS Ge stovetop configured for lp in nat gas house Previous owners did kitchen renovation years ago and nobody noticed that delivered stove top was the Propane model (and never converted to nat gas). Flame was weak (took long to cook) and sometimes went out. Boiling water could take a long time. After shutting off gas and unplugging stove, I followed directions to change setting on regulator and replace LP-sized orifices with nat gas-sized orifices.
