This kit switches the front and rear burners of an Enviro G42 log fireplace from propane to natural gas by replacing the main orifices and pilot orifice insert and resetting the Nova valve's conversion screw. It is genuine Enviro part 50-3590, built for the Enviro G42 with the Nova millivolt valve (G42L configuration) and log burners only.
