I know I've seen a modification to a gas smoker where a pilot light, thermostat and gas valve were added to better control the temperature. Seems like a LP gas water heater or LP gas oven valve, thermostat, thermocouple and pilot light was added. It's a hassle trying to control the temperature in my 40" Masterbuilt Smoker. Anyone have a parts list and information on how to do this mod?? Thanks and Happy Smoking! Todd.
