Removed LP Orifice and LP Gas limiter.
Orifice was easy, however the gas limiter was the tricky one because I had no instructions to what went where. I could not find anything online as to how to convert from LP to Natural Gas, but you could find several things as to how to convert from Natural to LP.
I ended up finding the Dryer schematic on line for the Whirlpool Duet natural gas dryer and was able to figure out what sequence the Spring, regulator and limiter went in. The order I just listed is how I installed them.
