The grill and required parts arrived while I was on a business trip so today was the day for the conversion.
The parts I used were the 3/8 x 1/4 female adapter and the camco male LPG fitting. Also some yellow LPG tape.
I removed the regulator from the Q and then separated the regulator from the gas control valve.
I then installed the new fittings onto the gas control valve. and reassembled the grill
I then connected the grill to the coach and here is what I got based on the Q's thermometer.
Valve on low - 250 - 275 degrees
Valve on medium - 325 - 350 degrees
Valve on high - 425 - 450 degrees
I allowed the control to remain in each position for 15 minutes to stabilize before moving to the next position.
So far I am happy with the setup. Tomorrow afternoon dinner will be cooked in the driveway and we will do a test cook of grilled chicken and zucs.
