I don't know about the RT recommends priming after ever use. It's contrary to their statement here. The ignition cycle primes it for ignition.
"Place a small handful of pellets in the Fire Pot. Do not overfill. Do not obstruct the air-holes, as fire needs oxygen. The purpose of this is to "prime" the Fire Pot. When a grill is brand new the auger tube is devoid of pellets (fuel). This step will allow the grill to start a fire as the auger pushes pellets toward it. You will not have to repeat this step UNLESS you run the grill completely out of pellets."
