This was helpful. Having a bit of a problem with flames jumping from the burner to the orifice area in the air-gap on my grill. About to take it apart to see what's going on. Hopefully just a partially plugged orifice or loose retaining nut, but this is instructive.
P.S. Rant coming. These grills are, in my opinion, shall we say, "junk." I may clean up my grill, make sure it's working as it should, and set it aside. I'm thinking of a Weber Q-series as a replacement along with a hose to adapt to a 20# propane tank (free-standing). The concept of the "camper grill" is good, but the execution leaves a lot to be desired.
I keep mine in a box on the floor inside my PUP. We boondock exclusively, and I've found mine rattled apart into pieces many times. The flame shield fell apart...the welds between the shield and the legs broke and I had to fix with screws. The handles rattled off...all three of them. The burner control retaining screws fell out. The burner itself literally disassembled itself in to parts.
Plus, the thing was a complete disappointment for cooking from the get-go. I love grilling, and as far as I'm concerned, this is one sorry excuse for a grill.
Since it's an expected part of the camper, I plan to restore mine and set it aside. I plan to upgrade to another type of camper in the near future, so I want this thing is good condition for the trade in. As for the new camper, if I buy from a dealer, this grill will be a "delete option." I won't ever buy another.
Here in Colorado, fire bans have become the norm. A good gas grill is no longer optional, because, during bans, even charcoal grills are not allowed. (I have a fabulous stainless steel folding charcoal grill I choose first if possible.)
I also have a propane fire pit. It works great and does not fall apart while driving down the road! So I always have at least one extra 20# propane tank "hanging around" to run the fire pit.
End of rant.
