Burner Tube Air Adjustments on new Dometic Appliances?

Just picked up our new Odyssey 24B from the dealer last weekend. Took it out the one of our favorite campgrounds on the way home. Did a pretty through walkthrough before we took delivery. Made sure water heater and refrigerator started in gas and electric, etc. Got to the CG and started water heater. After a few minutes it stated popping, flame backing up down the burner tube and large yellow flame. To much air, ok throttle down the adjustment sleeve to reduce air in the mixture. But wait, no adjustment sleeve. Checked the owner’s manual, nothing regarding any air mix control for the flame. Model is Dometic WH-6GEA. Already had some soot build up above the vent on the door. Are the any adjustments to control the air gas mixture I am missing? Just noticed also no air adjustments on the refrigerator burner tube as well.

    Low gas pressure, something is wrong with your propane regulator or your tanks need filled.

    Refrigerator has the same problem as the water heater. Flame backs up into burner tube. I have video of both, but don't think I can post video.

    The range burners appear normal and don't seem to fluctuate when water heater or refrigerator burners start. Also had a problem with the furnace at delivery, bad internal vibration. Turned out to be a problem with the metal case. The propane supply associated with the furnace appeared to work fine.

    In my experience RV manufacturers install regulators without bothering to set them. A manometer is a good tool to own.

    They come preset. I have NEVER had to adjust a replacement LP regulator in 41 years as an RV Tech. My rule of thumb is, IF you have to adjust more than 1 inch of WC, then replace the regulator. It is not up to the job. Doug
