YEP...Brand NEW Version (Standard 6 gal combo and '9 gal' combo XT model)
Dometic moved the combustion/exhaust 'U' tube to center area (stacked one above other) so that they could install electric element in front (vs backside like previous models)
Now access to all components is available via outside compartment
Along with that change...burner/orifice assembly now no longer has 'air shutter'
Yellow/lazy flame....dirty orifice/burner tube
Spiders LOVE propane and will build a web quick as they can.
Web WILL disrupt the narrow air/fuel ratio and cause yellow flame (gas flow MUST be at spec in order to 'pull' sufficient air in via venturi)
Air Pressure will not disturb spider webs....
Clean using small bottle brush for burner tube
Soak orifice in alcohol then blow it dry...just use your mouth to blow NOT high pressure air or poke anything thru it---damage the metered hole and you will need a new orifice
