Push and pull the brush up and down a few hundred times to remove the rust. ;)

What do you do about the spiral baffle??????????????? Doug

Once the roof vent is off, lift up the spiral baffle and clean it off.

A LOT of work when you can just blow it out in 5 minutes. Lets see, you have to remove the cover. Then you have to remove the screen cover(about 30 screws) and remove it. JUST TO REMOVE A SPIRAL BAFFLE??????????????. Then you have to reinstall the screen cover and seal it to the roof and then reinstall the top cover. AND this is hoping that they centered the refer and roof vent in the cabinet and you can easily get to the Spiral baffle if it is not aligned with the rectangular roof cut out. Doug

When my burner gets covered with rust, I use a small hammer and tap on the flue to remove the loose rust that hasn't fell on the burner yet. Then I blow every thing off and all is well for a year or two.

This may not be an option for you, and others may disagree, but during the 10 years I owned my motorhome I left it plugged in nearly all the time and left the fridge on. Keeping everything warm eliminates condensation and therefore rust. In 10 years I never had a single fridge issue. Maybe I could have bought a fridge or two for the cost of the power it used, but I never worried about it.

Ok bad terminology
Rust falls into burner holes from above
Causes yellow flame and throws code
Blowing compressed air up flue would have to be done with burner/orifice assembly removed
I'm trying that next time I need to dump the rust particles out of it when it starts to burn yellow. I could not blow the rust particles out of the burner while still installed tried that. Had to remove and rinse out in alcohol.

Blowing compressed air into and up the flue does not mean you have to remove the burner orifice assbly. I use something similiar to this. I modified it by bending the end tip to about 45 to 60 degrees. More than enough to slide in and get up the flue tube. Doug

I do something similar by bending a plastic tube up the flue and using compressed air once a year. I keep the plastic tube inside the refer compartment and whenever flakes fall down on the burner tube I just blow it off using the plastic tube like a straw.
