Cleaning the 'flue' on my Dometic standard fridge

Anyone who has experiance with cleaning the fluu on a fridge they burn alot of propane in .... can you please explain the process involved i.e....:

a) Where is the "fluu" and does it vent @ the roof on the coach?
b) Does the "fluu" need to be removed to properly clean?
c) Is the "fluu" kind of like a chimny or exhaust vent?

If you could step by step describe the process involved I would really appreciate it thank you in advance!

The refer Flue can be accessed from the roof,that is if you have a roof vent and not a side vent in the case of a refer mounted in a slide.

It is necessary to remove the roof vent cap(4 Screws) & lift off the cap.
You can look down through the roof vent screen to see the flue (3/4"round pipe).It will be necessary to cut part of the vent screen away to gain access to the spiral baffle inside of the flue.Pull the baffle up and out of the flue.

You can obtain a round 3/4" wire brush from any oil burner supply store to run up and down in the flue.

If your upper vent is side mounted then it will be necessary to remove the refer from its enclosure.

Be aware there is a baffle of sorts INSIDE the flue, a corkscrew looking device used to control heat dispersal for most efficient operation - if that gets dislodged or damaged, you'll end up with far worse problems than soot in your flue...

Fact is, unless your propane burner flame is seriously misadjusted, the flue probably won't need cleaning - ones I have seen after over 20 years use sure didn't need cleaning...

There is both a propane chimney for exhaust gasses and a vent space for heat from the cooling unit. Both need to be free of obstructions, but that is seldom an issue. If you get rust or bug nests in the propane chimney, it needs cleaning, but often that can be done from the bottom with a vacuum. I've been RVing for 15+ years and never seen one that needed to be cleaned from top to bottom like a chimney sweep would do.
