How to Clean a Rheem Oil Heater

I am new to this post. I need to clean my RHEEM oil heater and I need instructions. I purchased it a few years back. I have not had it cleaned in a while and tonight I smelled a burnt oil coming through the vents. I changed the filter and it continues to have a burnt odor. I turned it off in fear of maybe something happening?! I have never done this and I will have to do this on Sunday AM. Your suggestions will be greatly appreciated. Thank you.

Most Rheems have a flue collector box on the front to which the vent pipe attaches. You have to remove the vent pipe & take out 15-20 1/4" hex head screws to remove the box. Once you have the box off you will need a long handled brush to brush out the oval flueways. You will also need a soot vac to suck out the soot. Don't try to use a shop vac or you will likely have soot everywhere &/or destroy the shop vac. By the time you buy a soot vac, you are better off hiring a professional to do it.

What condition is the air filter in? It's been changed regularly right?
