Here's a video for cleaning the AHS 130 swirl chamber...

Here's an important HANDY HINT:
Buy a new gasket from AA for reassembly, they do live in a very harsh environment and degrade when disturbed or handled.

Here are some pictures and a description of what to do.
AA130

It's pretty easy and you should do this once a year. The first thing to do is get a new fan plate gasket from Axeman.
Remove the fan belt.
Remove the fan plate nuts and bolts. If they are to rusty just cut them off. They are 1/4"x20" and 2" long.
Remove the 4 nuts and bolts holding the fan bearing housing to the pedestal.
Pull the bearing box, fan plate and fan out very carefully. The pedestal is in the way but you can get it out.

When removing the bearing box watch out for the oil coming out of it. It has no seals so removing it will dump some oil. For me, it always gets my shoe and/or pant leg.

Fascinating degree of sophisticated engineering on that bearing box. And as reliable as a bucket to rocks too.

I scraped down to where slight rust colors showed. Is that enough?

Most of your answers are in this video play list.

For silver paint, I use Rust-O-Leum high heat silver.

I tried to find paint but did not know if it has to be high temp? Actually Don just gave an answer. Thanks

Remove the stove pipe off the boiler breech and you're then looking down into the cone area...you'll notice the side port into where you've already cleaned. Now a hand light shining from where you already cleaned would make it oh so obvious.

You can save yourself much work if you would remove that same stove pipe at the end of the heating season and clean and store that pipe in a warm place like up in the rafters or an attic till needed again. Also tape a plastic shopping bag over the baro and another over the exposed stove pipe end to halt all (moist) chimney air flow for the summer duration.

Cleaning behind that gasketed plate is gauged by X amount of tons burned, not by season. And having not removed the pipe attached is what got you what you have found now. Some guys will hang a light bulb or equal for the off season to keep things dry inside. :)

And never allow any cold water to run through that tankless coil either with the boiler shut down for the summer...add valves and bypass the water outside of that coil. Fly ash surfaces that are cooled below their condensing temps will rust those surfaces heavily for the whole time.

I put a light in the small area between the inner and outer circles . I shut off all other lights and looked down the hole where the chimney hooks up . Could barely see any light . So how do you clean that passage way? From the chimney area or from where I took the blower off ? I poked around with a wire and could not get it to show up in the vertical tube to the chimney...

There is a part called the "Pope's hat" that runs about half way down into the boiler at the exhaust port. That is the cyclonic separator. If that Pope's hat is installed it will be in the way of getting a wire thru that small port from the swirl chamber into the cyclonic separator. The Pope's hat would also be blocking the light you put in the swirl chamber to try and see down thru the exhaust port.

So how do I clean that passage and know if it’s clean? Can’t see in there ...
