Usually 4-8 hours on a pressure test. Charge it and shut the valve, if the pressure doesn't drop in 8 hours you're good.

Axeman recommends aluminum paint, reduces heat radiation is the idea I believe.

Do not, under any circumstances, remove the blower wheel from the shaft. It is a balanced assembly. Note the position of any other items on the shaft and make sure they get replaced exactly as they were.

Right, I saw something about that on another thread somewhere, thanks for the reinforcement. So the way it appears to me, the fan and shaft don't touch anything once thru the fan housing? There is no bearings past that wall, instead it's all suspended from the box out front that the shaft runs thru?

No bearing would last in that heat. The 260M actually has a finned disc on the shaft behind the big plate. It's sole function is to keep the heat from travelling down the shaft to the bushing box. Not sure if it is on the 130M.

I spent a few hours on the AA today...

Pulled out the ash grate.

Bottom of the burn chamber.

Two of the four ash grate rollers are frozen. The fly ash cyclone was clogged with ash, I cleaned it out.

Here's the cyclonic flue gas heat exchanger. Yeah she looks rough but nothin some spit and shine can't fix!

I broke the two bolts hold this bracket to the fan housing. I'll need to grind off the nuts and weld on new ones. The bolts were pretty weak, it didn't take much to snap them off.

Question. What is the best way to get this fan plate out from between that box and the fan blades?

Remeber, that bracket is just for shipping. Don't leave it on there after you install the boiler.

I would pull the fan off. Make sure you make alignment marks on the fan and the shaft before you remove it.

I tried that. Do these two bolts thread into the blocks that are clamped around the shaft? I was able to remove the nuts but couldn't get any further.

The AA doesn’t have any of the tubes inside the cyclone?

No to both...Bracket for transport only...fan needs to be free and only supported off rubber foot on floor and the horizontal flat iron brace half way up. Fan pretty much "floats" through the plate hole.

No, AA has ever had those AHS/Eshland "gizzys" in the center tube.

That sure looks like a clamp. Maybe the blocks are threaded too. I don't know you are ahead of me, I haven't even pulled the fan plate on mine.

I saw this fan removal topic discussed before, and I am pretty sure it was McGiever's fan that needed to be removed. I did a quick search for the thread and couldn't find it.
