Re: Dole Radiator Bleeder Valve?
My house (1956) also has these. They are not "automatic bleeder valves." They are simple, plain old manual bleeder valves, counterclockwise to vent, clockwise to tighten (as indicated by your second shot). In my house some took a little force with a wrench to loosen, I don't think they'd been touched for a long time, but once they unfroze, mine worked fine for me; the two baseboards which were not warming as much on my top floor hissed air for a few seconds, then water came out.
I hope you resolved your issue, but I just wanted to answer the Q for anyone else who might stumble on this in the future (this was the only reference I could find to these anywhere).

Re: Another New A2W HP
R290 (propane) is already here and is used in food service refrigeration. I know True is using it. No different from other refrigerants except it is obviously flammable but the service procedures are not much different. Evacuating and charging are basically the same. The whole charge needs to be removed and purged with nitrogen to do and refrigerant repairs or brazing could be exiting if the procedures are not followedThe only difference is those Systems are limited to 6 or 7 Oz total charge of R-290. 1 workaround is having 2 complete and independent Systems in the same cabinet.

Re: Can't get combustion right
Maybe turn the screw the other way. O2 and Co2 readings are dependent on each other o2 goes up Co2 goes down and vise versa. Your analyzer only measures 1 (probably 02) and the Co2 is calculated in the analyzer.
Re: Can't get combustion right
Is the UEI in good repair/calibration?
A guy I know keeps a Bacharach wet kit in his truck to verify his Testo if he runs into something that doesn't seem right.
Other than that, it sounds like an air leak.

Re: Oil to Gas Conversion Options
Before I make a final decision on CI+indirect, I did find a local Energy Kinetics dealer and have them coming over tomorrow. I suspect the price difference might be too much, but we'll see.

Re: Dunham steam traps
Here are the specs for the old Dunham 30 series F&T traps from page 10 of the Dunham General Products Bulletin of Low-Pressure Steam Heating Appliances, which you can find here:
Dunham General Products Bulletin of Low-Pressure Steam Heating Appliances
I don't think you'll go wrong with Mepco traps; when C. A. Dunham ceased operations, Mepco took over the manufacture of all the Dunham steam traps, so in that regard Dunham = Mepco (compare the above with the attached Mepco 30 brochure). That said, unless I'm mistaken, the smallest 30 series trap they currently make is the 30-7, which is an 1-1/2" trap, so your contractor should substitute the Mepco 44-2 (3/4") H-pattern trap instead. Don't let him sell you a 30-7 and bush it down, either. A 30-7 is way OVERSIZE and probably costs more than 4x the price of a 44-2. The 44-2, being an H-pattern trap, is also much easier to service; all of the guts come out attached to the face-plate and you just change it as an assembly, without having to touch any of the pipes.

Re: Is it really Necessary
Replacing phillips screw that they put in a place you can't get a screwdriver with allen head screws can make them easier to install and remove.

Re: Weil McLain direct vent ultra oil boiler-has to be constantly reset
That boiler is extremely sensitive about its combustion settings. It has the Beckett NX burner and if the draft and air isn't setup correctly it will rapidly fill with soot. The boiler can be setup to run without making any soot but there's a much smaller margin for error than other boilers. Definitely not my favorite thing to work on. You need a good technician with a digital combustion analyzer to make sure draft and combustion are set properly. It also seems like the burner runs better on the Hago nozzle specified in the manual rather than the Delavan nozzles I usually use everywhere.
Re: How to prevent undesired water flow to indirect HW heater
wait a minute,
what is the temp at the boiler?
you're not running OA resest, are you?
