Re: Outdoor reset
I just called vesta tech support and the guy told me they have them in stock and can ship them out overnight shipping so you might try calling them again! They also told me you could use a 3rd party one for what its worth i didnt ask for that part number i just told them I was trying to help someone locate a sensor for a VRC combi

Re: I'm getting solar panels. I'll let you know how it goes in this discussion thread.
Update: The fire inspection passed (that one was basically to verify necessary clear areas on the roof). Then the solar contractor applied for the final inspection and Net Meter from PSE&G (our power company).
Today I got notification that PSE&G processed that application and ordered the net meter. They will do a final inspection and swap the meter within 25 days if everything looks good.

Not a condensing boiler.
Look at the vent pipe. A condensing boiler would use a plastic vent pipe because all the flue gas condensation would rot the galvanized vent connector away in a year. According to the manual this is a better way to do the near boiler piping if you want less problems with air in the system.
Assuming that you are connecting to standard Baseboard heating units with 3/4" copper tube. The circulator on the return indicates the installer didn't read the manual and followed the directions his father who taught him to do it that way.

@mattmia2 " What is this tube, where does it go? "
This tube ? Maybe the radiator supply.
Multiple pressure controls the lower two looks like Vaporstat size diaphragm diameter.

Re: Steam device to be identified
@Steamhead It appears to vent the air out, it has to go through a bit of water at least the height of the boiler water, Figure 205. It makes it harder for the air to get back in resulting in a vacuum for faster steam propagation with the next cycle.

Re: Steam device to be identified
The regulating valve isn't that complicated. Basically, in a 2-pipe steam system there has to be a way to keep steam out of the dry (overhead) returns, which are only sized to carry returning condensate (water) and air. There are several methods, steam traps being one, but in a Tudor system the radiator valve contains a restriction, or orifice, that will only let a certain amount of steam enter the radiator at a certain design pressure. So, if the steam pressure is kept to that certain point, there will not be enough steam entering the radiator to fill it completely and enter the dry return. In the valves described, the installer sets the restrictor, and after that the owner cannot open the valve any further.
One of the nice things about this method is its lack of moving parts that will need servicing.
So, how does the air get out of this system? Basic principle is, steam will not go where there is air. In figure 205, a pipe leaves the "safety valve" and exhausts the air outside. Is it possible this system once had such an air pipe?
A couple other things to check:
1- blocked return line between the "safety valve" and the boiler, and
2- boiler pressure getting too high, which can force the returning water out the vent.
Re: Steam device to be identified
I’m with Steamhead: boiler-return trap. Do you have photos of a radiator? Close-up of the supply and return sides would be helpful. And welcome!

The fuel pump cover bolts takes a 5/32 Allen head. And no smoke or anything odd that you could tell? Awesome. Looks like you got it handled.

Those are the cleanout ports for the heat exchanger (HX). The proper cleaning tool is a 1-1/2 diameter horse hair brush with a 36" to 42" handle in order to wrap around the curve of the HX then you vacuum what falls to the bottom with a flexible 1.12" soot snorkel. Cleanout Brush.
As far as the fuel pump is concerned you will need a replacement gasket on hand to service the strainer, or you can just purchase a replacement strainer that comes with a gasket. Suntec 3779901 cover gasket or Suntec strainer S160-14
Or you can get the same parts with the RW Beckett name on them for more money. Beckett S160-14
