Re: Am I blind? Not seeing the gas shut-off valve.
This is interesting. It appears that the suggested piping design for a zone system using pumps that is on page 28 in the manual was not used. in fact they piped it as I feared and this design may not yield the results that the manufacturer intended. Here is the supply piping from the oil boiler:
This is the closest I can get from the photos. Now in the new boiler piping That was not going to be a cluster of piping behind the new boiler (which in my opinion that IS a cluster of piping) and be installed in accordance with the manufacturer's I/O manual (this is the closest one to what you have) using a primary secondary layout.
You can clearly see that the as built piping is not using a primary secondary piping design here:
In fact this piping design is based on old school direct piping from the supply to the return of each zone. Also I can not see zone D piping in the as built piping. This piping design lends itself to improper hydraulic separation of the zone pumps from the internal boiler pump which may cause a problem in transferring heat from the boiler heat exchanger to the system if for some reason all three (or four) zones call at the same time. All the zone pumps are forcing all the flow of all the zones thru the boiler heat exchanger at the same time. The primary /secondary piping will create the hydraulic separation that the manufacturer requires for the best operation and longest boiler life.
If the installing contractor will not make this right, then I would contact the manufacturer's representative, the gas company that is supplying the money for the contractor, and the authority having jurisdiction and lodge a complaint that you believe that the installing contractor did not follow the IO manual and you would like them to put whatever influence they have with that contractor and make them install it properly.
I hope you followed my recommendations to withhold payment until you are satisfied that the system is operating properly. Which it is not at this time.
Re: Gravity compression tank connection
True. At least until the bladder fails. But why not just use the steel compression tank? Too simple…
Re: Reanimating Frankenstein - a gravity heat story
TRV's will regulate the room temperature and the outdoor reset will regulate the temperature of the water needed to heat the building at that time. Adjust the outdoor control to heat the coldest flat and the TRV's will slow the flow to the other floors or rooms to prevent overheating .. The old thermostat serves no purpose other than another switch .

This may or may not be his area of expertise. If not he may know someone who can help.
Are the pool chemicals part of the issue? You do have a heat exchanger between the boiler and the pool?
Re: Vesta VRC repeated purge
Sounds like it could be the air proving switch for the inducer. Check tubing for blockage or condensate not draining etc
Or could be ignitor/flame sensor.
Not familiar with that boiler
Re: Steam Boiler Pressure & Some Of My Adventures
If that were mine I'd use a standard gauge and pigtail. You can clean a standard pigtail, but not an internal syphon.
Re: Reanimating Frankenstein - a gravity heat story
TRV work well with gravity system, perfect way to balance the heat in a constantly circulating system. No worries about deadheading the pump either.

Re: Am I blind? Not seeing the gas shut-off valve.
then that is the shutoff for the boiler.
I think you said it was 3 story. if that is the case the pressure needs to be around 18 psig to fill the system to the top

Re: Gravity compression tank connection
A B&G Airtrol fitting will prevent that. This is my preferred setup, since it eliminates the diaphragm or bladder which eventually fails, necessitating a completely new tank.
Re: Ever use an off brand press tool?
I’d think the jaws and tools would need to be designed as calibrated pair from factory. I know from experience jaws do go bad and have learned to replace if you get more than a couple leakers on clean jaws. I’d be concerned you would risk same issue with mismatched system.
