Re: Newly Commissioned Lochinvar - Blown Gas Valve
As silly as it sounds, I have had electrical problems that went away after I unplugged and re-plugged the connectors on the boiler circuit boards.
The surge protectors that I have replaced have not been the circuit breaker types. I have used whole house surge protector with surge capacitor that sets in the panel box or mounts on the bottom of a surface mounted service entrance panel. You need 2 breaker spaces for them to connect to. Might try:

Update: Mid-January 2026.
Still running as it should after doing what I did in the post above. No issues.
Re: Loud hissing from nearly all radiators during this cold spell
Trying to make up 4 degrees in Zero degree weather is something you should avoid doing .. you want to maintain your temperature, not increasing it 4 degrees daily and letting the home cool down 4 degrees at night.. especially at Zero degrees

Re: That Pesky O₂ Molecule – How Oxygen Finds Its Way Back Into a Steam Boiler
You are in a difficult situation with that removed radiation.
But you are exacerbating it with that 5 degree setback at night. I recommend stop doing that and see if the downstairs is able to stay comfortable.
If the upstairs gets too hot for your comfort at night, try covering one or more radiators with blankets until you are comfortable, but keep in mind doing so is similar to removing radiation and may make your system cycle more.
Cycling more isn't a big deal for gas, but could be more problematic for oil.

@hot_rod and @RayWohlfarth know a lot more about this, you almost have to treat it like process steam.
Re: Steam Heat System Intermittent Firing
No, the controller has no built in long term time delay. So… my thought is something got fired, and the question what. If this is a "smart" thermostat, which it sounds as though it is (programmable) the first thing I'd try is to run the boiler without it. That is, locate the T-T terminals on the controller and jump between them. The boiler should fire up normally. If it does, go to the thermostat itself and turn it up. Again, the boiler should fire up normally. If it doesn't, take the thermostat off the wall and locate the signal terminals — usually red and white — and jump between them. The boiler should fire. If it does, then the thermostat is wonky.
If, on the first test above, the boiler doesn't fire, it may be a problem in the burner controller.
Re: Loud hissing from nearly all radiators during this cold spell
you would need a low pressure gauge to see any meaningful pressure readings.
I guess i would ask are the radiators that are making noise steam hot at the vent location when they are making noise?
Re: Loud hissing from nearly all radiators during this cold spell
Try to clock the meter or have someone measure the gas pressure. Boiler might be over fired
Re: Loud hissing from nearly all radiators during this cold spell
Never assume that the gas regulator, in the gas control, is actually properly set.
Re: Loud hissing from nearly all radiators during this cold spell
You would know what is happening if you put a 0 to 3 psi low pressure gauge in. Then, if the pressuretrol is malfunctioning it would be immediately apparent and you wouldn't be wondering.
