Re: Am I blind? Not seeing the gas shut-off valve.
as far as i can tell there is no space inside for a field installed manual valve. It looks like there is factory installed tubing from the gas inlet on the bottom to the automatic gas valve.
that is likely boilerplate they bought from someone that has been the same for 40 years and is for conventional boilers with a manual knob on the automatic gas valve.

Re: Push nipple radiator problem
I would just snug up the draw rods and pressure test and see what happens.
Re: Am I blind? Not seeing the gas shut-off valve.
I can’t believe they didn’t install a valve at the equipment!

Re: Low water cutoff not working after cleaning pigtail
Assuming you have a number 67 low water cutoff. The black thing with the lever. The float might be stuck.
Re: Am I blind? Not seeing the gas shut-off valve.
Isn't the one in the third picture right above the boiler? That is the one to use.
Re: Am I blind? Not seeing the gas shut-off valve.
Follow this line back to the meter. If you don't see a shutoff valve, then the valve at your meter will be the shutoff. There should have been one at the boiler.
Re: Tempstar furnace no heat.
Oh, it definitely has a pilot. That’s what the 1/4” aluminum tube from the gas valve is feeding.
The spark lights the pilot, not the burners.

Re: Shutting off or lowering water temp
I have a boiler with an indirect. Even if we're away over night I turn it off and the water.
The only issue may be if it's an old boiler that's never been 'cold' it may leak.
During the heating season I'd recommend to only lower the thermostat(s) (not too low). The indirect may only call the boiler to fire once or twice for 10 minutes over the course of a day. If you have a mixing valve on your indirect, you could consider turning down the indirect's aquastat, then turning it back up when you get home. You'll have to make your own decisions about Legionnaires.
Generally when we get home from a vacation, I turn everything back on and we usually do a load or two laundry first, so I figure the indirect is back up to temp & hot water has gone thru the pipes. I also leave my boiler feed off and have a lwco.
I turn my system off for safety as I don't want to risk a disaster with water. I also never take a vacation when it's cold enough to need heat.
I don't really expect to see much of a savings lower water temperatures for a day or two. Insulate pipes, insulate building envelope for biggest savings.
