Re: Oil smell after Tiger Loop installation?
I also a have a tiger loop that will sometimes have a faint smell when it vents. Look at the fuel level in the unit when it running. If you see bubbles in the fuel, then the unit should vent. The unit I believe only vents when burner is on as the fuel circulates through the pump.

Re: Best Material to Use for Drainpipes in Residential Homes.
that is leaking because the steel pipe rotted out. you could probably just replace the steel to the cast iron with pvc or copper.
the steel pipe gets rough on the inside as it rusts and clogs easily. i rarely see clogs in the trap, it is usually further in the laterals from the wall/floor to the stack or under the floor or in popup or tub drain assemblies.

The cast iron is fine. Lose the galvanized going into it and replace that with copper.
Galvanized drains are the worst IMO.
Re: Correct system, plumbing errors
Can't really see the piping — too close — so I'll not comment on that (although I do wonder if there is any header at all…)..
Keep the vapourstat, whatever else you do. That's the most reliable pressure control you could possibly have.
Now. Did anyone tell you why the boiler shouldn't be on the floor? There are basically two reasons. First, in at least some jurisdictions code requires boilers or any gas fired appliance to be raised for protection. That's one thing. Another is that the water line of the boiler is, in some installations, important relative to the rest of the piping to get reliable quiet operation. Can't tell.

Need a load calculation to see if the equipment can do the job before anything is done
Re: Correct system, plumbing errors
And who is telling you you have these issues?? Need pictures from 8-10 feet away
Re: Confused by basement runs in school 2 pipe system
There is a pipe coming up near the floor drain that may have been the wet return for the basement system.
My best guess is that when this boiler was changed a few years ago the vacuum pump was installed. There may have been no pumps at all before that.
If this was the case, it is surprising that the leaking UG wet return was addressed as it is outside the boiler and often neglected at a change out.
The school I mentioned, that this reminds me of, did locate their blueprints from the 1950's. Somewhere in your building there may be a copy of prints, hopefully no one pitched them away. Schools seldom throw anything away. One school I work on has a "Print Vault" mounted in a hollow wall. Just a 4" chrome plated cap showing, the tube is at least 36" long.
Prints might show where end of main (EOM) F&T's are located, probably above a ceiling. May have drawings of the vacuum system, if original to the building.
Where is this school located?? You (they) need someone fluent in vacuum systems.
Only a few here might be familiar with the vacuum pumps and I am not one of them.
Your short cycles might have something to do with the hi/low control. It reaches a certain pressure and should switch over to low fire but something not connected and it shuts down. The burner control panel may have a manual switch for low/high fire.

Re: Axeman-Anderson oil fired boiler vs. Burnham oil fired
What town do you live in? I'm in CT and will be going to providence tomorrow afternoon for a social event. Maybe I can stop by and take a look. Like everyone has said, you don't need a new boiler or more than likely a new burner. For some reason your cad cell is not seeing a good flame. could be the flame, the cad cell, the burner could just be dirty…
Your dealing with a company that doesn't train their techs properly and the techs are afraid to ask for help.
I sent you a PM,

Re: Steam-one boiler or two, and, Atmospheric vs Gun
The coal guy (first guy) may have made the best guess on sizing the equipment, after the installation, the coal shoveler would have been the modulating control. And often the women of the house.
The oil conversion guy then never wanted the woman to call him or send a sternly worded postcard to his office, so oversize the GPH nozzle.
The gas guy was more cautious and steps up a size.
Years later as all the vents are plugged or traps passing steam, the boiler gets changed and "You need a larger one", trying to correct the problems that are not in the boiler room.
