Re: Circulating orientation + air leak during pressure test questions
Motors should not be installed facing the floor or the ceiling. The motor shaft must be installed horizontally.

Re: Boiler pressure at 40psi but relief valve rated at 30 psi not opening
Also, and this is most common, make sure you are reading the proper part of the gauge. One side of the line shows feet in h2o, and the other side is psi. You might be reading the wrong side, and actually have about 20 psi.

Re: Tiger loops with two burners.
Top of tank only 4’ above burners.
Siphon should be maintained.

Tigerloop specifically says only one burner per unit.

Tiger loops due to eventual bubble formation in overhead supply.

Re: Are mod-con high efficiency boilers false economy Vs traditional cast iron over a longer time frame?
Id look at the structure first, get the load as low as possible with reasonable upgrades
Then a heatloss calculation
Then a radiator assessment
Only then should you make a fair comparison
suppose 80% of the year you could run 129f supply? Not unheard if with over radiated homes
At least 15 years, closer to 20 on name brand
Mod cons
micro zoning can cycle a cast boiler to death, efficiency can plunge
Combustion air requirements need to be addressed also with conventional boilers. Return protection on an ODR cast boiler needs to be addressed

Re: Pressuretrol issue
I very much suspect that the problem is that the boiler is sized to handle all the units running at once. That means that if only one unit is calling, the boiler is oversized by a factor of 5 or so. You will -- no matter how hard you try -- get a very rapid pressure rise in that case. To add pain to misery, the boiler is probably oversized even for all the units running at once...
Re: Radiator cover
First I would use a flashlight and mirror to see if there are any hidden clamps. If not, break the paint seal around the edges, then pull straight out at the bottom and slide down a half inch or so.I think on that one, you have to pull the front cover UP before pulling it OUT.
Re: Radiator cover
They are all different and there are no Majic tricks. Just investigate and take your time
Re: Added Vents, Lost Heat?
B4 you use the 2x 4 start at the boiler end and figure out which way the pipes need to pitch and use a level.
Your technician who installed the vents and the new near boiler piping should have gone through the system and figured this all out
