Re: DIY questions tuning up my furnace
You need a combustion analyzer and to know how to use it to change the nozzle as well as how to adjust the burner. It isn't a DIY project.
Re: Manual J Heat Loss Calculation
Don't sweat it. Make good general estimates of al that sort of thing — no need to get carried away. Remember too that this Manual J is for the building code folks — since this is steam, you are going to size the boiler to the radiation anyway, not the building heat loss.
Re: Main vent making loud noises
I would say that is not normal, my Big Mouth is petty quiet last I checked it. Maybe the 'O' ring needs replacing.
Re: Main vent making loud noises
I'm gonna guess it's not the bigmouth, but the main dragging itself across a support or hanger somewhere as the main expands, or contracts, find the binding spot and slip in a piece of milk carton plastic to allow for a slipp
Re: Tekmar 360 Control- Assistance Needed
I usea small stainless hose clamp. Yes insulation over it. A chunk of fiberglass even if you don't have pipe insulation.
The tekmar sensors have a small dish groove in the sensor so they fasten to pipe well.
You can change and adapt if the system doesn't do exactly what you want the first attempt.
Write down the settings as you make them to keep track of what change makes what difference.
I imagine many controls go in with factor default settings, no one comes back to fine tune it to the exact application. So for the homeowner to learn settings and adjustments really maximizes what the control can do for you.
I just bought an EV truck, it may take the rest of my life to figure out all the settings and options, which they update on a weekly basis!

Re: 24 Volt transformer blowing
Can you trace visually along the problem wire and find where it is damaged and shorting?
Re: Hydronic Baseboard Gap
Rooms with a lot of glass tend to feel "cold" even though the ambient is warm. Your body heat is being pulled to the cold glass. AKA the "cold 70 effect"
Use an accurate thermometer to adjust the wall thermostat reading. There is a differential in the thermostat 1.5- 2° that may be adjustable also. Pull out the manual on your thermostst.
The wall thermostat is on an inside wall?
This smiling gentleman explains cold 70 the concept well.

Re: Tekmar 360 Control- Assistance Needed
What I find that helps with tekmar sometimes is to look at their application guide
Re: Explain This Relay!
My guess is similar to @mattmia2
I would guess they went to 1 stat for whatever reason so the stat would open both valves and pull in the relay coil. The relay contacts would act as the end switch and fire the boiler. Not exactly right but I guess it works.
The boiler and circ shouldn't run until the valves open but with no valve end switches(s) it can't be done
