Re: oversized water heater
Suggestion…Replace the water heater with a properly sized water heater that will accommodate the needs of the occupants.

Sure Paul. Who taught you to talk that way to people you never met?
Re: What do you use and why?
AAA still has the "Trip Kit". but you no longer go into the AAA location and just ask for it. It is all online and you can order the book to be sent to you by mail or download it and print it out on your printer. Still has the turn by turn directions and the points of interest along the way. I still like the old flip books!
Re: oversized water heater
A 40 gallon water heater is sufficient for 3 people. How old is the large commercial heater?
Can you sell the AO Smith Commercial on the internet? They are not cheep so you can get a couple of hundred for a used one if it is not too old. Remember you paid retail for the tank and the installers, You are not gong to get anywhere neat what you paid for it. You will be selling at less than wholesale cost and the buyer needs to pick it up. Not like getting a new one delivered by the supply house.
Re: Basic Radiator Questions (Noise!)
That air valve looks new, did someone install that to avoid fixing the trap?

Re: Replace B&G 100 or use Taco 007 monoflo
The branches were 1/2" but that didn't benefit it much. This setup was completely stupid. And it was CI radiation to boot. Interestingly enough, they piped the second floor in 1".

Re: Is my plumbing wrong
Do these radiators heat at all ? Which ones were you troubleshooting for no heat ?
What does this Trap look like ?
Is this Trap the one that is pictured above?
What is the height of this loop seal ?

Re: Lochinvar WB80 not lighting, many new parts already. SOLVED
In the wiring diagram I was looking at some of the wire colors seemed to not match your pictures. So I looked at some older manual versions. Interestingly the jumper circled in Red and then in the Red box on the wiring diagram is in the circuit that supplies power to the Gas Valve, it was a Manual Reset High Limit in another version. And you were just moving things around up there, I would inspect that jumper closely and maybe take a voltage measurement at and just past that part of the circuit.
Also it appears the circuit common is bonded to chassis ground (Green boxes).

Re: Lochinvar WB80 not lighting, many new parts already. SOLVED
109A_5 - Thank you for the additional info, I'll need to spend some time reading.
First an update. Last night (Tuesday) after I had got those disappointing numbers I spent some time poking around the cabinet trying to see what else it could be. The only wires I hadn't yet disconnected and redid were these to the top of the heat exchanger for the flue temp, and the two inlet/outlet temp sensors. Unplugged - replugged, wiggle the wires and hit Reset.
It fired up!
I let it run for a couple hours to heat the DHW and then watched it switch to SH. We've been using some portable space heaters to keep warm and outside temps have moderated so after it reached "Standby" and shut itself off I turned off the power. It was late at night/bedtime, I didn't want to take the time to run through the setup on the new control board (time/date/temp set-points,etc.) and wasn't sure what parameters might be pre-loaded on the board. Could it over-heat?
When I went to fire it up again today it failed. "No Flame Ign" Unplugged the sensors again, tried cleaning with the electric contact cleaner, wiggle wires, hit Reset. Fired up. OK good, but while I went to my laptop for the service manual it shut down. No go since.
All those wires look perfect, the connectors are clean, connection at board are good. Was it just a coincidence it fired up?
Like I said I'll study the info above. Again the board is new, the secondary board looks fine (I had already checked that a while ago) wires are all solid, connections are tight.
One thing I would note, during those couple times when it did fire up I heard a sort of fluttering sound coming from the Air Pressure Switch during ignition. Have never heard that sound during all failed ignition attempts. The puck (PRS20015) has a 2.50 wc (IIRC), I have no way to check that. All I did was gently suck on it to check if the contact closed. If I simply pulled the tube from the intake off the puck the unit threw a "APS Open" code. Any chance it could be sticking or something? The fact that it's not making any noise during failed ignition attempts seems significant?
Thank you very much for suggestions and help!
Re: Estimated life expectancy?
When we moved in it had already been redone as a preheat loop going into the electric water heater. It probably saved some electricity in winter months but not worth the extra effort.
