@HVACNUT which is why he should take that valve ot and install a check valve.
Re: Main Vent Location
Then if you think your short of venting you can put larger vents on any radiators that are near the end of the main.
But the best alternative to a main vent is to take the radiator valve off one of the rads and install a tee with a vent on the inlet to the radiator. Keep the radiator vent.
This is called a riser vent or a master vent.
Re: Commercial Building help please
You will have 3 controls, one that sets the threshold between low and high fire, one that turns the burner off altogether, and a 3rd with a setpoint higher than the operating controls that is manual rest so if the operating control fails and trips manual reset control, you know that you have to fix the operating control. The manual rest control won't trip unless something has gone wrong. Ideally the manual reset control would be on a separate tapping and water seal.

Re: Pressuretrols and Gauges
Usually, manual reset pressure control is installed on commercial jobs. In MA where I am they are required over 200,000btu.
If in doubt put it on the new boiler. It should be on its own pigtail not doubled up like on the old boiler.
No pressure on the gauge is a good thing not a bad thing. Put a LP gauge on if you want. You have to keep the 0-30 gauge and I would put a petcock on the LP gauge only. Keep it off when not checking pressure.
Re: Bosch Combi Boiler ZBR 28-3 Issue
It appears that you’re leaking flue gasses into the cabinet and recirculating them back into the burner.
That’s a dangerous situation and should be corrected immediately.
A combustion analysis should also be done.

Re: How to keep an electronic record of when boiler fired
I am monitoring every run my boiler makes because I have a new system. I put a security camera, one that can do continuous record in 5 minute clips and record sound, in front of the boiler's LED panel. Once a day I download all the videos and find the on times and off times. It is laborious but I sort of like doing it. I put the data in a spread sheet.It is so interesting to me that, based on this thread, it seems LOTS of people have the same question -- we want to know exactly when our boiler is firing! But how is it no stock solutions exist for this? It just seems that the boiler manufacturers should have an easy add-on for tracking and analytics.
I don't think it would work for most people because the thumbnail of every video has to be checked to see when the temperature is higher than the thumbnail of the previous video, and then play that video to get the date stamp time when the boiler turned on and then off from the burning gas sound. A bit laborious.
Re: Can’t figure out the banging noise in the radiator
There is almost certainly no point in taking out and cleaning the radiator. This is a pipe pitch problem. Condensate is pooling somewhere. Get rid of the pool and you will get rid of the hammer.
On the plus side, it looks like whoever installed that boiler actually read the instructions and piped it properly.
