Re: Old Broken Solenoid Valve
This may work, but upgrading to a more modern gas valve is probably the safer option.

Re: Old Broken Solenoid Valve
What is the Make, Model number and Serial number of this unit. You will need a combination gas valve and perhaps also a 24 volt transformer. How about a picture of the pilot assembly? It looks like a complete recontrol kit. I am not sure how much you want to spend for parts plus labor. It may be better to think about applying what all that would cost plus labor and invest in a new system. If you have more questions call me at 401-437-0557 ask for Tim.
Re: Old Broken Solenoid Valve
McMaster Carr and Supply House.com both have a wide selection of these. You going to need to know voltage (probably 24 volt) Pipe size, BTU rating of boiler (input). Pressure drop would be good to know but you may not have that.
The old valve is a White Rogers, still in business. If you find the right supplier they can match that up.
Your problem will be finding someone willing to fix it.

Re: 60 PPM outside of "snowman" boiler
I might ask the Gas Company to perform the test while you are present. Since the man taking the test does not need to pay thousands of dollars for a replacement boiler, then he has no skin in the game. In the technicians opinion, you are probably some cheapskate landlord who does not really care about your tenant and are just looking for the rent check to be there on time. By showing interest in that testing procedure and being present for the test, and observing where the test sampler was located, you may find that the system is operating just fine.
And how ofter does the tenant put his nose within a few inches of the sampler location? I might test the air a foot away from that location, that is more likely a better sample of what is actually in the air the tenant is breathing. 60 PPM of carbon monoxide exposure over an 8 hour period is over double the exposure recommended by OSHA for the workplace. If there is actually 60 PPM measured at the bedroom area, and you can attribute it to the snowman boiler, then it is time for it to go. If you get 60 PPM at the fire door vent opening after only 1 minute of operation and you can illustrate that the chimney is not properly drafting until the chimney gets up to operating temperature after 15 minutes of operation, then your gas company tech needs to be schooled on the way the combustion process works on older equipment.
I would do nothing and call the gas supplier and tell then the problem is corrected and request another test be preformed while you are present. After the boiler is operated for 15 minutes the test can be performed at a location at least 1 foot away from the boiler exterior. I will guarantee you there will be less than 15 PPM measured by any meter under those conditions, if the system is operating properly.
Re: Dry Fire Failure? Water Feeder Options?
For those not familiar, the Dunkirk D247 is the same as the Utica J series, currently in version F and called JF.
Most jurisdictions require CSD-1 controls on boilers this big, which involves two low-water cutoffs. But the D247/JF does not appear to have the proper tappings so the installer can use probe-type low-water cutoffs for both the primary and secondary controls, with the probes extending into the boiler section. These boilers have only one probe tapping- which is better than the Weil-McLain LGB, which has none- but the secondary has to be a float type, with moving parts and their inherent unreliability.
In a commercial application, generally someone has the responsibility to blow down the LWCOs. But on residential, many times the blowdowns don't get done. This can lead to dry-firing.
@Fishin_Rod , where are you located? And can you post a pic of a couple radiators (with covers removed)?
Re: Why Is It So Hard To Hire A Contractor?
I had this thought the other day, I think it is a lot more people in project management roles and higher up management that either should know better or aer intentionally scamming trades that don't budget enough time or money or both for the work they need done in their project then expect the trades to fix it by either sacrificing their personal life or being paid fairly for their work. This makes people who are considering trades that would be good at it see this happening early on and run the other way to do something else where they get threated better. Until the industry fixes the way it treats trades they will not be recruiting new people which just makes the problem worse.

Re: comms between LWCO and water feed?
If all the high tech electrical / electronic gadgets are OK the VXT valve or manual bypass valve may be leaking.

Re: KBR 42 3 Bosch Greenstar
@GGross do you think poor water quality could cause a leak in two years time? I’m not exactly sure how to test for a leak in the heat exchanger without taking it completely out…
I will say that the boiler has been firing up consistently for over a week now- we haven’t had it shut down. I can’t figure out what it was.
I have an ejector put in the lower level that the drains feed into. At one time there was an issue with the float and the drains overflowed with the ejector pit full. This would have prevented condensate from draining. My suspicion is that I started having issues around this time… the Condenstate trap was full of sludge when I cleaned it. Perhaps it just took awhile for everything to get cleaned out and running normally again, with a few instances of that error code even after it was cleaned. It appears to be back to normal now.
I appreciate everyone’s responses and help.
