This is old literature, but 4 tries and lockout, symptoms are the same.

Re: Near-boiler piping : what do you think ?
2 1/2 and up is a PITA but you do what you have to do. With something like that the most important thing is to be able to visualize and know how to measure.
That job is a cinch if you know what you are doing. You measure it up buy what you can (which in this case is everything) and have a supply house cut and thread some 2 1/2 inch that you measure up > In this case you wouldn't have to.
Here is a chiller I did about 10 years ago. I was about 62 at that time. We cut back the supply and return 6" pipe and welded on 2 flanges. Ran 6" vic into the chiller.
Picture going to a job 1 1/2 hours from the shop lugging a groover and something to cut 6" pipe with all the pipe and fittings. You not lugging those tools to the roof so you would be up and down the ships ladder all day. No fun. Even with two guys it would suck.
So I spent 2 hours measuring it up and ordering the fittings. Turned my sketch in to the shop and had the pipe cut and grooved there. there.
Loaded it into my truck and went back myself. Pulled it all up to the roof with a rope myself and piped it. That's why I am a mess now.
I had the welder build the angle Iron support the same day we put the flanges on.
Its all about knowing how to measure.
Re: Oil guy couldn't fill my tank today
Check the price of propane before you decide. If it was me from what i know about propane prices I would stick with oil.
How do you eat an elephant? One bite at a time.
Its easy to come on this site and have everyone including me tell you how to spend your money.
This is my take.
Propane is going to cost $$. You would still have to remove the oil and the tanks. You can't just abandon them.
Put 1 new tank in. Make it a 330 gallon thank if they can get it down there or a 275. Your previous post said you only get the tanks filled 3-4 times a year. You can easily get by with 1 tank. Your probably getting oil every 2 months now. Once a month is a non issue.
That gets you back running.
See how that goes and then you can save up for a furnace and another tank which you may never need to add. You can have them give you an estimate for another tank and a furnace so you know what your looking at.
I understand big, unexpected expenses
Re: Help with recommendation of Gorton steam cast iron radiator vents sizes?
"The lost art" is mainly intended for contractors, while "we got steam heat!" Is meant for homeowners. However, "the lost art" is well and clearly written so it will probably be all you need.

I am very grateful for all of your advice and knowledge. I’m thankful to have this group. Bburd that’s exactly the answer I’m looking for. Thank you so much!

Re: Help with cast iron radiator decision
Let me give it a shot.
I think I can understand why you might want to get rid of that radiator in front of the window. I would. Now. What to put into its place? I presume this is hot water heat? If so, flow is not likely to be your problem, although you may have to get somewhat creative with pipe routing. This is especially true if the radiator you have there now heats the room adequately.
However, as @EdTheHeaterMan said, what could be a problem is the emitter itself. The baseboard. You really want to use cast iron baseboards if you can get them, as they will behave in much the same way as your radiator in terms of how fast they heat up and cool off. Then the second aspect is to match as closely as you can the output of the new baseboard to that of the existing radiator.
Re: Riello 40 F5 issue
Former Riello Burner Area Manager here.
Draft, draft and draft! I cannot count how many jobs I went on that DRAFT was the issue. Guys first line of defense was always "that's the draft regulator that came with the boiler". That's fine…but if you read the instructions, it says something like it's good for 25 ft high chimney. So, if your chimney is 60 ft high - then you need to go up (2) sizes on the regulator - so that 6" regulator needs to be an 8" draft regulator. I went on a RIELLO commercial burner call 20 years ago in a Weil McLain 94 Series, (2) boilers and the other boiler had an old Kewanee burner in it lol. PLUS, (2) commercial AO Smith water heaters, all (4) appliances going into approximately 3x8 ductwork breaching - NO DRAFT Regulators. Chimney was approximately 125 ft high. I opened the flue cleanout and almost got sucked up the chimney ;-D. The contactor ended up putting (2) 20" barometric dampers in that breaching ductwork to get the draft right. See, big or small boilers/burners work off the same principle!
Now FYI that 530 control is not digital - it's completely analog with a bi-metal heater for the reset. The more times you reset the control - the shorter the TFI is. So if you hit the reset button 5 times in a row - you'll be down to about 1-2 second TFI. Nothing wrong with that control - just the way its designed.
Next thing I would check is vacuum on the pump. Everyone always makes in fun of that little pump, but I've seen those pumps do the unthinkable, and I've seen them do nothing out of a 5-gallon bucket. At this point if you're grasping at straws, put a vacuum gauge on the pump. Check the pressure while you're there, if someone turned down the pump pressure - now you're probably grossly over-aired. Just reviewing basic burner set up is key on problem jobs like this. I went out to help a local contractor two weeks ago that had a problem gas burner with nuisance lockouts for 2 years straight. Carlin EZ Gas burner. The contractor had replaced (3) 60200 FR controls and (1) ignitor over the two-year period. I simply found that the burner was NEVER set up with a combustion analyzer. It was running at 100% excess air, waaay too much draft and the wrong gas orifice size. Once we dialed everything in - burner is now purring like a kitten ;-)
So, whether its oil, gas or dual fuel - big or small - same principles apply.
Re: [urgent] Is there a way to limit maximum firing rate for Lochinvar Knight boiler?
From the manual, the ramp delay allows you to limit the 6th final ramp output.
So maybe start with 5 minutes on each step, put the last one to 50% or whatever you want to limit the max firing rate to.step 1 10%, step 2 20, step 3 30, step 4 40, step 5 50% and whatever you need on step 6, maybe 60%
