Boiler LWC activates quickly

Hello Steam Forum,

I have a Burnham model SIN5LNC-LE2.
When boilers starts, it only takes 10 minutes for the water level to reduce and activate the Low Water Cutt-off. You can see the water in the site glass going down pretty fast. However, the radiators don’t get hot until the water feeder fills again another two times which causes the boiler to be overfilled (per the site glass) when the water returns.

I was wondering if the boiler is undersized or heating too fast? Or does anyone have an idea why this happens?

I know that the near boiler piping is not right (according to forum, see image) and I do not have any vents on the mains (lots of air from radiators.

Also, any steam heat experts you recommend in Brooklyn to correct the near boiler piping.

Thanks

Re: oil furnace sooting extensively

Extensive sooting in an oil furnace can indicate combustion issues. Check and replace the furnace nozzle, ensuring it is the correct size. Verify proper fuel-to-air ratio, adjusting if necessary, to prevent incomplete combustion. Inspect the chimney and flue for blockages, and ensure the burner assembly is clean. If sooting persists, consult with a qualified HVAC technician to address potential issues with the burner, heat exchanger, or other components that may be affecting combustion efficiency.

Thank you AI, or captain obvious.

Re: Steam boiler sizing discussion

@Jamie Hall Yes, normal single pipe atmospheric.

And I didn't name the dry return on the picture, it came that way so I don't want any "heat" over it.

Re: Settings for Vaporstat + Pressuretrol in series?

Cheezus. Previous tech wired the LWCO and pressuretrol IN PARALLEL! 🤬 1&2on the MM 61.

I already got the new parts so I guess I can keep the old, old, old WR pressuretrol as a spare. 🙄

Neilc,

I have it.
Are you implying it's correct? I've had some of the well known steam guys on the forum tell me it's not correct.
Just making sure I understand your comment correctly.

To the contrary. He is trying to tell you that your boiler piping is horrible
