Cantankerous H.B.Smith Propane Boiler

Nevin H.

I have a small H.B.Smith Propane gas boiler that is hard to start at the beginning of the season. It automatically tries to start only 3 times. If that fails, the circulator keeps circulating cold water.

I noticed that the flame was yellow, but an annual wire-brushing removes the surface rust from the 3 flame tubes and returns the flame to blue.

If I maually restart the ignition cycle about a dozen times, the blue flame keeps burning. This tells me the repeated starting is warming up the flame Sensor to a point where it keeps the gas turned on.

Is there an electrical or physical adjustment on the Sensor,
or has it lost its sensitivity and needs to be replaced?
Or am I barking up the wrong tree?

Thanks,
Nevin

    Thanks

    I built my home in 1960 with hammer and saw.
    I installed this boiler in my home.
    I've been a repairman all my life.
    I'll keep it up until I put the house into orbit;

    worry not!

    what model ?

    and where are you ?
  • Into orbit it may go

    I STONGLY ADVISE YOU TO GET A PROFESSIONAL AND QUIT MESSING WITH SOMETHING YOU KNOW NOTHING ABOUT.

    As you keep recycling that burner gas is building up. Propane is heavier than air and you may not sense it accumulating until it blows up in your face.

    Believe an old gas man with over 40 years in that business get a professional service tech to look at your burner.

    "BOOooo"

    Best stay indoors tonight,
    for it is dark and it is cold.
    Leave the wandering tonight,
    to fearless and the bold.

    Weird sounds and shadows,
    fill the night, and seem to follow you.
    Be careful where you go tonight,
    be careful what you do.

    The slinking and the slithering,
    are dressed in orange and black.
    Look all around, behind the trees,
    most surely, watch your back.

    'Tis little bags of candy,
    that they search for, in the night.
    With flashlights, shining eerily,
    to surely cause you fright.

    So guard your candy cupboard,
    and be careful who you greet.
    Or you may hear, the frightful words,
    "Hallow there, Trick or Treat"

  • Nevin H It is not that I do not

    know the answer it is that you should not be messing with something you know nothing about.

    You will need to hook up a microamp meter and take some readings. If you give the controls involved with your boiler I will give you some advice. You can believe this if any one knows I know. You want help I am willing to help to a point but only looking out for your safety.

    There can also be combustion problems casuing your problem. Have you done a combustion analysis and carbon mopnoxide test?

    What are your voltage readings to the controls? Do you have a good burner ground? The list goes on of things you need to check and know how to do.
  • Don't let 'em goad you, Timmie

    We know you help all equally, and you want to harm no person in that house. Your advice is the best.

    You need not feel obliged to prove yourself. The guy scared all of us. Being bullheaded doesn't make him right.

    Happy Halloween.
