Hello all,

I am trying to find a manual for an American standard e-409 series 1bn-j1

I'm trying to find a steam boiler with similar characteristics for replacement, all the info I could get was the model and series.

Thanks in advance

    Even if you find the information your looking for it won't help.

    If you looking to replace a steam boiler the first thing to do is to calculate the EDR (square feet of steam) of all the radiation in the building. This will determine the correct boiler size.

    There is info on this site and many on here to provide help with that .

    That's just the first step.

    Older boilers were almost always way oversized to even if you knew the boiler rating all it would do is steer you in the wrong direction

    The size of the flue will give you an idea of the BTU input.

    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    Two btu per sq ft for degree difference for a slab

    @Mail4tommo , can you post a pic of the boiler, the piping around the boiler and a couple radiators?

    Have you ever piped in a replacement steam boiler before? This should not be taken lightly. are there any special designs to this steam boiler? Is it one pipe or two pipe? are there any steam traps? Are there any steam vents on the main pipe or on each radiator? Could it be a vapor system where you don't want the steam pressure to go above 12 ounces of pressure per square inch (less than 1 PSI) or is this going to operate at 1 to 2 PSI? This all makes a difference and just getting the same boiler size as the old one may be adding to a problem in-stead of fixing a problem. I like this case of the boiler room detective where point # 7 states "Assume the boiler piping is wrong" until you verify that it is not.

    After you make that expensive repair and you still have the same problem, What will you check next?

    yes many many lgb's and many 88's. I was an installer for years not the guy who purchased the units. So I need to get back out there to measure the radiators. So Radiation needs to be confirmed.

    It's 2 pipe , going to a small receiver feed tank.

    running on a 0-10 pressuretrol,

    I wanted to know the water content inside the boiler

    Actually, the water content will not matter if you do the near-boiler piping as instructed in the manual. But there are those who read the manual, can’t follow the picture, and still get it wrong.

    Peerless published a great reference book you should look at called The Color of Steam.
