    Well, let's see-

    1- cleanout cover not sealed- not sure if the soot is new or old

    2- gauge not working (unless the boiler was at pressure when you took the pic)

    3- two pressure controls on one pigtail

    Where is this?

    Pressuretrols not level could be a problem as well.--NBC
  • exqheatexqheat Posts: 31Member
    The operating pressuretrol is level. rotating until arrow is lined up. as pigtail rotates, pressuretrol will remain level.

    Good comments, but not the problem. Keep trying. I was amazed. how did I find out.

    Common ED. You can handle this one.
    Hint. Look at installation instructions.

    No sight glass for water level????
  • JUGHNEJUGHNE Posts: 6,438Member
    No sight glass shown.....could be a bad steam to water conversion.
    Not enough pictures to give a good diagnosis.

    The only install instructions shown refer to the pop off valve.
    It looks like one on the rear right top of the boiler.

    The steam piping being wrong is just a given for something this old.
    Might not be a problem given the steam chest of the boiler.
  • FredFred Posts: 8,201Member
    I don't see a water supply either but it could be anywhere.

    Hello, we are hanging by our fingertips with baited breath.....what is the next clue ????
  • exqheatexqheat Posts: 31Member
    Well, I was testing for pressure with no results. So I took the tree apart. The Siphon (pig Tail) was clean. I changed it anyway. I put a test blow off on the tree. Struck up the fire and nothing came out of the blow off valve. I took it all apart once more. Thought the boiler path was clogged. I put a 24 inch 1/4 drill down the hole about 8 inches, and I could swirl it around. I said to my self, this hole is to the fire chamber. So where do I get steam to feed the tree. My only thought was to put a tree in where the pressure dial is located. Now I have the problem of removing the gauge body without breaking it off. Now what do you think.

    Tee off the blow off port?
  • EBEBRATT-EdEBEBRATT-Ed Posts: 6,307Member
    @exqheat

    I have a hard time figuring out what your talking about but the tapping your in for the pressure controls goes to the boiler water, it does not go to the fire box.

    You could use the gauge tapping in the front where the square gauge is.

    If you have a 1" pipe tree for a low water cutoff on the right hand side you could put it on top of that.

    You could also drill and tap one of the steam lines coming off the boiler I think they are 3" ips drill and tap a 1/4" hole in it on the boiler side of any valves.

    You could take the safety valve off and put a tee underneath it for the controls, put the safety valve back on top

    Maybe its leaking somewhere like at the joint without the tape
  • FredFred Posts: 8,201Member
    If that steam riser, on that end of the boiler is water side of the of the boiler, that control tapping should be as well.
  • exqheatexqheat Posts: 31Member
    the gauge on the front registers pressure, but nothing out of the open valve on the tree. ??

  • GrallertGrallert Posts: 358Member
    Are you sure the gauge in the picture is working? Is the new gauge on the control manifold reading the same?
  • FredFred Posts: 8,201Member
    How do you know you had any pressure in the system? The gauge, on the front could be bad and just bouncing loosely around. How long did you wait after firing the boiler? I wouldn't expect you to see measurable pressure until fairly late in the heating cycle.
  • B_SloaneB_Sloane Posts: 36Member
    pressure tree should be 3/4" with clean out plugs
    the controls each need a pigtail
    no pass inspection in new york !!
  • exqheatexqheat Posts: 31Member
    So where is the 4/3 port?
    John Cockerill
  • exqheatexqheat Posts: 31Member
    The front gauge registers, the top no, when I open the blow off on the tree, nothing comes out. So where do I get a port to the tree that was built with the boiler?
    John Cockerill
  • exqheatexqheat Posts: 31Member
    No tapping on that side.

    Could it be that this boiler was built before pressuretrols were required??

    , I suppose, if it is a converted coal boiler but there are still tappings that should allow you to add controls. When you put that 18" drill bit down that hole, did it come out wet? If so, you hit water and the Tree should work.
    Where is the sight glass? How much water is in the boiler?
    How long did you let the boiler run before you decided that tree isn't working? That's a big system. I would think it has to run a good while to build measurable pressure, if it ever does.
  • mattmia2mattmia2 Posts: 609Member
    I assume you are seeing the gauge on the front go to 0 when the boiler cools?
  • JUGHNEJUGHNE Posts: 6,438Member
    Could this have been shipped as a water boiler without steam trim. Only the gauge got changed out.
    There could be tapping under the jacket for steam trim.
  • exqheatexqheat Posts: 31Member
    Not a conversion from coal. I would like instructions to tap in front. Cannot get jacket off without removing front pressure gauge, which works just fine. The drill bit came up dry. The McD water fill system is fine. Tested and blown down weekly. At full cycle nothing from current port. I'm getting the feeling, I've got to rip the front pressure gauge Off. It is quite cemented. If I rip the gauge off, I can them heat the fitting to remove from the boiler and place a tree there. Of course I'll have to rewire the cables installed originally. I have no idea how many years this has been running like this. Fortunately my Exqheat control has kept it within safety range.

    Could you tap in to the piping for the lwco or auto fill to connect the pressuretroll to that tapping?
  • JUGHNEJUGHNE Posts: 6,438Member
    Could the LWCO have had the controls installed there with the sight glass?

    If you are looking for a larger tap than the 1/4" that is shown in the pictures you posted, remove the existing tree with the single pig tail and then remove the reducer/bushing that are below that 1/4" tree pipe. Also, look on the jacket, anywhere there is a "knock out" plug there is a tapping. Try removing the jacket to find other taps. Or as @EBEBRATT-ED wrote , drill and tap a pipe of fitting. And, if you are worrying about those front doors not sealing well enough, remove the doors, look to see if the "asbestos gaskets are still in place. If they are, soak the doors to soften the asbestos gasket and re-install the doors while the gasket is soft or just replace the gasket.

    I like the comment that a well balanced system never shows much pressure anyway. Exquisite Heat provides just the BTUs needed. As most equipment is over sized in an age of 10 cents a gallon, the pressure seldom becomes an issue.

    One more comment; these 2500 Mills boilers were made to fire nat gas or fuel oil however you could fire these boilers with any type of fuel, if you so desired. There is no difference between the steam or hot water boiler except for the trim that was supplied and/or installed. In my 35+ years of servicing, installing and building these boilers I never had to replace a section that was cracked or failed due to any use. They were not an efficient boiler but they were dependable and lasted a long time. There are probably unused taps somewhere on the front or rear section. you just have to look. I never liked this boiler because the jacket is almost impossible to remove without using a sawzall or cutting torch. Show a picture of both sides of the boiler to see if there are any other ways to install pressure controls.
