@ December 3, 2013 10:08 PM in Got an estimateWhat exactly is included in the estimate-replacement, or repiping? Is the boiler leaking?
A knowledgeable steam expert should know by looking at your system, what has been done wrong.
If a replacement, then make sure that you measure the EDR (do a search here), in order to properly size the boiler. If the boiler is not leaking, and is the right size, you could have the supplies repiped with a drop header, which will make the next boiler much easier to install.
We recommend following the boiler piping instructions at a minimum, and someone will have to skim the boiler which can be done by you, to save the installers's valuable time.
It looks like your return should be dropped lower as well.
You can remove the insulation, and then reuse it. Get a good low pressure gauge while you are at it, and plenty of good main vents.--NBC
@ December 3, 2013 10:01 AM in $125.00 for a 6" ell ???This could open up a discussion on the possible merits of welded headers, and how they could be used in a way, which does not damage the boiler block, eg, drop header, and equalizer top only, long runouts from supply risers to header, supported completely by the ceiling, etc--NBC
@ December 3, 2013 9:57 AM in New boiler noisesI had that noise with our old atmospheric boiler, equipped with variable shutters on the burner tubes. Somehow they would get out of adjustment, and the flame would light inside the burner tubes, making a loud roar.
Something may have changed from last year. Are there any new exhaust fans or vented dryers since then?--NBC
@ December 2, 2013 11:13 PM in Carbon Monoxide Issues - HELP!It's ironic that the fire inspector is primarily to blame here, for recommending non approved intake, and exhaust venting.-NBC
@ December 2, 2013 10:37 PM in Trial for ignitionHas he any idea about the repetitious short firing?--NBC
@ December 2, 2013 4:32 PM in Hidden steam leak between floorsIt might be a pipe rubbing against some wood. If it were leaking, then I would expect some signs of moisture by now.--NBC
@ December 2, 2013 4:28 PM in Surging Steam BoilersPictures will be much easier to see, and Rembrandt that things are not always to plan. I don't see an equalizer on your elevation. What pressure is the boiler running at?--NBC
@ December 2, 2013 12:23 PM in 3 unit building, one steam systemCan you post the details on the Landlordstat, as steam systems react to different thermostats in different ways-good and bad. A better choice would be a Honeywell Visionpro thermostat with remote sensor in the cooler part of the top floor. Thus the control unit could be under lock and key accessible only to you.
Definitely, check your main vents, which are probably near the boiler, on the return. For economy, you want maximum main venting, and slower radiator venting, except on the top floor (if they are slower to heat). The goal is to have steam arrive at all radiators on the top floor simultaneously. A low pressure gauge (0-3 PSI) will tell you when you have enough main venting, or if you are paying for extra fuel to squeeeeeze the air out of constipated undersized/inoperative main vents.
These 1-pipe systems can be quiet and economical if properly maintained at ounces of pressure.--NBC
@ December 1, 2013 9:31 PM in troubles with a new installPeerless recommends arm&hammer washing soda, followed by lots of skimming.
I would only put water in it, so you don't have a layer of oily diatomaceous earth insulating the bottom of the boiler from the flame.
Double check your pressure with a low pressure gauge, as the supplied pressuretrols are notoriously inaccurate.--NBC
@ December 1, 2013 9:18 PM in NEW STEAM BOILER IS BANGING! HELP!I don't see any errors in the piping, so perhaps skimming will cure it and very low pressure, as this is a trapless system, which may need orifices to restrict the steam to just that amount the radiator can handle. I can't think of the name for it or you could be reading about it in the library here.
Get him to replace the pipe from pressure relief valve to the floor, so as to prevent any accidents.--NBC
@ December 1, 2013 9:10 PM in Rezeroing 3psi gauge?I think your theory of standing water in the pigtail being a little unbalanced and causing a slight vacuum holds water.--NBC
@ December 1, 2013 8:59 PM in NEW STEAM BOILER IS BANGING! HELP!Post some pictures here of the boiler and it's piping.
What pressure is the boiler running at?
More skimming will be required, and you should be able to do that, (do a search here for details). You will also want to flush out any chemical which he may have put in the boiler, before it becomes welded to the bottom. The only chemical in the boiler should be H2O, unless you have a Chloride problem in your area..--NBC
@ December 1, 2013 12:05 PM in Basic Safety QuestionYou could flip the switch on the boiler as well. Sometimes the valves do not close all the way.--NBC
@ December 1, 2013 12:01 PM in Steam Boiler FloodingThe first thing to do would be to check the operating pressure, and see if it can be stabilized under one PSI. You probably have an old vapor system, whose traps, and vents have problems with higher pressures. Installing a 0-3 PSI gauge will show you what your pressure is. Have the pressuretrol removed, and clean the pigtail. A vaporstat will probably be needed for the future.
While you are there, test the LWCO, and ensure it will cut off the burner when you flush it. The next step would be to run off the city water make up feed with the inlet valve, and check on the operation regularly in the next few days.
Post a few pictures of the boiler, and it's piping, and the radiators, and valves, and traps.
What is your location?--NBC
@ November 30, 2013 11:43 PM in anyone recognize this radiatorWonderful rads, and I believe from someone here that you can put a tape measure around them for one dimension, and multiply by the height.
It looks as though they are steam only, with not top interconnection of sections.--NBC
@ November 30, 2013 9:11 PM in radators how much tilt?Just a little bit of slope is necessary to get the condensate to flow back to the valve.
Don't tilt too much as the condensate should gently flow back underneath the steam.--NBC
@ November 30, 2013 9:05 PM in Replacing a Pressuretrol with VaporstatThose old valve leaks can usually be cured . Most leaking occurs through the packing nut underneath the handle. The packing string in the form of graphite impregnated string can be replaced by unscrewing the packing nut, and digging out the old packing with a pointed tool, and then winding new around the stem of the valve. In my early days with our system, I used some old shoe laces as an emergency fix-those were the days!.--NBC
@ November 30, 2013 8:54 PM in Do I need a main vent that opens soon after pressuretrol cuts off burner?Maybe if you could extend the antler/Menorah/manifold out farther, the vents would cool down more quickly.--NBC
@ November 30, 2013 6:12 PM in Squick - how much and quite frankly how ??The theory behind Squick is that it will absorb the oil on the surface, and then drop down to the bottom of the boiler, and insulate the section bottoms from the heat. Gradually a little bit of Squick will come out when you repeatedly blow out the bottom drain.
When our boiler was replaced, there was a lot of mud in the bottom, and it may have been old Squick.
A better method is to skim the boiler, removing the oil, instead of submerging it.
Do a search here for skimming, and arm&hammer washing soda.--NBC
@ November 30, 2013 11:03 AM in troubles with a new installSometimes it takes quite a while to get all the oil out.--NBC
@ November 30, 2013 10:57 AM in Wet Return:Replace?Here it is. When the pipe is connected like this to the return, the oily water splashed up into the port will remain there with the oil on the surface in the vertical, and never overfilling as the level remains at the boiler waterline. Once a month when the LWCO is flushed, the skimming valve can be opened as well and all the surface oil will drain into a bucket.
One great advantage of the drop header, is in its separation of more oily water from the boiler, and there should be a valve in the equalizer to drain any accumulation off there as well. If 5% of the surface oil is trapped in there every firing! over a period of time, all the oil will be removed.
Looking forward to receiving your email when your installation has finished.
