drop headers

Steamhead

on a Columbia. This one has a regular union on the horizontal rather than a flange, but it still went together very easily. There was no problem with low mains on this job, but we still went with the drop header since it's so much easier to assemble.

all our boilers are drop headers

just go as high as you can, swing joint sideways, swing joint down,,go as low as you wish but stay above the boiler..use as big a pipe as possible..we like 4''. putting a flange in the middle of the header and in the middle of each riser makes it pretty easy..i tried posting a picture but no matter how hard i tried the attachment wouldn't attach...

Say Gerry,

What do you use for dope on your 4 inch. Just finished putting together some for a Dunkirk, 247 and had a few leaks to take care of. One definitely seemed to be bad fittings....was almost able to turn the nipple into the elbow completely by hand.

4\" fittings

we used teflon tape, then rectorseal. it works great

steve_6

hey BP

how do you like that boiler?

[Deleted User]

hi BP

yup. i work with steve, and the tape and dope works out best for us..we had one joint that was sloppy for some reason and i used ''canuke dales'' trick and put cotton first aid gauze then rectorseal dope on it,,worked well, just like he said it would..

there is a skim valve

off the opposite side. weve found that if we tape heavy then dope the plugs and dont go nuts putting them in, that they come out next season without trouble. we take them out each year to service the boiler in order to get the spray tube into the boiler to **** out the ''mud'' from the bottom so we get better heat transfer..course, if they decide not to get it serviced or call us for it,,well...

247's

It was my first 247- 500,000 input, CSD-1. Really seems to steam nice, even with very little cleaning. Also, really heavy castings, so I expect it's going to last a good long time. (How many 1,000 lb plus 300,000 btu steamers are still out there). Assembly went well, especially since this was first boiler i had to assemble. I have always used prepackaged boilers because buildings around here are not that big and I use multiples for commercial and large residential. I am going to replace the wiring harness today because it appears to have an intermittant connection. Mark at Dunkirk kept at it until we got the right one (THANKS MARK!!!). Only real problem I encountered was that the manual reset probe type secondary LWCO was often cutting off the burner before the fill would operate. It appeared to be related to two things 1) the tapping for the probe LWCO is too high in the casting when using a no. 47 on the guage glass and 2) I was using an U 24 elctric fill valve that has a dwell period (delay ) built in. I am swapping out the fill valve today for a 101A that has no dwell, so we will see how things go. I've been told they are working on revising the castings to improve efficiency and, hopefully, to correct this by providing more tappings. Will also be doing my final check out, so I'll report back later.

WE use lampwick and Rectorseal #5 *(Yellow goo)

Drop headers....hmmm I've done a few. They become addictive

Sealing.....

I make all the guys who work with me on jobs do a dope, teflon,thin coat of dope procedure. They haven't had the pleasure of trying to remove something someone put in with just dope alone.(Mr.Milne!)
Anything I put together has to come apart at some point, whether it be by me, or someone else.(if I did the original job properly or, if I didn't do the job right...for free, so it only makes sense to make it easy!) This was something I learned from my mentor. He always made sure it was servicable. After all, that IS ultimately our job, right?

Dropped header Question.............

I noticed that in the dropped header on the second riser the the drop enters on a branch giving you a bull head situation. I thought this was a bad idea? what is the reasoning behind this...is this an exception?n Will dropped headers work on 1 riser? kpc

Steamhead

Technically it is a bullhead

but the steam is already flowing from the other riser toward the steam main takeoffs, so the steam from the bullheaded riser only goes one way. Bullheading a tee and expecting the steam to go both ways is where you get into trouble.

A drop header is still useful if you only have one riser to the header. If the steam mains are too low, you can use taller risers from the boiler to the header to help dry out the steam, then drop into the header at whatever height your steam mains are. In this setup, the mains and header only have to be higher than the boiler itself.

That's why I use unions on water heaters and even steam boiler

headers. This way, the fine header that we build becomes part of the steam system, and is VERY unlikely to be cut out by some butcher on the next replacement boiler (it may not be you). Mad dog

Check this out Kev....a double/single drop header , which I used

on a wacky job where some, local, meatball plumber decided to not only move the steams across the basement, but also dropped them down to about 5 feet off the floor. No one could fix it. It went off on low water on every cycle and then flooded when the water came back. I Went as high as I could with the 3" risers then dropped down in to 2 separate equalizers anh hartford loops. It was just a natural to do it this way. then I put a Vaporstat on it. Solved all problems...and it was fun. oops wrong picture I'll try laterMad Dog
