assemble push nipple boiler

Bill Nye_2

pipe dope, I use Hercules Pro-dope with good results. Just a light coat for lubrication.

Clean up all the rust with steel wool or fine emery cloth. Make sure the nipple is started "square", draw up evenly and if you have to hit it with a large hammer make sure you have an oak 4"x4" betweem the cast section and the hammer.

If things aren't pulling up just right, back off and make sure everything looks aligned. Brute strength is not always better than a little finese. Take your time, enjoy it, it is way funner than sitting in a windowless office [I can only assume, I never had an office job , just think I wouldn't enjoy it] Good luck, let us know how it went.

dunkirk D247 boiler

We are going to start this job next week and am looking for "tips" on putting together these boiler sections with push nipples. Pipe dope or leak-lock on the nipples? Anything special about drawing them together? Thanks for the help

Read the ....

instructions first. It may sound funny but the maufacturer hides in them good tips to make things go easier. Read them over a couple of times and highlite the important directions such as how to pre-clean the nipples and openings, recommendations for lubricant and if it's supplied, setting the nipples square in the openings,setting the first two together for a good, plumb and square start, etc. Also, I've always set mine on a lenght of flat, stock steel the lenght of the boiler and add an inch or two, it allows for less drag from the cement base as you draw the sections together. It is a fun project when things go well, but I prefer to borrow the hydralic press kits on large units to provide timely gratification! Call on your salesman or area rep and let them know the day you will be doing the assembly and have them join in on the fun! Many times the salesman haven't had the opportunity to really see what they have sold out of " that big box in the wharehouse". Don't bypass the hydro test it's very important!

gotta agree

whoever you are getting the boiler from should have a press kit they will let you use. It goes so much easier that way. You may have to shim the first couple of sections to get them to line up. We did a good sized burnham steam boiler last winter and used the lube the boiler manugacturer recommended. Your supplier should have that as well. The pipe dope is only a lubricante so any will do. I like rectorseal #5. Have fun, this is the part of the job I really like

I use a little dope on the push nipples. Make sure all surfaces to be joined are clean and free of rust. Use 1.5" angle iron under the sections on both sides. This makes it easier to line up the sections and keep them square.

supply angle iron "rails" as part of the boiler package. Don't other boiler manufacturers also supply these? I can't imagine not doing so.

I've used Dunkirk boilers for years, but I have never gotten any angle rails from them for installation, and the last boiler I installed that needed to be built on the job was a WM and didn't get any rails from them either.

draw rods

Sometime back I had a job at a nursing home where we were replacing a boiler with a Burnham. I got a call from the job and was told they were having trouble drawing it together with the threaded rods that had been supplied. I told the lead guy that something must be wrong with what they were doing and thought the procedure threw on the way to the job site when I got there I saw there was too much effort being made to turn the draw nuts and was hit with a barrage of complaints about how I had not allowed for enough time to comlete the job and stay in our budget(as usual always the bosses fault) I thought for a minute and grabbed a zoom spout oiler off the techs belt who was mounting the new controls on the wall and put a slight coat of oil before and after the nuts had them backthe nut off and oiled the dry part where the nut had been they retightened the nut and the sections drew in like they were coated with butter.
Of course it was still my fault because I hadn't told them to do this in the first place . Bottom line line we finished in less time than I had allowed for on my bid.
Make sure everything is lubricated properly

we've installed a few of these boilers. The instructions are pretty good. the toughest part is leveling the base. You don't need a press to assemble the sections, just the draw rods they give you and a good set of combination wrenches. They supply GRIP for the push nipple sealant. It works well.Here are some pictures.
