@ December 11, 2013 10:32 PM in Another Twin System - 6" Drop HeaderDidn't get a chance to grab the data loggers, but the owner told me that the system is maintaining 8oz with both boilers running. I think the colder weather has finally allowed this system to level out.
@ December 11, 2013 10:09 PM in steam upstairs, hot water loop down...I would bet money that the circulator loop is not installed correctly. It should have a control to shut the boiler off before it makes steam. I would guess that the circulator is a TACO 007 that is currently not working.
@ December 11, 2013 10:03 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYThanks. We're constantly analyzing our work to make improvements. The most important part of every job is to stand back and criticize every detail. We always ask the customers if they would have had us do something different if we were starting over. If they hesitate for even a second, we'll change whatever it is that bothers them.
Pyrex piping...well, let's just say that when I finally have a steam system of my own, you may be seeing a glass system.

No drip/trap at the inlet of the zone valves. One we cracked the union open, about 2 gallons of water came pouring out. Bingo!
So, we added F&T traps to every steam main with a zone valve that wasn't draining properly. The trap in the picture needed to lift condensate 12" up in order to connect to a higher dry return from a separate main.
@ December 11, 2013 9:52 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYPop quiz! Don't look below if you want to guess the answer...
We never saw the old boiler operating, but we were told that the system suffered from major water hammer. Can you figure out why from the photo below?
@ December 11, 2013 9:49 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYDay 2 & 3
Boilers in. Piping 90% complete. Had a few fittings get lost in transit between supply houses.
We're seeing the new Carlin burners for the first time. Love the new gas valve wiring. We are thrilled that they finally added a plug-in wire instead of that terrible little clip-on guard.
Here are some teaser photos.
@ December 11, 2013 9:43 PM in Another Twin System - 6" Drop HeaderThought about it. I came to the conclusion that I would rather go 60%/60% for redundancy. If one boiler goes down, the other can keep up in most weather.
@ December 11, 2013 5:27 AM in low water cutoffMake sure the factory jumper is screwed down tight. Check the other wiring connections as well. I've had a loose jumper from the factory before. It would run for a minute, then rattle loose and shut down.
@ December 10, 2013 9:51 PM in Boiler oversizedI don't know what adjustments will need to be made. That's why it needs to be tested.
Take the time to do it right the first time and save yourself the heartache of hurting or killing somebody in the house. It's not worth neglecting.
@ December 10, 2013 9:45 PM in Single Pipe VacuumWhat about this idea?
At the end of the main, where the vents would be, you install a 24volt zone valve (constantly powered open on startup), and then a thermostatic trap on its outlet. The zone valve remains open until steam has closed the trap. The valve would be actuated by a simple aquastat attached to the steam main. Once the zone valve closes, it opens its end switch, signaling the boiler to drop into low fire, or shut off 1 of a set of boilers. This will allow you to form a positive air seal, with no chattering check valves, and a direct signal to the boilers that the mains are hot, and high fire can drop to low fire.
It doesn't divorce us from electricity, but it only uses 40 watts.
@ December 10, 2013 9:09 PM in Boiler oversizedHe wants to replace the entire burner tray, which sounds like the best idea. The sections are the same.
HOWEVER! I would highly advise that you get a professional to, at least, inspect the work before firing it up. Hire somebody with a combustion analyzer, who knows how to use it, to make the final adjustments
@ December 10, 2013 9:08 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYThe first stair landing was about 3ft by 3ft, and nowhere to tie off a come-along. Unfortunately, the stair climber was the only option. Went down with little effort. The hard part was getting the boilers ONTO the landing (down one step). The boilers are about 35" wide.
@ December 10, 2013 8:20 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYStill looks terrible.
@ December 9, 2013 9:03 PM in Regulating steam valveI always cut off the spud-side union and then get a 3 or 4ft wrench on the pipe. Never fails. Also helps to lay the radiator flat on the floor.
@ December 9, 2013 9:00 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYI still have no idea how you got that boiler up those stairs. We were tired just carrying a few wrenches.
@ December 9, 2013 8:48 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYBoiler went down a month ago, so they've set up temporary heaters.
That mysterious item (just one; we moved it around) is a very, very, VERY old water heater.
@ December 9, 2013 8:33 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYWe had been talking about the topic of thread-wicking in another thread. Here's what a pipe nipple looks like when wicked, for those curious.
@ December 9, 2013 8:32 PM in 3 Boiler Caravan - 6" Header - Kings Park, NYWell, here we go again. We're still recovering, physically, from the last 2-boiler system. Thought it would be a good idea to not get too comfortable, and schedule another one.
Original thread from contact here:
The old WM oil boiler cracked. We didn't do any of the demo. What a relief! It was enough work just getting the new boilers in. We'll be putting in a set of 3 SMITH 8S6 steam boilers with Carlin gas burners. The system has 5 zones, with zone valves on the mains. This seems like the ideal setup for a caravan-staging system. When few zones call, 1 or 2 boilers will be more than enough to handle the whole load. When 5 zones call, all 3 boilers will remain online.
We'll be removing an existing condensate tank that doesn't need to be there. It had a purpose with the older, higher water line (No B Dimension), but our smaller boilers will negate its necessity.
Going to use a set of 3 Monash #48 traps for venting. They'll take the place of 6 Gorton #2's. We'll also be upgrading all of the traps in the system; 35+ in total.
Here are a few pictures from Day 1. That point of view from the bottom of the stairs is going to give me nightmares tonight. Three 800lbs boilers + 15 steps = Jelly-legs. Thank goodness for electric stair climbers!
@ December 8, 2013 9:23 PM in MegaSteaming by the riverNot bad. Looking forward to finally being able to install a MegaSteam soon.
@ December 8, 2013 5:34 PM in MegaSteaming by the riverWhat's the warranty on the MegaSteam? Isn't it less than 10 years?
@ December 8, 2013 4:22 PM in system flood protection with Heat-Timer vents?You can also install a self-closing shower valve on the water feed. It needs to be held open in order to pass water, and will spring close when let go.
@ December 8, 2013 12:11 PM in steam boiler water issueIf you drain the boiler and the glass is still full, then the glass gauge is dirty. But, that's only one problem. Sounds like the LWCO or water feeder have an issue, too.
