Master Venting for Anthratube

@ November 14, 2002 9:10 PM in Piping in second steam boiler

from the way you describe its operation, I'd treat it just like an oil or gas boiler. When the draft fan shuts off and the fire slackens, you will still be circulating some steam thru the system. As long as there is steam in the mains, the main vents will remain closed. The steam should keep circulating all the way out to the end of the system. For this to happen, the steam pipes must be insulated and the main vents properly sized. You can get sizing charts- and also experience Dan H. doing what he does best- by ordering Dan's "Dead Men's Steam School" video and workbook.

How is your heat exhanger

@ November 14, 2002 8:57 PM in TMH on 2 pipe steam

piped to the boiler? Are you sure you're circulating the water thru enough of the boiler to pick up sufficient heat? The connections should be as far apart as possible. To Learn More About This Contractor, Click Here to Visit Their Ad in "Find A Contractor"

he had us heat his addition with Orifice Vapor. We used Slant/Fin Multi-Pak-80 fin-tube baseboard with the H-6 steel elements. The same thing can happen to you. Go for it! To Learn More About This Contractor, Click Here to Visit Their Ad in "Find A Contractor"

big vent on the main and one on the return. These are Gorton #2 main vents. No vents on the convectors. To Learn More About This Contractor, Click Here to Visit Their Ad in "Find A Contractor"

recently had a similar experience on a Trane 2-pipe orifice vapor system with convectors. We were the fifth contractor he called, and we were also the last one. This one didn't have a leaky boiler- the system venting was all wrong. You don't put vents on Vapor radiators (or convectors).

@ November 14, 2002 8:00 PM in Help with an old vapor system

the equalizing line between the Return Trap and the dry return (if there is one). This is usually a 1/2-inch pipe. If this line gets hot right away on a cold-start, the Return Trap is leaking steam into the dry return, where it comes out the air-eliminator trap. If the Return Trap is shot, remove it and replace the Pressuretrol with a Vaporstat that cannot be set higher than 1 PSI (unless the boiler already has such a Vaporstat). Set the Vaporstat so the boiler pressure will not overcome the "B" Dimension (height of lowest part of dry return above boiler water line). 30 inches of "B" equals 1 PSI. The Return Trap was developed in the days when boiler pressure could not be closely controlled to 8 ounces or so, the average maximum pressure for Vapor systems. But now we have Vaporstats which do the job nicely! To Learn More About This Contractor, Click Here to Visit Their Ad in "Find A Contractor"

I did that with a Dead Man's Ammeter

@ November 14, 2002 7:29 PM in Setting anticipators

This old GE belonged to an old-timer electrician near where I grew up. He was one of my early mentors. I bought it when his business was closed after he became a Dead Man. I'll NEVER get rid of it! This one took a few more turns of wire to make it read accurately. I checked it on my boiler primary which is rated at 0.2 amps, then on several others with different amp ratings to verify its accuracy. R.I.P., John Gamber.

Boiler Room Piping

with two very nicely painted radiators. These were made by Reading Radiator Co. in (you guessed it) Reading, PA. They're ornate 2-column units, but more of a Grecian than Florentine design.

@ November 13, 2002 7:44 PM in Need Opinion-Hot Water Boiler

I'd get a second opinion if I were you. Try the Find a Contractor page of this site to locate a real Wethead. I'll bet most of them would love to see that Mills boiler! According to Frank Gerety, writing in his excellent book "How to get the Best from One-Pipe Steam", the Mills boiler is one of the all-time best designs out there. It's a cast-iron water-tube boiler with a lot of heat-transfer surface. I can't understand why the oil techs you use would refuse to service that Mills. Maybe you need to switch oil companies.

@ November 13, 2002 7:31 PM in Timmie and others...Anticipator settings....Boilerpro

but since I'm way over on the East Coast, this'll have to do ;-) The one thing I try to do on every system I work on is to MEASURE THE THERMOSTAT CURRENT. I've found a few that were different enough from what the manufacturer specified as to really throw off the cycle lengths. I usually start from the thermostat current rating/measurement and go from there. On steam or vapor, if the system heats slowly I first check the venting, then the firing rate and insulation. On gravity hot water systems I've found that insulating the flow mains and leaving the returns bare can speed circulation, as it maintains a greater temperature difference between flow and return. I'm reluctant to increase the cycle length to compensate for a slow-heating system, because this wastes fuel. I always try to find the cause of the sluggishness rather than Band-Aid it. Many times, when the system is straightened out, I can reduce the firing rate and save the owner even more fuel, reducing short-cycling in the process.

the jacked-up 47-2. The boiler is an American-Standard from the 1960s. It looks like it's in decent shape- we'll probably just repipe it with a proper header and Hartford Loop, rather than replacing it. To Learn More About This Contractor, Click Here to Visit Their Ad in "Find A Contractor"

look closely at the 47-2 piping to the sight glass. It's carrying the water level about 3 inches higher than it should. I'm sure that was done to keep the screwed-up Hartford Loop under water so it wouldn't bang. To Learn More About This Contractor, Click Here to Visit Their Ad in "Find A Contractor"

Cranked the pressuretrol down

@ November 13, 2002 6:31 PM in H.L. Mencken Lived Here (Steamhead)

cleaned out the feeder and replaced the main vents. This Gorton #2 is behind a latter-day A/C duct, replacing a Hoffman #75 that wasn't on a nipple and had flooded out so many times that it jammed shut. Finally, the heat reaches the back of the house as fast as it gets to the front. I put a Hoffman #4A on the front main, which is only 10 feet long. The back main is 50 feet long.

When you find the image, click Add, then OK. Finish typing your post, check the box next to the Attachments button if you want the image to display automatically, then click Post. That'll do it. The Moline was one of the nicest vapor/vacuum systems ever designed. It is covered in much detail in Dan's "The Lost Art ofSteam Heating Companion", available on the Books and More page of this site. If the air trap doesn't work, one or more Gorton #2 vents will work fine, as Noel suggests. To Learn More About This Contractor, Click Here to Visit Their Ad in "Find A Contractor"
