@ August 17, 2014 2:22 PM in Gas Piping - teflon tape

inspectors do not allow Teflon tape on gas piping. Doesn't matter that NFPA 54 doesn't specifically prohibit it- they will not pass a job with taped joints. Many contractors sidestep this by using CSST- we do not, for reasons we've discussed before.

If we see gas piping with Teflon tape, we know it was probably a DIY job.

Your quote

@ August 16, 2014 11:20 PM in New heating system

"choices presented were  new high efficiency boiler with hydrocoil with
proper zoning of existing and addition vs variable speed high efficiency
hot air heat requiring three furnaces which is less expensive"

You need to talk to some people who know a thing or two about comfort. Your current contractor has no clue. Where are you located?

None of the things you're proposing

will equal the comfort or efficiency of your hot-water system. Why not keep it? 

First thing to do

@ August 15, 2014 9:26 PM in Yet another boiler sizing question from a newbie...

is change the Hoffman vents on the 70-foot main and the return line to Gorton #2 vents, which will vent a lot faster than the Hoffmans. The 30-foot main can keep its Hoffman. This should get steam out to the ends of both mains at about the same time, and the longer main will heat up a lot more quickly.

Here are some classics

No response from Burnham yet?

I guess we shouldn't be surprised-.......................

@ August 11, 2014 10:47 PM in Columbia Boiler Conversion Question - Baltimore

and you'll see our information as well as some pics of a larger job we did near you. Call and leave a message, or send us an e-mail... we're not in the office much.

For radiator refinishing, the only company I know of is Baltimore Finishing Works, 410-235-7326. They're over in Remington, and do great work.

Looking forward to talking soon!

Where are you located?

@ August 11, 2014 10:42 PM in Dunkirk Series 689 Manual

there should be a pro nearby who can help you with that system- not just the boiler, but the system itself. 

That boiler

@ August 11, 2014 1:35 AM in Columbia Boiler Conversion Question - Baltimore

will run very well with a Carlin EZ-Gas burner. We've converted several of these 3-section Columbias, and as long as the boiler is in good condition (which we determine before converting it) and the conversion is done properly, there's no problem.

And we're located in Baltimore. Let's talk.


@ August 8, 2014 10:57 PM in Replace gravity with pump in condensate line?

I'll be in Milwaukee over Labor Day weekend. If you want some more eyes on this thing, let's talk.

Too late

@ August 7, 2014 8:21 PM in Burnham has tested Beckett gas burners in oil-fired boilers

I saved it.

To "USB" (a.k.a. "Harper111"?)- people are going to convert your boilers anyway. You might as well get behind this like some other manufacturers have.

What are you going to do when increasing energy-efficiency standards outlaw the sale of atmospheric gas boilers like the Independence? "Blown Gas", as it's called in Europe, will rule. If you ignore this now, you'll have a LOT of catching up to do later, during which time you will lose a LOT of market share.

Think about it. The gas-fired MPO and MegaSteam could help save your company.

Burnham has tested Beckett gas burners in oil-fired boilers

@ August 5, 2014 9:56 PM in Burnham has tested Beckett gas burners in oil-fired boilers

Folks, I didn't believe it either. But here it is, straight from Beckett:

At the moment, only certain V-8 and MPO boilers are on the list.

The question is, why did they say using anyone's gas burners in these boilers voids the warranty when we mentioned using Carlin's burners in them?

Bet we don't hear an explanation from Harper111................

are you located?

That's what I thought

@ August 1, 2014 11:28 PM in Webster - Two pipe vapor with return trap: New Boiler

a ceiling-level header. Don't seem to see them too often, but the ones I have seen were all on Vapor systems.

These ceiling-level headers will work fine if properly piped. I've attached a couple pics of one we re-used, on a hybrid Dunham/Hoffman Vapor system. The existing header was 4-inch and the Weil-McLain 4-80 calls for a 4-inch header, so we just piped into one end, took the equalizer off the other end and plugged the remaining riser tapping that was in the middle of the header.

The 80 series boilers can be fired with either oil or gas. A 4-80 is good for 1238 square feet EDR. If you have more than that, you'd go with the 5-80 at 1608 square feet. The 5-80 can use the same single 4-inch riser to the header, so if that header is 4-inch, it can be re-used.

Leave the Return Trap piping as it is, unless the Return Trap is no longer working. Use a Vaporstat to control the boiler pressure. And I'd suggest using probe-type low-water cutoffs, as we did on this job.

Looks like there are two headers on that boiler

@ August 1, 2014 11:01 PM in Webster - Two pipe vapor with return trap: New Boiler

the lower one is completely wrong. Can you get a picture of the upper one, to show how the steam mains tie into it? 

Sure about that model number?

@ July 31, 2014 4:35 PM in Cast Iron chambers needed

This would have been an A-3 series set up for pressure-firing, but the way the model numbers worked on this series, you're describing a 13-section boiler. Do you know how many sections it has?

The answer is simple

@ July 31, 2014 11:50 AM in Another Steam Boiler Sizing Concern

At the moment, I have both charts for the Columbia. For the Intrepid I only have the one chart. Slant/Fin did change their Intrepid chart recently but their rated efficiencies went UP with the change, rather than down as with the Columbia. Bottom line is, we always work from the chart with the best efficiency.

In many cases the incoming gas service and meter are fine, especially on smaller jobs, but we have to check out each one to be sure. If upgrades are needed that's the utility's problem, and around here they take their sweet time getting to them. If this turns out to be an issue, you can always install a new boiler with the oil burner first, and change it over to gas when the service upgrade is done.

We choose our boilers based on how close they are to the load, how well they will fit the available space and how well they are supported.


@ July 30, 2014 9:17 PM in One or two pipe steam?

doesn't look like anything but a standard return elbow. There are orifices in the radiator shutoff valves, so the steam will not reach the return lines unless the pressure gets too high.

This system needs a Vaporstat to control the boiler pressure, not the usual Pressuretrol. The latter cannot limit the pressure to less than 1 pound.

If you can find a radiator valve that someone hasn't slathered paint all over, see if you can see a name on it. Also take a picture of the boiler and surrounding area.

That's probably "Orifice Vapor"

@ July 30, 2014 3:16 PM in One or two pipe steam?

unless there's something inside those radiator return ells. Post some pics of some rads so we can have a look.
