EFM DF520 Install

Very nice job. Methinks easy-street is just ahead ....

Purchase a new Marshalltown triple gauge from ACI controls, The manufacturer is Marsh instruments in Ohio AND they are American made, calibrated and tested in America and have a warranty.

You will not have a problem knowing what is going on in your steam chest after you install the new triple gauge. Do not use Teflon tape use pipe dope and be sure the base of the threaded portion is clean of pipe dope before you thread it in place.

From my personal experience I can and will tell you that the Chinese made gauges are not accurate-the communist Chinese manufacturers from the mainland that do not list the name or address of the manufacturer on the gauge box or the gauge body.

I would trust the manufacturers of pressure gauges made in Taiwan(Formosa)
long before I would use the Chinese made gauges as the three round gauges
I had did not even have the name and address of the manufacturer in China
either on the gauges body/shell or for that matter the cardboard box they came in.

I will tell you that I can sleep very well and through the night with the new Honeywell
controls, the separate independent low water cut off and the new 4 inch square
Marshalltown Triple Gauge.

I also told the owner of Keystoker Don Snow and Brian at Kesytoker the Chinese gauges are not good and cannot be trusted.[/quote]

lzaharis I will check out those boiler gauges I do not want to trust my boiler to a cheap Chinese gauge and the old one I have has seen better days.[/quote]

===========================================================================

I can and will tell you that I sleep better knowing I have an excellent gauge in the steam chest and I have had no trouble with it or worries about it being calibrated correctly.
The gauge cost me a bit more than $75.00 with the tax and freight cost but the gauge came home to me from Ohio in a solid heavy cardboard carton with a foamed inner package that prevented any external damage from occurring to it.
If you look at it this way the more you spend up front on high quality controls the less it will cost you.

Here is an update on my boiler install I did not have much time this last week to get much done but I did get some of the plumbing added.
I got more of the supply line plumbed to the expansion tank.
The manifolds are installed and one of the circulator pumps I sweated some unions on the copper supply and return lines.

quick 2 cents loose the unions on supply header, not needed just un bolt from isolation flange

Nice Looking install.
Real Clean!

Thanks for sharing!

You're going to like those purge station valves, I used the same on my system, and they clear the air quick.

Yep.

Yes I know how to replace a pump. I have done it many times the reason for the unions is so I can align my flanges and keep pump facing a way that allows me to use the port for the top flange. If I had know it when I had ordered my flange kits for my pumps from Supply House that there was adjustable flange kits but I already had them and had plenty of unions so this is the way I did it.

Thanks coal Stoker .... No I am not a Tradesman but I have worked in Industrial Maintenance for years before my current job.

you got me confused how do the union align the iso flanges?

On February 28th I finally got my EFM 520 fired up and making heat just in time for the cold weather.

My wife has been very supportive of this project but she had her concerns about if it would make enough heat but now she is a believer in how much heat this makes and she loves how warm the house is.

If I can get these videos up loaded I will post the first fire.

You should have had her read the following thread,it would have convinced her of the capability of an EFM520.
From OWB to EFM520 Installed in Truck Box

You can tell her that she will only have to start worrying if all the windows are open & the wind is gusting at 30 mph.

Good job on getting it set up,hooked up & fired up.

Thanks....Yes I could have had read that post but it was priceless to see her realize how warm that boiler makes the house.

Here is one of the video.

If it sounds like an EFM...
It likely is an EFM.
It looked like & said EFM,so the sound was just verification of the fact.

I will up load more later I seem to keep losing the web page.
