It's been a while, but if I recall here in Utica, NY the code called for one firomatic at the tank/tanks and one at the burner. The tank/tanks had to be no closer than 10' from the boiler/furnace. If there were two tanks or more they had to be enclosed in a masonary wall. We've even seen the area containing the tanks enclosed in sand, the outlet from the tanks piped through this wall then a firomatic installed. Often thought that this was one of Steamheads "disasters waiting to happen".
Also, Ice could add to this, but, I seem to recall that the Mass code called for a Firomatic electrical switch installed directly above the oil appliance to shut off the electrical supply to the appliance in the event of overheating.

Nice job

@ April 3, 2014 8:41 AM in what is it? where does it go?

Good thorough work. I'm sure you have an AFG burner, Utica uses the AFG-II for their direct vent application. Most of the guys here would reccommend you replace your 0 to 30# gauge with a 0 - 3# one, that will give you a more accurate reading of your system pressure. You need very little  pressure to make your system function, probably 11/2# max.
Don't delay the combustion test too long, it's amazing how quick you boiler could soot up if everything is not right. All that great work you did could require repeating.

Following up on Steamhead's comments - If the target wall has been lying in the bottom of the combustion area there is a good chance that the boiler flues will require brushing & vacuuming prior to your installing the kit.Also, I don't think I would purchase the mounting door insulation kit if yours is in acceptable condition just to get the observation door plug. If the one you have will not stay in place just leave it out. Next you should have your boiler properly "set Up" by someone with a combustion analyzer - very critical for clean efficient & safe operation.
I checked with my good friends at Utica tech support. They tell me the door "Plug" by itself is not available. Also with regard to which burner you may have, I assume a Beckett AFG II, they tell me that with a Reillo or Beckett AF-2  they recommend removing the target wall. Hope this may help.

Target wall

@ March 30, 2014 8:44 AM in what is it? where does it go?

The first picture is the "target wall", it goes up against the face of the rear section in the combustion chamber area. You can get a replacement kit - Part #5611508  
called target wall & insulation blanket kit
The second picture is the observation door plug, that goes in the small round opening behind the swing door where you look at the fire. There is a kit available part#2552901 - mounting door insulation & observation door plug. They don't show the plug alone although it may be available.
Back in my day Utica used to tell you if you were using the Reillo burner to remove the target wall, if you were using the Beckett burner leave it in.
If you go on line & look up Utica Boilers/products you can see a parts list. Hope this helps.

I recall a thread comparing the Delta T & Delta P concepts. I went back  to Jan 1 & can't seem to find it. Does anybody remember it? I'd like to review it as I remember there was some interesting observations.

Cat Scan

@ March 22, 2014 8:05 AM in 56 year old copper pipe radiant floor heat. Leaks.

Dan calls that a "Cat Scan"


@ March 16, 2014 11:23 AM in What's wrong with this?

Must have been wired by a licensed electrician also.

@ March 16, 2014 11:12 AM in Easy way to clean pigtail / siphon

How about a Tee on top of the syphon, then your presuretrol/vaporstat (you must have a vaporstat) with a plug in the bull. Take out plug, fire boiler, if you get water or steam -- the syphon is clear. Just thinking.

Vanishing water

The first time I saw Dan write about this was in the October 1992 issue of Fuel Oil & Oil Heat -- "When The Water Line Vanishes From That Little Steam Boiler"

Sump pump

@ March 16, 2014 10:35 AM in Has a sink hole ever tried to swallow up a boiler you service?

Is that a steam driven sump pump?

Thanks Hot Rod - Glad to know about this.

@ March 13, 2014 3:35 PM in Anyone familiar with "Heat Load Pro" software?

Whops, I guess not. Sorry


@ March 13, 2014 3:34 PM in Anyone familiar with "Heat Load Pro" software?

I'm going to try to attach an E-Mail I recieved from John concerning your questions. If this is unseccessful you could reach him at his website.

@ March 12, 2014 4:48 PM in Anyone familiar with "Heat Load Pro" software?

Yes the demo is very limited, it's been a while since i have looked at it. The actual Hydronic Design II has a great deal of options available.


@ March 12, 2014 9:46 AM in Anyone familiar with "Heat Load Pro" software?

Glad to hear you purchased it, I think you are going to find it excellent. As I said I've been using it for some time and it hasn't let me down yet.Every job I figured worked like a charm - no issues. I think you would like his HD-2 program also, I live less than 1/2 hour from John, got to remind him about my commission - LOL

Free download

@ March 11, 2014 4:32 PM in Anyone familiar with "Heat Load Pro" software?

I should have mentioned. If you go to John's website - you can download a free demo of his Hydronic Design Studio. If I'm not mistaken there is a short version of the heat loss program there.

I've been using it for some time now & find it very easy to use & quite accurate. I have 3 different programs including Slant Fin's, which I find to be conservative in nature airing on the high side. It always comes in higher than John's Heat Load Pro program. John's even allows you to account for the different R value for studding & rafters. Also it has a very nice program for comparing various different fuels costs. I personally think it is well worth the investment. Excellent for residential use.

I should have added that Sailor is right. If you check taco's cross reference guide it recommends an 006, 007, 008, or a 110 as the appreciate replacement for a B&G Series 100 circ.

Reading list

@ March 11, 2014 1:14 PM in Dans Reading List

The best book I got from your "list" was "The Sultana Tragedy" by Jerry O Potter. I've read it twice & let a lot of my friends borrow it. If you like Steam & the civil war this is a great book!
