Does this look right?

This is in a house a friend of mine is looking at. Doesn't look right to me.
Shouldn't the stem rise off of the top of the boiler?

kcopp

Some brands of Gas boilers take the supply risers off the side. The ECR models are ones that do that.... Dunkirk, Utica, etc.

Thank you.

That style of boiler is very fussy when it comes to near boiler piping Unless it is the smallest in that boiler series both supply tappings should be used to get proper operation. Does he know the specific boiler model number?

Is that a 90 or a T going into the regulator with no drip leg?

It's a tee without a drip leg.
Though I do need to ask, why do stoves, clothes dryers etc not require a drip leg but boilers and water heaters do? Are they not the same exact style gas valve?

GreenGene

I think it varies from state to state and most don't require on appliances except if the manufacturer specifies.

In our case HVAC manufacturers usually do specify them and it's an out if something goes wrong, no drip leg? not our problem the regulator malfunctioned.

408.2 Drips. Where wet gas exists, a drip shall be provided at
any point in the line of pipe where condensate could collect. A
drip shall also be provided at the outlet of the meter and shall be
installed so as to constitute a trap wherein an accumulation of
condensate will shut off the flow of gas before the condensate
will run back into the meter.
408.3 Location of drips. Drips shall be provided with ready
access to permit cleaning or emptying. A drip shall not be located
where the condensate is subject to freezing.
408.4 Sediment trap. Where a sediment trap is not incorporated
as part of the gas utilization equipment, a sediment trap
shall be installed downstream of the equipment shutoff valve as
close to the inlet of the equipment as practical. The sediment
trap shall be either a tee fitting with a capped nipple in the bottom
opening of the run of the tee or other device approved as an
effective sediment trap. Illuminating appliances, ranges,
clothes dryers and outdoor grills need not be so equipped.

I usually find a change of clothes is the best solution to wet gas.

However, in all seriousness, how does one know when wet gas exists?

JUGHNE

Perhaps check the drip trap. Over the years I have found one drip trap with water in it. It was in a dairy barn where the piping supply run a fair length in an unheated attic. It was also a country tap off the transmission main rather thru a city utility, don't know if that makes any difference?

Most gas today is dry gas. The closer you are to the oil and gas fields in the south the more likely you are to get condensibles in the gas (so called "Wet Gas").

Years ago when we had tin meters with leather diaphragms oil was introduced into the gas to insure the flexibility of the leather diaphragms.

Drips for liquids, sediment traps for solids (rust and scale in old gas systems).

Because a lot of gas valves on heating equipment are diaphragm valves the likely hood of a piece of sediment getting across the seat and causing a passing gas valve. Most other appliances use different types of valves. That is why sediment traps are needed on heating equipment. The same for most types of water heater controls they also use a neoprene seat susceptible to getting sediment across the seat hence a sediment trap is needed.

Hope that helps.

The condensates are worth far more than the gas is these days, so there is even less likelihood of them ending up in the distribution system.

I dumped a handful of sawdust out of a dirt leg a few years back. It appears that they ran the gas line over to the stove, fitted the dirt leg, then went upstairs & drilled down to extend it up. By the look of it, it was original to the house, 20's-30's.

That's a great boiler, I have lots of Utica boilers in, but both steam risers have to be piped into the system, Dan says so in his books also. When piped correctly, these boilers will deliver dry steam, efficiently, comfortably and quickly.

Thanks, Bob Gagnon

Looks like a PEG-112. According to the latest I&O manual, here:

http://www.uticaboilers.com/sites/default/files/240009937 PEG-E IOM REV C.pdf

you can get away with just one riser. I like to make the header 2-1/2" on this size though, to slow the steam down a bit more.
